200G QSFP56 to 2 x 100G QSFP56 Ethernet Active Direct Attach Copper Breakout Cable (ACC/DAC), Active Twinax
Overview
The NSComm 200G QSFP56 to 2 x 100G QSFP56 Active Direct Attach Copper (ACC/DAC) Breakout Cable is a high-speed, cost-effective way to split one 200G QSFP56 port into two 100G links for short-reach connectivity. With integrated active twinax copper and factory-terminated connectors, it delivers plug-and-play deployment and reduces the need for separate optical modules and fiber patch cords in rack environments.
In today's mainstream 200G/100G deployments, NVIDIA Ethernet ecosystems are widely used for data center switching and GPU/compute clusters. NSComm supports NVIDIA (Ethernet) coding options on the product page to match typical NVIDIA platforms, while also providing selectable coding for other major vendors.
This breakout cable is compliant with IEEE 802.3cd and key QSFP standards, and supports stable interoperability with power consumption up to 1.5W and a 27.5mm minimum bend radius for cleaner rack routing.
Compatibility Options (Coding) - NVIDIA Focus, Multi-Vendor Ready
-
Recommended option: choose NVIDIA (Ethernet) coding for mainstream NVIDIA switch/NIC environments.
-
Also available: selectable coding options for other major platforms (choose the matching option on the product page).
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
-
NVIDIA Ethernet port breakout: split a 200G QSFP56 port into two 100G QSFP56 links for rack-level switching and server connectivity.
-
ToR/Leaf fabric expansion: use one 200G port to feed two 100G downlinks for compact pods and phased upgrades.
-
Switch-to-switch / switch-to-server short links: connect switches to switches, servers, or storage inside the rack or nearby racks without optics.
-
Data center & telecom equipment rooms: cost-effective close-range interconnects where fast deployment and predictable performance matter.
