200G to 4x50G Breakout DAC Cable QSFP56 to SFP56

SVNK 200G QSFP56 Breakout Passive Direct Attach Copper (DAC) Cables

The SVNK 200G QSFP56 Breakout DAC cable series provides high-speed, cost-effective copper interconnect solutions designed to enable flexible 200G Ethernet and InfiniBand HDR port breakout architectures. These passive splitter cables are available in multiple configurations, including:

They convert a single 200G QSFP56 port carrying 4 × 50G PAM4 lanes into either four independent 50G SFP56 links or two independent 100G links, enabling efficient port utilization, scalable network design, and high-density deployments.

SVNK breakout DAC cables are constructed using precision high-frequency twinax copper conductors. With no active electronics, they deliver zero additional power consumption, ultra-low latency, minimal insertion loss, and excellent signal integrity, making them an ideal alternative to optical solutions for short-reach, high-speed interconnections.

These cables help data center operators increase port bandwidth, density, and configurability while significantly reducing capital and operational costs.

Fully compliant with QSFP56/SFP56 MSA, SFF-8636, and IEEE 802.3 standards, SVNK breakout DAC cables ensure seamless interoperability with leading switches, routers, and server platforms.
