Rollball’s RQSFPDD-4Q56P401-DAC-xxm cable assembly is used in 4 X 100 Gigabit Ethernet links over copper cable, which provides connectivity between system units with a 400GbE connector on one side and four separate 100GbE connectors on the other four sides. The cable connects data signals from each of the 16 pairs on the single QSFP56-DD end to the dual pairs of each of the QSFP56 multiport ends.

Rollball’s RQSFPDD-4Q56P401-DAC-xxm cable assemblies is compliant with the QSFP-DD-MSA and IEEE802.3cd ,its  high performance, cost effective I/O solutions for LAN, HPC and SAN. The high speed cable assemblies meet and exceed 400Gigabit Ethernet, InfiniBand EDR /HDR and temperature requirements for performance and reliability.
