50G SFP56 Active Direct Attach Copper Twinax Cable (ACC/DAC), Active Twinax
Overview
The NSComm 50G SFP56 Active Direct Attach Copper (ACC/DAC) Twinax Cable is a cost-effective, low-latency interconnect solution for 50GbE short-reach links. With integrated SFP56 connectors on both ends, it delivers true plug-and-play deployment and helps avoid the cost and complexity of separate optical transceivers and fiber patch cords.
Built for modern 50G server and switch connections, this active twinax cable supports PAM4 modulation with a 53.125Gbps lane rate, enabling stable 50G performance in racks. It features low power consumption (0.5W) and includes an onboard EEPROM for identification by the host system-ideal for efficient deployment and asset management in data centers.
