How is transmitter used in fibre optic communication system?
Transmitter:
This consists of analog to digital interface (driver). There, the input signal is converted within binary form. In that case, the carrier light is modulating along with respect to the binary digits. The outcome of LED/Laser diode will be ‘ON’ while the bit is ‘1’ and ‘OFF’ when the bit is ‘0’. In this way, the analog signal gets transformed within optical signal.
