Cisco Rugged 100BaseFX LC Multi-Mode SFP Transceiver Module

The Cisco GLC-FE-100FX-RGD is a small form factor pluggable transceiver that adds a 100BaseFX fiber link to any Cisco switch or router with an available SFP slot. It lets network teams extend Fast Ethernet connectivity over multimode fiber while keeping the hardware footprint minimal.

Operating at 1310 nm, the module carries 100 Mbps traffic over LC-terminated fiber runs up to two kilometers. This range is well suited for connecting buildings on a campus, wiring closets in a warehouse, or control panels scattered across a factory floor where copper cabling cannot cover the distance or meet interference requirements.

The design is both compact and hot swappable, so you can insert or replace the unit without shutting down the interface. That flexibility supports a pay-as-you-populate approach: purchase only the transceivers you need today, then scale as new fiber drops come online.

The module integrates seamlessly with other 100BaseX SFPs, preserving investments in existing optics and simplifying spare-parts management. Field technicians, industrial automation engineers, and campus network administrators will appreciate the identical Cisco command-line experience and straightforward diagnostics that come with every Cisco optic.

Use cases range from linking traffic cameras to a roadside switch, to feeding environmental sensors in a utility substation, to creating a short-haul fiber uplink between edge devices in a school or hospital. Wherever reliable Fast Ethernet over multimode fiber is required, this transceiver provides a proven, Cisco-qualified solution.
