How Do Fiber Optic Cables Transmit Data?
Fiber optics uses light pulses to transmit information through a cable in much the same way that electronic pulses transmit data. A fiber optic line consists of fibers made of glass and sometimes plastic, which hold light pulses by internal reflection. Until this technology was developed, all data was transmitted by pulses through metal wires.Data is Transmitted as PulsesData in the form of electronic pulses is sent to an optical transmitter. This transmitter turns those pulses into light pulses and sends them through the fiberglass cable. At the end of the cable, an optical receiver converts the light pulses back into the original electronic data pulses.Why Fiberglass?Fiberglass cables have been found to transmit data at a faster rate than traditional metal cables. In order to transmit the data in the form of light pulses over a distance without losing strength, the glass fibers within the cable must be reflective. To achieve this, a thin plastic coating is applied to each fiber durin
