Arista QSFP-100G-SRBD 100GB BASE-BIDI OM3/100m OM4 MMF QSFP28 Transceiver

The Arista QSFP-100G-SRBD is a QSFP28 100GBASE-BIDI (SRBD) optical transceiver for 100G links over duplex multimode fiber. It transmits at 855 and 908nm. It reaches up to 70 meters on OM3 and 100 meters on OM4 and uses a duplex LC connector.

It is bidirectional, so it runs 100G over a single duplex multimode pair and lets you reuse existing duplex LC cabling. Use a matching 100GBASE-BIDI 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-SR4 100GBASE-SR4 transceiver are also available. A new QSFP-100G-SRBD 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 seller refurbished QSFP-100G-SRBD is tested, working, and covered by the NetworkTigers one-year warranty.
