Axiom 25GBASE-SR SFP28 Transceiver

This SFP28 transceiver delivers 25 Gbps connectivity over multimode fibre for enterprise switches and routers. It targets network engineers who need a drop-in module for short-reach links in data-centre or campus environments.

100-metre reach at 850 nm

The module operates at 850 nm wavelength and supports a maximum distance of 100 metres on OM3 or OM4 multimode fibre with LC duplex connectors. This single distance figure determines whether the part fits the planned link length.

Pre-coded OEM compatibility

Each unit ships pre-programmed with an application-specific code that matches major router and switch vendors, removing the need for manual configuration. Full MSA compliance ensures the transceiver functions identically to original modules in multi-vendor networks.
