BlueOptics HPE 834973-B25 BlueLAN SC282801L3M26 QSFP28 Direct Attach Copper Cable, 100GBASE-CR4, 26AWG, 3 Meter, Black

The BlueOptics HPE 834973-B25 BlueLAN SC282801L3M26 QSFP28 Direct Attach Copper (DAC) Cable is a high-performance, passive copper cable designed for 100 Gigabit Ethernet (100GBASE-CR4) and InfiniBand EDR applications. Engineered for data centers and high-performance computing (HPC) environments, this cable provides reliable, low-latency connectivity with minimal power consumption. It is compatible with HPE (Hewlett Packard Enterprise) equipment and meets the HPE 834973-B25 part number specification.

Advantages

This DAC cable offers a cost-effective and energy-efficient solution for short-range high-speed interconnects. With a length of 3 meters and 26 AWG wire gauge, it provides flexibility in rack and cabinet setups while maintaining signal integrity. The passive design ensures zero power consumption beyond the negligible <0.5W per end, reducing overall system power draw. Its robust PVC jacket and compliance with RoHS, CE, and FCC standards guarantee durability and regulatory adherence.

Suitable for

• Data center top-of-rack (ToR) to server connections
