Cisco GLC-LX-SM-RGD-RF 1G SFP Single-Mode LC/PC | Gigabit Ethernet — GLC-LX-SM-RGD-RF

Keep critical fiber links stable with a Cisco-certified refurbished SFP designed for Gigabit Ethernet over single-mode fiber. The GLC-LX-SM-RGD-RF provides 1000Base-LX/LH connectivity through a duplex LC/PC interface, making it a practical fit for uplinks that need consistent optical performance in demanding network environments. Its hot-swappable form factor helps reduce maintenance disruption, while the single-mode design supports longer-distance fiber runs than short-reach copper alternatives. That matters when you are extending connectivity across plant floors, remote cabinets, or ruggedized network segments where uptime and serviceability carry real cost. This module is a strong choice when you need Cisco compatibility without paying for a new-build optic. It aligns with Cisco IE3000 and IE3010 switches, Cisco 2500 Connected Grid Switch Series, Cisco 2000 Connected Grid Router Series, Cisco 3200 Series Rugged Routers, and Cisco MWR 2941 Mobile Wireless Routers. For teams standardizing on Cisco infrastructure, it offers a straightforward way to restore or expand optical ports with a known-fit component. Ideal For Extend uplinks between Cisco industrial switches and remote fiber closets Restore failed optical ports in ruggedized Cisco router and switch deployments Add single-mode Gigabit connectivity to distributed data networking infrastructure Standardize spare optics for Cisco edge and connected grid environments Why This Product 1 Cisco-certified refurbished option for lower acquisition cost 2 Single-mode LX/LH support for longer fiber runs 3 Hot-swappable design for faster maintenance windows 4 Compatible with Cisco industrial and rugged networking platforms
