Overview
The -C suffix on Arista QDD-400G-SR8-C is worth noticing. Its title lists 400GBASE-SR8 together with 8x50G-SR and 25G-SR, so the module is described as serving more than one signalling mode, not just a single 400G link.
The physical details are straightforward: QSFP-DD form factor, multimode fiber (OM4 in the title), 400GbE port speed and a specified reach of 100 m. Choose this version when your design calls for the extra modes named in the title, and confirm the port configuration on your switch before you order.
It is a single-port module for short in-building links. Stock can be requested in any of the three conditions. New and refurbished units carry 1 year or 3 years of warranty, and used units carry 90 days.
