How to query the status of optical modules on Cisco switches?

First, we need to connect to the network, and then log in to the management platform of the Cisco switch. The user name and password are Cisco/cisco by default.

Step 2: In the privileged EXEC mode of the switch, use the following command to display the optical fiber port optical transceiver: show optical fiber port optical transceiver [interface interface id], interface interface id - (optional) Please specify the Ethernet port ID. (In this example, te1/0/3 uses the interface)

Finally, networking of Cisco switches requires DAC high-speed cables, AOC active optical cables, optical modules and jumpers. Here we will introduce the models of the following optical modules, which will help you understand the parameter information of optical modules and facilitate future purchase.
