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

For in-building and intra-campus links where the run stays inside 550m of multimode fiber, a short-reach 1G optic is the right tool — and that is what the EX-SFP-1GE-SX provides. This SX-grade SFP drives MMF over a duplex LC and reports DDM diagnostics to the host for real-time link monitoring. The 550m ceiling puts it squarely on multimode plant inside a facility or across a campus, the short hops where pulling single-mode would be overkill and the existing MMF cabling already reaches. It comes up on Juniper switching gear as a recognized module with no configuration step, hot-swapping into a live port and passing 1G the moment it seats.
