Typical Troubleshooting Cases of Optical Module
Use an optical power meter to measure the receive power of the port. Form a loop on the port using an optical fiber, and check whether the port can go Up (if optical modules with a long transmission

Execute the command "combo enable fiber" in interface mode to switch to the optical interface; on the contrary, "undo combo enable fiber" switches to the default electrical interface state. For details about the optical modules supported by optical ports on switches, see "Appearance and Structure" of a specific switch model in the Hardware Description. During use, reading optical module information helps understand its real-time operating status, enabling faster troubleshooting of link abnormalities. Solution: To solve this problem, you can follow these steps: Check if the fiber and optical modules are compatible. The Combo interface, also known as the optical-electrical multiplexing interface, consists of two Ethernet ports (one optical and one electrical) on the device panel, and there is only one forwarding interface inside the device.
