OSFP 400G Passive DAC Cable

Volex’s OSFP 400G passive Direct Attach Copper cable features 8 transmitting and 8 receiving 50Gbps PAM4 channels for 400G operation. The cable assembly meets IEEE 802.3cd 200GBase-CR4, 100Gbase-CR2 and 50GBase-CR 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 OSFP 400G cable is designed to meet the next-gen data centre needs. With unique foam dielectric construction, Volex OSFP 400G cable offers smallest cable outer diameter and bend radius, and highest flexibility, while meeting or exceeding the MSA signal integrity specification.

OSFP 400G 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
