Description
The QFX-prefixed code for the 1000BASE-SX SFP, sharing Juniper part code 740-011613 with its EX-prefixed twin. It suits Gigabit server and management connections in data-centre racks, and short campus runs between wiring closets on existing multimode plant. Transmit wavelength is specified between 770 and 860 nm, and the module reports temperature, bias, power and voltage through its diagnostics interface. Cabling for QFX-SFP-1GE-SX: use a duplex multimode patch cable with LC connectors, OM3 or OM4 preferred for the longest reach. The headline reach is 550 m on 50/125 µm MMF · 275 m on 62.5/125 µm MMF, so measure the installed link loss before ordering. The host needs a free SFP cage that runs at 1G; Juniper's tool names EX4400, EX4300, EX4100 among the platforms where this code is supported, and the model page also gives the minimum software release for each platform. Clean the connectors before insertion and keep dust caps on unused ports.
