Purpose & Scientific Principle
This exhibit allows you to experience the principle of optical fiber communication by operating the optical fiber transmitting device.
How to Operate
(1) Definition of optical fiber.
(2) Propagation principle of optical communication.
The realization of optical fiber communication is based on the principle of total reflection of light. When light enters the center of the fiber and propagates, the refractive index n1 of the fiber core is higher than the cladding n2, and the loss of the fiber core is lower than the cladding. In this way, the light will undergo total reflection, and its light energy is mainly transmitted in the core. With the help of continuous total reflection, the light can be transmitted from one end to the other.
