Cisco SFP-10G-LR 10GBASE-LR SFP+ Transceiver — 10 km
When your high-speed network requires long-reach 10 Gigabit Ethernet over fiber, the genuine Cisco SFP-10G-LR SFP+ transceiver is the trusted choice. Factory-sealed and Cisco-compliant, it supports 10GBASE-LR up to 10 km over single-mode fiber using a 1310 nm DFB laser. With DOM (Digital Optical Monitoring) and full SFP+ MSA compatibility, this hot-swappable module integrates seamlessly into Cisco Catalyst, Nexus, ASR, and UCS platforms.
LR (Long Reach) vs. SR (Short Reach): Choose LR for long-distance connections up to 10 km over Single-Mode Fiber (SMF), ideal for connecting buildings or spanning campus networks. Choose SR for short-range links within a data center—typically up to 300 m—using Multi-Mode Fiber (MMF).
