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 traditional signals 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

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 noncoherent 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.

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 on the ROADM board.

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. Issue 01 (2015-12-31)

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.

Figure 6-8 Typical application

In Figure 6-8, service 1 is received through the client-side tributary board and is converted into an ODUk signal. Then the ODUk signal is cross-connected to the PID board by the crossconnect board and is finally converted into an OTUC2 optical signal before it is sent to the east direction on the WDM side. Service 2 is received by the west PID board. After the OTUC2-to-ODUk conversion is performed, the signal is cross-connected to the east PID board by the cross-connect board. After the ODUk-to-OTUC2 conversion, the signal is sent to the east direction on the WDM side.

Table 6-1 lists the network-level protection (OTN) schemes supported by the OptiX OSN 9800. Table 6-1 Network-level protection schemes (OTN) Protection Scheme

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 crossconnections 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 Product Features

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 to a 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 interdevice 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).

Table 6-4 lists the equipment-level redundancy supported by the OptiX OSN 9800 U64/U32/ U16. Table 6-4 Equipment-level redundancy Protection Scheme

Description

Power redundancy

Two PIU boards in hot backup mode supply power at the 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.

Fan redundancy

If a fan in a fan tray assembly fails, the system can remain operational for 96 consecutive hours in environments where temperatures range between 0°C to 40°C (32°F to 104°F).

XCS Board Redundancy

The cross-connect board uses the M:N backup policy. The working and protection cross-connect boards in a subrack connect to all other boards through the backplane bus to protect crossconnection services.

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


6 Product Features

Functi on

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 the required 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-FG), 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. Issue 01 (2015-12-31)

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 service OAM 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.

MPLS OAM

As the key bearer technology of the scalable next-generation network, 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.

7.1 Optical Doctor System Huawei OTN equipment supports the Optical Doctor (OD) system. The OD system provides for intelligent end-to-end, refined, and digital management of the optical layer on a WDM network. Through centralized configuration for optical-layer parameters, the OD system supports automatic monitoring, analysis, commissioning, and optimization of network performance.

Functions of the OD System The OD system supports online OSNR monitoring for 40G, 100G, 200G and 400G wavelengths, making the OSNR monitoring of 40G, 100G, 200G and 400G wavelengths as 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 400G wavelengths, 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 the operating 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 will consequently 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 reduce maintenance 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.

This board is mainly used to ensure that the Raman pump laser is properly started. It provides the following functions: l Locates fault points when the fiber connection detection results are abnormal. The fiber connection detection can be performed using the FCD button on the front panel of the TN12RAU1, TN12RAU2, TN11SRAU, TN51RPC, or TN12ST2 board in the fiber connection verification phase during hardware installation. l Checks fiber quality before deployment commissioning. l Locates fault points when the Raman laser cannot be turned on and a LASER_OPEN_FAIL alarm is reported. l Checks fiber health status at any time during network operations. l Analyzes whether a fiber quality issue occurs when the Raman gain is excessively low and an OA_LOW_GAIN alarm is reported. l Locates fault points when a fiber cut occurs and a MUT_LOS alarm is reported, or verifies fiber recovery status after a fiber cut is removed.

Networking Scenarios of the Line Fiber Quality Monitoring Function Based on the actual hardware configurations, the FD system can implement line fiber quality monitoring in two-fiber bidirectional and single-fiber bidirectional networking scenarios. Table 7-3 show the typical networking scenarios. NOTE

l The TN12ST2 board can be connected to an FIU, OLSP or OLSPA/OLSPB board. l The FIU board connected to a TN12ST2 board and its peer FIU board must be TN13FIU03, TN16FIU01, or TN11SFIU01. l The OLSP board connected to a TN12ST2 board and its peer OLSP board must be TN11OLSP01. The OLSP board is used in the two-fiber bidirectional transmission scenario. l The OLSPA/OLSPB board connected to the TN12ST2 board and the peer OLSPA/OLSPB board can be only TN11OLSPA01 or TN11OLSPB01, and TN11OLSPA and TN11OLSPB boards must be used in pairs. For example, if TN11OLSPA01 is used at one end of a fiber, TN11OLSPB01 must be used at the other end of the fiber. The OLSPA/OLSPB board is used in the single-fiber bidirectional transmission scenario. l On a short fiber span, a fixed optical attenuator (FOA) needs to be added so that the fiber insertion loss is greater than 15 dB, preventing a receiver overload issue. For a TN12ST2 board, the fixed optical attenuator (FOA) can be configured only on the RM1 or RM2 port of the board rather than the TMn or TXn port of other OSC boards.
