25G SFP28 transceiver for Arista networks

The Axiom SFP-25G-MR-XSR-AX is a 25G SFP28 transceiver built for 100 percent compatibility with Arista switching and routing platforms. It arrives pre-configured with the application-specific code required by the OEM, so the module is recognised immediately on insertion. Network engineers deploying or expanding 25G links in Arista environments can install it without additional provisioning steps.

Fits standard SFP28 cages and MSA platforms

The module conforms to the multi-sourcing agreement, allowing it to operate in any MSA-compliant SFP28 cage across mixed-vendor networks. Its standard form factor means no special brackets, adapters or cabling changes are needed beyond a compatible duplex LC fibre patch cord. Because it functions identically to the original Arista part, it frees procurement from single-source purchasing while maintaining full interoperability with existing 25G infrastructure.

Replaces OEM Arista 25GBASE-SR modules

This transceiver directly substitutes the Arista-branded 25GBASE-SR optic at a lower acquisition cost while delivering the same link performance and diagnostic visibility. The jump is worth it when budget constraints demand multi-vendor sourcing or when spare inventory must cover several hardware generations without maintaining separate SKUs. It is not suited for links requiring longer reach than the SR specification or for single-mode fibre deployments.

Questions about this item

What is the maximum data rate the SFP-25G-MR-XSR-AX can sustain continuously?

The module is built for a 25 Gb line rate and complies with the MSA specification, so it maintains that throughput as long as the host port and cabling support it.

How much power does the transceiver draw and what thermal load should I expect in a fully populated chassis?

Power consumption follows the SFP28 MSA limits for 25G SR optics; the module runs at the standard low-power envelope, so heat output stays within the chassis design budget when all ports are active.

Which switch or router ports accept this transceiver without additional adapters?

Any MSA-compliant SFP28 cage that supports 25GBASE-SR will accept the SFP-25G-MR-XSR-AX; it is pre-coded for Arista and works in other MSA platforms without adapters.
