SFP-25G-SR Arista Compatible 25G SFP28 SR 100m MMF Transceiver

Where an Arista SFP28 cage needs its short-reach member, the SFP-25G-SR is the drop-in: 25G over multimode fiber, 100m of reach, duplex LC termination. Arista hosts read it as a native optic, so it can hold a spare-shelf position or go straight into a new leaf build without any port-level configuration.
