800G OSFP to OSFP Direct Attach Copper Cable (DAC), PVC, Passive, up to 3 m (10 ft)

Overview

The NSComm 800G OSFP to OSFP Direct Attach Copper Cable (DAC) is a next-generation, high-speed interconnect solution engineered for 800 Gigabit Ethernet applications in AI/ML clusters, hyperscale data centers, and HPC environments. With integrated OSFP connectors on both ends, this DAC eliminates the need for costly optical transceivers, offering a plug-and-play, ultra-low latency option for short-distance connectivity.

Constructed with twinax copper cable and a durable PVC jacket, the passive DAC supports links up to 3 m (10 ft) with near-zero power consumption. For extended reach, active copper variants provide up to 5 m (16 ft) at ≤ 6 W per end. It ensures stable signal integrity, excellent EMI performance, and minimal latency, making it ideal for rack-to-rack connections in dense deployments.
