Product Overview

The Amphenol NDAQGF-0002 is a passive direct-attach copper (DAC) breakout cable assembly that connects a single QSFP28 (100 Gbps) port to four SFP28 (25 Gbps) ports. It is commonly used to “break out” a 100 GbE link into four independent 25 GbE links, enabling flexible interconnects between high-density switches, servers, or storage devices in short-reach data-center environments.
