Optical communication, as the name suggests, is a communication method that uses light to transmit information. Optical communication technology is the latest achievement in the development of contemporary communication technology and has become the cornerstone of modern communication.
The Development History of Optical Fiber Communication and Applications of Modern Optical Fiber Communication
Currently the widely used optical communication method utilizes optical fiber to transmit light wave signals, and this communication method is called optical fiber communication. Optical fiber communication, satellite communication, and radio communication are the three major pillars of modern communication networks, and among them optical fiber communication is the main body, this is because optical communication itself has many outstanding development advantages.
Main Characteristics of Modern Optical Fiber Communication
In optical communication, the optical waveguide needed for long-distance transmission of optical signals is a cylindrical dielectric waveguide called optical fiber (abbreviated as fiber). Optical fiber is a type of dielectric waveguide that works at optical frequencies, and it guides light energy to transmit along the direction parallel to the axis.
