Cisco GLC-GE-DR-LX-RF 1000BASE-LX SFP 1310 nm | Enterprise Fiber — GLC-GE-DR-LX-RF

Keep critical fiber links online with a Cisco SFP designed for 1000BASE-LX connectivity and dual-rate operation. The GLC-GE-DR-LX-RF uses 1,310 nm optics and a compact SFP form factor to support Gigabit Ethernet deployments where link stability matters more than excess feature count. This remanufactured module is a practical fit for teams extending switch-to-switch or switch-to-server connections across longer fiber spans. It gives you a Cisco-qualified path to replace failed optics, standardize spares, or expand an installed base without changing the network design. For procurement teams, the remanufactured format can reduce acquisition cost while preserving compatibility with Cisco environments that call for this exact MPN. Choose this module when you need a straightforward optical transceiver for enterprise fiber infrastructure, not a general-purpose part with uncertain fit. It is built for operators who know the port, the fiber plant, and the distance requirement already — and need a replacement that matches the spec sheet, not a guess.
