Huawei OSN 9800 OTN 100G Tributary Board TNV8T402

Function and Feature

Description

Backplane capacity

The total bandwidth is 200 Gbit/s.

NOTE:

Supports backplane cross-connections of two ODU4/ODU3/ODUflex signals from/to the cross-connect board.

Client-side service type

Flexible Ethernet service (FlexE) service:

1. 100G FlexE unaware: The rate is 103.125 Gbit/s

OTN service:

1. OTU4: The rate is 111.81Gbit/s

Ethernet service:

1. 40GE: The rate is 41.25 Gbit/s
2. 100GE: The rate is 103.125Gbit/s

NOTE:

The client-side port type is QSFP4*28G by default, and the access service type can be set to 100GE or OTU4. If other client-side services need to be transmitted or received, the port type must be changed.

Service mapping mode

1. 100GE service: Supports Bit Transparent Mapping ODU4, MAC Transparent Mapping ODU4, and MAC Transparent Mapping ODUFlex.
2. 40GE service: 40GE (TTT+GMP), 40GE(MAC transparent mapping).

FEC coding

1. Supports ITU-T G.709-compliant forward error correction (FEC) when the client-side service type is OTU4.
2. When the client-side service type is 100GE/FlexE, only RS_FEC coding is supported.

OTN overhead

1. ODUflex layer: supports PM overhead processing.
2. ODU3 layer: supports PM overhead processing.
3. ODU4 layer: When the client-side service type is 100GE, supports PM overhead processing.
4. ODU4 layer: When the client-side service type is OTU4, supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads.
5. OTU4 layer: supports SM overhead processing.

Maximum frame length for a port

1518 to 9600 Bytes, supports a jumbo frame with a maximum length of 9600 bytes.

LPT

Not supported

Client 1+1 protection

Supported

NOTE:

When FlexE services are received on the client side: The line board that works with the V8T402 board does not support intra-board 1+1 protection. The board does not support client 1+1 protection.

Does not support client 1+1 protection when an MPO optical module is used on the client side to receive services.

ODUk SNCP

Supported

NOTE:

1. The board supports ODUk SNCP when k = 3, 4, flex
2. When FlexE services are received on the client side: ODUk SNCP protection groups in a FlexE group must be bound to implement unified switching of multiple ODUk SNCP protection groups.

Tributary SNCP

Supported

Electrical-layer ASON

Supported

L1 service encryption

Supported

NOTE:

Client-side port encryption is supported in the case of 40GE/100GE services.

ClientLP port encryption is supported in the case of FlexE services.

ALS

Supported on the client side when non-OTN services are received.

LLDP

Supported on the client side when ethernet services are received.

NOTE:

1. LLDP is not supported in the case of FlexE services.
2. When the service mapping mode is MAC transparent mapping, the LLDP mode of the port is the Receive mode by default. In this case, LLDP packets are not transparently transmitted.

Physical clock

1. Bit Transparent Mapping ODU4: Supports synchronous Ethernet transparent transmission
2. Mac Transparent Mapping ODU4//ODUflex: Supports synchronous Ethernet processing

IEEE 1588v2

Supports this function when receiving 100GE(MAC transparent mapping) services on the client side.

ITU-T G.8275.1

Supports this function when receiving 100GE(MAC transparent mapping) services on the client side.

ITU-T G.8273.2

Supported

NOTE:

1. The board does not support ITU-T G.8273.2 when the system control board is U2CTU.
2. When the client-side service type is 100GE(GFP-F), the board supports ITU-T G.8273.2.

Outband DCN

Supported communication over ESCs when the client-side service type is OTU4.

Test frame

Supports test frames when receiving 40GE/100GE services on the client side.

NOTE:

For Ethernet test frames, only one interface can be used to send them at a time.

PRBS

Supported

NOTE:

The PRBS function in the optical port direction is supported only when the client-side service type is OTU4 .

Latency measurement

1. When non-OTN services are received on the client side of the board, the PM section latency measurement is supported in the backplane direction (upstream direction).
2. When OTN services are received on the client side of the board, the TCM section latency measurement is supported in the optical port direction (downstream direction).

Channel loopback

Not supported

Port loopback

1. Supports inloops and outloops on the client side.
2. Supports ODUk inloops and ODUk outloops on the client side.

NOTE:

The board supports ODUk inloop and ODUk outloop only when non-OTN services are received, the port working mode is non-convergence, and bidirectional cross-connections are configured.

When the service type is set to None, Inloop, Outloop, and ODUk Outloop are not supported.

When non-OTN services are received, the PRBS in the backplane direction can be used only with ODUk loopback.

FlexE group loopback

1. Supports FlexE group inloop.
2. Supports FlexE group outloop.

Alarm and performance event monitoring

1. Monitors BIP8 bytes to help locate line failures.
2. Monitors OTN alarms and performance events.
3. Monitors parameters such as the bias current, temperature, and optical power of the laser.
4. Provides remote monitoring (RMON) of the Ethernet service.
