Purpose-built 40G transceiver

The Axiom SFM40G-SR4-AX is a 40GBASE-SR4 QSFP+ transceiver qualified for Solarflare network adapters. It provides a 40 Gigabit Ethernet link over multimode fibre for data-centre and high-performance-computing clusters. The module targets administrators who need a vendor-approved optic for existing Solarflare hardware.

Build integration

The QSFP+ form factor plugs directly into compatible Solarflare ports without an adapter cage. Its 0.22 pound weight adds negligible load to the front-panel density budget. The SR4 optical interface frees up copper uplink ports and supports standard OM3 or OM4 patch cables for short-reach rack-to-rack runs.

Included accessories

No separate accessories or software utilities are bundled with the transceiver. The unit ships as a single tested module ready for immediate installation. Administrators rely on the host adapter firmware and driver stack for link negotiation and monitoring.
