Principle of Optical Fiber Receiving End
Fiber cable can be very flexible, but traditional fiber's loss increases greatly if the fiber is bent with a radius smaller than around 30 mm. Bendable fibers, targeted toward easier installation in home environments, have been standardized as ITU-T. The principle of optical fiber communication is: in the sending end, to transfer the information (such as voice) into electrical signals firstly,then send to laser modulation of the laser beam,strengthen the light signal with the amplitude (frequency) change, and send out. Fiber-optic communication is a method of transmitting data from one point to another by sending infrared light pulses through an optical fibre. Optical fiber consists of a cylindrical core that propagates light and a concentric cladding that surrounds it. The field of applied science and engineering concerned with the design and application of optical fibers is k ielectric materials. Why light? Frequencies ~1015 Hz Theoretical bandwidth limit: each oscillation is 1.
