BlueOptics QSFP28-4SFP28-DAC-3M Compatible BlueLAN Cable Breakout QSFP28 DAC 3m

The BlueOptics QSFP28-4SFP28-DAC-3M is a high-performance direct attach copper (DAC) breakout cable designed for 100 Gigabit Ethernet applications. This passive copper cable provides a cost-effective and low-power solution for short-range interconnects in data centers and high-performance computing environments. It breaks out a single QSFP28 port into four SFP28 ports, enabling flexible network architecture.

Advantages

This DAC breakout cable offers several key benefits: low power consumption (<0.5W), hot-swappable design for easy installation, and full compatibility with BlueLAN and industry-standard QSFP28/SFP28 ports. The 26 AWG construction ensures reliable signal integrity over 3 meters, while the PVC jacket provides durability.

Suitable for

• 100 Gigabit Ethernet connections
