Network Media Converter Cisco GLC-FE-100FX

The Cisco GLC-FE-100FX is a 100BASE-X SFP module designed for multimode fiber (MMF) links up to 2000 m. It operates at a wavelength of 1310 nm with a power budget of -31 dB and is intended for use as a network media converter or fiber interface in LAN environments. The module is hot-swappable and interoperable with compatible 100BASE-X Ethernet interfaces.

Advantages

The module supports hot-swapping so the switch or router does not need to reboot when installing or replacing the SFP. It follows a pay-as-you-populate model and is optically interoperable with corresponding 100BASE-X interfaces. The transceiver is interchangeable with other 100BASE-X SFPs on the same line card and supports Cisco quality identification to allow the device to detect Cisco-qualified modules.

Suitable for

• Extending LAN connections over multimode fiber up to 2000 m
• Replacing or upgrading fiber interfaces on compatible switches and routers
• Small and medium enterprise network segments requiring 100BASE-FX links

Key specifications

• Form factor: SFP (100BASE-X)
• Maximum transfer distance: 2000 m
• Wavelength: 1310 nm
• Power budget: −31 dB
• Compatible fiber type: Multimode fiber (MMF)
• Manufacturer part number (MPN): GLC-FE-100FX

How to use

Insert the Cisco GLC-FE-100FX SFP into a compatible SFP slot on a switch or router while the device is powered on; the module supports hot-swapping so a reboot is not required. Connect a multimode fiber patch cord to the SFP transceiver and verify link status on the device. Configure the network interface as needed in the switch or router management interface to match 100BASE-FX settings.

Recommendations

Use multimode fiber patch cords rated for 1310 nm and ensure connectors and patch panels are clean. Confirm compatibility with the host device and use Cisco-qualified modules where device features depend on Cisco quality identification.
