The Cisco 100BASE-FX Small Form-Factor Pluggable (SFP) Fast Ethernet Interface Converter is a hot-swappable device that plugs into a Gigabit Ethernet SFP port on Cisco Catalyst 3750 Series, 3560 Series, and 2970 Series switches. The Cisco SFP provides full-duplex 100-Mbps connectivity between switches over multimode fiber (MMF) infrastructures. It offers investment protection and an easy migration path for customers moving to Gigabit Ethernet connections in the future.

The Cisco GLC-GE-100FX= is a hot-swappable 100BASE-FX SFP with an LC duplex connector for 100 Mbps multimode-fiber links; it suits network teams connecting compatible Cisco Catalyst 3750, 3560, or 2970 switches over fiber.
Recommended For
- Network teams connecting compatible Cisco Catalyst 3750, 3560, or 2970 switches over existing multimode fiber when the link needs to run at 100 Mbps.
- Operators maintaining legacy 100BASE-FX multimode-fiber links who need an SFP for a compatible Cisco Gigabit Ethernet SFP port rather than a Fast Ethernet SFP port.
- Sites reusing multimode-fiber cabling for a short 100 Mbps switch-to-switch connection, with a fiber span within the module’s specified 2 km limit.
- Cisco network teams planning a staged upgrade: use a compatible 100BASE-FX link now and replace the optics later when moving that fiber connection to Gigabit Ethernet.
Real-World Use Scenarios
- Link two compatible Cisco switches over existing multimode fiber when a 100-Mbps connection is sufficient; the result is a fiber uplink without replacing the installed cable plant, within the optic’s stated 2-km limit.
- Connect a remote building’s legacy 100BASE-FX switch to a compatible Cisco switch over multimode fiber; this can preserve an existing 100-Mbps inter-building link rather than requiring a gigabit upgrade.
- Add a 100BASE-FX fiber connection to a supported Cisco switch that has a Gigabit Ethernet SFP port but needs to link to a 100-Mbps fiber endpoint; confirm the switch model and port support the GLC-GE-100FX before installation.
- Replace or install the SFP during switch maintenance when avoiding a reboot is useful; Cisco describes the module as hot-swappable, so the switch does not have to reboot for the module to be deployed.
