The Arista QDD-400G-DR4 is a QSFP-DD 400GBASE-DR4 optical transceiver for 400G links over parallel single-mode fiber. It transmits at 1310nm. It reaches up to 500 meters and uses an MPO-12 APC connector.
It interoperates with four 100GBASE-DR optics up to 500 meters, so one 400G port can feed four 100G ports. Use a matching 400GBASE-DR4 optic at the far end of the link unless Arista lists the pairing above, and use single-mode patch cables.
If you need a different reach, the QDD-400G-SR8 400GBASE-SR8 transceiver and the QDD-400G-XDR4 400G-XDR4 (4x 100GBASE-FR) transceiver are also available. A seller refurbished QDD-400G-DR4 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.
Single-mode fiber is normally run in yellow jacketed patch cables, so check that every patch cord and panel in the path is single-mode before you connect it.
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.
