Product Overview
The Cisco GLC-LX-SM-RGD is a rugged 1000BASE-LX SFP transceiver built for harsh industrial environments. It supports Gigabit Ethernet over single-mode fiber (SMF) at distances up to 10 km, and limited multimode support with a mode-conditioning patch cord. Operating at 1310 nm, it’s ideal for industrial Ethernet, outdoor networks, and temperature-critical deployments, with an extended operating range from –40°C to +85°C.
