Overview
The NSComm 400G QSFP-DD Active Direct Attach Copper (ACC/DAC) Twinax Cable is a cost-effective, low-latency interconnect solution for 400GbE short-reach links in modern data centers and telecom equipment rooms. With integrated QSFP-DD connectors on both ends, it delivers true plug-and-play deployment and reduces the cost and operational complexity of separate optical transceivers and fiber patch cords for short connections.
Designed for stable high-speed signaling, this active twinax cable features built-in Macom retiming silicon and supports a retimed 400GAUI-8 electrical interface (853.125G PAM4) for consistent 400G performance.
It keeps power predictable with max power consumption 2.5W per end and supports structured rack cabling with an 80mm minimum bend radius. Compliant with QSFP-DD MSA and SFF-8636, it is a reliable option for close-range 400G Ethernet fabrics.

Use Scenarios / Applications
-
Leaf-spine short links (400G): interconnect leaf and spine switches for compact 400G fabrics where devices are in the same rack row.
-
ToR uplinks and rack aggregation: connect ToR switches to leaf/aggregation switches with short 400G links for high-density racks.
-
Telecom / data center equipment rooms: cost-effective close-range 400G interconnects where fast deployment and predictable power matter.
-
LAN/SAN high-speed interconnects: short 400G Ethernet links for high-throughput network and storage environments.
