Port mode and breakout requirements

Arista lists QDD-400G-XDR4 for 400G-XDR4 or four 100GBASE-FR optical links. For breakout, verify the host port mode, software support, FEC settings, lane mapping, remote optics and fiber assembly together. A QSFP-DD cage alone does not establish that a particular switch supports the intended configuration.

产品描述

Choosing a 400G parallel-fiber link

The used Arista QDD-400G-XDR4 listing is a candidate for 400G links up to 2 km over parallel single-mode fiber. It uses a QSFP-DD host interface and an MPO-12 APC optical connector. Check the installed fiber and both endpoint platforms before selecting a module.

Check the connector, not just the distance

A duplex LC fiber pair is not the specified connection for this module. Include connector type, fiber polarity, link loss and patch-panel layout in your request. The base QDD-400G-XDR4 is not the XDR4-S connector variant or the XDR4-C channelized variant.

See the Arista transceiver datasheet, 400G QSFP-DD ordering table for the exact part number. These are manufacturer design specifications, not test results for the offered used unit.

Compare optical transceiver options or request a quote. Include quantity, destination country and city, target arrival date, and host model. Availability, dispatch origin, freight, customs responsibility and seller support must be confirmed in the written quote.

Before accepting a used unit

Request the exact part number and hardware revision, serial-level traceability, connector inspection and available link-test records. Ask which host, software, speed and test conditions were used. Confirm the warranty provider, duration, return conditions and return-shipping responsibility for the quoted unit. A catalogue stock label is not evidence that these checks have been completed.
