Optical fiber communication, also known as optical fiber communication
Optical fiber communication, also known as optical fiber communication, refers to a way of transmitting information by means of light and optical fiber. A kind of cable communication. The light can carry information after being altered. Since the 1980s, optical fiber communication systems have had a revolutionary impact on the telecommunications industry and played a very important role in the digital age. Optical fiber communication has the advantages of large transmission capacity, good secrecy and so on. Optical fiber communication has become the most important way of wired communication nowadays. The information that needs to be transmitted is input into the transmitter at the sending end, and the information is superimposed or modulated to the carrier carrier of the information signal, and then the modulated carrier is transmitted through the transmission medium to the distant receiver, and the original information is demodulated by the receiver.
