Gigabit SX SFP Module SFP-SX-MM850-550M
1000BASE-SX · 850nm · Multimode (MMF) · Duplex LC · 550m
100BASE-FX · 1310nm · Multimode (MMF) · Duplex LC · 2km
Compatible with major switch brands — share your equipment model to confirm coding before ordering. 3-year warranty included.
The 100BASE-FX SFP transceiver operates at 1310 nm over multimode fiber (MMF) with a duplex LC connector, delivering 100 Mbps Fast Ethernet up to 2 km. It plugs into any SFP MSA slot, is hot-pluggable, and follows the SFF-8472 management interface.
100BASE-FX remains the workhorse for legacy and industrial Ethernet: factory floors, substation and CCTV backhaul, and older switches that still run Fast Ethernet over multimode fiber.
Confirm your patch panels and cords are multimode before installing — mixing a single-mode cord onto a multimode link is the most common cause of a down link. Share your switch model to confirm coding; every module ships with a 3-year warranty and free technical support.
