On the transmit side is first necessary to transmit information (such as voice) into electrical signals, and modulation to the laser emits a laser beam, so that the light intensity signal amplitude (frequency) change, and sent via optical fiber; In the receiver, the detector receives the light signa

On the sending end first to transmission of information (such as voice) into electrical signals, and then on the issue of modulation to laser laser beams, make the magnitude of the intensity of the light signal (frequency) by the changes and sent via fibre; at the receiving end, after detector recei

First must (like voice) turn in the transmitting end the transmission information the electrical signal, then modulates on the laser beam which sends out to the laser, causes the light the intensity (frequency) to change along with the electrical signal scope changes, and transmits through the optic
