Information is sent through light in fiber optic communication technology, which is also a low-loss, low-interference, high-bandwidth, and high-speed communication technology. Optical communication uses optical fiber as a transmission medium to convert information into optical signals for transmission. Its advantages are strong anti-interference ability, long transmission distance, and fast transmission speed.1. Basic principlesFiber optic communication uses light waves as information carriers and optical fiber as a transmission medium. The transmitting end of the fiber optic communication system converts electrical signals into optical signals and then sends them through optical fibers. When the light waves are demodulated into electrical signals at the receiving end, the information is transmitted.More precisely, electrical signals are modulated into light waves at the transmitting end. Modulation can be accomplished in a variety of ways, including phase modulation, frequency modulation, and intensity modulation. Through optical fibers, the modulated light pulses are sent to the receiving end. The light waves are demodulated into electrical signals at the receiving end, and the optical signals are converted into electrical signals through a demodulator to restore the original information.2. Constituent elementsThe constituent elements of fiber optic communication include light sources, photodetectors, optical fibers, and optical amplifiers. Light sources are used to generate light waves, light detectors are used to detect light waves, optical fibers are used to transmit light waves, and optical amplifiers are used to amplify the energy of light waves.1. Light source: It is one of the main parts of the optical fiber communication system, generating and transmitting optical signals through optical fibers. Light-emitting diodes and lasers can generate high-intensity and high-stability optical signals and are examples of commonly used light sources.2. Light detector: It is used to detect optical signals at the receiving end and convert them into electrical signals for subsequent processing and recovery of the original information.3. Optical fiber: It is the transmission medium of the optical fiber communication system. It is a long and thin tube made of glass or plastic, which is usually filled with a substance with a high refractive index so that the optical signal can be transmitted in it.4. Optical amplifier: It is used to amplify the energy of the optical signal in order to maintain the strength and stability of the signal during long-distance transmission.3. Advantages1. Transmission bandwidth: The transmission bandwidth of optical fiber communication can achieve high-speed and large-capacity data transmission.2. Strong anti-interference: Optical fiber communication is not affected by electromagnetic interference, so it has strong anti-interference.3. Low signal attenuation: The signal attenuation of optical fiber communication is much smaller than that of traditional cables, so long-distance transmission can be achieved.4. Good confidentiality: Since optical fiber communication uses light wave transmission, it has high confidentiality.4.
