15327-SFP-LC-LX Cisco Compatible 1G SFP LX 10km SMF Transceiver

Reaching 10km over single-mode fiber, the 15327-SFP-LC-LX is a 1G LX SFP built for the long campus and inter-building links where multimode runs out. LX signalling over one SMF pair lets it carry Gigabit Ethernet across those spans while dropping into a standard SFP cage. That reach is the defining trait here: it bridges the gap between short in-building copper and true metro optics on a single fiber grade.
