400G QSFP112 to QSFP112 Active Direct Attach Copper Twinax Cable (ACC/DAC), Active Twinax
Overview
The NSComm 400G QSFP112 Active Direct Attach Copper (ACC/DAC) Twinax Cable delivers a cost-effective, low-latency solution for 400GbE short-reach interconnects. With integrated QSFP112 connectors on both ends, it enables plug-and-play deployment and reduces the cost and complexity of separate optical transceivers and fiber patch cords for short links.
Built for high-density rack environments, this active twinax cable supports a retimed 400GAUI-4 electrical interface (4106.25G PAM4) for stable 400G performance, with max power consumption 1.5W per end and a 35mm minimum bend radius for cleaner routing. It is compliant with QSFP112 MSA and SFF-8636, making it suitable for compact 400G Ethernet fabrics in data centers and telecom equipment rooms.
