Huawei OptiX OSN 9800 20 Port 10G Line Service Processing Board TNS2N220

Backplane capacity

The total backplane bandwidth is 200 Gbit/s.

WDM specification

Supports the DWDM specifications.

Tunable wavelength

Supports tunable wavelength optical modules that provide for 80 wavelengths tunable in the C band with 50 GHz channel spacing.

FEC coding

FEC, AFEC-2

Line modulation format

NRZ

OTN overhead protocol

Supports the OTN frame format and overhead processing defined by ITU-T G.709.

OTN overhead

• WDM-side OTU1/OTU2/OTU2e layer: supports SM overhead processing.
• ODUk (k=0, 1, 2, flex) layer: supports PM and TCM overhead processing.
• ODUk (k=0, 1, 2, flex) layer: supports non-intrusive monitoring of PM and TCM overheads.
• OSUflex layer: supports PM and TCM overhead processing.
• OSUflex layer: supports non-intrusive monitoring of PM and TCM overheads.

OSU

Supported

NOTE:

The OSU function requires a license.

Intra-board 1+1 protection

Supported

NOTE:

Supports intra-board 1+1 protection when working with optical protection boards.

ODUk SNCP

Supported

OSUflex SNCP

Supported

NOTE:

• When working with a TNG1CXP board, the TNU2CTU/TNS2N220 board supports a maximum of 1024 OSUflex SNCP protection groups.
• When working with a TNU4CTU/TNU5CTU/TNG3CXP/TNG4CXP board, the TNS2N220 board supports a maximum of 2000 OSUflex SNCP protection groups.

Tributary SNCP

Supported

Electrical-layer ASON

Supported

Optical-layer ASON

Supported

Physical clock

Supported

NOTE:

When the ODU cross-connect granularity of an OTN line port is set to the maximum granularity supported by the port, physical clock synchronization is not supported. The physical clock can be used only after lower-order ODU cross-connections are configured.

IEEE 1588v2

Not supported

Outband DCN

Supports ESC communication.

Test frame

Not supported

PRBS

Supports the PRBS function on the WDM side.

Latency measurement

The board supports latency measurement in the WDM-side optical port direction (upstream direction).

• When higher-order ODU4 cross-connections are created on the board, TCM section latency measurement is supported for higher-order ODU4 channels. When lower-order ODUk cross-connections are created on the board, PM/TCM section latency measurement is supported for higher-order ODU4 channels, and TCM section latency measurement is supported for lower-order ODUk channels.
• The board supports PM and TCM latency measurement for the OSUflex channels.

NOTE:

In the OSU application scenario, unidirectional delay measurement is not supported, and only bidirectional delay measurement is supported.

Channel loopback

• ODUk (k=0, 1, flex) channel loopbacks
• OSUflex Channel Loopback

NOTE:

The board supports a maximum of eight OSUflex channel loopbacks.

Port loopback

Supports WDM Side Loopback

Alarm and performance event monitoring

• Supports the monitoring of BIP8 bytes (Bursty mode) to help locate line faults.
• Monitors parameters such as the bias current, temperature, and optical power of the laser.
• Monitors OTN alarms and performance events.
