Product Overview
The Cisco GLC-FE-100EX and GLC-FE-100LX are Fast Ethernet SFP transceivers designed to provide 100BASE-EX and 100BASE-LX connectivity, respectively, over single-mode fiber (SMF). These SFPs offer long-range fiber transmission at 1310 nm, with the EX version supporting up to 40 km and the LX version up to 10 km. They are ideal for metro access, enterprise backhaul, or long-distance campus deployments requiring reliable and interference-resistant Ethernet connections.
