Optical fiber communications have become one of the main pillars of modern communication field with the advantages of high capacity, low energy consumption, high sensitivity, strong anti-interference and high security.
In the experiment, the basic principle of total reflection as the breakthrough point, the students can study the total reflection process and conditions of it, then more profound understand the principle of transmission in the fiber by observing the process.
Main points:
a) The concept of total reflection of light
b) The necessary conditions of total reflection light
