The source used for a fiber optic transmitter needs to meet several criteria: it has to be at the correct wavelength, be able to be modulated fast enough to transmit
Optical transmitter coverts electrical input signal into corresponding optical signal. The optical signal is then launched into the fiber. Optical source is the major component in an optical transmitter.
