Abstract
In this paper, we have investigated the comparative performance of the dense wavelength division multiplexing system using EDFA amplifier for different data formats i. e. non return to zero rectangular (NRZ-R), non return to zero raised cosine(NRZ-RC), return to zero rectangular (RZ-R) and return to zero raised cosine (RZ-RC) for 384 channels. In the proposed system, optical data is successfully transmitted to a distance of 120 KM. It has been observed that non linearity which severely distorts the signals is produced more in case of RZ-R, NRZ-R and NRZ-RC whereas RZ-RC compensates the dispersion loss variations and hence the best modulation format for the proposed system. Various results are shown to justify these results.
