Cisco 100Base-FX SFP for Multi-mode Networks

The Cisco GLC-FE-100FX= is a hot-swappable SFP transceiver built for 100 Mbps Fast Ethernet links over multi-mode optical fibre. It operates at a 1310nm wavelength through a single LC duplex port and is designed for network administrators extending or repairing legacy fibre runs in campus or metro environments. Buyers needing gigabit or single-mode reach should select a different module.

Thermals Power and Noise Profile

As a passive optical transceiver, the unit draws minimal power and generates no audible noise because it contains no moving parts or active cooling. Heat output is negligible within the standard operating envelope of compatible Cisco switches, so no special airflow provisions are required beyond normal chassis ventilation. The module supports the pay-as-you-populate model, allowing ports to be filled only as bandwidth demand grows.

Compatibility and Deployment Scope

The transceiver is validated for Catalyst 6500, 4500, 2960, ME 3400 and ME 2400 series platforms running the listed Cisco IOS or Catalyst OS releases. It is optically interoperable with any IEEE 802.3ah Draft 3.0 compliant 100BASE-X interface on the same link. No management software or licences are bundled; configuration is handled entirely through the host switch operating system.

Questions about this item

How do I install the GLC-FE-100FX= SFP into a Catalyst 6500 WS-X6148-FE-SFP slot, and what step is often missed?

Slide the transceiver into the SFP port until it clicks, then connect the LC duplex fibre; the step often missed is removing the dust plugs from both the module and the patch cable before seating the connectors.

What maintenance or replacement will the 1310 nm multi-mode SFP need over time?

Periodically inspect and clean the LC duplex ferrules with a lint-free wipe and isopropyl alcohol; replace the module if optical power drops below the receiver sensitivity after cleaning.

What limit appears first when the 100Base-FX link runs continuously at full 100 Mb/s?

The 100 Mb/s Fast Ethernet line rate is the hard ceiling; sustained traffic cannot exceed this bandwidth regardless of fibre length or switch backplane capacity.
