BlueLAN Amphenol NDAQGF-0002 Compatible Breakout Direct Attach Cable (DAC) Passive 100 Gigabit to 4x25 Gigabit Twinaxial Copper, QSFP28 to 4xSFP28, for Rack and Adjacent Rack Connections

The BlueLAN Amphenol NDAQGF-0002 compatible Breakout Direct Attach Cable (DAC) is a high-performance passive twinaxial copper cable designed for 100 Gigabit Ethernet applications. It provides a cost-effective and low-latency solution for connecting network hardware within racks and across adjacent racks, converting a single QSFP28 port into four SFP28 ports.

Advantages

This breakout cable offers significant advantages over active optical cables, including lower power consumption (<0.5W), reduced cost, and high reliability. Its passive design ensures zero power draw from the host device, making it ideal for energy-efficient data centers. The cable is hot-pluggable and compliant with industry standards, ensuring seamless integration with existing infrastructure.
