Transmitters, Receivers, and Transceivers
Modern fiber optic transmission systems can be extraordinarily complex as the data rates, channel counts, and transmission distances increase. However, as previously discussed, the basic elements of fiber optic transmission include the transmitter (Tx) that allows for data input and outputs an optical signal, the optical fiber that carries the data, and the receiver (Rx) that decodes the optical signal to output the data.
Basics of a Transmitter
The transmitter in Figure 10.1 uses an electrical interface to encode the data using one of the three modulation schemes previously discussed: amplitude modulation, frequency modulation, and digital modulation. The electrical-to-optical conversion ...
