Bend insensitive single-mode-fiber - G.657.A2 BIF SMF with min. specified radius of 7,5 to 10mm is well suitable for all demanding access requirements

- G.657.B2&B3 BIF SMF are not necessarily compatible with the standard G.652 family due to Japanese low MFD specification, which is part of these sub-categories. G.657.B2 fibers already perform very well in-building applications (G.657.B3 is not necessary)

- BendBright-XS(fulfilling G.657.A2&B2)is today the perfect match for access as well inbuilding,allowing end-to-end solutions. - Bending radius of 7.5mm is feasible and do not affect the lifetime. - Draka‘ s BendBright-Elite offers G.657.B3 specification (min. bending radius 5mm) with enlarged proof test of 2% for better lifetime protection of this fiber type.

Operators already deploying BendBright-XS:

AT&T, France Telecom, Telefonica

Our Fiber Solution

BendBright-XS value proposition –  100x less sensitive to bending losses –  Fully compatible with G.652.D / ESMF –  Lowest total installation cost for operator –  Allows use of smaller ONT, patch panels etc.

Definitions / What Is FTTx?

FTTH – Fiber to the Home FTTB – Fiber to the Building / Basement (not included FTTO) FTTC – Fiber to the Curb (last distribution point / node) FTTN – Fiber to the Node

–  A fiber based system in which the optical network unit is located in a node that may serve 50 to 500 homes. The distinction between FTTN and FTTC is the number of homes used by the optical unit. For FTTC the number typically range from 4 to 32.

FTTP – Fiber to the Premises – Similar to FTTH but more inclusive – the

subscriber premises may be retail or other small businesses as well as residential customers.

FTTx – Refers to FTTB, FTTC, FTTN and FTTP

Key Drivers

Globally, bandwidth demand continues to accelerate driven by quadruple play (voice, video, data & wireless).

–  Regional development varies but long-term global developments are evident.

–  Access development will eventually drive growth in long-lines as the pipes fill.

–  New services ultimately require fiber based infrastructure. Some will migrate to FTTH, others will evolve into hybrid systems. More bandwidth capability will be the driver.

20

Key Drivers

Economics are critical, returns on investments are under scrutiny.

–  Service providers and network operators must improve on the current returns in order to justify future development.

•  Value proposition to the subscriber is the critical element. – CAPEX and OPEX costs must come down to support the

consumer driven economic model. •  GDP growth needs to continue. Inflation has to be kept in check.

– High inflation / recession will have a high impact on development. –  Content convergence will force industry consolidations. –  The case for winners and losers is still developing

21

Key Drivers

Political issues are significant – Legacy PTT’s are fighting the EU open market

tactic, which stalls FTTx development. – Protectionism in lieu of open competition is the

landscape and the open market is winning. – State and local regulators can open and close

access to FTTx in the United States

22

Business Protection

Consumer Protection

Investment Protection

•  US –  August 2003 Terennial Review Order basically

bundles FTTx elements. –  Video is a local (state) issue.

•  Europe –  Broadband roll out just started after

liberalization in 1998. –  Players ask for investment protection, mainly

DT in Germany. –  EU wants to keep business protection and as a

result traditional Telco’s don’t move. •  Middle East

–  Investment protection, wealthy parties control the game.

•  Asia Pacific –  Consumer protection. –  Heavy push on fiber investments due to dense

population.

Key Drivers Regulation Policies

23

Key Drivers

The customers are changing

– Video content will drive who will play. Voice has become the “lost leader”.

– In EMEA, legacy PTT’s are standing on the side lines while new independents step in. Old relationships become less meaningful.

24

Key Drivers

Competition varies

– Some competitors provide total solutions, others specialize in key components

– All propositions will varie from region to region.

Advantage of bend-insensitive fibre

Smaller component volume : €€ “cost of ownership”

More forgiving fibre: less re-work €€ “labour cost”

Easy fibre handling: cheaper installation

Flextube designs already provide significant reduction in size compared to standard loose tube ones

e.g. 720 fiber dielectric cable

More aggressive designs yielding breakthrough size reduction with G.657.A2&B2 unique bend loss attributes! Optimizing compact cables for overcrowded ducts (duct saving) in large cities around the globe

FTTH is the target architecture for most of telecom operators in the world…

31

  Basement box: it contains the secondary pre-connectorized splitter of the PON and it is installed in the basement

  Vertical rise: cabled with a multi-fiber cable or single-fiber cables (small buildings, maintenance) using the existing ducts. The cables can be connectorized at the box side end in the factory or in the field (by means of fusion type or mechanical connectors)

  Fiber extraction at floor: all the required fibers are extracted at each floor and are protected with a suitable system

or Multi-fiber

cable

Customer connection: it is performed “on demand”, splicing a single-fiber cable, installed in the horizontal path, with the extracted fiber (if multi-fiber cable solution is used in the vertical rise); the splice has to be properly protected and inserted in the customer existing tube.

When single-fiber cable is used for the vertical cabling, the customer is directly connected from the basement box without splices.

At the user end the customer drop is connectorized, in the factory or in the field, and installed in the outlet.

32

-it consists in a fibers loosely assembly into an external sheath

-the fibers can be ruggedized or suitable strength member can be put inside the cable structure

-suitable for high count customers buildings -must be flexible and robust

Fibers are extracted from the cable for customer connection through a splice with the customer cable

Suitable protection must be used at the extraction and splicing points when sharing of infrastructure with other services can be dangerous

Multi-fiber cables

33

Single-fiber cables:

-it consists in a reinforced structure containing one (or more) fiber (G.657A type)

-maximum size 2 mm, compatible with the small size of the existing customers tubes

-suitable for medium-small size buildings -it can reach customer directly from the basement box

or from the extraction point of the multi-fiber cable at the floor level

-suitable for installation in very tortuous and congested paths in which tension, bending and compression can reach very high level

-the external sheath compound shows low friction properties
