BlueOptics QSFP28-4SFP28-DAC-1M Compatible BlueLAN QSFP28 DAC Breakout Cable 1m

The BlueOptics QSFP28-4SFP28-DAC-1M is a high-performance direct attach copper (DAC) breakout cable designed for 100 Gigabit Ethernet networks. This passive copper cable connects a QSFP28 port to four SFP28 ports, providing a cost-effective and reliable solution for short-range interconnects within data centers and enterprise networks. With a length of 1 meter, it is ideal for top-of-rack to server connections.

Advantages

This DAC breakout cable offers low power consumption, high signal integrity, and hot-swappable functionality. It eliminates the need for separate transceivers and fiber cabling, reducing cost and complexity. The passive design ensures zero power consumption at the cable ends, making it an energy-efficient choice.
