4.3 Boards
ZXONE 8000 equipment provide multi-functional boards including optical wavelength
conversion board, branch board, line board, optical multiplexing and demulitiplexing
board, optical add/drop multiplexing board (fixed and reconfigurable), optical power
amplifying board, optical protection board, system control, monitoring, and
communication board.
4.3.1 Optical Transponder
The main function of optical transponder is to aggregation or converts the accessed one
or multiple client-side signals and put out DWDM standard wavelength as ITU-T G.694.1
suggested, so that the multiplexing unit can take wavelength multiplexing of optical
signals of different wavelengths. All wavelength transponder units of ZXONE 8000
equipment are transceivers which can implement the reverse process of the above.
Main functions of optical transponder board are shown in Table 4-9:

6.2 Optical-layer Dispatching
ZXONE 8000 uses ROADM for dynamic optical-layer dispatching.
ROADM is divided into two-degree ROADM (also called linear ROADM) and
multi-degree ROADM (also called HUB ROADM) according to network direction number.
Two-degree ROADM supports two network directions and is mainly applied to chain and
ring networks. Multi-degree ROADM supports more than two network directions and is
mainly applied to such complex topologies as tangent ring, intersectant ring and MESH
network.
ZXONE 8000 offers two linear ROADM solutions: One is PLC-based ROADM subsystem
taking WBM as the core, the other is WSS-based ROADM subsystem taking WSU as the
core.
WSS-based ROADM solution has two types: One is WSUD (MD8A1)-based two-degree
ROADM system which can be configured with OMU (Coupler) + tunable OTU for
colorless port, and the other is PDU + WSUA/E-based 2~9-degree or WSUB (2~20
degree) ROADM system which can be configured with different local dropping units for
colored/directional and colorless/directionless ports. The latter is applied to ring and
mesh networks. It has powerful flexibility and wavelength dispatching function to support
core network.
PLC-based ROADM solution has low cost and only supports two degree. It is applied to
ring and chain networks to replace previous OADM sites. It does not support
directionless and colorless ports.
ZXONE 8000 Product Description
78 ZTE Confidential Proprietary
Directionless: It means that any local port can add/drop the service of any direction.
Colorless: It means that any local port can add/drop any wavelength.
6.2.1 Two-degree (in the ring) wavelength dispatching
Two-degree dispatching is to dispatch wavelengths in two directions. ZXONE 8000 uses
WSUD for two-degree (in the ring) dynamic wavelength dispatching, in other words,
dynamically add/drop, pass through and block services wavelengths, and equalize and
inspect channel optical power.

Eastward and westward service wavelengths directly use NM software to make dynamic
adding/dropping, pass-through, blocking, channel optical power equalization and
inspection, dynamically adjusting wavelength status in a remote way.
Adding unit employs coupler multiplexer and tunable-wavelength service board for
colorless and directionless port, and dropping unit employs WSUD/E or cascade
WSUDE for such a function.

4-direction service wavelengths directly use NM software to make dynamic
adding/dropping, pass-through, blocking, channel optical power equalization and
inspection, dynamically adjusting wavelength status in a remote way.
Line side employs PDU and WSUA/E to dynamically dispatch the wavelengths in

6.3 Electrical-layer dispatching
ZXONE 8000 can dispatch ODU0/1/2/2e/3/4/flex signals via switching board. It supports
at most 9.4Tbit/s switching & dispatching capacity.
Electrical-layer dispatching supports three typical application scenarios:
Pass through client-side service at local site: Input the service via a client-side port
of electrical switching matrix and output it via another client-side port at local site, in
other words, the service is not transported via the fiber.
Add/drop client-side service: Transmit the service of other sites to line side of
electrical switching matrix of local site via the fiber, and then output it via electrical
switching matrix at client side; or input client service at client side of electrical
switching matrix of local site, and then send it to other sites via the fiber.
Pass through line-side service at local site: Wavelength service from other sites is
not added or dropped at local site, but is dispatched to other directions via electrical
switching matrix, or is relayed or switched to other wavelengths.
6.4 L2 switching
ZXONE 8000 provides the board-level L2 switching to multiplex and demultiplex
24-channel GE signals (or 8-channel GE signals) or 1-channel 10G (or 2-channel 10G) to
2-channel OTU2 signals. The working principle is shown as Figure 6-4:

6.5 Optical Power Amplification
6.5.1 Erbium-Doped Fiber Amplifier
ZXONE 8000 system uses mature EDFA (Erbium-Doped Fiber Amplifier) technology to
realize long/medium-distance transmission. EDFA makes the signal gain per channel
independent from the total count of the channels in the fiber by using gain locking
technology and transient control technology. At the same time, when some channels are
added or lost suddenly, it can avoid the interferences to the existing channel.
At the same time, the coupling between EDFA and fiber is very good. The characteristic
of EDFA is good for its high gain, less noise, large bandwidth, high output power, high
power efficiency, low insertion loss and insensitivity to polarization.
ZXONE 8000 system provides multiple sorts of EDFA and EDFA with high output power.
It supports the amplification of 100GHz/50GHz spacing signals on C band which are
proposed in ITU-T G.694.1.
6.5.2 Raman Amplification Technology
In long-distance DWDM system, radiation caused by EDFA will restricts entire system
performance. By using distributed RAMAN amplifier (DRA), ZXONE 8000 effectively
reduces system noise and nonlinear effect via EDFA+DRA technology (i.e. use EOA
board and DRA board together). This method effectively improves optical amplifying
performance of the long-distance DWDM system.
ZXONE 8000 also provides HNA(hybrid node amplifier) for long-distance span, as using
ZXONE 8000 Product Description
ZTE Confidential Proprietary 85
on board integrates both the DRA and EDFA function, it really improves the system
integration and transmission performance.
6.6 Forward Error Correction
ZXONE 8000 provides optical wavelength transponder unit and branch unit with FEC
(Forward Error Correction), AFEC (Advanced Forward Error Correction) and SD-FEC
(Soft Decision FEC) services. This configuration on one hand reduces the requirements
for optical signal to noise ratio (OSNR) of receiver; on the other hand it extends the
transport distance between all optical amplification section and regeneration. At the
same time, it decreases the error rate caused b transmission and enhances the transport
quality of DWDM transport network.
By using AFEC algorithm, it effectively improves OSNR 7 dB~9 dB.
By using SD-FEC algorithm, the NCG is 11.1dB.
6.7 Tunable Wavelength
ZXONE 8000 equipment is designed with 100Gbit/s, 40Gbit/s and 10Gbit/s wavelength
conversion units to change wavelength. The maximum value of 100Gbit/s optical
wavelength conversion unit is C waveband 50GHz interval 80wave. The maximum value
of 40Gbit/s or 10Gbit/s optical wavelength conversion unit is C waveband 50GHz interval
96 wave. The maximum value of 2.5Gbit/s optical wavelength conversion unit is C
waveband 100Hz interval 16 wave. The optical wavelength conversion unit with variable
wavelength can either be service module directly or spare components used to replace
the optical wavelength conversion unit of different wavelengths to reduce the number of
optical wavelength conversion unit and decrease the component costs.
6.8 Optical Layer Protection Service
ZXONE 8000 is capable of the following manners of optical layer protection: 1+1
protection (O-SNCP), multiplex section 1+1 protection
ZXONE 8000 Product Description
86 ZTE Confidential Proprietary
6.8.1 Channel 1+1 Protection (O-SNCP)
Optical channel 1+1 protection is implemented by SOP board on the basis of concurrent
delivery and primary reception theory. At the sending end, the protected services are split
into two parts via the coupler on SOP board and goes into two OTUs (OTU redundant
mode) for different sending path. At the receiving end, signals with better quality will be
received by using primary circuit on SOP board. Take the protection of a group of service
as an example. As Figure 6-5 shows:

equipment protection (OTU is in redundant mode)
6.8.2 MS 1+1 Protection
Optical MS 1+1 protection keeps section-by-section 1+1 protection mode. According to
different locations of EOA board, MS 1+1 protection consists of EDFA shared
configuration mode and EDFA redundant configuration mode. As Figure 6-6 and Figure

6.10 Dispersion Management
For ZXONE 8000, the maximum dispersion tolerance of 2.5Gbit/s, 10Gbit/s, 40Gbit/s
and 100Gbit/s systems is 12800ps(around 640km), 800ps/1600ps(about40/80km),
+/-1000ps/+/-800ps and +/-70000ps respectively. When system transmission is longer,
restriction to dispersion must be considered for 10Gbit/s system, 40Gbit/s system
specially.
According to specific requirements, ZXONE 8000 configures related dispersion
compensation module to make up bandwidth dispersion.
For 40Gbit/s system, the adjustable dispersion compensation module inbuilt in the
receiving unit can automatically control dispersion compensation. So the 40Gbit/s
system can be compatible with 10Gbit/s system.
For 100Gbit/s system, using the high speed DSP technology, the dispersion
ZXONE 8000 Product Description
ZTE Confidential Proprietary 89
compensation capability can support +/-70000ps (around 3500km), so which doesn’t
need the additional compensation usually.
The dispersion compensation module in the s10G/40G system can be configured in the
way shown in Figure 6-9.
Figure 6-9 Configuration of Dispersion Compensation
6.11 Automatic Power Shutdown/Reduction
Assisted by network management software, ZXONE 8000 supports Automatic Power
Shutdown (APSD) and Automatic Power Reduction (APR). When the inspection board
with optical performance inspection service (e.g. OPM board) finds lightless line, the
inspection board will automatically send notification to SNP. When SNP receives the
information, it will make the executive board (EOA board) to reduce power or shut down
power. This mechanism prevents people’s eyes from being hurt by laser. When the
failure is recovered, the system can come to normal operation automatically (or
manually).
APR is used on one optical transmission section (OTS). When any OTS breaks down,
other OTS and downstream alarm won’t be affected. In the course of APR processing,
Clamp output of EOA amplifier of each receiving end is guaranteed. The EOA amplifier
of the sending end is shut down.
OTU module and branch module of ZXONE 8000 can also provide APSD service. When
one client optical interface of the peer-end OTU module receives does not have input
signal, the corresponding client sending optical port of local OTU module will shut down
the laser automatically.
ZXONE 8000 Product Description
90 ZTE Confidential Proprietary
When WDM optical receiving port of OTU module does not have signals, all client
sending optical ports will shut down the laser automatically.
6.12 Optical Power Management
Optical power management service consists of line attenuation control service (LAC) and
automatic gain control service (AGC).
6.12.1 LAC Service
As per line optical power inspection situation, the network management adjusts EVOA of
LAC to guarantee all cross-section power points, receiving power of the receiving end
and OSNR to keep normal values.
6.12.2 AGC Service
EDFA of ZXONE 8000 uses gain lock amplifying mode. The value of the gain lock can
changed flexibly to satisfy the requirements of relays with different distances. Within all
input and all working temperature, the resolution of the gain adjustment is 0.1dB.
Despite the wavelength of fiber, AGC can implement gain lock of single channel. Any
wave increase or drop, or fluctuation of optical signal of one or multiple wavelength will
not influence signal gain of other channels.
6.13 Automatic Performance Optimization (APO)
ZXONE 8000 provides MS and channel-based APO service.
MS-based power management: build and keep the optimized status of MS group
line power.
Channel-based power management: build and keep the power balance in the
channel.
ZXONE 8000 Product Description
ZTE Confidential Proprietary 91
6.14 OMS Layer Power Management
If transmission distance is long and many amplifier sites in the middle, the problems of
optical power become more apparent. For example, optical power difference of every
channel becomes larger. In this case, the Automatic Power Optimization (APO) is
necessary to WDM system.
ZXONE 8000 provides MS and channel-based APO service.
MS-based power management: build and keep the optimized status of Multiplexed
Section (MS) power.
Channel-based power management: build and keep the power balance in the
channel.
6.14.1 OMS Layer Power Management
OMS layer power management is implemented based upon power management domain.
The power management domain refers to one MS, i.e. OMS between two OTMs or
FOADMs (ROADM). It requires independent performance in each power management
domain, e.g. power consumption and SNR.
The MS power management service guarantees a constant difference between all gains
and line loss of every channel.
In real optical line, when the difference of gain loss satisfies the condition of initiating MS
power management, power optimization will start. When the difference of gain loss
meets the requirement of MS power management, the optimization is over.
MS power management can be implemented by using module and network management
software together.
Module
Module implements power monitoring and adjustment, including LAC, EOA and DRA.
Network Management Software
ZXONE 8000 Product Description
92 ZTE Confidential Proprietary
Set all parameters of power management; query existing power status; send power
management command to module; support automatic and manual adjustment.
6.14.2 OCH Layer Power Management
OCH layer power management focuses on the power in OCh. OCh is the section
between line ports of optical transponder unit which implementing end-to-end connection
of all signals (PDH, SDH and ATM)
Channel layer power management consists of fixed power compensation and dynamic
channel power management. Fixed power compensation uses intelligent optical amplifier
to ensure the gain flatness of the amplifier. Dynamic channel power management uses
power pre-optimization technology and dynamic gain optimization technology to adjust
the optical power of all signal channels. In this way, the optical power of all signal
channels at the system optical receiving end can be balanced.
Fixed power compensation
Fixed equalization filter in EDFA guarantee even gain spectrum.
Dynamic channel power management
By using VMUX, WBU, WSU, WBM, gain spectrum slope efficiency adjustment
technology, dynamic gain optimization technology and optical performance monitoring
technology, these methods optimize power of all channels caused by nonlinear effect
and multi-stage amplifier gain un-flatness in large-capacity or long-distance system.
This mechanism can realize channel layer power management of OTM, FOADM and
ROADM. The network composed by these devices can be in end-to-end mode, link
mode and ring mode.
6.15 Performance Inspection
ZXONE 8000 has optical performance inspection unit. It is responsible for measuring
parameters of each optical path, e.g. optical power, central wavelength and OSNR. Also
relative data can be sent to the network management system. The network management
ZXONE 8000 Product Description
ZTE Confidential Proprietary 93
system supports two view manners, i.e. spectrum and data.
An optical forwarding part is capable of complete performance monitoring and consume
processing service. By inspecting different access signals hierarchically, it can
accurately locate the failure and determine fault type.
OTN signal: LOF, BIP-8, consume TTI, correctable error, uncorrectable frame,
OTUk-AIS, ODUk-AIS, ODUk-OCI, ODUk-LCK, PM-BIP8 and ODUk-PT
performance and alarm.
SDH signal: Monitor B1, B2 and J0 bytes.
GE signal: Monitor error packet number and error packet ratio, GFP performance
test.
All modules of active channel for ZXONE 8000 use large-scale and highly precise power
collection and monitoring technology. With less than 1dB error, it truly shows the system
performance.
6.16 Integrated Wavelength Monitoring
ZXONE 8000 provides two ways to keep stable wavelength. They are suitable for
different channel space systems.
100 GHz channel space
Automatic power control, temperature and inbuilt wavelength feedback mode are used.
This function is implied in OTU board.
50 GHz channel space
Inbuilt and additional wavelength feedback mode is used to enhance the stability and
precise of the wavelength.
Inbuilt wavelength feedback
Implemented by OTU, this service is same as 100GHz channel space service.
ZXONE 8000 Product Description
94 ZTE Confidential Proprietary
Additional wavelength feedback
The additional wavelength feedback of ZXONE 8000, i.e. wavelength monitoring
subsystem, uses integrated inspection and order adjustment mode to realize the control
of wavelength feedback.
This system is implemented by OWM, Multiplexer, OTU, SNP and network software
together. The service is as shown in Figure 6-10.
Figure 6-10 Wavelength Monitoring Subsystem
OWM board receives multiplexed optical signals from MON interface of amplifier. Inspect
wavelength deviation of all path wavelengths in multiplexed signals. If the deviation
exceeds restriction, SNP will be informed to send wavelength adjustment command to
related OTU board until the deviation disappears.
NM software implements parameter setting, initiation/forbidden services in the course of
wavelength adjustment. The command is sent to OWM board.
ZXONE 8000 Product Description
ZTE Confidential Proprietary 95
6.17 Communication and Monitoring
6.17.1 Optical Monitoring Channel
The monitoring and management information around different sites of ZXONE8000
system can be delivered and communicated via OSC. The wavelength of OSC is
1510nm, and the transmission speed is 100Mbit/s.
The delivery and communication of ECC data between NEs, business and transparent
user channel data and APS information are implemented via SOSC module and borne
on OSC. One piece of SOSC module can monitor four optical directions of information.
The major services are:
Encapsulate ECC data, APS data, transparent user channel data and public voice
data among network elements in 100M monitoring subsystem, then delivery them in
Ethernet data frame. Compared with fixed overhead byte, IP encapsulation gives
convenience to the extension of signaling message.
With 3 10/100BASE-T Ethernet electrical interfaces (actually physical interface is
provided by SEI board), it is capable of automatic switching service. SNP board and
NM accessed to100M monitoring subsystem delivers monitoring information in NE
via SOSC board and standby route.
On the front panel, there are 4 100BASE-FX Ethernet optical interfaces accessing
1510nm monitoring path to implement monitoring information delivery between NEs.
100BASE-FX is 100 Mbit/s optical interface.
Hardware-based L3 forwarding monitoring information capability is provided. L3
routing protocol is used to make network DCN-based interconnection easier. This
mechanism makes the signaling more adaptive to complicated networking
scenarios.
OSPF protocol and dynamic routing are used. With plug-and-play fiber, there’s no
need for manual configuration. Automatic route switchover can be implemented in
the course of network capacity extension, fiber and node breakdown.
ZXONE 8000 Product Description
96 ZTE Confidential Proprietary
SNP board reports NE and its subnet alarm and performance to NM. At the same time, it
receives the commands and configuration from NM to local NE and its subnet.
6.17.2 Electrical Supervisory Channel
The supervisory and management information of all ZXONE 8000 sites can be delivered
and communicated via ESC. ESC uses GCC overhead of G.709 to supervise path and
implement multiplexing and demultiplexing services. It is competent to sending NM,
public, protection and APR information.
6.18 Time/Clock Synchronization Service
ZXONE 8000 supports clock and time synchronization. It meets the requirements of the
3G base station for precise time synchronization.
Clock synchronization: It refers to the frequency synchronization. The frequencies
or phases of signals are closely related. Normally, the frequencies are the same
and the phase difference is constant for stable equipment operation.
Time synchronization: The frequencies and the phases of signals are the same.
Normally the time synchronization includes clock synchronization. The IEEE
1588V2 protocol is a widely-used time synchronization protocol.
The ZXONE 8000 clock synchronization function supports transmitting clock
synchronization signals among subracks and networks. It has the following features:
Supports the clock synchronization and the time synchronization to meet the
requirements for time synchronization accuracy.
The physical-layer synchronization mechanism extracts clock from the serial bit
stream in physical channel of transmission link to implement the frequency
synchronization.
The time synchronization complies with the IEEE 1588 V2 protocol. The ZXONE
8000 system provides an out-of-band time synchronization interface between
1pps+TOD and FE to implement the out-of-band time transmission.
ZXONE 8000 Product Description
ZTE Confidential Proprietary 97
Uses the Best Master Clock (BMC) algorithm to select a clock. The BMC algorithm
compares the descriptions of two or more clocks, and selects the better one. The
Ordinary Clock (OC), Boundary Clock (BC), and Transparent Clock (TC) are
supported.

6.18.1 Clock Synchronization
Three clocks that are transmitted in the OTN network are as follows: 2M BITS clock, SDH
service clock, and synchronous Ethernet clock. The OTN equipment supports two clock
transmission manners.
In-band clock transmission: The clock signals are transmitted through the service
channels.
Out-band clock transmission: The clock signals are transmitted through the OSC
optical supervision channel.
For a description of two clock transmission manners, refer to Table 6-18.
Table 6-18 Clock Transmission Manner
Clock

Manner
Implementation Solution
In-band clock transmission
Solution one: The CLK board and service board are used to extract, manage, and transmit the clock signals, normally, the 2M BITS clock or SDH clock signals.
If this solution is used, the clock configuration should be performed for the CLK board and service board on the NMS.
ZXONE 8000 Product Description
98 ZTE Confidential Proprietary
Solution two: The service board that supports the mapping of transparent frequency transmission or synchronous mapping is used to transmit GE and 10GE synchronous Ethernet clock signals. For example, the SOUT10G board supports 10GE-ODU2e synchronous mapping.
The clock information can be transmitted through the 10GE-ODU2e synchronous mapping. If this solution is used, there is no need to configure the clock on the NMS but a service channel should be established between service boards. The service mapping should support transparent frequency mapping or be the synchronous mapping.
Out-band clock transmission
The out-band clock transmission is implemented through the SOSCB board +TIS board configured on the OTN equipment.
If this solution is used, the clock configuration should be performed for the SOSCB board and the TIS board.
6.18.2 Time Synchronization
The OTN equipment supports transmitting IEEE 1588V2 time information through the
OSC optical supervision channel, that is, out-band time transmission.
The out-band time transmission is implemented through the SOSCB board and the TIS
board configured on the OTN equipment. For the NE that requires the input or output of
time information, you should configure the SOSCB board and the TIS board. For other
NEs, configure the SOSCB board.

6.19.3 PRBS Function
Boards on client sides have Pseudo Random Bit Sequence (PRBS) functions. The board
supporting the PRBS function works as a simple self-sending-and -self-receiving test
meter. Tests without meters can be implements, which is easy for fault location and
maintenance.
During commissioning debugs or fault location processes, you can replace service
signals of the clients with PRBS signals and determine whether the equipment or
transmission lines are normal by analyzing the PRBS signals looped back from the
remote end.
The principle of the PRBS test function is shown in Figure 6-11

Services are generated as per the following procedures:
Choose source and destination nodes
Choose bandwidth granularity and service level as per service type
According to restrictions, calculated proper service path
Enable all sites to build end-to-end service connection via RSVP-TE
signaling protocol
7.2.3 Protection and Restoration in Mesh Networking
As optical control plane, ZXUCP A200 is mainly used in mesh network to enhance
network resilience and service reliability
Mesh networking features in flexibility and extendibility. Compared with traditional WDM
network, there can be more service paths to make the network safer. This networking
mode makes maximum use of entire network resource.
In Mesh network, besides traditional ring/link protection solution like channel 1+1
protection and channel shared protection, reroute mechanism can also be used to
resume services in time.
7.2.4 SLA
Based upon SLA (Service Level Agreement), WASON network can provide different
levels of service as per different customers’ demands.

Failure of working path triggers protection switching within 50ms. Then
rerouting builds new protection path.
Failure of protection path triggers rerouting to build new protection path.
Failure of working path triggers protection switch again and rerouting builds
new protection path.
Gold: one-time service protection with mesh restoration
Initializing working and protection path.
Failure of working path triggers protection switching. However, rerouting
won’t be triggered until the protection path fails too.
Silver: only protection, but no mesh restoration
Copper: only mesh restoration.
Iron: Without protection and mesh restoration.

7.2.5 Network Traffic Balancing
After introducing intelligent feature, WASON network uses traffic engineering algorithm.
So that, it can adjusts network resource automatically. Entire network resources can be
distributed in balance automatically, which on one hand avoids congestion, on the other
hand enhances network security and operatability. At the same time, with multiple
constrains in path selection, it makes rational use of network resources.
WASON network can keep traffic of all routes in the network in balance, so that traffic
can be distributed evenly in the network. When there are many LSP between two nodes,
multiple LSPs may pass the same route. Network traffic balancing will try its best to avoid
this situation.
7.2.6 Multi-Level LSP Control
LSP referring to label switch path indicates the path that passed by intelligent services. In
WASON network, creating intelligent service equals to create LSP.
In traditional WDM network, wavelength is often considered as the granularity in path
selection. ZXUCP A200 can provide switching capability based upon ODUK granularity,
wavelength granularity, waveband granularity and fiber granularity. So that it can realize
multi-granularity hierarchical route. Multi-granularity link protection and restoration can
also be realized.

Receiver side note:
a The receiver shall be able to tolerate, without damage, continuous exposure to an optical input
signal having this average power level b Average receive power, each lane (min) is informative and not the principal indicator of signal
strength. A received power below this value cannot be compliant; however, a value above this does
not ensure compliance. c Receiver sensitivity (OMA), each lane (max) is informative. d Measured with conformance test signal at TP3 (see 87.8.11) for BER = 10–12. e Vertical eye closure penalty, stressed eye J2 Jitter, and stressed eye J9 Jitter are test conditions
for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
Transmit side note:
a Average launch power, each lane (min) is informative and not the principal indicator of signal
strength. A transmitter with launch power below this value cannot be compliant; however, a value
above this does not ensure compliance. b Even if the TDP < 0.8dB, the OMA (min) must exceed this value. c Transmitter reflectance is defined looking into the transmitter.
