Description

AlphaBridge QSFP-DD800 (Double Density) Passive Direct Attach Copper Cable features 8 transmitting and 8 receiving 100Gbps PAM4 channels for 800G operation. The cable assembly meets IEEE 802.3ck 400GBase -CR4, 200Gbase-CR2, and 100GBase-CR1 standards with substantial signal integrity margin providing high performance and bandwidth interconnect solutions for high-density applications.

As next-gen data centers deploy faster speed in a tighter space, they need high-performance cables that reduce power consumption, provide reliable operation, and are low-cost. AlphaBridge QSFP-DD800 cable is designed to meet the next-gen data center needs. With unique foam dielectric construction, Volex QSFP-DD800 cable offers the smallest cable outer diameter and bend radius, and the highest flexibility, while meeting or exceeding the MSA signal integrity specification.
