OTN functions
|
Port in 100G mode:Supports the OTU4 interface 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. Port in 200G mode:Supports the OTUC2 interface on the WDM side. OTUC2 layer: supports SM overhead processing. ODUC2 layer: supports PM and TCM 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.

|
|
|
WDM specification
|
Supports ITU-T G.694.1-compliant DWDM specifications.
|
|
|
|
|
Tunable wavelength function
|
The board supports tunable wavelengths of WDM-side optical signals in Super C band (1524 nm to 1573 nm).
|
|
|
|
|
PRBS test function
|
Supports the PRBS function on the WDM side.
|
|
|
|
|
Protection schemes
|
Supports ODUk SNCP. Supports tributary SNCP protection. Supports intra-board 1+1 protection (when working with the OLP or DCP board).
|
|
|
|
|
Latency measurement
|
The board supports latency measurement in the WDM-side optical port direction (upstream direction). When higher-order ODU4 cross-connections are created on the board, TCM latency measurement is supported for higher-order ODU4 channels.When lower-order ODUk cross-connections are created on the board, PM/TCM latency measurement is supported for higher-order ODU4 channels, and TCM latency measurement is supported for lower-order ODUk channels. The board supports PM and TCM latency measurement at the ODUCn layer.

|
Loopback
|
WDM-Side Loopback supported. Channel loopback:Port in 100G mode: ODUk (k = 0, 1, 2, 2e, 3, or flex) channel loopbacks Port in 200G mode or 400G mode: ODUk (k=0, 1, 2, 2e, 3, 4, flex) channel loopbacks.
