Access rate of a WDM-side port on the TMX board

18

The WDM-side signals of the TMX board are OTU2 signals, and the access rate is 10.71 Gbit/s.

Whether the TN53NQ2 board supports the WDM-side loopback
The TN53NQ2 board supports the WDM-side loopback only when ODU2 or ODU2e signals are received on the backplane side.

Maximum access rate of the TN52TOM board when the board works in tributary-line non-cascading mode and the dual-feeding and selective receiving function is enabled on the WDM side
In this scenario, three encapsulation paths are available for the TN52TOM board: Any->ODU0->ODU1->OTU1 OTU1->ODU1->Any->ODU0->ODU1->OTU1 OTU1/Any->ODU1->OTU1 The maximum access rates are 5 Gbit/s for all the three encapsulation paths.

Causes for reporting the LASER_MODULE_MISMATCH alarm when the WDM side of the LEX4 board is interconnected with the client side of the LBFS board
By default, a colored optical module is configured on the WDM side of the LEX4 board, and the board software will automatically create a logical colored optical module for this WDM-side optical module. During practical application, you need to create the correct logical optical module based on the actual type of physical optical module that is used.

Reason why the WDM-side signals of the TN11LOG board can be regenerated by the TN11LSXR board
WDM-side signals of the TN11LOG board can be regenerated by the TN11LSXR board because the FEC type of the TN11LSXR board is the same as that of the TN11LOG board.

Number of client-side ports on the TTX board
There are 10 physical ports on the client side of the TTX board and the port with the maximum number is RX10/TX10. On the NMS, numbers 1 and 2 have been assigned to IN/OUT ports on line boards. Ports on tributary boards are numbered from 3. TTX is a tributary board and therefore its ports are numbered from 3. In other words, logical port 3 on the NMS corresponds to the RX1/TX1 port.
