Each port on the board support a mix of ODU0, ODU1, ODU3, ODU2, ODU2e, and ODUflex signals.

Supports backplane cross-connections of 160 ODU0, 80 ODU1, 20 ODU2, 20 ODU2e, 4 ODU3, 2 ODU4, or 160 ODUflex signals from/to the cross-connect board.

• Supports OTU4 on the WDM side.
• Supports the OTN frame format and overhead processing defined by ITU-T G.709.
• OTU4 layer: supports SM overhead processing.
• ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads.

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

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

TNU5N402 supports tunable wavelength optical modules that provide for 96 wavelengths tunable in the extended C band with 50 GHz channel spacing.

• TNU1N402: Supports SDFEC on the WDM side.
• TNU2N402: Supports SDFEC2 on the WDM side.
• TNU3N402: Supports SDFEC2 on the WDM side.
• TNU5N402:
  • When OTU4-4 x 28G -10km-CFP modules are used: FEC
  • When other modules are used: SDFEC2, HFEC PLUS
• TNV1N402: Supports FEC on the WDM side.
• TNV2N402: Supports HFEC on the WDM side.

• 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.

The WDM-side signals of an N402 board can be regenerated using the N401, N402, LTX, or NS4 board of the same type. For example,

• The type of the TNU1N402T11 board is T11, and the WDM-side signals of the TNU1N402T11 board can be regenerated using the N401, N402, LTX, or NS4 board of the T11 type, such as TNU1N401T11, TNU1N402T11, TN54NS4T11, TN56NS4T11, TN11LTXT11, and TN12LTXT11.

• TNU3N402/TNU5N402: Supported
• TNU2N402: Supported by some board types.
• Other N402 boards: Not supported

• Supports ODUk SNCP.
• Supports tributary SNCP protection.
• Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board).
• Port-Level M:N Protection: Only the TNU3N402/TNU5N402 board supported. The TNU3N402 boards support port-level M:N protection only in VER.C and later versions.
