BlueLAN QSFP28 to 4x SFP28 Passive Breakout Direct Attach Cable (DAC) 1.5m - Compatible with Siemon Q4S28P301.5-01P

The BlueLAN QSFP28 to 4x SFP28 Passive Breakout Direct Attach Cable (DAC) is a high-performance, cost-effective solution designed to connect 100 Gigabit QSFP28 ports to four 25 Gigabit SFP28 ports. This cable is fully compatible with Siemon Q4S28P301.5-01P equipment and is ideal for data center and high-performance computing environments where high-density, low-latency interconnects are required.

Advantages

This passive breakout DAC offers a reliable and energy-efficient alternative to active optical cables, consuming less than 0.5W of power. The twinaxial copper construction ensures excellent signal integrity over the 1.5-meter length, making it perfect for in-rack and adjacent-rack connections. Hot-swappable connectors allow for easy installation and maintenance without disrupting network operations.

Suitable for

• Data center top-of-rack to server connections
• High-performance computing (HPC) clusters
• Network aggregation and core switching
• Storage area networks (SAN)
