SKU CH-34GS-TDZRW MPN 25G-SR-SFP100M

A 25G SR SFP28 transceiver module connects servers over 100m of multimode fibre

  • 25 Gbps throughput for high-speed server links
  • SR optics reach 100 metres over multimode fibre
  • SFP28 form factor fits standard server cages
  • Hot-pluggable design enables live module swaps
  • First listed by the manufacturer in 2020

25G SR SFP28 Transceiver Module

The Extreme Networks 25G-SR-SFP100M is a short-range SFP28 transceiver rated for 25 Gbps links over multimode fibre up to 100 metres. It plugs into any SFP28 port on a server, switch or storage array that requires 25G SR connectivity. First listed by the manufacturer in 2020, the module ships new and ready for deployment.

Network teams needing 25G SR links up to 100 m

This transceiver suits data-centre builds that run 25G SR optics on OM3 or OM4 fibre within a single rack row. It does not suit teams who need longer reach, single-mode fibre or direct-attach copper cables, and it cannot be used in legacy 10G-only SFP+ slots that lack 25G support.

100-metre reach on multimode fibre

The 100 m distance rating is the single figure that determines whether this module fits the link budget. If the fibre run exceeds 100 m or the path uses single-mode cable, a different optic is required.
