Description

A dual-rate single-mode SFP28 optic at 1310 nm that supports 10G and 25G operation. Use it for campus and metro uplinks, or for fronthaul-style links where 25G must cross several kilometres of fibre. RS-FEC is required on the host port for 25G operation. Fibre is G.652 single-mode in a duplex pair with LC connectors. The SFP-10/25G-LR-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 10 km on SMF. 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

Campus links between buildings over single-mode fibre
Data-centre interconnects between halls or floors
Aggregation and core uplinks where multimode reach is not enough
