NEW Arista QSFP-100G-SR4 100GB BASE-SR4 850nm Short Reach MMF QSFP28 Transceiver

The Arista QSFP-100G-SR4 is a QSFP28 100GBASE-SR4 optical transceiver for 100G links over parallel multimode fiber. It transmits at 850nm. It reaches up to 70 meters on OM3 and 100 meters on OM4 and uses an MPO-12 UPC connector.

It is the standard short-reach 100G optic for links inside a data center. Use a matching 100GBASE-SR4 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 QSFP-100G-PSM4 100GBASE-PSM4 transceiver and the QSFP-100G-SWDM4 100GBASE-SWDM4 transceiver are also available. A seller refurbished QSFP-100G-SR4 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 QSFP-100G-SR4 is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
