NEW Arista SFP-25G-SR 25GB BASE-SR 850nm MMF SFP28 Optical Transceiver

The Arista SFP-25G-SR is a SFP28 25GBASE-SR optical transceiver for 25G links over multimode fiber. It transmits at 850nm. It reaches up to 70 meters on OM3 and 100 meters on OM4 and uses a duplex LC connector.

It is the standard short-reach 25G optic for links inside a data center. Use a matching 25GBASE-SR optic at the far end of the link unless Arista lists the pairing above, and use multimode patch cables of the grade your reach requires.

If you need a different reach, the SFP-25G-LR 25GBASE-LR transceiver and the SFP-25G-MR-XSR 10/25GBASE-MR-XSR transceiver are also available. A seller refurbished SFP-25G-SR is also available.

Arista publishes a transceiver compatibility guide that lists which switch platforms and EOS releases support each module, so check it for your switch before you order.

OM3 and OM4 multimode patch cables are normally aqua, and some OM4 cables are violet. Check that every patch cord and panel in the path matches the fiber grade your reach requires.

Keep the dust caps on the optic and the fiber until you are ready to connect them, and clean the connector end faces before you plug them in. Most failed optical links come down to a dirty connector.

This SFP-25G-SR is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
