40G to 4x10G Breakout DAC Cable QSFP+ to 4xSFP+

SVNK 40G QSFP+ to 4×10G SFP+/XFP Breakout DAC Cable

The SVNK 40G QSFP+ Breakout Direct Attach Copper (DAC) cable is a cost-effective, low-power interconnect solution designed to break out a single 40G QSFP+ port into four independent 10G ports. It is available in configurations of QSFP+ to 4×SFP+ or QSFP+ to 4×XFP, enabling flexible connectivity between switches, servers, storage systems, and other network equipment over short distances.

These passive copper breakout assemblies support 40G Ethernet (40GBASE-CR4) on the QSFP+ side and 10GBASE-CR links on the SFP+/XFP side. Fully compliant with QSFP+ MSA standards (SFF-8436, SFF-8431) and IEEE 802.3ba, the cable ensures seamless interoperability with leading networking platforms.

SVNK breakout DAC cables enable high port density, ultra-low latency, minimal power consumption, and reduced total cost of ownership, making them ideal for high-density rack environments where short-reach, high-speed connections are required.
