NSComm 100G QSFP28 to 4 x 25G SFP28 Ethernet Active Direct Attach Copper Breakout Cable up to 9m(29ft)
100G QSFP28 to 4 x 25G SFP28 Active Direct Attach Copper Breakout Cable (ACC/DAC), Active Twinax
Overview
The NSComm 100G QSFP28 to 425G SFP28 Active Direct Attach Copper (ACC/DAC) Breakout Cable is a cost-effective, low-latency solution that lets you split one 100G QSFP28 port into four 25G 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 patching in rack environments.
Designed for high-density data center cabling, this breakout ACC/DAC supports stable 100G-to-425G Ethernet interoperability with power consumption up to 1.8W and clean routing thanks to a 33mm minimum bend radius. It complies with QSFP28 MSA and SFP28 MSA, plus key SFF standards including SFF-8665 / SFF-8679 / SFF-8472 / SFF-8402, making it a reliable choice for 25G server access and phased 100G upgrades.
Compatibility Options (Coding)
NSComm provides multiple vendor coding options (selectable on the product page) to match your switch, router, NIC, server, storage, or security 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 breakout to 25G servers: use one 100G QSFP28 port to connect four 25G NIC servers within the rack.
-
Leaf access downlinks: convert 100G switch ports into multiple 25G links for server rows and rack pods.
-
Phased migration (10G/25G 100G): keep 100G-capable switches while maintaining 25G access during upgrades.
-
HPC / cluster racks: cost-efficient short-reach cabling for high-density compute racks using 100G uplinks and 25G node links.
