Development of optical fiber communication system is mainly due to the progressive influence of optical source. Laser diode as optical source in optical transmission system is of great attention because laser diode produces coherent monochromatic-light. Furthermore, laser diode has a high quantum efficiency, can be modulated at a very high speed, has small size and compact. The application of such optical source is also wide, ranging from optical signal communication to radar optics. Therefore, laser ...

ABSTRACT
In particular we concentrate on mayor current implementations of optical fiber communications system which employ some form of intensity modulation (1M) of optical source, together with simple direct detection (DD) of the modulated optical signal at receiver- Good receiver where x is 0,3 (factor x ranges between 0 and 1.0 depending on the photo diode material }and SNR excess of 70 dB, is for 25 km transmission distance.
The deployment optical amplifiers, particularly on long IM/DD ...
