TNF5ND2

Working modes of ND2 boards and their ports

ND2 boards do not support the setting of their working modes or their ports' working modes. They support the following service conversions:

• 16 x ODU0/8 x ODU1/2 x ODU2/4 x ODUflex <-> 2 x OTU2 (ODU is the abbreviated form of optical channel data unit, and OTU of optical channel transport unit.)
• 2 x ODU2e <-> 2 x OTU2e

Supports hybrid transmission of ODU0, ODU1, ODUflex, ODU2, and ODU2e signals.

Implements service grooming when working with cross-connect boards.

Supports the optical tunable transponder. Equipped with this module, the board can tune the optical signal output on the WDM side within the range of 80 wavelengths in C-band with the channel spacing of 50 GHz.

If the working temperature of the board exceeds the configured threshold and services are affected, the board will automatically reset the key chip to prevent damages to the board.

• Supports loopbacks on the WDM side.
• Supports loopbacks on ODU0 channels.
• Supports loopbacks on ODU1 channels.
• Supports loopbacks on ODUflex channels.

Supports the PRBS test function on the WDM side.

• Monitors bit interleaved parity 8 (BIP8) bytes (Bursty mode) to help locate line failures.
• Monitors parameters such as the bias current, operating temperature, and optical power of a laser.
• Monitors OTN alarms and performance events.

Adopts the ITU-T G.709-compliant frame format and overhead processing.

• Provides path monitoring (PM) for ODU2, ODUflex, ODU1, and ODU0.
• Provides section monitoring (SM) for OTU2.
• Provides tandem connection monitoring (TCM) for ODU2, ODU1, and ODU0.

• Supports ITU-T G.709-compliant forward error correction (FEC) encoding.
• Supports ITU-T G.975.1-compliant advanced forward error correction (AFEC)-2 encoding.
