25GBASE-SR SFP Transceiver

The Arista SFP-25G-SR is a 25 Gigabit SFP transceiver designed for short-range optical networking. It connects switches, routers and servers inside data centres and enterprise LANs using multimode fibre. The module supports 25 Gigabit Ethernet links with a reach of up to 70 metres over OM3 fibre or 100 metres over OM4 fibre. It is built for environments that need high-density, low-power 25G connectivity.

Hot-pluggable SFP form factor

The hot-pluggable SFP form factor lets technicians insert or remove the module without powering down the host equipment. This reduces downtime during upgrades or maintenance and allows mixed-speed deployments on the same chassis. The transceiver draws low power, helping operators keep overall rack consumption down while populating many ports. It is fully compliant with the relevant IEEE specifications for multi-vendor interoperability.

Multimode fibre distance limits

Practical reach is limited to 70 metres on OM3 multimode fibre and 100 metres on OM4 multimode fibre. Links that exceed these distances will require single-mode optics or intermediate aggregation. The module does not support copper cabling or single-mode fibre, so it cannot be used for longer campus or metro runs. Buyers needing reaches beyond 100 metres must select a different transceiver type.
