Huawei OptiX OSN 9800 1 Port 100G OTN Tributary Service Processing Board TNG1T401

Backplane capacity

The total bandwidth is 100 Gbit/s.

NOTE:

Supports backplane cross-connections of 1 ODU4/ODUflex signal from/to the cross-connect board.

Client-side service type

• 100GE: Ethernet service at a rate of 103.125 Gbit/s
• OTU4: OTN service at a rate of 111.81 Gbit/s

Service mapping mode

100GE service: Supports Bit Transparent Mapping ODU4, MAC Transparent Mapping ODU4, and MAC Transparent Mapping ODUFlex.

FEC coding

• Supports ITU-T G.709-compliant forward error correction (FEC) on the client side when the client-side service type is OTU4.
• When the client-side service type is 100GE, only RSFEC coding is supported.

OTN overhead

• ODUflex layer: supports PM overhead processing.
• ODU4 layer: When the client-side service type is 100GE, supports PM overhead processing.
• 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.
• OTU4 layer: supports SM overhead processing.

NOTE:

The mapping process complies with ITU-T G.7041 and ITU-T G.709. The board adopt the ITU-T G.709-compliant frame format and 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 the client-side uses QSFP28-100G(4x25G)-850nm(SR4)-MPO-MMF-0.1km optical module, the TNG1T401 board does not support client-side 1+1 protection.

ODUk SNCP

Supported

Tributary SNCP

Supported

NOTE:

Supports the tributary SNCP protection, only when the client side service type is OTU4.

Electrical-layer ASON

Supported

L1 service encryption

Supported

NOTE:

When receiving OTU4 services on the client side, the board does not support the encryption.

ALS

Supported on the client side when 100GE services are received.

LLDP

When the client-side service type is 100GE, the board supports the LLDP function.

NOTE:

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

• Bit Transparent Mapping ODU4: Supports synchronous Ethernet transparent transmission
• Mac Transparent Mapping ODU4: Supports synchronous Ethernet processing

IEEE 1588v2

When the client-side service type is 100GE(MAC transparent mapping), the board supports IEEE 1588v2.

ITU-T G.8275.1

Supports this function when receiving100GE(MAC transparent mapping) services on the client side.

ITU-T G.8273.2

Supported

Outband DCN

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

Test frame

When the client-side service type is 100GE, the board supports test frame.

PRBS

Supported

NOTE:

When a TNG1T401 board receives OTU4 services, the PRBS test function is supported in both the optical port direction and the backplane direction. When the board receives 100GE services, the PRBS test function is supported only in the backplane direction.

Latency measurement

Supported

NOTE:

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). 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

• Supports inloops and outloops on the client side.
• 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.

Alarm and performance event monitoring

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