40G QSFP+ to QSFP+ Active Direct Attach Copper Cable (ACC/DAC), Active Twinax
Overview
The NSComm 40G QSFP+ Active Direct Attach Copper (ACC/DAC) Twinax Cable is a high-speed, cost-effective interconnect for 40GbE short-reach links. With integrated QSFP+ connectors on both ends, it delivers plug-and-play deployment and avoids the cost and complexity of separate optical transceivers and fiber patch cords.
Engineered for stable data center performance, this active twinax cable supports consistent throughput with low power consumption (up to 1.5W) and tidy rack routing thanks to a 40mm minimum bend radius. It is compliant with IEEE 802.3ba and QSFP MSA, making it a dependable choice for short 40G connections within a rack or between adjacent racks.
Compatibility Options (Coding)
NSComm provides multiple vendor coding options (selectable on the product page) to match your switch, router, NIC, or server requirements across major platforms.

Use Scenarios / Applications
-
ToR/Leaf interconnects: connect Top-of-Rack or leaf switches for short 40G uplinks inside the rack.
-
Switch-to-switch aggregation links: quick 40G connections between access and aggregation layers during upgrades or expansion.
-
High-speed server/storage attachment: short 40G links where low latency and simple cabling are required.
-
Mixed-protocol short links: supports common 40GbE and data center short-reach interconnect use cases.
