Due to the increased usage of optical communication, it has become the major topic for the research work among the research community. The optical communication has various sub domains under it. A large number of researches have been done in this domain and some of them are still under process. This study also contributes in this list of researches by working on optical amplifiers in optical communication. At initial stage, first of all the traditional work that has been done in respective domain has been analyzed and it is evaluated that it lacks at various factors such as the amplifiers were not utilized and implemented in an effective way and along with this the NRZ modulation scheme was implemented that has its own drawbacks. After finding the loopholes in traditional work, the proposed work develops a novel mechanism by using the RAMAN and EDFA amplifiers. Along with this, the code schemes like PN codes, FCC codes and Walsh codes are also implemented. The proposed communication system is modeled in two different ways with unique configuration i.e. single stage model with PN code, FCC code, Walsh code and three stage model with PN code, FCC code and Walsh code respectively. In proposed models, the DRZ modulation scheme has been used. After analyzing the simulated results, the proposed models have been found to be quite effective and impressive with lower BER and high Q factor
