Arista OSFP-400G-XDR4 400GBASE-XDR4 up to 2km over parallel SMF OSFP Transceiver

The Arista OSFP-400G-XDR4 is a OSFP 400G-XDR4 (4x 100GBASE-FR) optical transceiver for 400G links over parallel single-mode fiber. It transmits at 1310nm. It reaches up to 2 kilometers and uses an MPO-12 APC connector.

It breaks out into four 100GBASE-FR links up to 2 kilometers, so one 400G port can feed four 100G ports. Use a matching 400G-XDR4 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 OSFP-400G-SR8 400GBASE-SR8 transceiver and the OSFP-400G-DR4 400GBASE-DR4 transceiver are 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.

This seller refurbished OSFP-400G-XDR4 is tested, working, and covered by the NetworkTigers one-year warranty.
