The Cisco SFP-10G-LRM uses the 10GBASE-LRM standard, designed specifically to run 10 Gigabit Ethernet over existing multimode fiber runs that were originally installed for slower speeds, extending their useful reach further than a standard 10GBASE-SR short reach transceiver would allow. This makes it a practical upgrade path for buildings with older multimode fiber already in place rather than needing to install new single mode fiber. Antofity Concepts supplies the SFP-10G-LRM for organisations in Kenya upgrading existing multimode fiber links to 10 Gigabit speed.
