200G QSFP56 to QSFP56 Active Direct Attach Copper Twinax Cable (ACC/DAC), Active Twinax
Overview
The NSComm 200G QSFP56 Active Direct Attach Copper (ACC/DAC) Twinax Cable is a high-speed, cost-effective interconnect solution for 200GbE short-reach links in modern data centers. With integrated QSFP56 connectors on both ends, it enables plug-and-play deployment and reduces the need for separate optical transceivers and fiber patch cords for short distances.
For today's mainstream 200G deployments, NVIDIA Ethernet environments are especially common. NSComm supports NVIDIA (Ethernet) coding options on the product page, making it easy to match typical NVIDIA-based switching and server platforms-while still offering selectable coding for other major vendors when needed. Built-in retiming silicon (Macom) delivers stable performance with max power consumption 1.5W per end, and the cable remains easy to route with a 33mm minimum bend radius.
Compatibility Options (Coding) - NVIDIA Focus, Multi-Vendor Ready
-
Recommended option: choose NVIDIA (Ethernet) coding for mainstream NVIDIA Ethernet switch/NIC environments.
-
Also available: selectable coding options for other major platforms (choose the matching option on the product page).

Use Scenarios / Applications
-
NVIDIA Ethernet rack interconnects: connect 200G QSFP56 ports between Ethernet switches and servers/NICs for short in-rack links.
-
Leaf/ToR fabric links (short reach): 200G connections between ToR/leaf switches within the rack or adjacent racks in compact pods.
-
Server/storage connectivity: short 200G links for high-throughput storage or compute nodes where low latency and simple cabling matter.
-
Fast cluster expansion: add 200G links quickly without deploying optics for short-distance runs.
