Know before you buy
This cable is designed for high-speed, short-distance connections within a data center, such as linking switches to other switches or connecting servers to top-of-rack switches.
While this cable is specifically optimized for the Aruba 8400X Switch Series, compatibility with other hardware depends on the specific port requirements and vendor-locking policies of your other networking devices.
Direct-attach copper (DAC) cables are a more cost-effective and power-efficient solution for short-reach connections. They come as a single, integrated unit, eliminating the need for separate transceivers and reducing overall installation complexity.
The cable is engineered for 100 Gbps performance. While it may technically link at lower speeds depending on the host port's auto-negotiation capabilities, it is intended specifically for high-bandwidth 100G environments.
Because this is a passive copper cable, it is limited to a 3-meter length to maintain signal integrity. If your equipment racks are spaced further apart than 3 meters, you will need to switch to active optical cables (AOC) or traditional fiber optics.
