Run the display transceiver interface interface-type interface-number verbose command to view optical module information. Whether you are creating a 100-Gbps or 400-Gbps, small form-factor pluggable (SFP) module, SFP+ transceiver, XFP module, CFP, X2/XENPAK module. If you know the model or type of an optical module, you can view the section "Pluggable Modules for Interfaces" in the Hardware Description to look up parameters of the optical module, including the center wavelength, transmission distance, fiber types supported, receive optical power, and transmit. For example, when you run the display transceiver interface interface-type interface-number verbose command, the following information is displayed. When the optical module on an interface is faulty, you can run the display commands to view information about the optical module.
