Composition of optical fiber communication systems
The rapid development of optical fiber communication technology in recent years and the wide application range are rare in the history of communications, and are also important symbols of the world’s new technology revolution and the major transmission tools for various information in the future information society. A practical optical fiber communication system requires circuits, equipment, and auxiliary facilities configured to perform various functions to form a communication network entity before it can be put into operation, for example, interface circuits, management systems, and power supply facilities.
Optical fiber communication system work process
The optical fiber communication system must determine the specific system structure according to the user’s needs, the types of services to be transmitted, and the transmission system and technology level used. Therefore, the specific structure of the optical fiber communication system takes various forms, but its basic structure is determined. The working process diagram of the optical fiber communication system.

It can be seen from the compositional structure of the optical fiber communication system that the optical fiber communication system mainly consists of three main parts: an optical transmitter (optical transmission equipment), a transmission optical fiber (optical cable), and an optical receiver (light receiving equipment).
Typical Applications of Fiber Optic Communication Systems
The application of optical fiber is extensive. It can be used as a transmission line, broadband integrated services digital network (ISDN) and optical fiber subscriber line in public telecommunication networks. In addition, it can also be used as a communication line in special environments, such as power plants, chemical plants, and oil depots. Electricity, roads, railways, mines and other occasions. The following figure shows a typical application example: A schematic diagram of the topology of a broadband integrated service fiber access system.
