Optical communication is a communication method that uses light waves as carrier waves. There are two ways to boost the bandwidth of the optical path.
One way is to raise the single-channel transmission rate of the optical fiber. The other way is to increase the number of wavelengths sent through one optical fiber. This is called wavelength division multiplexing technology.
Definition
According to the characteristics of the light source, it can be divided into laser communication and non-laser communication. According to the transmission medium, it can be divided into atmospheric laser communication and optical fiber communication. According to the transmission band, it can be divided into visible light communication, infrared light communication and ultraviolet light communication.
Optical communication is a communication method that uses light waves as carrier waves. It uses optical signals to transmit information. This communication method has the advantages of wide transmission bandwidth, large communication capacity and strong anti-electromagnetic interference ability. It has become one of the important technologies in the field of modern communications.
Principle
The principle of optical communication is to change information into optical signals. These signals travel through optical fibers. At the receiving end, the optical signals are converted back into electrical signals for decoding.
This technology is used in many fields. These include telecommunications, the Internet, data centers, medical care, and radio and television. With the continuous advancement of technology, the transmission rate and capacity of optical communication are constantly improving.
Development
The development history of optical communication is long and can be traced back to 1880. At that time, American telephone inventor Bell had already studied and successfully sent and received optical telephones.
As technology has developed, people have used different ways to send optical signals. These include the atmosphere, water, liquid fiber ducts, glass fibers, and optical cables. At present, optical fiber dominates the field of optical communication transmission.
The above is all about what is optical communication.
