ONS-SE-G2F-LX Cisco Compatible 1G SFP LX 10km SMF Transceiver

Swapping in for the Cisco ONS-SE-G2F-LX is a like-for-like exchange: same 1G LX optics reaching 10km over single-mode fiber, in the SFP form factor. LX is the standard choice for gigabit spans that outrun short-reach optics but stay inside metro distances, and this module holds to that same 10km single-mode envelope. Because it reads to the host as the original part, the port comes back up on Cisco gear with no configuration step, and the existing link design is left intact rather than re-engineered around a new optic.
