4 System ArchitectureThe OptiX OSN 9800 uses the L0 + L1 + L2 architecture. Wavelength multiplexing/demultiplexing and add/drop is implemented at Layer 0, ODUk/VC service grooming is

implemented at Layer 1 and ethernet/MPLS-TP switching is implemented at Layer 2.

l The equipment supports a tributary-line-separate architecture and a centralized cross-

connect unit to flexibly groom electrical-layer signals at different granularities.

l Universal line board is used to process electrical-layer signals, and the board can achieve

universal transmission and fine-grained grooming of OTN, VC and packet services.

l General service processing board provides the functions of both OTN tributary and line

boards, and each port on the board can be set to the tributary port or line port mode.

l The PIU power supply pools, 1+1 SCC/CTU and M:N XCS have a redundancy

protection design and ensure highly-reliable equipment operation.

6.1 Beyond 100G Transmission Application

By using the cutting-edge coherent detection technology, the OptiX OSN 9800 compensatesfor chromatic dispersion (CD) and polarization mode dispersion (PMD) without requiring

additional dispersion compensation modules (DCMs) in pure beyond 100G coherent

networks.

Line boards supporting the beyond 100 Gbit/s transmission solution: N401P, N402P, N501

and N601.

Figure 6-1 shows a typical application of the beyond 100 Gbit/s transmission solution.

Figure 6-1 Typical application of the beyond 100 Gbit/s transmission solution

The unique technical advantages of Huawei's coherent beyond 100 Gbit/s transmission

solution allow for high bandwidth utilization and long-haul transmission.

High Bandwidth Utilization

Huawei 100 Gbit/s transmission solution provides various service types and data rates and

supports the ODUflex technology to ensure high bandwidth utilization and reduce the

transmission cost per bit.

l Various service types and data rates are supported and carried over 200G transmission

channels.

l Optical-layer spectral width: 200G and 400G signals are compatible with traditionalsignals with 50 GHz spectral width. Compared with 100G signals, 200G and 400G

signals have improved the spectral efficiency by 100%. In addition, 200G and 400G

signals support flexible grid wavelengths and has higher spectrum utilization than the

systems using fixed spectrum.

l Electrical-layer grooming: ODUflex technology provides flexible bandwidth adjustment

and grooming.

Long-Haul Transmission

Using the 16QAM/QPSK technology, multi-carrier light source technology, and coherent

DSP/SDFEC algorithm, Huawei beyond 100 Gbit/s transmission solution achieves long-haultransmission without regeneration.





25


29/57

l 16QAM/QPSK

Together with the dual-carrier technology, 16QAM/QPSK reduces the baud rate of

optical signals without reducing the line rate, therefore reducing the spectral width of

optical signals and overcoming the bandwidth limitations of transmission devices.

l Coherent detection

This technology provides for a better OSNR and receiver sensitivity than those in a non-

coherent system.

l FEC technology

Huawei coherent transmission solutions support SDFEC schemes. Using advanced

algorithms, Huawei coherent solutions offer higher net coding gain and thus extends the

transmission distance.

6.2 100G Transmission Application

The OptiX OSN 9800 provides 40/80 x 100 Gbit/s transmission solution. By using the cutting

—edge coherent detection technology, the OptiX OSN 9800 compensates for chromatic

dispersion (CD) and polarization mode dispersion (PMD) without requiring additional

dispersion compensation modules (DCMs) in pure 100G coherent networks.

The boards supporting the 100 Gbit/s transmission solution: N401, N402, LSC, LTX.

Figure 6-2 shows a typical application of the 100 Gbit/s transmission solution.

Figure 6-2 Typical application of the 100 Gbit/s transmission solution

The unique technical advantages of Huawei's coherent 100 Gbit/s transmission solution allow

for ultra long-haul transmission, simplified network structure, high bandwidth utilization, and

Low Latency.

Ultra-Long-Haul Transmission

Huawei coherent transmission solution uses multiple technologies, such as ePDM+QPSK/

ePDM+BPSK modulation, coherent detection/second-generation coherent detection, FEC and

Hybrid OA, to achieve ultra-long-haul (ULH) transmission without electrical regeneration.

Simplified network architecture

Huawei coherent transmission solution simplifies network architecture and design, and

reduces network OPEX owing to its DCM-free design, high PMD tolerance, and simplified

ROADM architecture.

High Bandwidth Utilization

Huawei coherent transmission solution supports various service types and data rates.

Received services of different types are encapsulated into ODUk (k=0,1, 2, 2e, 3, 4,ODUflex) signals using OTN technology, and groomed and provisioned through central OTN

cross-connections. Bandwidth sharing, to the maximum extent, ensures high bandwidth

utilization and reduces the transmission cost per bit.

Figure 6-5 High Bandwidth Utilization of Coherent Transmission System

Low Latency

Due to low latency, Huawei coherent transmission equipment is especially suitable for

transport networks providing dedicated transport pipes for various business services, such as

financial, data center application, and cloud computing that allow for very low latency.

l Huawei advanced FEC technology provides optimal net coding gain while introducing

extremely low latency.

l Huawei coherent boards are equipped with DSP chips, which have superior performance

in CD and PMD compensation. Therefore, DCMs are no longer required in new 100G/

200G/400G networks, which not only reduces the network construction cost but also

eliminates the latency of the DCMs.

6.3 OTN + ROADM Application

The OTN + ROADM feature cross-connects a client service in any optical direction while

ensuring high bandwidth utilization.

Figure 6-6 illustrates how OTN and ROADM effectively transmit client services.

l A tributary board receives client services at any bit rate. After OTN mapping and ODUk

cross-connection are complete, the client signals are flexibly cross-connected on the

electrical layer and share bandwidth. A line board then outputs the signals over different

wavelengths.

l Along the optical cross-connections on the ROADM board, the signals over different

wavelengths can be transmitted in any optical direction.

l If the signals in an optical direction do not need to be locally terminated, they can be

directly transmitted to another optical direction through the optical cross-connections onthe ROADM board.





28


32/57

Figure 6-6 OTN + ROADM application

6.4 Flexible ROADM Application

In the beyond 100G system, flexible ROADM supports flexible grid bandwidth grooming in

addition to the 50 GHz and 100 GHz bandwidth grooming supported by traditional ROADM.

In other words, flexible ROADM supports flexible allocation and grooming of n x 12.5 GHz

bandwidth.

The beyond 100G system requires more flexible spectrum allocation for high-rate optical

signals and different bandwidths for signals in different modulation formats. The current

ROADM technology uses the fixed grid technique, in which the bandwidth is fixed to 50 or 100 GHz. Hence, this technique cannot provide flexible bandwidth allocation.

Flexible ROADM uses the flexible grid technique to allocate different bandwidths for

different signals, improving spectrum utilization and addressing the flexible signal grooming

requirements of future beyond 100G systems.

Flexible ROADM is compatible with existing networks and supports fixed 50 GHz and 100

GHz bandwidth defined in ITU-T Recommendations.

Figure 6-7 shows the networking of an example 2-degree flexible ROADM. Flexible grid

wavelengths are received, and the bandwidth of the wavelengths is not fixed to 50 or 100 GHz

but can be configured. Flexible ROADM allocates different bandwidths for different signals

and grooms the signals to the specified direction based on network configurations.

6.5 PID Application

Photonics integrated device (PID) helps to effectively eliminate bandwidth and O&M bottlenecks on a WAN, leveraging the features such as large capacity, high integration,

versatile multi-service access, small size, and environment-friendly design.

On a WAN, a 200G/400G aggregation ring based on PID boards (NP400 and NP400E) only is

recommended, eliminating commissioning while enabling quick service provision. At the

OTN aggregation layer, 13 to 20 aggregation rings can be deployed with two to four NEs in

each ring. A PID board(s) is used on each NE's line side. Build a 200G/400G network using

PID groups as required. Figure 6-8 shows the details.

NOTE

Configure protection for OTN equipment based on network needs to ensure high network reliability and

improve the disaster recovery capability of the OTN equipment.

Table 6-1 lists the network-level protection (OTN) schemes supported by the OptiX OSN

9800.

Table 6-1 Network-level protection schemes (OTN)

ProtectionScheme

Description

Client 1+1

protection

Protects services against faults on optical transponder units (OTUs) and

OCh fiber disconnections using the dual feeding and selective receiving

function of the OLP/DCP/QCP board.

Intra-board

1+1 protection

Protects OCh fibers using diverse routing and the dual feeding and

selective receiving function of OLP/DCP/QCP board.

LPT Detects and reports faults at the service access points and on intermediate

networks. It also helps data communication equipment, such as routers,

switch to the backup network in a timely manner. By doing so, normal

transmission of important services can be remained even when the link is

faulty.

Optical Line

Protection

It uses the dual fed and selective receiving function of the OLP board to

protect line fibers between adjacent stations by using diverse routing.

ODUk SNCP Protects services against line board faults and OCh fiber disconnections

using the dual feeding and selective receiving function of electrical-layer

cross-connections. The OptiX OSN 9800 supports ODUk SNCP protection.

Tributary

SNCP

Protects SDH/SONET or OTN services that a tributary board receives

using the dual feeding and selective receiving function of electrical-layer

cross-connections.

SW SNCP

Protection

In the case of the OptiX OSN 9800, SW SNCP uses intra-board cross-

connections on the TOM board to implement the dual fed and selective

receiving function. In this manner, SW SNCP protects the TOM OCh

fiber. The cross-connect granularity is GE or Any service.

6.6.2 Network Level Protection (Packet)

The Huawei WDM equipment provides a series of network-level Ethernet protection schemes

for packet-based transmissions, including such as pseudo-wire automatic protection switching

(PW APS), Tunnel APS, and link aggregation group (LAG).

The OptiX OSN 9800 provides various types of network level protection (packet), as listed in

Table 6-2.





32


36/57

Table 6-2 Network Level Protection (Packet)

Protection Description

ERPS Ethernet ring protection switching (ERPS) is applicable to ring physical

networks. ERPS protects Ethernet services on an Ethernet ring network.

LAG The LAG aggregates multiple physical links to form a logical link that is

at a higher rate. Link aggregation functions between adjacent equipment.

Hence, link aggregation is not related to the architecture of the entire

network. Link aggregation is also called port aggregation because each

link corresponds to a port on an Ethernet.

MC-LAG Multi-chassis link aggregation group (MC-LAG) allows links of multiple

NEs to be aggregated to form a link aggregation group (LAG). When a

link or an NE fails, MC-LAG automatically switches services to another

available link in the same LAG.

LMSP The Linear Multiplex Section Protection (LMSP) scheme is applicable toa point-to-point physical network, providing MS-layer protection for the

service between two points.

MC-LMSP The multi-chassis linear multiplex section protection (MC-LMSP)

supports that the working channel and protection channel of the LMSP

are configured on different devices to achieve protection for AC-side

links between devices.

MRPS Currently, transmission systems usually adopt ring topologies. MPLS-TP

ring protection switching (MRPS) implements rapid protection switching

in link/node failures and therefore ensures high service quality.

PW APS As network-level protection, PW APS uses a protection PW to protect the

working PW, and helps prevent service interruptions resulting from the

working PW failure.

MC-PW APS Multi-chassis PW APS (MC-PW APS) supports configuration of the

working and protection PWs on different devices to implement inter-

device PW protection.

Tunnel APS As a network protection scheme, tunnel APS uses a protection tunnel to

protect the working tunnel and prevent service interruptions in case of the

working tunnel failures. Tunnel APS is available in two types: Tunnel

APS 1:1 and 1+1.

6.6.3 Network Level Protection (OCS)

The Huawei WDM equipment supports a series of OCS-based network-level protection

schemes, including linear multiplex section protection (LMSP) and subnetwork connection

protection (SNCP).

The OptiX OSN 9800 provides various types of network level protection (OCS), as listed in

Table 6-3.





33

Table 6-3 Network Level Protection (OCS)

Protection Description

LMSP The Linear Multiplex Section Protection (LMSP) scheme is applicable to

a point-to-point physical network, providing MS-layer protection for theservice between two points.

SNCP The sub-network connection protection (SNCP) scheme protects the

service that is across subnets. The SNCP is based on the dual fed and

selective receiving mechanism. The subnet can be a chain, a ring, or a

more complex network.

6.6.4 OptiX OSN 9800 U64/U32/U16 Equipment-Level

RedundancyEquipment-level redundancy includes power redundancy, fan redundancy, cross-connect

board redundancy, and system control board redundancy.

time to one subrack. If one PIU board fails, the other board willcontinue to supply power to ensure that the subrack remains fully

functional.

operational for 96 consecutive hours in environments where

temperatures range between 0°C to 40°C (32°F to 104°F).

XCS Board

working and protection cross-connect boards in a subrack connect

to all other boards through the backplane bus to protect cross-

connection services.

universal platform subrack.

Table 6-5 Equipment-level redundancy

same time to one subrack. If one PIU board fails, the other

board will continue to supply power to ensure that the

subrack remains fully functional.

operational for 96 consecutive hours in environments where

temperatures range between 0°C to 40°C (32°F to 104°F).

System control board

redundancy

Two system control boards (SCCs) can be configured for 1+1

backup. The active and standby SCC boards in a subrack

l Inter-subrack communication

l Overhead management

6.7 Automatic Optical Power Management

The OptiX OSN 9800 provides multiple automatic optical power management functions, as

listed in Table 6-6.

Table 6-6 Automatic optical power management functions

Function

Description

ALS After the automatic laser shutdown (ALS) function is enabled on a tributary or

line board, the board shuts down the laser in the transmit direction when it

receives no optical signals from the upstream board. The board re-enables the

laser when it receives optical signals. This function prevents injuries caused by

lasers and prolongs the life of a laser by decreasing the working time of the

laser.





35


39/57

Function

Description

AGC The automatic gain control (AGC) function ensures that channel gain is not

affected when wavelengths are added or dropped or when there is optical power

fluctuation in the WDM system. This function guarantees normal service

running in the WDM system.

ALC Optical fiber aging, optical connector aging, multiple wavelengths added or

dropped simultaneously or other optical power changes are factors that may lead

to abnormal loss on the line. When this occurs, line loss is changed, the optical

signal-to-noise ratio (OSNR) of the system is degraded. To minimize such

influence, the automatic level control (ALC) function automatically adjusts the

output power of optical amplifiers in the link according to the line loss change.

When the line loss changes, the output power of it will remain unchanged.

APE The automatic power equilibrium (APE) function automatically detects and

adjusts the optical power along channels on WDM-side ports to ensure therequired channel optical power flatness. If the channel optical power varies and

flatness is not maintained to a specified requirement, the OSNR of the optical

transmission line will deteriorate, which will degrade and possibly interrupt the

communication.

IPA Optical amplifiers (OAs) output high optical power. If a fiber connecting to an

OA is cut, the OA keeps emitting light with high optical power if the laser on the

amplifier is not shut down. The intense light at the open fiber may cause injuries

to maintenance personnel during fiber maintenance. To prevent personal

injuries, the intelligent power adjustment (IPA) function shuts down lasers on

the affected OAs when a fiber cut occurs.

IPA of

Raman

system

The LINE optical port on the CRPC board outputs high-power pump light. To

prevent injuries associated with lasers, especially eye damage caused by laser

radiation, the IPA function shuts down lasers on Raman amplifiers when a line

fault occurs.

6.8 ASON Feature

Automatically switched optical network (ASON) is a new generation of the optical

transmission network. The ASON software developed by Huawei can be applied to the OptiX

OSN equipment to enable the evolution from a legacy transmission network to an ASON

network. Such evolution complies with the ITU and IETF ASON/GMPLS-related standards.

ASON enhances the network connection management and recovery capabilities by

introducing signaling to the transmission network and providing a control plane. It enables the

system to provide wavelength-level ASON services at the optical layer and ODUk level

ASON services at the electrical layer, and also achieves end-to-end service configuration and

service level agreement (SLA). As shown in the Figure 6-9, in a mesh network, a service

from the source node A to the sink node G can be transmitted along three paths: D1 (A-B-F-

G), D2 (A-D-G), and D3 (A-E-H-G). If a fault occurs between nodes A and B, or if the D1

path is unavailable, the service can be sent to the sink node along path D2 or D3 using ASON

techniques.

OAM(IEEE 802.3ah), focuses on point-to-point maintenance of

Ethernet links between two directly-connected devices in the last mile.

Ethernet port OAM is not applicable to services. Working with Ethernet

service OAM that applies to end-to-end Ethernet services, Ethernet port

OAM provides complete Ethernet OAM solutions.

Ethernet Service

OAM

Ethernet service OAM, also called connectivity fault management

(CFM), focuses on E2E maintenance of Ethernet links. Ethernet serviceOAM detects service information and manages individual network

segments that a service traverses by checking each maintenance

domain. Working with Ethernet port OAM, Ethernet service OAM

provides complete Ethernet OAM solutions.

Multiprotocol Label Switching (MPLS) can provide multiple services

with guaranteed QoS. Faults at the MPLS network layer, however,

cannot be rectified through the OAM mechanism of other layers.

Therefore, the MPLS network urgently requires OAM capabilities. This

document describes MPLS OAM that applies to the OAM of the MPLS

network.

convenient as that of 10G wavelengths. This greatly facilitates routine maintenance and

makes it easy to upgrade 10G networks to 40G/100G/400G networks.

Figure 7-1 Online OSNR monitoring using the OD system

The online OSNR monitoring provided by the OD system has the following features:

l Simple operations

The OSNR monitoring function is integrated into the U2000. It can be performed by

directly operating the U2000. The virtual meter provides graphical display of the

monitored OSNR information, without using other auxiliary devices or complex

operations.

l High detection precision

The detection precision is better than that of traditional 10G OSNR detection.

l Wide range of monitored wavelengths

Online OSNR monitoring is applicable to 10G, 40G, 100G, 200G and 400Gwavelengths, making the OSNR monitoring of all wavelengths at any type of site.

In addition, the OD system can be used to perform O&M of the optical layer on a WDM

network, as described below.

Figure 7-2 O&M of the optical layer on a WDM network

l Centralized configuration for network-wide monitoring

The OD system supports centralized configuration for optical-layer performance

monitoring parameters, greatly saving labor costs.

l Automatic monitoring of optical-layer performance

The OD system can automatically monitor network-wide optical-layer performance

without using any meters. It can automatically detect the channels with abnormal

performance.l Automatic optimization of optical-layer performance

Based on the performance data of each channel, the OD system can automatically adjust

the optical power of each channel so that the channel works in the optimal state.

l End-to-end (E2E) graphical display of optical-layer performance data

The OD system graphically displays link performance, facilitating status query and fault

isolation.

To sum up, the OD system can achieve OSNR monitoring of high-rate WDM networks, quick

monitoring deployment, monitoring, optimization, and analysis of E2E optical-layer

performance. It improves wavelength-level optical-layer O&M capabilities and provides

services along the lifecycle of WDM networks, simplifying the network O&M and saving theoperating expense (OPEX).

7.2 Fiber Doctor System

The fiber doctor (FD) system is used to monitor and manage line fibers in a network. By

precisely detecting the fiber connection status, the FD system helps maintenance personnel

analyze the quality of fiber connectors and splicing points, which facilitates quick fiber issue

diagnosis.

In a WDM system, fiber issues, such as fiber aging, fiber damages, fiber coiling, large-radius

bending, and large pulling stress, may cause large fiber attenuation and high BERs that willconsequently impair network operating.

In addition to fault diagnosis, traditional optical time domain reflectometers (OTDRs) can be

used to measure the fiber length, attenuation introduced in fiber transmission, and fiber

connector attenuation. OTDRs are therefore widely used in the fiber engineering and network

deployment phases.

Figure 7-3 Schematic diagram of the OTDR detection application

Fiber performance testing is classified into acceptance testing and maintenance testing based

on the test implementation phase. Acceptance testing is performed when links are offline.

With the wide application of fibers, maintenance testing has become a vital and usual part of

the process. Regularly performed maintenance testing helps detect the fiber performance in a

network in a timely manner. If traditional OTDRs are used to perform fiber performance

testing, the testing needs to be performed on site and services need to be interrupted.

Online fiber status detection methods that can achieve remote, online, accurate, and quick

fiber status detection are necessary to improve maintenance efficiency and reducemaintenance costs.

Line Fiber Quality Monitoring Function of the FD System

Using built-in probe lasers on the TN12RAU1, TN12RAU2, TN11SRAU, TN51RPC, or

TN12ST2 board to emit probe light, the FD system detects insertion loss changes and change

occurring positions in fibers based on the Rayleigh scattering and Fresnel reflection

principles. The FD system then reports the detected data to the NMS to implement the

following functions:

l Provide visualized OTDR meter-like GUIs on the NMS.

l Support remote monitoring of fiber quality.l Support quality detection for fibers within different length ranges based on the

monitoring mode and detection parameter settings.

l Save and compare historical detection results.

l View the length and attenuation of the specific fiber span on the entire network.

– NEs between sites A and F are interconnected with fibers and exchange information

over ESC/OSC channels using the HWECC protocol.

– Some NEs at certain site (such as, NEs at site B) are interconnected with network

cables (usually when optical and electrical NEs are separate), and exchange

information over Ethernet channels (provided by NM ports on the CTU boards)using the HWECC protocol.

– NEs at sites A and C are designated as gateway NEs (GNEs) and are connected to

an external data communication network (DCN) through a switch or router to

achieve communication with the NMS. All the other NEs are designated as non-

GNEs and communicate with the NMS through a GNE.

l Intra-NE communication: On each optical NE at sites A to F, the master and slave

subracks implement intra-NE communication.
