Draka FTTH Solutions Draka Communications is an European leader for any kind of FTTH solutions for the passive optical layer. Draka Communications has developed over the past years a wide range of innovative network concepts and products to deliver sophisticated fiber cable solutions to the end user. Network operators are supported to maximise their revenues and save operation costs. Draka Communications follows its basic strategy and principles in this developing process. One of the key components for GPON FTTH networks is the splitter as depicted in the figure below.
There may be one splitter or several cascaded splitters in an FTTH PON, depending on the network topology. The splitters can be placed in the Central Office, in one of the distribution points (outdoor or indoor). Splitter Portfolio Draka Communications provides a selection of cost effective and high quality splitter devices that enable high performance solutions for Point to Multipoint network. The present document shows only a part of the different splitter that Draka is ready to offer. To meet customer needs Draka Communications is able to offer other kind of preconnectorized solutions. For significant volume we can offer customized splitters with colour that fits perfectly with the colour code used in the optical cables of the operator network. BendBright®
XS One key parameter is the fiber used in the component itself: Draka BendBright®XS fiber (G.657B) has a very good performance versus bending, but at the same time a perfect compatibility with standard single mode fiber (SMF), thanks to its mode field diameter which is very close from SMF. Draka Communications is very please to offer a fiber that presents such benefits.

Splitter Technology The splitter is a bidirectional broadband optical component that has generally one or two input ports and multiple output ports (up to 64). The input (downstream) optical signal is divided among the output ports, allowing multiple subscriber to share a single optical fiber and consequently to share the available bandwidth of that fiber. In the upstream direction, optical signals from a number of ONTs are combined into a single fiber. Splitters are passive devices that do not need power or cooling. They only add loss, mostly due to the fact that they divide the input power. It should be noted that the splitter adds approximately the same loss for light travelling in the upstream direction as it does for downstream direction. There are several technologies to produce the splitters, like Fused Biconic Tapered (FBT) splitters. Another family of splitters is based on integrated optics splitting devices based on Planar Lightwave Circuit (PLC) - Typically used for high split counts output ports. For FBT technology, fibers are heated (by a flame, for instance) and are simultaneously pulled (elongation). The softened parts are formed into a tapered shape. In the tapered part, the distance between cores in fibers becomes close and coupling takes place between the cores. The amount of light coupled varies with the core-to-core proximity and the interaction length.

To make component that has accurate coupling ratios, optical power is launched into a fiber and the output power from a fiber is monitored during the heating and pulling process. Although a 1x2 FBT splitter is common, devices with other coupling ratios are also made, by arranging 1x2’s in a binary tree. Generally speaking, the drawback of FBT is their non-compactness when they are used for a large number of output ports by being cascaded. FBT Coupler Features:
Low insertion loss Low polarization dependent loss High return loss Environmentally stable

PLC are made using tools and processes from the semi-conductor industry and are based on optical waveguide chip. They are made by lithographing silica waveguides on substrates. Optical waveguides are formed on a substrate by a combination of photolithography and etching.
PLC splitter modules have one or two input ports and multiple output ports (N) for the uniform division of an optical signal. The planar waveguide devices feature a compact package (compact management in closures and splice trays) and stable optical parameters, making them suitable for Telecommunications applications. Here is where the PLC technology has a significant advantage; their small physical size has made it possible to place them anywhere in the GPON network. PLC Splitter Features:
Low insertion loss, PDL, Back Reflection Good uniformity Compact package

Introduction
Draka’s BendBright-XS macrobending insensitive single mode
fibers (SMF) answers the market demand for bend-optimized SMF.
This fiber shows perfect performance for the stringent needs in
modern Fiber-To-The Home (FTTH) networks or in more general
access networks (XS=access ). The aim of this Application Note
(AN) is to support the user in the various applications of
BendBright-XS in telecom cables and networks, especially when
they are mixed with conventional SMF. This Application Note starts
with an overview section on the growing impact of macrobending
loss throughout the years and the importance of backwards
compatibility with the SMF applied in the “installed base” networks.
Sections 3, 4, 5 and 6 describe the particular issues related to
macrobending, microbending, fiber connection and
lifetime aspects, respectively. Section 6 covers some miscellaneous
subjects, including an item, dealing with a new characterization
parameter of Multi-Path Interference (MPI). Specific fiber data and
detailed specifications can be found in the product datasheet.
1. Macrobending Loss: Growing Impact
For telecom networks bend loss has hardly been an issue for many
years. Bending the fiber into a helical path is needed to create fiber
over-length allowing cable elongation during installation and a
suitable temperature operating window. This requirement was met
quite easily. Bend radii well over 100 mm did not put high demands
on the fiber bend loss. A further requirement was in the need to
have storage of the fiber over-length in the splice enclosures along
a route. The well-known “100 turns” requirement was created to
represent the total number of fiber storage loops in a route. Radii of
interest decreased to 30 mm, but for a limited length only. A more
severe tightening occurred from the increase of operational
wavelength into the long wavelength 1625 nm band.
The associated extending optical field width at higher wavelengths
makes the fiber more sensitive to bending. This ended up in the
ITU-T Recommendations and IEC standards with the
current requirement of a maximum added loss of 0.1 dB at 1625 nm
for 100 turns with a 30 mm radius.
First generation bend performance improvements were addressed
by standard single mode fiber (SMF) with its simple step-index
profile of the core. The only measures taken by the fiber
manufacturers were the gradual decrease of the nominal mode-field
diameter (MFD) at 1310 nm down to about 9 µm and an increase of
the average cable cut-off wavelength to a value not far below the
lower limit of the operating wavelength window. These transitions
were supported by narrowing production tolerances allowing
prevention of worst case fibers.
The minimum bend radius of 30 mm has had a big impact. In most
fiber management systems this minimum radius can be recognized
in storage cassettes as well as in entrance and exit guides,
resulting in voluminous distribution frames requiring costly space.
More or less, the 30 mm radius has been considered as being a
“natural law” which should not be violated. However, this situation
has come to an end.
Component volume is becoming more and more a decisive factor in
telecom offices, in cabinets and especially in access points and
customer connection boxes in Fiber-To-The-Home networks.
Smaller bending radii may reduce component size and lower the
total cost of ownership further.
Another issue that developed is the ability of the fiber to cope with
installation errors like short radius partial bends and/or “kinks” in the
fiber. For higher level networks these are usually prevented by
requiring well trained installation crews and/or by costly
commissioning procedures. This is no longer affordable in the
optical access networks, where labor and productivity impacts are
much heavier due to the many splitting points and the frequent

network changes inherent to the nature of direct service delivery to
individual end customers. Fast, efficient and low cost installation is
of even more importance here.
Cables with macrobending insensitive fibers will allow typical indoor
installation methods like tight bending around corners, clamping
and even stapling, for which round staples are recommended.
2. Backwards Compatibility and Compliance with International Standards
In the development of low bend loss SMF, Draka has considered
backwards compatibility a key requirement for network operators.
Usually low bend loss is realized by using core modified profiles or
by using the simplest approach, the “high delta” SMF (e.g. pay-off
fibers used in military applications).
Fig. 1 Trench assisted BendBright-XS index profile and modeled fundamental power Pout(r) in % propagating outside radius r for this profile and for an equivalent step-index profile. (Note: 0.5 % power loss corresponds with 0.02 dB)
In this latter case, the refractive index step of conventional step-
index SMF is increased significantly with a simultaneous reduction
of the core size. The resulting low MFD (5 to 6 µm) is hardly
acceptable for applications in telecom networks due to the
mismatch with the SMF installed base. Apart from technical
problems with increased coupling losses, an accompanying cost
factor is in the need for precise registration of the use and stock of
these cables as they should not be mixed with conventional cables.
The first generation of bend loss improved SMF, Draka’s classical
BendBrightTM ESMF, referred to here as BendBright, was launched
in 2002. Its concept is based on the selection process of standard
fibers in combination with some specific in-process conditions. As a
subset of SMF, BendBright fibers are fully backwards compatible
with SMF in all aspects since they are part of the standard product
line. For the BendBright-XS, targeting also the tough requirements
of the access network application, the condition of backwards
compatibility is also maintained. Although this restricted the
development process severely, it showed that the slight reduction of
the MFD to an average value of about 8.8 µm together with the
addition of an optical field confining trench in the optical cladding
just outside of the core (see Figure 1 and Ref. [1]) provided the
required significant bend loss improvement.
As a result, the trench-assisted BendBright-XS can be mixed with
conventional standard SMF, Draka BendBright and/or ESMF,
without violating the requirements for practical installation,
maintenance or operation of the optical network.
Referring to international standards, the trench-assisted
BendBright-XS is fully compliant with the current ITU-T G.652D
Recommendation. With respect to the macrobending loss
requirements, it is evident that BendBright-XS shows
characteristics far beyond this standard. For this characteristic it
provides full compliance with the ITU-T G.657 recommended bend-
insensitive SMF classes. It is superior with respect to the
“G.657_class A” performance and coincides with the much more
stringent “G.657_class B” requirements as indicated at 1550 nm in
Figure 2, which also shows the typical bend loss of BendBright-XS.
Since its introduction in September 2006, BendBright-XS has
demonstrated a remarkable growth (end of 2009: over 330.000 km
of sold fiber), showing the large need for such a robust fiber in
FTTH outdoor and indoor applications. Herewith it shows to be a
leading industrial product, even gathering international recognition
e.g. by being nominated for the best Telecom product in Denmark
at the 2008 Brendsbanddagen. (Denmark is in the leading top five
European FTTH countries).
Furthermore such cables will be of smaller size than cables with
standard fibers because less protection is needed to realize the
required cable specifications.

Fig. 2 BendBright-XS complies with the ITU-T G.657 Recommendation on bend-insensitive SMF for both class A and class B.
The strength of this product is the excellent quality [see Ref. 2]
based on the mature technique by which it is easily produced using
the well known PCVD deposition process. This process offers high
efficiency and large production flexibility; it also releases the lowest
waste to the environment compared to other fiber deposition
processes.
3. Macrobending Loss
Low macrobending loss is needed
i) for storage of fiber, cord or cable over-length in patch-panels or
in splicing cassettes and
ii) in case of single low radius bends as occurring in entrance and
exit guides of fiber management systems and in indoor cable
installations.
For SMF, a commonly applied specification for bending loss is in
the added loss per turn at a given wavelength. This loss increases
linearly with the number of turns, so the specified loss for any
number of turns can be calculated quite easily. As SMF bend loss
increases with wavelength, the specification at the highest
envisioned wavelength, i.e. 1625 nm is most critical. For
applications where 1550 nm is considered as the highest
operational wavelength a specification at this wavelength suffices.
For BendBright-XS, the loss at both wavelengths has been
specified. The ratio between the losses at both wavelengths is not
constant but depends on the bending radius. For 15 mm radius this
ratio is about 5 and for 7.5 mm it has decreased to 2.5.
Fig.3 Comparative macrobending loss overview. The dotted curve
represents the maximum bend loss of a SMF just answering the ITU-T G.652 specification at a 30 mm bend radius.
In Figure 3 an overview is given of the bend loss specification at
1625 nm of BendBright-XS compared with classical BendBright,
standard ESMF and the ITU-T G.652D Recommendation.
Improvement is clearly visible and ranges up to a factor of 100 at a
15 mm radius.
In specifying bend loss in dB/turn, the user must take into account
that the fiber length in the turn is linearly dependent upon the bend
radius. This means that for storage of a fixed length at a lower bend
radius a higher number of turns must be accounted for. In practice
however, the required storage length is decreasing due to ongoing
miniaturization of all components, including the connector patch
panels and splicing sets.
A further effect to be highlighted has to do with the very nature
of bend loss and might be of special relevance when considering
low radius bends. The optical signal escaping from the core due to
the bending of the fiber axis will be reflected at all interfaces with
refractive index differences as e.g. the coating-cladding interface.
Due to the curved reflection surfaces acting quite like a concave
mirror, a significant part of the reflected power passes the core
again and might interfere with the main power stream. As this
interference is dependent upon bend radius and wavelength and
might be either constructive or destructive, this results in a
characteristic undulation (see Ref. [3]) of measured spectral
bending loss curves as shown in Figure 4 for a 7.5 mm radius test.

Fig.4 BendBright-XS spectral macrobending loss for a R=7.5 mm test with 6 full turns in the test set-up.
The undulation depth and the position of the tops are determined by
the specific fiber geometry and core profile and by the specific fiber
deployment. In spectral loss tests, as done for BendBright-XS,
simple curve fitting (see IEC 60793-1-47 Macrobending loss test
method) results in the appropriate loss value. However, when
measuring bend loss with an OTDR, quite large deviations can
occur, especially in case of a single low radius bend where the
undulation depth might be higher.
BendBright-XS fiber shows another strong feature as trench-
assisted bend-insensitive SMF. The PCVD produced profile
guarantees extremely well bending homogeneity. Quantitatively
speaking, the trench-volume variations are lower than 0.1% in the
radial dimension and lower than 0.1% after 1km in the longitudinal
dimension. This extremely good homogeneity level ensures very
stable and robust bend loss performance of BendBright-XS fibers
for indoor application.
4. Microbending Loss
Microbending loss is reduced with a higher fiber MAC value, i.e. the
ratio MFD/CO, just like macrobending loss (see Ref. [4]). As
extensive testing has shown, the optical field confining effect of the
refractive index trench near to the core has a positive effect on
microbending loss as well.
Fig.5 Spectral micobending loss for ESMF and BendBright-XS with ColorLock coating and BendBright-XS with improved ColorLock-XS coating.
Figure 5 shows spectral loss curves from fiber subjected to the
standard Draka microbending test. In this test, 400 m fiber is wound
with high tension on a 60 cm diameter reel covered with low grain
size sandpaper. BendBright-XS fibers show reduced microbending
sensitivity compared to standard ESMF (including a lower slope of
loss versus wavelength), which is further enhanced with the highly
microbending improved coating ColorLock-XS.
Microbending is a less defined deformation of the fiber axis for
which some test methods are suggested in IEC Technical Report
TR 62221.
Other test methods have also been applied to evaluate the losses
originating from micro-deformations as can occur in practice. Some
examples are the “pin-array” test and the “kink” test. The “kink test”
might give a good impression of the effects occurring in case of
possible sharp bending, e.g. in splice cassettes. In this test, a
coated fiber is loosely pressed against a low radius pin over an
angle of about 45 degrees. The fiber has some free space due to
the distance of about 0.7 mm between the pin surface and the
pressing surface resulting in a smaller effective bend angle as is the
case in usual cable structures. The test is repeated several times
and the results are averaged.
In Figure 6, some test results are shown applying a 1.5 and a 2 mm
radius pin respectively. The tested fibers were nominal MAC value
fibers from both BendBright-XS and the classical BendBright
product line. The improvement originating from the trench is
impressive.

Fig.6 Spectral “kink loss” curve for a BendBright-XS fiber pressed against an R=1.5 mm pin. In the inset, the losses at 1550 nm are given for some nominal BendBright-XS and BendBright fibers.
In case of sharp incidental bends, BendBright-XS fiber responds
with a limited excess loss only. In case of a standard step-index
SMF, the inserted loss would certainly have initiated a system
alarm.
Seen from this aspect, the new trench-assisted BendBright-XS
fiber is very installer friendly and forgiving. However, this does not
mean that fiber mounting should be done carelessly.
5. Fiber Connection
Fiber connection is of high relevance in installing, operating and
maintaining an optical network. Not only for splicing consecutive or
branched-out cable sections, but also in connecting cabled fibers to
transceiver or splitter pigtails. The connection might be from
connectors, mechanical splicing or fusion splices. The inter-
compatibility of legacy fiber must always be considered when
introducing a newer fiber type, even if improving its characteristics.
Therefore, it makes sense to check the impact of the BendBright-
XS on each of these methods.
5.1: connectors
In cleaving, polishing and processing of the fiber end-face,
BendBright-XS does not differ from standard SMF. The surface of
the trench is very small compared with the total fiber surface, so the
small differences in material do not affect any of the processing
steps significantly. This has been verified by making a series of
connectors and testing the connection results in terms of insertion
and reflection loss. No differences in characteristics resulted.
As for the reflection loss it should be noted that one of the methods
to suppress end face reflection i.e. by making one or more small
radius loops in the fiber downstream the connector to be tested,
does not work anymore. Alternative methods like the use of index
matching oil or gels should be applied.
An interesting part of this test cycle is the tested patch-cord bend
loss. In this procedure, a cord is bent over quite small radii at
different angles as represented in Table I. The extremely low losses
correspond fully with the results shown in Figure 3.

5.2: mechanical splices
Just like the results for making connectors, the use of BendBright-
XS does not differ from the use of standard SMF. For verification, a
series of mechanical splices were been made, the result of which is
represented in Table II. The average value and maximum value
over 5 installations were both within the specifications for this type
of mechanical splice.

5.3: fusion splicing
Draka and all major splice machine manufacturers have conducted
extensive splice testing of BendBright-XS and have found that all
machines are capable of splicing BendBright-XS effectively. This
includes splicing BendBright-XS to itself, to other bend-insensitive
fibers, and to standard single-mode fibers. Some single fiber splice
machines use (proprietary) profile or core recognition to align fibers.
If these machines do not have updated software it is possible that
BendBright-XS may not be recognized, because the trench in the
profile may cause errors in the recognition software (see figure 7). If
this is encountered, this can easily be overcome by simply changing
the machine setting (see table III).
Table III lists most common splice machines on the market. It is
intended to provide guidance and recommendations in case
alternative settings are required. It should be noted that the splice
machine manufacturers have already updated or are in the process
of updating software to BendBright-XS. Standard settings can be
used for outside diameter/cladding alignment machines, including
mass fusion splice machines.
Although good results can be achieved with older splicing sets
applying the MMF arc settings, Draka recommends applying
modern splicers that support BendBright-XS, see Table III.
Note: Do not hesitate to contact the local distributor of the
splicing equipment for up-to-date information and equipment
updating procedures.

Splice test results:
As BendBright-XS allows a backwards compatibility with already
deployed fibers (standard Single-mode fiber), it is also important to
guarantee compatibility with existing deployment procedure. As far
as fusion splicing operations is concerned, it is important to ensure
that splicing conditions do not differ that much when BendBright-
XS is spliced to another fiber. Two possible splicing cases are
distinguished:
• Splicing BendBright-XS to standard single-mode fibers
• Splicing BendBright-XS to itself
5.3-1: splicing BendBright-XS to ESMF
Splicing the trench-assisted BendBright-XS fiber to a standard
SMF will occur frequently at the edge of an access network or when
splicing fiber pigtails in passive components like power splitters.
Figure 8 shows the result of splice test performed by Draka
between different commercial available G.652D fibers and
BendBright-XS, performed with several fusion splicers.
Measurement performed with bi-directional OTDR method.
5.3-2: splicing BendBright-XS to BendBright-XS
Splicing BendBright-XS to itself works like splicing every other
standard SMF in nowadays installation practice. Given that spliced
fibers have identical chemical compositions, splicing conditions are
usually more relaxed than splicing with dissimilar fiber. As a result,
fusion splicing usually exhibits slightly better performance than
when splicing with heterogeneous fibers. This is proven by below
Figure 8 showing statistics of a large amount of splicing tests on
different commercially available splicing machines. Measurement
performed with bi-directional OTDR method.
Note: Individual results for particular splice machines are
available on request.

Table III: Recommended splice machine settings for BendBright-XS.
Fig. 8 Splice loss distribution of BendBright-XS to itself and to multiple
commercial G.652D fibers using different splice machines at 1550nm.
The above reported splice test results (Figure 8) are obtained in a laboratory. Splicing in field
circumstances will result in the same values when it has been
secured that all equipment is well maintained and in good condition,
operators are well-trained and splicing is performed in a clean
environment.
5.3-3: OTDR commissioning procedure
During installation, the splice loss is predicted by the optical image
processing system of the splicer unit. Based on this prediction the
splice can be approved or rejected. When commissioning an optical
link, splice losses usually are checked again by OTDR testing from
either one side or from two sides of the fiber link. For testing splices
in networks with optical splitters special procedures do exist.
When measuring splice loss with an OTDR, peculiar effects can
occur. Depending upon the direction of testing, apparent gain or
apparent high losses can be observed. The main reason for this is
in the strong dependency of backscatter level on the MFD value. If
the spliced fibers have different MFD values the backscatter level of
both fibers will differ. This impacts the ability of the OTDR to
measure the splice loss from one direction. More details are given
in Refs [5] and [6].

Fig. 9 Measured uni-directional OTDR gain or loss for an ideal splice at 1550 nm determined from a 9.0 µm MFD standard SMF launching into other standard SMF and into BendBright-XS fibers with various MFD values indicated on the horizontal axis.
Also for BendBright-XS, backscatter level is mainly determined by
MFD. This is depicted in more detail in Figure 9. A standard SMF
launch fiber with a 9.0 µm MFD is spliced to a series of other SMF
with deviating MFD values. Applying the method used in Ref [7], the
apparent loss (dB >0) or gain (dB <0), referred to the launch fiber
can be derived for each fiber. Good correspondence shows with the
expected theoretical value based on MFD differences (see Ref [5],
Eq. 5), which is also represented in Figure 9. These results show
that the trench-assisted BendBright-XS behaves just like a
standard SMF with respect to OTDR splice monitoring.
Since BendBright-XS has a slightly lower nominal MFD then
conventional SMF, more splices will be noticed with an apparent
gain when testing from the side of the conventional SMF. In case of
a commissioning procedure requiring the use of cost-effective
single sided OTDR monitoring, this difference in average value of
MFD distribution has to be taken into account. Methods to cope with
this do not differ from situations where different standard SMF fibers
with a difference in nominal MFD value are spliced (see also Ref. [5]).
6. Lifetime Aspects
These requirements have been derived from a worst case network
situation defined as:
“all fibers in a cable observe over the entire length and during the entire lifetime of e.g. 20 years, a constant strain of maximum 1/3 of the 1% proof-test value”
For modern optical fibers this requirement is met by applying high
quality materials and clean processes. Verification is done by proof-
testing the fibers resulting in a sufficiently low number of breaks per
preform pull. Meeting this requirement for a 1% strain at proof-test,
insures that the fiber can withstand a 1/3 % strain over its whole
cross-section, length and lifetime.
When bending a fiber in a storage cassette the following main
considerations apply:
1- Usually there is no axial stress on the fiber, so consequently
the main cause for strain is the bending itself. By simple
geometrical rules it can be calculated that a 1/3 % strain is reached
at the outer circumference of a 125 µm OD fiber for a bend radius of
18.75 mm. Bending the fiber over its whole length on this diameter
will not impose any additional impact on the lifetime compared with
the criteria mentioned above. On the contrary, the average stress is
even less as the 1/3 % strain is present in a very small part of the
fiber’s outer surface only.
When deploying SMF in storage cassettes or in case of incidental
bends, stress is applied to the outer circumference of the fiber
causing strain in the glass material (see Figure 10).
Fig. 10 Strain in the outer surface of the fiber by bending the fiber axis with a radius
Reducing the current minimum bend radius from 30 mm to 15 mm
or even lower, might raise some questions on the lifetime of the
fiber. For modern SMF however, there is no reason for this concern
With respect to strength, BendBright-XS gets the same high
quality processing as the Draka standard SMF. This is sufficient to
guarantee its lifetime in all situations in a telecom network, including
access networks with much more rugged environments. To explain
this, let’s start with an assessment of current strength requirements.

2- The bent fiber length in a storage cassette is a very short
section of the total fiber length only. So, the failure probability is
accordingly lower.
Both considerations apply when calculating the failure probability of
a short fiber length stored in a cassette of a fiber management
system. In Ref. [8] a more complete model has been described
starting from the outside plant failure probability as indicated by the
network operator. For a rather extended network containing 5000
storage cassettes and a failure probability per cassette of 0.001 %
in 20 years, i.e. one single spontaneous breakage in one of the
cassettes in 20 years in 20 of these networks, the minimum bend
radius is represented in Figure 11.
It is evident that this minimum radius depends upon the length of
the stored fiber in the cassette. The other parameter that governs
the minimum bending radius is the stress corrosion susceptibility n
(fatigue parameter). For BendBright-XS the value of the “dynamic”
susceptibility is >20 (see datasheet) whereas the “static” value is
>23. Note that the minimum dynamic stress corrosion susceptibility
coefficient is 18 according to IEC product specification 60793-2-50
and Telcordia GR-20-CORE specifications.
Depending upon the envisioned safety margin, different values can
be used. Since storage aging in most cases is a static
phenomenon, the use of the higher static fatigue parameter n=29
might be justified. The lower value of n=18 might be used as a
“worst case”. Dependent upon these considerations the curves in
Figure 11 demonstrate that for this typical network and the
accepted very low failure rate a storage length of, for example, 100
cm of fiber at a 15 mm radius is a safe situation. However, storage
of 100 cm of fiber at a radius of 10 mm is also safe if the higher n-
values are ascertained *).
Fig. 11 Minimum bending radius for storage of the BendBright-XS with a 20 years failure probability of < 0.001.
The curves in Figure 11 also show that for much shorter bend
lengths, such as 90 degree bends in exit and entrance ports of a
fiber management system the minimum radius can be much
shorter. Referring to the kink loss situation as indicated in Figure 6,
detailed calculations reveal that even in these cases, lifetime is not
significantly affected (see e.g. Ref. [9]; Fig. 9). A nice illustration of
this comes from a simple long term experiment started at Draka
Denmark in the early nineties of the last century. A series of
different diameter mandrels, diameters ranging from 2.8 to 4.2 mm,
10 of each and each mandrel with 30 windings were stored in a
room temperature environment. In the D=2.8 mm and D=3.0 mm
series mandrels 5 breaks occurred after 11 and 28 days,
respectively. However, from the D ≥ 3.4 mm mandrels no breaks
were detected up till now, i.e. 16 years later!
In general it can be stated that lifetime considerations on fibers
stored in short bend radius fiber management systems differ
significantly from lifetime considerations of cabled fibers. For
storage in fiber management systems, a higher strain may be
present on short lengths, whereas for cables a lower strain and a
much longer length apply. As for lifetime prediction however, similar
calculation models can be applied.
*) Note that at this specific bend radius, the bend loss in “live” fibers cannot be neglected anymore. For a for 100 cm storage with a bend radius of 10 mm, the specified maximum bend loss becomes as high as 0.8 dB at 1550 nm.
Single bend failure rate.
Based on Ref. [10] Draka calculated the failure rate at the various
bend radii. The Parts Per Million (PPM) rate is the most
straightforward way to explain the reliability in small bends. Table IV
quantifies the risks of failure at various bend radii. For example, for
every one million bends at a 10 mm bare fiber bend radius, there is
0.8 predicted failures over a 25 years life. This assumes the fiber is
bent at that radius over the entire 25 years.

7. Miscellaneous
The improved macrobending behavior of BendBright-XS can also
have impact other areas aspects, which are highlighted below.
7.1 Fiber and cable cut-off measurement.
In the cut-off region of a SMF, optical power is propagated not only
by the fundamental mode, but also by higher order modes. For a
standard step-index SMF the two LP11 higher order modes are the
dominant ones just below the cut-off wavelength. In the bend
reference method of IEC and ITU-T standardized cut-off
wavelength test methods power is split in equal parts over the
three propagating modes. This results in a spectral curve “hump”
with a top value of 10xlog(3) = 4.7 dB. The cut-off wavelength
follows from the higher wavelength at 0.1 dB height of this hump.
For trench-assisted BendBright-XS, the cut-off phenomena differ
significantly from those for a conventional step-index core profile
SMF. As the bend loss of the higher order modes is influenced by
the trench also, the wavelength width of the cut-off region is
broadened significantly leading to a much lower “hump” value when
applying the bend reference method. In addition, due to interference
undulation in the measured cut-off curve can occur resulting in a
“dispersed hump” with a much lower maximum value, even far
below the minimum height of 2 dB as required in the IEC standard
for this test method. Applying the multimode reference method (see
Ref. [11]) does not have this drawback and is recommended for this
test, both for the fiber and for the cable cut-off wavelength. This
recommendation will also be implemented in next edition of the
indicated IEC standard.
7.2 Multi-Path Interference
Multi Path Interference (MPI) has been discussed for the last 20
years and the term encompasses a wide variety of phenomena
which translate in interferences between the optical signal and
weak, parasitic time-delayed replica. The induced fluctuations act
as noise in transmission and therefore degrade the system
performances.
MPI has recently received a renewed attention in the access
network context. In this case, one refers to coherent MPI because
interferences occur between co-propagating modes (Fig.12).
Fig. 12 MPI/Modal noise in FTTH context.
The interest expressed comes from the fact that MPI is a well-
known way to estimate the impact of a few mode behavior when the
system is operated lower or close to the cut-off wavelength. MPI
gives a better view on systems impairments than just a cut-off
characterization. In other words, a known MPI level relates to a
power penalty and therefore to a system budget.
Simulating extreme field installations (see Figures 13-14),
BendBright-XS cables have been submitted to various tests, each
one investigating a particular source of MPI that will be encountered
in real systems (see Ref. [12]).

All these measurements have been performed using the power
fluctuation method (see Ref. [13], known among the classical MPI
characterization techniques to be the best one to capture the true
essence of coherent MPI, all the other ones leading to severe
underestimations. Table V MPI levels measured at 1310 nm for cable stapling,
bending and sharp turns experiments
1310 nm Stapling Loops Sharp Turns 3 mm cable < -45 dB < -40 dB < -40 dB 5 mm cable < - 40dB < -40 dB < -40 dB
Table V lists all the MPI values measured for the 3 and 5 mm
BendBright-XS indoor cables. Even though these experiments
represent extreme installation conditions, the MPI levels found are
well below –30 dB which makes BendBright-XS fully compatible
with successful FTTH deployments (see Ref. [12]).
7.3 Use of fiber identifiers
The enhanced bending performance of BendBright-XS will
diminish the signal received with fiber identifiers. This might cause a
sensitivity problem dependent upon the type of use and the type of
tap-off mechanism. To investigate this, several identifiers were
tested:
- Tests with the Wilcom F 6225 identifier showed that working
with BendBright-XS is possible with normal identifier settings for
both the 250 µm OD primary coated fiber and a 2 mm buffered
patch-cord.
- Tests with done also with the EXFO LFD-250 "clip-on" detector
and the LFD-300 FiberFinder. Both work well as clip-on device to
a sensitivity level of about -30 dBm at 1550 nm. For providing the
appropriate power level software modifications will be required.
7.4 High power induced aging
In view of the foreseen up-grading of networks with distributed or
lumped Raman amplifiers, much attention is given currently to the
effect of the use of high power pump lasers at e.g. 1460 nm. An
annoying side effect might be that loss of power at low radius bends
can initiate an accelerated aging of the coating and in some cases
eventually lead to fiber breakage or even start of fire in some older
types of tightly coated fiber.
It will be evident that the use of fibers with improved macrobending
behavior, like trench-assisted BendBright-XS are much less
vulnerable to this effect, see Figure 15 showing BendBright-XS in
comparison with a regular G.652 fiber (see also Ref. [2, 14]. In this
figure different failure definitions have been applied (see Ref. [15]):
R1: catastrophic failure of the glass fiber mimicking a fiber break;
R2: catastrophic damage to the fiber coating;
R3: accelerated ageing of the coating.

power (R3) at 8 mm diameter compared to G.652 fiber (bottom).
