Arista 400GBASE-CR8 QSFP-DD to QSFP-DD Twinax Copper Cable, 1 m
CAB-D-D-400G-1M · Refurbished · 1 year warranty
Quantity (units)
Overview
One meter of copper is all the Arista CAB-D-D-400G-1M offers, and for the right link that is exactly enough. It is a 400GBASE-CR8 twinax cable that joins two QSFP-DD ports at 400GbE.
A cable this short fits between neighboring devices in the same rack, such as a switch and a server, or two switches mounted one above the other. With the connectors built into the cable, there are no separate modules to buy for either end, which keeps the bill of materials short.
Because the length is fixed, measure from port to port including the bend at each connector before you commit. The cage type matters too: the cable has QSFP-DD ends, so both devices need QSFP-DD ports. This cable can be ordered new, refurbished or used, with 1 year or 3 years of warranty on new and refurbished units and 90 days on used.
