400G PAM4 QSFP-DD to 2×200G QSFP56 Direct Attach Copper Cable (DAC), PVC, Passive, up to 3 m (10 ft)
Overview
The NS 400G PAM4 QSFP-DD to 2×200G QSFP56 Direct Attach Copper Cable (DAC) is a breakout copper interconnect designed for 400G-to-2×200G Ethernet connectivity in large-scale data centers, cloud infrastructures, and HPC environments.
Built with twinax copper cable and a PVC jacket, it offers 400 Gbps aggregate bandwidth split into two 200G channels via 8×50 Gbps PAM4 lanes. The passive version supports lengths up to 3 m (10 ft) with virtually zero power consumption, making it an ideal choice for short-range, in-rack deployments.
For extended reach, active DACs support up to 5 m (16 ft) while consuming ≤ 4 W per end. Its low latency, robust EMI immunity, and cost advantage over optical solutions make it perfect for high-density interconnect applications.
Compatible Brands
The NS 400G QSFP-DD to 2×200G QSFP56 DAC is validated to work seamlessly with switches and servers from Juniper, Arista and Dell.
