Home / How to read the label on an optical module
Generally, the label of an optical module provides the following information: manufacturer, serial number, speed, center wavelength, mode (single-mode/multimode), and transmission distance. To determine if your SFP (Small Form-factor Pluggable) module is single mode or multimode, you can look for specific markings or labels on the module itself. Typically, single mode SFP modules are labeled as "SM" or "single mode," while multimode modules may be labeled as "MM" or "multimode. During use, reading optical module information helps understand its real-time operating status, enabling faster troubleshooting of link abnormalities.
