Cisco GLC-GE-100FX= — 100FX SFP for Gigabit Ports
100 MbpsGE SFP portsMultimode 2 kmDual LC
The Cisco GLC-GE-100FX= is a 100BASE-FX SFP module designed to run in the Gigabit Ethernet SFP ports of Cisco switches and routers, carrying 100 Mbps over multimode fibre up to 2 km at 1300 nm. It lets a modern Gigabit switch connect to older 100 Mbps fibre equipment, such as legacy switches, industrial controllers or building systems. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short LC patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
Compatibility — check before buying:
It works only in Gigabit Ethernet SFP ports of Cisco devices. For Fast Ethernet or dual-rate FE/GE ports Cisco makes the GLC-FE-100FX instead. Cisco states it is not compatible with media converters, NICs or third-party products. It runs at 100 Mbps only, and the far end must be 100BASE-FX on multimode fibre — not a 1000BASE-SX module. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your switch model and the cable run and we check it before you order.
Best For
✓ Connecting legacy 100 Mbps fibre equipment
✓ Gigabit Cisco switches talking to old FX gear
✓ Building management and industrial links
✓ Multimode runs up to 2 km
✓ Migrating from old FE switches
✓ Replacing a failed GE-100FX module
Key Features
100FX in a Gigabit port
Lets a Gigabit SFP port talk to 100BASE-FX equipment, so an old fibre device can stay in service after the switch is upgraded.
2 km on multimode
At 1300 nm, 100BASE-FX reaches up to 2 km over multimode fibre — much further than Gigabit SX optics on the same fibre.
Multimode fibre, short reach
Built for the short runs inside a building or data room over OM-grade multimode fibre. Reach depends on the fibre grade, so check what is actually in your walls before you plan a link.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.

Frequently Asked Questions
Singular Expert Insight
We sell the GLC-GE-100FX= when a customer upgrades to a Gigabit Cisco switch but still has 100 Mbps fibre devices in the building. Check the port type first: on Fast Ethernet or IE switches the FE version is the right part. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status from the switch and we help you find out whether it is the optic, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need a 100 Mbps multimode fibre link from a Cisco Gigabit SFP port to legacy FX equipment up to 2 km away.
Skip it if
The port is Fast Ethernet (GLC-FE-100FX), the far end is Gigabit, or the device is a media converter or NIC.
Also consider
