Amphenol Commercial QSFP Double Density (DD) Cable Assemblies provide a 200G / 400G / 800G solution by doubling the number of channels from 4 to 8 lanes compared to existing 100G QSFP cabling systems. This feature enables more bandwidth within the same mechanical envelope. These copper cable assemblies are compatible with 25G/lane NRZ up to 112G/lane PAM4 signaling protocols, enabling the delivery of aggregate bandwidths of 200G, 400G, and 800G per cable assembly. The QSFP DD assemblies are available in both passive and active variants, with 112G passive cable lengths up to 2m and 112G active cable lengths up to 4m. Other features include backward mating compatibility with QSFP receptacles and an optimized PCB interface board with auto-soldering processes. These cables are assembled with twin-axial SKEWCLEAR® 8-pair or 16-pair wire for softer and improved bending performance over standard cables.
