Since the 1980s, fiber-optic communication systems have revolutionized the telecommunications industry, but also in the digital era plays a very important role. Optical fiber communications transmission capacity, confidentiality and good. Optical fiber communication has now become the main wired communication. The information to be transmitted to the sending side to the transmission unit in the information superimposed on, or modulated onto a carrier signal as an information carrier, and then the modulated carrier wave transmitted through the transmission medium to a remote receiver, the receiver demodulator out of the original information.
The demonstration device use MP3 player music, with the IC circuit loaded into light, and then use the optical total reflection effect, making the loading of the music signal light travels along the fiber; re-use IC circuit decodes the received light, restore music.
