The client side of the TN53TSXL board is equipped with a fixed optical module, whose transmission distance is 2 km.

Whether client-side GE services support a transmission distance of 120 km
No. The client-side optical modules for GE services support a maximum transmission distance of 80 km. No optical module is available to support a transmission distance of 120 km.

Whether the client-side optical port of the peer OTU board does not send or receive optical signals if the client-side optical port of the local OTU board does not with ALS enabled
According to the ALS principle, if the local OTU board does not receive any optical signal on its client side, the peer OTU board will not emit light on its client side.

Whether the logical fibers between the client-side ports of OLP and OTU boards need to be created on the NMS
When port protection or 1+1 protection is configured in single-site mode, it is not mandatory to configure logical fibers. This is because boards and ports are specified in single-site configuration and there is no need to search for boards or ports based on logical fibers. Correct logical fibers created on the NMS provide references for configuration and check. Therefore, you are advised to correctly create logical fibers on the NMS.

Whether the two client-side optical ports of the TN12TDX board can be set to MAC transparent transmission
For the TN12TDX board, only its RX1/TX1 port can be set to MAC transparent transmission when the port mapping mode is set to MAC Transparent Mapping (10.7G). At this time point, the service type of the RX2/TX2 optical port must be set to None.
