What is AOC? Active Optical Cable, referred as AOC. There are two modules at both ends of the AOC, and a section of optical fiber in the middle (referred to the following picture). There are optical transmitters and optical receivers on the circuit boards of the modules at both ends of the AOC. Their function is to convert electrical signals into optical signals at the transmitting end , transmitting them into the optical fiber, and then convert the optical signals into electrical signals at the receiving end. Because it is optical signal transmission, compared with DAC, the transmission distance is longer, but because it involves photoelectric conversion, the design and processing technology are more complicated, the cost and power consumption are also higher.
