The Cisco SFP-10G-SR 10GBase-SR SFP module is for duplex optical data communications. Unlike other transceivers designed for single mode fiber cable, Cisco SFP-10G-SRis designed for multi-mode fiber. It operates at an optical wavelength of 850 nm, and offers a wide range of options for Ethernet connectivity, including for service provider transport and data center applications.
It supports a distance of 26 meters on standard FDDI grade multi-mode fiber, and has the SFP+ 20-pin connector for hot plug capability.
