Huawei OSN 9800 OTN 100G Tributary Board TNV3T401

Backplane capacity

The total bandwidth is 100 Gbit/s.

NOTE:

• The board supports backplane cross-connections of 1 ODU4/ODUflex signal from/to the cross-connect board.
• The board supports ODUflex when receiving 100GE (MAC Transparent Mapping) services on the client side.

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 TNV3T401 board uses a converter to receive 100GE services, 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:

Supports overhead processing defined by ITU-T G.709. The service mapping process complies with ITU-T G.709 and G.Sup43.

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 CFP2-100G(10x10G)-850nm(SR10)-MPO-MMF-0.1km, QSFP28-100G(4x25G)-850nm(SR4)-MPO-MMF-0.1km or QSFP28-100G(4x25G)-1271 to 1331nm(CLR4)-SMF-2km optical module, the board does not support client-side 1+1 protection.

ODUk SNCP

Supported

NOTE:

The board supports when k = 4, flex

Tributary SNCP

Supported

NOTE:

The board 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

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

LLDP

Not supported

Physical clock

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

IEEE 1588v2

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

ITU-T G.8275.1

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

ITU-T G.8273.2

Supported

NOTE:

• The board does not support ITU-T G.8273.2 when the system control board is U2CTU.
• Only the TNV3T401 board supports this function when receiving 100GE(GFP-F) services on the client side.

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

• When the 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

• 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.
