200G PAM4 QSFP56 to 4×50G SFP56 Direct Attach Copper Cable (DAC), PVC, Passive, up to 3 m (10 ft)
Overview
The NS 200G PAM4 QSFP56 to 4×50G SFP56 Direct Attach Copper Cable (DAC) is a breakout copper solution for 200G-to-4×50G Ethernet connectivity in hyperscale data centers, HPC clusters, and cloud environments. It integrates one QSFP56 connector on one end and four SFP56 connectors on the other, enabling seamless 200G-to-50G breakout connections.
Constructed with twinax copper cable and a PVC jacket, this DAC offers ultra-low latency, reliable signal integrity, and significant cost savings compared to optical transceivers. The passive version supports lengths up to 3 m (10 ft) with negligible power draw. For extended needs, active copper variants reach up to 5 m (16 ft) while consuming ≤ 2 W.
