Module overview

Hot-pluggable SFP MSA form factor
DDM digital diagnostics for TX/RX monitoring
3-year warranty · free technical support
Coding confirmed against your switch model

The 1000BASE-SX SFP transceiver operates at 850 nm over multimode fiber (MMF) with a duplex LC connector, delivering 1.25 Gbps line-rate up to 550 m. It plugs into any SFP MSA slot, is hot-pluggable, and follows the SFF-8472 management interface.

Typical deployments

Multimode links like this are the default inside buildings and data centers: rack-to-rack runs, floor-to-floor backbones and short campus spans over OM1–OM4 fiber. Connect straight to LC patch panels — no mode-conditioning cord needed.

Before you order

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.
