How to view optical port parameters on a switch

Execute the following command to view detailed interface and optical module status: show interface Execute the following command to view detailed interface and optical module status: show interface When optical modules operate on a switch, it is usually necessary to read the module's internal information to understand its working status—such as connection status and real-time metrics like optical power and temperature. Additionally, identifying module information helps detect coding. This article provides instructions on how to view the Optical Module Status on your switch through the Command Line Interface (CLI). This guide provides complete, step-by-step CLI commands to view module type, DOM/DDM diagnostic data. 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. Digital Optical Monitoring (DOM) is a feature that allows for the real-time monitoring of various physical and operational parameters of fiber optic transceivers, such as transmit power, receive power, temperature, laser bias current, and voltage. By checking module health, compatibility, and digital diagnostics, you can quickly confirm correct installation, detect optical problems, and maintain accurate hardware.
