Principle and application of optical fiber communication
9/20/15 | Technical Article | FiberOnSale.comPrinciple of optical fiber communication is first necessary to transfer in the sender information (such as voice) into electrical signals, and then modulated onto the laser beam emitted from the laser, so that the intensity of light with the electric signal amplitude (frequency) changes, and sent through an optical fiber; at the receiving end, the detector receives the optical signal converts it into an electric signal, after demodulation to restore the original information.
