SRX-SFP-1GE-SX Juniper Compatible 1G SFP SX 550m MMF Transceiver

A 1G SX SFP running 550m over multimode fiber on a duplex LC pair — the Juniper-coded version of exactly that optic is the SRX-SFP-1GE-SX. The SX designation and multimode media put it in the short-haul role, linking switches across a floor or campus riser where multimode is already run. It arrives coded to register on Juniper hosts as a native SFP, seats hot with no configuration pass, and reports DDM diagnostics over the 550m link.
