With the rapid development of the network, the data center has been facing the challenges of high bandwidth, high reliability and low latency, and it needs a low-cost and high-speed interconnection solution with high efficiency. In short distance transmission, compared with the combination of optical module and fiber jumper, DAC high-speed cable has the advantages of low power consumption, low cost and convenient use, which is widely used in the Internet data center.
Advantages of DAC high speed cable compared with optical module
energy saving and environmental protection: DAC high-speed cable adopts copper core with good heat dissipation effect.
low power consumption: the power consumption of DAC high-speed cable is low, generally speaking, the power consumption of optical module is more than 1W, but the power consumption of DAC high-speed cable is generally less than 0.5W.
low cost: the optical components of DAC high-speed cable do not have optical lasers and other electronic components, which can effectively save manufacturing costs. The price of copper cable is much lower than that of optical fiber. During wiring, DAC high-speed cable can effectively save the use of optical fiber, so as to achieve the effect of low cost.
The optical devices on both ends of the DAC high-speed cable seem to be the same as the optical modules, but in fact, it is not a real optical module, because it has no optical laser and no electronic components, so it can only transmit electrical signals, not optical signals.
