BlueOptics 74764-1101 Compatible BlueLAN QSFP+ to 4x SFP+ Passive Direct Attach Copper Breakout Cable (DAC) - 1m

The BlueOptics 74764-1101 compatible BlueLAN QSFP+ to 4x SFP+ Passive Direct Attach Copper Breakout Cable (DAC) is a high-performance, cost-effective solution for 40 Gigabit Ethernet connectivity. Designed to break out a single QSFP+ port into four independent 10 Gigabit SFP+ links, this passive twinaxial copper cable is ideal for data center interconnects, rack-to-rack, and server-to-switch applications. With a length of 1 meter (3.3 feet), it provides a reliable, low-latency connection for adjacent racks or within the same rack.

Advantages

This breakout DAC cable offers significant advantages over traditional fiber optic transceivers and cabling. It consumes less power (passive design, no active components), reduces cost, and simplifies cable management. The integrated QSFP+ and SFP+ connectors eliminate the need for separate transceivers, saving space and reducing points of failure. It is hot-swappable and fully compliant with SFF-8436 (QSFP+) and SFF-8431 (SFP+) standards, ensuring interoperability with a wide range of networking equipment.

Suitable for

• Data center interconnects (DCI)
• Rack-to-rack and rack-to-server connectivity
• 40GbE to 4x10GbE breakout applications
• High-performance computing (HPC) clusters
• Enterprise and cloud networking environments

Recommendations

For optimal performance, ensure that your networking equipment supports QSFP+ and SFP+ interfaces and is configured for breakout mode. This cable is designed for short-reach, high-density connections within racks or between adjacent racks. For longer distances, consider active optical cables (AOC) or fiber optic transceivers.
