BlueOptics Dell 331-8151 BlueLAN Passives 40GBASE-CR4 QSFP a 4x10GBASE-CR SFP+ Cable Direct Attach Breakout, 3 m

The BlueOptics Dell 331-8151 BlueLAN passive 40GBASE-CR4 QSFP to 4x10GBASE-CR SFP+ Direct Attach Breakout Cable is a high-performance copper cable designed for data center and high-performance computing environments. It provides a cost-effective solution for connecting 40G QSFP ports to four 10G SFP+ ports, enabling seamless network upgrades and flexible connectivity.

Advantages

This breakout cable simplifies cabling by replacing four separate 10G cables with a single 40G to 4x10G assembly, reducing clutter and improving airflow. Its passive design ensures low power consumption and zero latency, making it ideal for short-range, high-speed interconnects. The cable is fully compatible with Dell 331-8151 equipment and other standard QSFP/SFP+ interfaces.

Suitable for

• Data center interconnects between 40G switches and 10G servers or storage
• High-performance computing (HPC) clusters requiring high-density cabling
