Arista 400GBASE-DR4 QSFP-DD Transceiver, 500 m Parallel Single-Mode
QDD-400G-DR4 · Refurbished · 1 year warranty
Quantity (units)
Overview
The Arista QDD-400G-DR4 uses single-mode fiber. It is a QSFP-DD module at 400GbE, titled 400GBASE-DR4, using parallel single-mode fiber with a reach of 500 m.
Five hundred meters covers most campus and data hall distances, including links between rows or between halls in the same building. Because the fiber is parallel rather than duplex, the cabling needs to support a parallel arrangement; a plant built only for duplex pairs would need changes. Tell us your fiber type and the distance of the longest link, and we will confirm that the module fits before you order.
The module is a single-port unit, so each 400G link needs one at either end. This module is offered as a new or refurbished unit, and either condition carries a choice of 1 year or 3 years of warranty.
