The active component of light refers to "the component responsible for the generation and reception of optical signals, which is related to the conversion of photoelectric energy." The generation of optical signals usually refers to the conversion of electrical energy into light energy; the reception of optical signals usually refers to the conversion of optical energy into electrical energy. Since the processing and operation of general data uses computers, the computer uses electrical signals to process data. Therefore, when we want to transmit data to the optical network, we must first convert the electrical signals into optical signals, as shown in Figure 5. The function of the transmitter "Transmitter" is to convert the electrical signal into an optical signal. We can imagine that it converts the "0" and "1" of the electrical signal into the "dark" and "light" of the optical signal. After the optical signal has passed hundreds of kilometers of transmission in the optical fiber, it reaches the receiving end. At this time, the optical signal must be converted into an electrical signal. As shown in Figure 5, the receiving end is called the "receiver" function. It is to convert the optical signal into a telecommunication signal. We can imagine that it converts the "dark" and "bright" of the optical signal into the "0" and "1" of the electrical signal, and then hands it to the computer for processing and calculation. This is The basic principles of working with fiber optic networks and computers.
