SFP-1GE-LX Juniper Compatible 1G SFP LX 10km SMF Transceiver

Fitting the SFP-1GE-LX is a like-for-like exchange carrying two of the Juniper original's key specs into the swap: a 1G SFP LX optic operating at 1310nm over single-mode fiber. It reaches 10km, seats in a standard SFP cage, and comes up as a recognized module with no configuration required.
