40G QSFP+ to 4 x 10G SFP+ Active Direct Attach Copper Breakout Cable (ACC/DAC), Active Twinax
Overview
The NSComm 40G QSFP+ to 410G SFP+ Active Direct Attach Copper (ACC/DAC) Breakout Cable provides a simple, cost-effective way to break out one 40G QSFP+ port into four 10G SFP+ links. With an integrated active twinax copper design, it delivers plug-and-play deployment and avoids the cost and complexity of optical transceivers and fiber patch cords for short-reach connections.
This breakout ACC/DAC supports stable 40G-to-410G interoperability with power consumption up to 1.8W and flexible routing via a 33mm minimum bend radius. It is compliant with key SFP+ and QSFP+ MSA/SFF standards, making it ideal for data center and enterprise rack interconnects.
Compatibility Options (Coding)
NSComm provides multiple vendor coding options (selectable on the product page) to match your switch, router, NIC, server, or storage platform.

Use Scenarios / Applications
-
ToR port breakout to servers: convert a 40G QSFP+ downlink into four 10G SFP+ server connections in the same rack.
-
Access switch expansion: use one 40G port to feed multiple 10G edge devices without deploying optics.
-
Mixed-speed migration: keep 40G uplinks while extending 10G access during phased upgrades.
-
Rack interconnects: ideal for switch/router/server/storage connections within racks or adjacent racks, including lab and HPC rack builds.
