QSFP112 Active DAC Cable

Volex’s QSFP112 active copper Direct Attach Cable features 4 transmitting and 4 receiving 100Gbps PAM-4 channels. The cable assembly meets IEEE 802.3ck 400GBase-CR4, 200GBase-CR2 and 100GBase-CR1 specifications. The Volex QSFP112 active DAC enhances Signal Integrity severely stressed under high-speed data rate through advanced linear equalisation. The result is up to 5M reach vs. max 2M reach for the passive version and smaller cable size and higher flexibility.

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. The Volex QSFP112 active DAC is designed to meet the next-gen data centre needs and, at less than 150mW per active channel, is a cost-effective alternative to the high-power consumption Active Optical Cable.

QSFP112 Active 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
