On the WDM side, only the IN1/OUT1 optical ports can be used if no protection is configured for the ELOM (COMP) board. ELOM (STND) and F2ELOM (STND) boards support the following board and port working modes: - 1*AP8 general mode, the board supports the following port working modes:
- ODU0 non-convergence mode: 8 x Any (125 Mbit/s to 1.25 Gbit/s) <-> 2 x OTU2 (ODU is the abbreviated form of optical channel data unit, and OTU of optical channel transport unit.)
