BlueLAN R8M56A-BL cavo DAC Breakout 400G QSFP-DD a 4x QSFP56 2m compatibile HPE

The BlueLAN R8M56A-BL is a high-performance passive Direct Attach Breakout Cable (DAC) designed for 400G QSFP-DD to 4x100G QSFP56 connectivity. This cable enables seamless breakout from a single 400G port to four independent 100G ports, ideal for high-density data center and HPC environments. It is fully compatible with HPE M-Series switches and servers, offering a cost-effective and reliable solution for high-speed networking.

Advantages

This breakout cable simplifies network architecture by reducing the number of cables and transceivers needed. It supports aggregate data rates of 400 Gbps, with each of the four QSFP56 lanes delivering 100 Gbps. The passive design ensures low power consumption and high reliability, while the 2-meter length provides flexibility in rack installations. HPE compatibility guarantees seamless integration with existing infrastructure.

Suitable for

• Data center interconnects requiring high-density 400G to 100G breakout
