The GLC-FE-100FX is a Cisco 100BASE-FX Small Form-Factor Pluggable (SFP) transceiver module. It’s designed for Fast Ethernet (100 Mbps) connections over multimode fiber optic cable. This SFP module uses an LC connector and operates at a wavelength of 1310nm. It’s commonly used to extend network connections over longer distances than copper cabling allows, typically within building or campus environments.
