Compatible 25GBase-SR SFP28 Transceiver

This transceiver is built for network links that run at 10 Gbps or 25 Gbps over short-range multimode fibre. It targets data-centre operators and enterprise IT teams who need a drop-in module for Cisco SFP-10/25G-CSR-S ports without paying OEM pricing.

25GBase-SR short-range multimode support

The module operates at the 25GBase-SR standard using an SFP28 form factor, so it fits any switch or router port that accepts that exact specification. It will not work in SFP+ slots limited to 10 Gbps or in long-reach single-mode environments.

Hot-pluggable SFP28 slot integration

Insert the transceiver directly into a compatible SFP28 cage on a switch line card or top-of-rack switch; no tools or chassis reboot are required. The hot-plug design frees a maintenance window and keeps adjacent ports online during installation.
