Fiber optic transmitter is one of the key components in the fiber optic networks. In fiber optic communications, information is first converted from its original form such as voice, data or video, into electrical form, and then the signal is sent to the fiber optic transmitter, which will transform the electrical signal into fiber optic signal.
The hearts of the fiber optic transmitters are the light sources. Function of light source is to convert information from electrical form to optical fiber light. In today’s fiber optic systems, light sources are usually light emitting diodes (LED) or laser diodes (LD). Both of them are small size semiconductor devices used for signal transformation. These components require power supply connections and modulation circuitry. All components are usually manufactured in one integrated package.
