The Cisco GLC-LX-SM-RGD is a rugged-rated 1000BASE-LX/LH Small Form-Factor Pluggable (SFP) transceiver module designed for extended temperature environments and demanding enterprise deployments. Built for single-mode fiber (SMF), this SFP delivers reliable Gigabit Ethernet connectivity over long distances, making it ideal for data centers, enterprise networks, and industrial applications where standard transceivers may fall short.
This unit is professionally refurbished by WhaleyComm's certified technicians and tested to original Cisco factory specifications. You receive enterprise-grade performance at a fraction of the new cost — with no compromise on quality or reliability.
