QSFP-DD800 Passive DAC Cable
Volex’s 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 centres deploy faster speed in a tighter space, they need high performance cables that reduce power consumption, provide reliable operation and are low cost. Volex’s QSFP-DD800 cable is designed to meet the next-gen data centre needs. With unique foam dielectric construction, Volex QSFP-DD800 cable offers smallest cable outer diameter and bend radius, and highest flexibility, while meeting or exceeding the MSA signal integrity specification.
QSFP-DD800 Passive DAC Cable Product Highlights
- Near zero power consumption and no heat generated
- Complete cable assembly uniquely terminated at the factory to provide the most reliable operation
- 100% tested for signal integrity with serial number traceability
