Description
The QFX-prefixed code for the 1000BASE-LX SFP, which maps to the same Juniper part code, 740-011614, as the EX-prefixed version. Network teams use it for Gigabit uplinks over single-mode cabling, for example from a data-centre management switch to a core device in another hall. Duplex LC connectors and 1310 nm optics keep installation straightforward, and diagnostics expose transmit and receive power for link troubleshooting. Cabling for QFX-SFP-1GE-LX: use a duplex single-mode (OS2) patch cable with LC connectors. The headline reach is 10 km on SMF · 550 m on MMF (mode-conditioning), 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.
