The Cisco SFP-10G-LR-S is a high-performance 10GBASE-LR SFP+ optical transceiver module designed for long-reach single-mode fiber (SMF) deployments. Operating at a 1310nm wavelength and supporting distances up to 10km, this module is ideal for enterprise data centers, service provider networks, and campus core interconnects that demand reliable, high-speed 10 Gigabit Ethernet connectivity.


This unit is professionally refurbished by WhaleyComm's certified technicians and tested to original Cisco factory specifications, ensuring performance that meets or exceeds OEM standards. Each module undergoes rigorous inspection, cleaning, and functional validation before shipment — giving you enterprise-grade reliability at a fraction of new pricing.
