SFP-25G-ER-I — SFP28 25 Gbps

The SFP-25G-ER-I from Cisco is a long-reach 25 Gbps SFP28 module on single-mode fibre (SMF), compliant with the IEEE 25GBASE-ER standard and fitted with an LC (UPC) duplex connector. With an exceptional reach of 40 km and an industrial temperature range of -40 to 85°C, it is designed for very long-distance 25G links without the need for optical amplifiers on typical spans.

This module targets telecom operators and large enterprises seeking to establish 25G connections between datacenters or points of presence tens of kilometres apart over an existing single-mode infrastructure. The SFP-25G-ER-I distinguishes itself from short-reach 25G SR modules by its ability to cover 40 km under the 25GBASE-ER standard. Genuine Cisco hardware, manufacturer warranty.
