800G QSFP-DD to QSFP-DD Active Direct Attach Copper Twinax Cable (ACC/DAC), Active DAC (ACC)
Overview
The NSComm 800G QSFP-DD Active Direct Attach Copper (ACC/DAC) Twinax Cable is a high-speed, cost-effective alternative to fiber optics for 800G Ethernet short-reach interconnects. With integrated QSFP-DD connectors on both ends, it provides plug-and-play deployment and helps reduce the cost and operational complexity of separate optical modules and fiber patch cords for short distances.
Built for next-generation high-density switching, this active DAC contains 16 high-speed copper pairs supporting up to 100Gb/s per pair and uses PAM4 signaling to enable stable 800G performance in racks. It keeps power efficient with 1.2W consumption and supports tidy routing with a 34.5mm minimum bend radius. Compliant with IEEE 802.3ck and the QSFP-DD MSA (Rev. 5.0) ecosystem, it's a practical choice for modern 800G data center builds.
Compatibility Options (Coding)
NSComm provides multi-vendor coding options (selectable on the product page) to match your switch, router, NIC, server, or storage platform.

Use Scenarios / Applications
-
Leaf-spine / core short links (800G): interconnect high-capacity switches inside a rack row for compact 800G fabrics.
-
ToR uplinks and rack aggregation: connect ToR switches to leaf/aggregation switches for high-density racks and fast scaling.
-
AI / HPC rack networking (Ethernet): short in-rack links where bandwidth, latency, and port density are critical.
-
High-bandwidth upgrades: deploy 800G switching while keeping cabling simple for short distances.
