The Active Optical Cable 400G QSFP-DD to 2×QSFP56 is designed to deliver flexible, high-speed optical connectivity for modern data center environments. Supporting eight 53.125Gbps channels, this AOC enables efficient breakout from a 400G QSFP-DD port to dual 200G QSFP56 connections, providing scalable bandwidth deployment for Ethernet and InfiniBand networks.
Built with VCSEL transmitters and PIN receivers, the cable offers reliable optical performance and strong signal integrity over distances ranging from 1 to 100 meters. With commercial temperature operation and optimized power consumption—up to 10W per end at 400G and 5W per end at 200G—this solution is well suited for dense, high-performance data center architectures requiring flexibility, reliability, and ease of deployment.
