What are the basic components of an optical fiber communication system?
Because the optical fiber or cable length by optical fiber drawing process and cable construction conditions, and the fiber drawing length is limited (such as 1Km). So a fiber line may have a plurality of optical fibers connected. Thus, the connection between the optical fiber, optical fiber and optical coupling and coupling of optical fiber connectors, couplers and passive devices is essential.
A repeater consists of an optical detector, a light source, and a decision regeneration circuit. It has two functions: one is to compensate for the attenuation of an optical signal when it is transmitted in an optical fiber, and the other is the administration of a pulse whose waveform is distorted
An optical fiber or fiber optic cable forms the transmission path of light. Its function is to transmit the modulated signal sent by the transmitter through the optical fiber or optical fiber cable, and then transmit it to the receiver's optical detector to complete the task of transmitting information
The light receiver is to achieve optical light / electricity conversion. It consists of a light detector and optical amplifier. Its function is to make optical fiber or optical signal cable to the light detector into electrical signals, then the level of the weak electrical signals amplified by the amplifying circuit to the receiving end enough. The electrical terminal drain.
The optical transmitter is to realize optical electrical / optical conversion. It is composed of a light source, and the modulator driver. Its function is the future light signals from the electric terminal of the light emitted from the light modulation, be modulated, and then the modulated optical signal is coupled to an optical fiber or cable transmission. The electric machine is a conventional electroniccommunication equipment.
