Basic function

• 64 x ODU0/32 x ODU1/8 x ODU2<->8 x OTU2
• 8 x ODU2e<->8 x OTU2e
• Accesses four channels of OTU2/OTU2e signals from the ENQ2 board, and converts the signals into the standard DWDM wavelengths compliant with ITU-T G.694.1. The reverse process is similar.
• Integrates twelve channels of OTU2/OTU2e signals into one channel of optical signals.
• Unlike the TN54NPO2, the TN55NPO2S supports DCM-free transmission over short distance and the TN55NPO2L supports DCM-free transmission over long distance.

Cross-connect capabilities

Supports the cross-connection of 64 channels of ODU0 or 32 channels of ODU1 or eight channels of ODU2/ODU2e signals between the NPO2 board and the cross-connect board.

OTN function

• Supports the OTN frame format and overhead processing as defined in the ITU-T G.709.
• Supports PM function for ODU0.
• Supports PM and TCM functions for ODU1.
• Supports PM and TCM functions for ODU2.
• Supports SM function for OTU2.
• Supports PM and TCM non-intrusive monitoring for ODU1.

WDM specification

Supports ITU-T G.694.1-compliant DWDM specifications.

ESC function

Supported

PRBS test function

Supports the PRBS function on the WDM side.

LPT function

Not supported

FEC coding

Alarms and performance events monitoring

• Monitors 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.

Supports one channel of IEEE 1588v2 signals.

The TN55NPO2 board supports this feature only when ODU0 or ODU1 signals are cross-connected from the backplane.

Not supported

• Supports ODUk SNCP.
