Description

A 25 gigabit short-reach SFP28 optic running at 850 nm over duplex multimode fibre. It is the typical server-to-leaf link in 25G data-centre racks and in high-performance computing clusters. The host port needs RS-FEC enabled. Reach is 70 m on OM3 and 100 m on OM4 or OM5, using LC duplex patch cords. The SFP-25G-SR-S is a SFP28 form-factor part for SFP28 ports on 25 gigabit leaf switches and server adapters. It runs over a duplex fibre pair and is specified for the commercial temperature range of 0 to 70 degrees Celsius. Its listed reach is 70 m on OM3 · 100 m on OM4/OM5. Check the link budget against the real fibre plant, including connectors and splices, before relying on the headline distance. Because compatibility is decided per platform and software release, confirm the exact host device in the Cisco compatibility matrix before ordering.

Typical uses

Server and storage links to a top-of-rack switch
Switch-to-switch links inside one data hall or comms room
Building risers that already have OM3/OM4 multimode fibre
