Description

An industrial-temperature 25 gigabit SFP28 optic for 40 km single-mode spans at about 1310 nm. It fits mobile transport, remote-site backhaul and long data-centre interconnects where temperature swings are expected. The module is rated for minus 40 to 85 degrees Celsius. Cabling is a single-mode duplex pair with LC PC or UPC connectors. The SFP-25G-ER-I 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 industrial temperature range of minus 40 to 85 degrees Celsius. Its listed reach is 40 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

Metro and long-haul links between sites
Service-provider aggregation over dark fibre
