BlueLAN HPE R9F78A Compatible QSFP28 Direct Attach Cable (DAC) - Passive 100G Twinaxial Copper, 1m

The BlueLAN HPE R9F78A compatible Direct Attach Cable (DAC) is a high-performance, passive 100 Gigabit Twinaxial Copper cable designed for reliable, low-latency connections in data centers and enterprise networks. With QSFP28 connectors on both ends, this cable provides a cost-effective solution for short-range interconnects within racks and across adjacent racks.

Advantages

This DAC cable offers exceptional signal integrity and low power consumption (<0.1W), making it an energy-efficient choice for high-density environments. Its passive design ensures zero latency and no additional power requirements, while the twinaxial copper construction delivers robust performance for 100GBASE-CR4 and InfiniBand applications. The cable is hot-pluggable and fully compatible with HPE R9F78A interfaces, ensuring seamless integration.
