Overview
Energy efficiency is the selling point of the Arista QDD-400G-ZR-EE, according to its title. It is a 400GBASE-ZR QSFP-DD digital coherent tunable transceiver on single-mode fiber, with a reach of up to 120 km.
A lower-power design matters when many ports are populated in one chassis, because thermal and power budgets limit how many long-reach modules a switch can carry. The EE in the part number marks that design choice. Send the switch model and the number of ports you plan to populate so that we can check this module against your needs.
If thermal limits in your switch are a concern, this is the variant to raise with us. The module has one port and fits QSFP-DD cages. It is available as a new or refurbished module with 1 year or 3 years of warranty.
