Product Overview
The T DQ4CNL N00 is a 100G QSFP28 to 4x 25G SFP28 passive direct attach copper (DAC) breakout cable, optimized for short-reach, high-density data center interconnects. This high-performance, cost-effective solution enables 1-to-4 breakout connectivity from a single 100G QSFP28 port to four individual 25G SFP28 ports. Designed with low-latency and zero power consumption, it is ideal for Top-of-Rack (ToR) switch-to-server, network aggregation, and high-performance computing (HPC) applications.
