Cisco GLC-GE-100FX 100BASE-X SFP Pluggable Transceiver Module

The Cisco GLC-GE-100FX is a Small Form-Factor Pluggable transceiver that delivers reliable 100 Mbps Fast Ethernet over multimode fiber. It slides directly into the SFP slot on Cisco Catalyst 3750, 3560, and 2970 switches, making it a simple way to extend fiber links without replacing existing hardware.

Installation is straightforward: insert the module, connect the LC duplex fiber cable, and the switch immediately recognizes the link. Because it is hot swappable, you can add or replace it while the switch stays online, which keeps critical services running and limits maintenance windows.

Full-duplex capability doubles the effective bandwidth to 200 Mbps, a benefit for departments that move large files, back up data, or stream video across the network. The module follows the IEEE 802.3z standard, so it integrates smoothly with other compliant equipment and safeguards your investment as you expand the fiber infrastructure.

This transceiver fits well in campus networks, branch offices, and industrial control rooms where copper cabling is either impractical or prone to interference. Network administrators who need a cost-efficient fiber link for Fast Ethernet will appreciate its dependable performance and the familiar Cisco management experience.
