NSComm NVIDIA/Mellanox Compatible 400G QSFP-DD to 4 x 100G QSFP28 Ethernet Active Electrical Breakout Cable 3m(10ft)
400G QSFP-DD to 4¡Á100G QSFP28 Ethernet Active Electrical Breakout Cable (AEC)
Overview
The NSComm 400G QSFP-DD to 4¡Á100G QSFP28 Active Electrical Cable (AEC) Breakout is a high-performance copper fanout solution that lets you split one 400G QSFP-DD port into four 100G QSFP28 links for short-reach deployments. Unlike passive copper, AEC uses active signal conditioning to improve PAM4 link stability, making it a strong choice when you need reliable high-speed breakouts without moving to optics.
Because NVIDIA Ethernet is the most common ecosystem in modern AI and high-density data centers, this breakout AEC supports NVIDIA (ETH) coding options on the product page-recommended for NVIDIA switch/NIC environments-while still allowing selectable options for broader multi-vendor use. It supports 400G to 4¡Á100G interoperability and uses a built-in gearbox to convert 8¡Á53G PAM4 into four 4¡Á25G NRZ lanes, enabling practical 100G QSFP28 fanout. With a 26.5mm minimum bend radius, it helps keep rack cabling clean and manageable.
Compatibility Options (Coding) - NVIDIA Focus, Multi-Vendor Ready
-
Recommended option: choose NVIDIA (ETH) coding for mainstream NVIDIA Ethernet switch/NIC environments.
-
Also available: selectable coding options for other platforms (choose the matching option on the product page).
Need help confirming the right coding? Contact our certified engineers for quick validation.
Use Scenarios / Applications
-
400G switch port to four 100G servers/NICs: ideal for ToR/leaf switches breaking out to multiple 100G endpoints in the rack.
-
Leaf access fanout: use one 400G uplink port to feed four 100G downlinks for rack pods and edge rows.
-
Phased upgrades: deploy 400G switching now while keeping existing 100G QSFP28 devices during migration.
-
When passive fanout is unstable: choose AEC when you need better signal integrity for copper fanout at high speeds.
