Overview

The S in Arista QDD-400G-XDR4-S stands for the SN connector named in the title. The numbers otherwise follow the XDR4 standard: 400GbE, QSFP-DD, parallel single-mode fiber and a 2 km reach.

Connector type decides which patch cords you buy, so this module is mainly a cabling decision. Check the connector at the far end and the panel in between before you commit, since mixing connector styles forces extra adapters. Ask for the matching module for the other end of the link at the same time, so that both sides arrive together and can be tested before installation.

A 2 km reach is enough for building-to-building runs on a campus. The module is a single-port unit that fits QSFP-DD cages. This SN version is available in new and refurbished condition, with a choice of 1 year or 3 years of warranty.
