Transmitter (II) --- Modulators



The signals transmitted in the optical communication system are carried by light. Therefore, the function of a transmitter is to convert the electronic signals to optical signals in which signals are carried by light. In Chapter 2, we learned how to generate light. Here we will describe how to put signals on the light. A transmitter module therefore includes two parts: a light source and modulator. Its block diagram is shown in Fig. 3-1.
