Abstract

In the present paper, we have analyzed numerically and parametrically the efficient distributed Raman gain amplification technique in modern metro passive optical networks. Moreover, we have developed and integrated the numerical and parametrical transmission and propagation techniques based on mathematical laboratory (MATLAB) programming to solve the coupled optical wave equations to obtain design parameters, operational characteristics, and its implementation in the lightwave modulated envelop propagation equations for optical transmission of multi Gbit/sec signals in wavelength and dense wavelength division multiplexing optical network communication systems. In the same way, we have investigated numerically and parametrically the basic soliton transmission technique to handle the bit rates and products either per link or per channel in all pumping direction configurations to upgrade modern metro optical network efficiency and best performance in order to support ultra high capacity of multi-Gigabit rates for maximum number of users or subscribers.
