Advantage&disadvantage of Direct Attach Cable DAC
Advantages: 1. High-performance: It is suitable for short-distance wiring of data centers, and has a wide range of applications.
2. Energy-saving and environmental protection: The internal material of the high-speed cable is a copper core. The natural heat dissipation effect of the copper cable is good, and it is energy-saving and environmentally-friendly.
3, Low power consumption: high-speed cable power consumption is low. Since the passive cable does not require a power supply, the power consumption is almost zero; the power consumption of the active cable is generally around 440 mW.
4. Low cost: The price of copper cables is much lower than that of optical fibers. Therefore, the use of high-speed cables can greatly reduce the wiring cost of the entire data center.
Disadvantages of Direct Attach Cable:
1: The transmission distance is short, heavy, bulky and difficult to manage.
2: susceptible to electromagnetic interference, for example, It may cause problems such as poor response and degradation.
