Description

The Arista SFP-25G-LR is a hot-swappable 25GBASE-LR SFP28 optical transceiver from the Arista 25G SFP28 optics range. It runs 25 Gigabit Ethernet over duplex single-mode fibre with an LC connector, making it suited to 25GbE data centre and campus links such as switch-to-switch or leaf-spine connections between rooms and buildings.

The module operates at a 1310 nm wavelength over G.652 single-mode fibre and reaches up to 10 km. Transmit power is -7 to 2.0 dBm and receive power is -13.3 to 2.0 dBm. Maximum power consumption is 1.5 W, and the SFP form factor keeps the footprint small and the power draw low for dense port deployments.

It fits Arista SFP25 (SFP28) ports. Related Arista variants include the SFP-25G-MR-LR dual-rate 10/25G LR module, the SFP-25G-LR-E enhanced low-latency module and the SFP-25G-ER for 40 km links.
