BlueOptics QSFP28-DAC-2M-RW-BL cavo InfiniBand nero

High-density data centers and HPC clusters need reliable, low-latency links between QSFP28 ports. The BlueOptics QSFP28-DAC-2M-RW-BL is a 2-meter Direct Attach Copper (DAC) cable that connects two QSFP28 interfaces without separate transceivers, reducing cost and power consumption while supporting InfiniBand EDR and 100G Ethernet.

Who is it for

Network engineers and data center operators deploying 100G InfiniBand or Ethernet fabrics over short distances. Ideal for top-of-rack to server connections, storage interconnects, and HPC cluster nodes where passive copper provides the best price-performance.
