BlueLAN HPE R9F93A Compatible SFP28 Direct Attach Cable (DAC) - Passive 25 Gigabit Twinaxial Copper, 1m

The BlueLAN HPE R9F93A compatible Direct Attach Cable (DAC) is a high-performance, passive 25 Gigabit Twinaxial Copper cable designed for reliable, low-latency connections in data centers and enterprise networks. With SFP28 connectors on both ends, this 1-meter cable is ideal for connecting servers, switches, and storage within racks or across adjacent racks, ensuring seamless 25GbE connectivity.

Advantages

This passive DAC cable offers zero power consumption, eliminating the need for external power sources and reducing overall energy costs. Its twinaxial copper construction provides excellent signal integrity and low electromagnetic interference, making it a cost-effective alternative to active optical cables for short-range links. The hot-swappable SFP28 connectors enable easy installation and maintenance without network downtime.

Suitable for

• Connecting HPE Aruba switches and servers with SFP28 ports
• Rack-to-rack and server-to-switch interconnects in data centers
