Arista 400GBASE-CR8 QSFP-DD to QSFP-DD Twinax Copper Cable, 2 m
CAB-D-D-400G-2M · Refurbished · 1 year warranty
Quantity (units)
Overview
Two meters gives some room for routing, and the Arista CAB-D-D-400G-2M uses it on a QSFP-DD to QSFP-DD copper link at 400GbE. The title names the cable 400GBASE-CR8 twinax.
With 2 m you can connect devices a few rack units apart or in adjacent racks when they sit close. Copper keeps the link simple: no optics to source and no fiber to clean, and each end already has its connector.
Order by length first, because every size is its own part number. Check that both devices have QSFP-DD ports, since the cable will not seat in other cage types. This 2 m cable is offered new, refurbished or used, with 1 year or 3 years of warranty for the first two and 90 days for used.
