Know before you buy
This cable is designed for short-reach, high-speed connections between network switches, servers, or storage devices within the same rack or adjacent racks in a data center.
No, this is a Direct Attach Copper (DAC) cable, meaning the QSFP28 connectors are integrated into the cable ends. It is ready for immediate plug-and-play installation without extra hardware.
While it is engineered for HPE Aruba environments, compatibility depends on the specific port requirements of your third-party hardware. Always verify that your equipment supports standard QSFP28 interfaces before installation.
Copper DAC cables are generally more cost-effective and energy-efficient for short-distance connections under 5 meters. They provide reliable 100G performance without the added complexity or power consumption of optical transceivers.
This cable supports a maximum data transfer rate of 100 Gbit/s, making it suitable for high-throughput enterprise network environments.
