This paper demonstrates the review of performance comparison of optical amplifiers EDFA, SOA and RAMAN amplifiers for secured optical communication systems. The optical amplifiers such as single stage EDFA(SSEDFA), Dual stage EDFA(DSEDFA), tri stage EDFA(TSEDFA), Eight stage EDFA(ESEDFA), single stage SOA(SSSOA), dual SOA stage(DSSOA), tri SOA stage(TSSOA), single stage RAMAN(SSRAMAN), dual stage RAMAN(DSRAMAN), tri stage RAMAN(TSRAMAN) and Eight stage EDFA(ESEDFA) with backward pumping separately simulated with wavelength of 980nm and the input and output parameters of each model measured the input optical power, output optical power, input noise and output noise, Gain, noise figure, Quality factor, BER(Bit Error rate), Eye height and received electrical power values are tabulated, compared and analyzed. The Eight Stage optical amplifiers use only two stage pumping of wavelength 980nm to overcome the wastage of pumping power compared to other optical amplifiers. Single stage optical amplifier uses one pumping wavelength, dual stage uses two pumping wavelengths, Tri stage optical amplifier uses three stage pumping wavelengths and etc., For cascading model, Eight stage EDFA with 128 channels identified as the best and used as repeater gives input multiplexed optical power 9dBm, output optical power 27dBm and receive electrical power 22dBm and quality factor of 3.116 and Eye height 0.005 for long distance world’s telecommunication link
