NSComm 100G QSFP28 to 2 x 50G QSFP28 Ethernet Active Direct Attach Copper Breakout Cable up to 9m(29ft)
100G QSFP28 to 2 x 50G QSFP28 Active Direct Attach Copper Breakout Cable (ACC/DAC), Active Twinax
Overview
The NSComm 100G QSFP28 to 250G QSFP28 Active Direct Attach Copper (ACC/DAC) Breakout Cable provides a simple, cost-effective way to split one 100G QSFP28 port into two 50G links for short-reach connectivity. With integrated active twinax copper, it enables plug-and-play deployment and reduces the need for separate optics and fiber patching in rack environments.
Built for reliable in-rack performance, this breakout ACC/DAC supports stable 100G-to-250G Ethernet interoperability with power consumption up to 1.5W and cleaner routing via a 27.5mm minimum bend radius. It is compliant with QSFP28 MSA and key SFF standards including SFF-8665 / SFF-8636 / SFF-8679, making it suitable for modern 50G server and switch deployments.
Compatibility Options (Coding)
NSComm provides multiple vendor coding options (selectable on the product page) to match your switch, router, NIC, server, or storage platform across mainstream ecosystems.
Not sure which coding you need? Contact our certified engineers and we'll help confirm the right option for your exact model.
Use Scenarios / Applications
-
ToR port breakout to 50G servers: use one 100G QSFP28 port to connect two 50G NIC servers within the rack.
-
Leaf access expansion: convert 100G switch ports into dual 50G downlinks for phased 25G/50G upgrades.
-
Switch-to-switch short links: dual 50G connections between switches for compact pods and rack-level fabrics.
-
HPC / cluster racks: cost-effective short-reach cabling for high-density compute racks using 100G and 50G ports.
