- Overview of DAC High-Speed Cables
DAC (Direct Attach Cable) high-speed cables are modules with fixed connectors at both ends, commonly used for short-distance high-speed connections. DAC cables use copper wires to transmit electrical signals and do not involve optical-electrical conversion, meaning they do not require optical components. They are generally suitable for short-distance connections and stacking applications. DAC high-speed cables are widely used in data centers, high-performance computers, and large-capacity storage devices.
- Difference Between DAC High-Speed Cables and AOC Active Optical Cables
DAC high-speed cables and AOC active optical cables are both high-speed cables used for interconnecting devices or stacking them. Typically, DAC passive cables are chosen for short-distance device stacking, making DAC cables a type of stacking cable. For longer-distance device connections, AOC active optical cables are generally used, offering greater transmission distance and more stable performance.
There are notable differences between DAC and AOC cables. Firstly, DAC cables are direct-attach copper cables (like DAC passive cables), with a relatively short transmission distance. In contrast, AOC cables contain active components, such as optical-electrical converters, which enable them to support longer distances, reaching up to 100 meters or more. Secondly, regarding power consumption, DAC cables have very low power consumption due to the absence of active components, while AOC cables have some power consumption due to the active modules. Furthermore, in terms of cost, DAC cables are typically more affordable, whereas AOC cables are more expensive due to their technical complexity.
- What Type of Cable is Used for DAC High-Speed Cables? How Does It Differ from Ethernet Cables?
DAC high-speed cables typically use special copper cables, which are different from Ethernet cables. Ethernet cables primarily consist of copper twisted pairs that transmit data via electrical signals, with a shorter transmission distance (usually under 100 meters) and are more susceptible to electromagnetic interference. In contrast, the copper cables in DAC high-speed cables are designed for high-speed, high-bandwidth transmission. These cables have advantages such as faster transmission speed, higher bandwidth, and better resistance to electromagnetic interference. The maximum transmission distance for DAC cables is typically up to 7 meters.
