200G PAM4 QSFP56 to QSFP56 Direct Attach Copper Cable (DAC), Passive, up to 3 m (10 ft)
Overview
The NS 200G PAM4 QSFP56 to QSFP56 Direct Attach Copper Cable (DAC) is a high-performance, short-reach interconnect designed for 200 Gigabit Ethernet applications in hyperscale data centers and HPC clusters.
Built with twinax copper cable and factory-terminated QSFP56 connectors, it delivers 200 Gbps bandwidth across 4×50 Gbps PAM4 lanes, offering ultra-low latency and cost-effective performance.
The passive DAC supports lengths up to 3 m (10 ft) with virtually zero power consumption. For deployments requiring longer reach, active DAC options extend distances up to 5 m (16 ft) while consuming less than 2 W. This makes it an ideal choice for top-of-rack (ToR) and middle-of-row (MoR) connectivity where cost and efficiency are critical.
Compatible Brands
The NS 200G QSFP56 DAC is interoperability-tested with devices from Cisco, Huawei, Juniper, Arista, Dell and Nvidia.
