QSFP56 to 4x SFP56 Active Breakout DAC Cable

Volex’s QSFP56 active breakout Direct Attach Copper cables feature 4 transmitting and 4 receiving 50Gbps PAM-4 channels and support 200Gbps (QSFP56) to 4x 50Gbps (4x SFP56) breakout configurations. The cable assemblies meet 50G and 100G Ethernet standards. These active breakout DAC’s enhance Signal Integrity, which is severely stressed under high-speed data transmission, through advanced linear equalization. The result is longer reach up to 9M vs max 3M for the passive version and smallest cable size and highest flexibility.

Next-gen data centres need high performance cables that reduce power consumption, provide reliable operation and are low cost. Volex’s QSFP56 active breakout DACs are a cost-effective alternative to the high-power consumption Active Optical Cable with superior reliability for deployment at faster speed in a tighter space.

QSFP56 to 4x SFP56 Active Breakout DAC Cable Product Highlights

  • Low power consumption and heat dissipation
  • Complete cable assembly uniquely terminated at the factory to provide the most reliable operation
  • 100% tested for signal integrity with serial number traceability
