The T1-DAC-400G QSFP DD copper direct-attach cable is suitable for very short distances (up to 3m) and are used as a cost-effective solution for establishing a 400Gbps link between QSFP ports. This DAC is compliant with IEEE802. 3ck and SFF-8636 MSA standards. It is suitable for cost effective close range interconnections within equipment room. 3M 9V4 series 400G QSFP-DD direct-attach copper (DAC) cable assemblies are passive copper cable assemblies that utilize 3M twin axial cable technology to create a highly flexible, foldable, high-performance solution with bandwidths up to 400 Gbps to connect servers, switches, storage, and other. High-speed I/O passive cable assemblies that can deliver data rates as high as 400 Gbps with a variety of lengths or customized options for greater design flexibility. The Quad Small Form-factor Pluggable Double Density (QSFP-DD) Interconnect Solution is specifically designed to meet high-density. NVIDIA ® LinkX ® Ethernet DAC cables are the lowest-cost way to create high-speed 100G–400G links in Ethernet switching networks and for NVIDIA GPU-based systems. These cables provide low-latency, high-bandwidth solutions suitable for modern data center demands. Designed for high-density cabling interconnect systems, this DAC is capable of delivering is fully.
