BlueLAN 40G QSFP+ naar 4x10G SFP+ passieve Direct Attach breakout-kabel, 2m, AWG30, NVIDIA-compatibel (MCC1V30A-002-BL)

In high-density data centers and HPC clusters, network engineers use the BlueLAN MCC1V30A-002-BL to connect a 40G QSFP+ port to four separate 10G SFP+ ports. This 2-meter passive direct attach breakout cable splits a single 40GBASE-CR4 link into four 10GBASE-CR channels, eliminating the need for separate transceivers and reducing cabling complexity.

Why choose it

Passive DAC cables consume no power and introduce near-zero latency, making them ideal for short-reach interconnects within racks or adjacent racks. The breakout design allows you to connect a 40G switch port to four 10G servers or storage devices using a single cable, saving space and simplifying cable management. The 30 AWG copper twinax construction offers a balance of flexibility and signal integrity for 2-meter runs.

Ideal use cases

• Linking 40G QSFP+ switch ports to multiple 10G SFP+ servers or storage arrays.
• High-performance computing clusters requiring low-latency, high-bandwidth interconnects.
• Data center top-of-rack to end-of-row aggregation.
• Environments where optical transceivers are cost-prohibitive for short distances.

Good to know

This cable is compatible with NVIDIA MCC1V30A-002 specifications and is hot-pluggable, allowing for easy installation and replacement without downtime. It supports Ethernet protocol and is designed for passive operation, requiring no additional power source.
