TNZ8NQ2-Huawei OSN 1800 4 Port 10G Line Service Processing Board

Basic function

Provides four line ports to convert a maximum of 32 channels of ODU0, 16 channels of ODU1, 4 channels of ODU2(e), or 32 channels of ODUflex signals to 1 channel of OTU2(e).

For details about the service mapping path, see Application.

Backplane capacity

The total backplane bandwidth is 40 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

NOTE:

Boards adopting different error correction encoding modes cannot interoperate with each other.

OTN overhead protocol

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

OTN overhead

• WDM-side OTU2 layer: supports SM overhead processing.
• ODUk (k=0, 1, 2, flex) layer: supports PM overhead processing.
• ODUk (k=0, 1, 2) layer: supports TCM overhead processing.

Intra-board 1+1 protection

Supported

ODUk SNCP

Supported

NOTE:

Support when k = 0, 1, 2, or flex

Tributary SNCP

Supported

Electrical-layer ASON

Supported

NOTE:

Only supported when the TNZ6UXCMS/TNZ5UXCMS/TNZ8XCH board is used.

Overtemperature protection

Supported. If the temperature of a board exceeds the upper threshold and services are affected, the board will automatically reset the key chips to prevent a board damage.

Physical clock

Supported (ODU0, ODU1, ODUflex)

NOTE:

When the ODUk 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 ODUk cross-connections are configured.

IEEE 1588v2

Not supported

Outband DCN

Supports communication over ESCs.

NOTE:

For details about the DCN types supported by the board, see "Feature Description - Outband DCN - Introduction to DCN - DCN Communication Channel - Comparison Between OSC and ESC".

Test frame

Not supported

PRBS

Supports the PRBS function on the WDM side.

Latency measurement

Supported

Channel loopback

Supports channel inloops and outloops.

Port loopback

Supports WDM-side inloops and outloops. (This function has no impact on overheads and the PRBS function.)

Alarm and performance event monitoring

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