Huawei OptiX OSN 9800 16 Port 25 Gbit/s Universal Line Service Processing Board TNU6U316

Basic function

Supports conversion between a maximum of 320 ODU0, 160 ODU1, 32 ODU2(e), or 320 ODUflex signals and OTU25v signals.

Backplane capacity

• The maximum capacity is 400 Gbit/s when the U32 enhanced subrack works in 2:5 mode (using U1UCXCS/U3UCXCS/U4UCXCS), the U64 enhanced subrack (using U1UCXCS/U3UCXCS/U4UCXCS), or the M24 subrack works in 1:3 mode.
• The maximum capacity is 200 Gbit/s when the U32 enhanced subrack works in 2:2 mode, the U32/U64 enhanced subrack (using U3UXCS), the U32/U64 standard subrack, or the M24 subrack works in 1:1 mode.

NOTE:

When the backplane bandwidth is 200 Gbit/s, only the first eight ports IN1/OUT1 to IN8/OUT8 can be used as line ports. In this case, the last eight ports IN9/OUT9 to IN16/OUT16 support bidirectional regeneration.

WDM specification

Supports the DWDM specifications.

Tunable wavelength

Supports tunable wavelength optical modules that provide for 96 wavelengths tunable in the extended C band with 50 GHz channel spacing.

FEC coding

RS_FEC

Line modulation format

NRZ

OTN overhead protocol

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

OTN overhead

• OTU25v layer: supports SM overhead processing.
• ODU25v layer: supports PM and TCM overhead processing.
• ODUk (k=0, 1, 2, 2e, flex) layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads.

Intra-board 1+1 protection

Not Supported

ODUk SNCP

Supported

NOTE:

ODUk SNCP protection is not supported when packet services are cross-connected from the backplane.

Tributary SNCP

Supported

Electrical-layer ASON

Supported

Optical-layer ASON

Not 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

Supported

NOTE:

Only ports 1 to 15 support IEEE 1588v2.

ITU-T G.8275.1

Supported

NOTE:

Only ports 1 to 15 support ITU-T G.8275.1.

ITU-T G.8273.2

Supported

NOTE:

• When the matching system control board is U2CTU, the board does not support ITU-T G.8273.2.
• Only ports 1 to 15 support ITU-T G.8273.2.

Outband DCN

Supports communication over ESCs.

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

Channel loopback

Supports ODUk (k=0, 1, 2, 2e, flex) channel inloops and outloops.

Port loopback

Supports WDM-side inloops and outloops.

Alarm and performance event monitoring

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