The 400G QSFP-DD Direct Attach Cable (DAC) series provides ultra-high-speed, low-latency connectivity for next-generation data centers, high-performance computing (HPC), and AI/ML clusters. In modern data centers and enterprise networks, Quad Small Form-factor Pluggable (QSFP) cables are everywhere. They connect servers, switches, and storage at speeds from 40G to 400G and beyond. Thanks to their four-lane parallel architecture, QSFP cables combine high bandwidth with compact design. hin or between adjacent racks. As a passive cable, it requires no external power, relying on host d romagnetic interference (EMI). Its robust desi d high-performance networking. The plug-and-play functionality simplifies d ed for active optical modules. Available in various lengths, it adapts to. Amphenol's QSFP DD (Quad Small Form Factor Pluggable Double Density) copper cable assemblies double the number of channels from 4 to 8 lanes when compared to the existing QSFP cabling systems, enabling more bandwidth within the same mechanical envelope. QSFPTEK's 400G DAC is fully compliant to.
