800G ACC Active Copper Cable Overview

C-LIGHT 800G ACC active copper cables are designed for ultra-high-speed interconnects in AI data centers, high-performance computing systems, cloud infrastructure, telecommunications, and other bandwidth-intensive network environments. The active copper architecture combines high-speed electrical transmission with integrated signal conditioning to support demanding 800G connectivity requirements.

Unlike conventional passive DAC solutions, the 800G ACC uses active electrical technology to extend the practical reach of high-bandwidth copper interconnects while maintaining a compact cable architecture. This makes ACC suitable for applications where the required connection exceeds the practical limitations of passive copper cabling.

C-LIGHT provides multiple 800G ACC configurations, including 800G QSFP-DD to QSFP-DD, 800G OSFP112 to QSFP-DD, OSFP112 to OSFP112, and breakout configurations for 400G and 200G interfaces.

The product family supports cable lengths from 0.5m to 5m depending on the configuration, with multiple connector constructions and copper gauges available for different equipment layouts.
