SolarFlare-compatible 25GBASE-SR transceiver

The Axiom SOLR-SFM25G-SR-LL-AX is a new SFP28 transceiver built for 25GBASE-SR links over multimode fibre. It uses an 850nm wavelength and LC duplex connectors to reach 100m on OM3 or OM4 cable. The module is pre-coded for SolarFlare equipment and MSA-compliant for broad switch interoperability.

Replaces vendor-branded 25G SR optics

This unit substitutes the original SolarFlare 25GBASE-SR module at a lower cost while keeping identical form, fit and function. The jump is worth it when a data-centre rack needs multiple 25G uplinks and the budget favours a qualified third-party alternative that still guarantees OEM-level compatibility.

Limited to 100m on multimode fibre

The 850nm VCSEL source restricts reach to 100m on OM3 and OM4 multimode fibre, so longer building-to-building runs need single-mode optics instead. The LC interface fits standard SFP28 cages, but the module will not negotiate speeds below 25G and requires a host port that supports 25GBASE-SR signalling.

Questions about this item

What patch cable and fiber type does the LC duplex port on this 25GBASE-SR module require?

Use an LC duplex patch cord with OM3 or OM4 multimode fiber; the 850nm wavelength is rated for 100m on those cable grades.

Which slot accepts the SFP28 form factor, and what coding step prevents a port error?

Insert the module into any SFP28 or SFP+ cage; the pre-loaded SolarFlare application code lets the switch recognise it immediately without manual EEPROM programming.

When should the LC connectors be cleaned, and what tool is appropriate?

Clean both LC ferrules with a one-click cassette cleaner before first insertion and whenever link errors appear; avoid alcohol wipes that leave residue on the 850nm optics.
