Cisco GLC-LH-SMD-RF 1000BASE-LX/LH SFP 1 GbE | SFP Module, Refurbished — GLC-LH-SMD-RF

Keep critical fiber links active with a Cisco Certified refurbished GLC-LH-SMD-RF SFP transceiver. Designed for 1000BASE-LX/LH deployments, it supports both multimode and single-mode fiber, giving network teams flexibility when extending Gigabit Ethernet across campus, wiring closets, and distribution paths. The 1310 nm optical design is a proven fit for longer-reach 1 GbE links, while DOM support adds operational insight for monitoring optical performance and link health. That matters when you need predictable behavior from access switches, storage networks, or inter-building runs without paying for a new module. Because this is a Cisco-certified refurbished part, it offers a practical way to source a known-good transceiver for standard enterprise fiber environments. It is a strong choice when compatibility, reach, and lifecycle value matter more than chasing unnecessary extras. For teams maintaining mixed fiber plants, this module helps preserve uptime while keeping procurement aligned with budget and standards.
