Can optical ports connecting two switches work normally if their transmit/receive power is abnormal
When the power of optical ports connecting two switches is abnormal, either of the following situations occurs: -When the transmit/receive power of the optical ports is too high, optical modules on the ports may be damaged. In this case, connect an attenuator to the optical modules. -When the transmit/receive power of the optical ports is too low, error packets or packet loss may occur on the optical ports or the ports may be Down. In this case, you are advised to: -Check whether the fiber length between the two ports is within the maximum transmission range of the optical modules on the ports. -Check whether the fiber between the two ports is damaged. -Use optical modules with a longer transmission distance on the two ports. When connecting switches through optical ports, pay attention to the following points: -The optical modules used on both ends must have the same wavelength. -The receive power must be within the range required by the optical modules. -The transmission distance of an optical module is affected by the optical fibers connected to it. For example, when an OMXD30000 10GE SFP+ optical module uses OM1 multimode optical fibers, its transmission distance is 0.033 km. When this optical module uses OM3 multimode optical fibers, its transmission distance is 0.3 km. -The optical modules used on both ends must have the same transmission speed, and the interface configurations on both ends must comply with related protocols. -The type of optical modules used on the two ports is not restricted. For example, a port with an XFP optical module can communicate with a port with an SFP+ optical module, as along as they meet the preceding requirements.

Method used to check whether the transmit optical power of a TOG board is fixed
You can query for a change in the transmit optical power of the TOG board on the NMS and determine whether the transmit optical power is fixed based on the query results.

Differences between the RX1/TX1 and RX2/TX2 ports on the LDGF board and whether the two ports transmit services using the same channel
The LDG2 board has two client-side ports: RX1/TX1 and RX2/TX2. The two ports are GE ports and use the same channel to transmit services.
