The Active Copper Cable Multi-Source Agreement (ACC-MSA) has been formed by thirteen global leaders in networking, semiconductors, and cabling, including AMD and Cisco. The consortium aims to define specifications to improve power efficiency, cost, and latency of high-speed copper interconnects.

The initial focus is on optimized copper interconnects with integrated linear equalizers, setting standards for electrical, firmware, and testing requirements to ensure compatibility among multiple vendors. This initiative is expected to significantly extend the reach of copper cables while decreasing thickness and power consumption.
