The nVidia MCP1660-W01AE30 is a 1.5 m QSFP-DD direct attach cable designed for 400 Gbps Ethernet links. It features QSFP-DD connectors on both ends in a passive copper DAC form factor, supporting high-speed point-to-point data transmission between compatible QSFP-DD ports.

This cable is intended for short-range interconnects between switches, routers, and servers equipped with 400 GbE QSFP-DD interfaces. The passive design draws power from the host ports and requires no external power source. It supports direct connection within racks or between adjacent racks where low-latency, high-bandwidth copper links are required.
