Ultra wide band (UWB) of optical fiber Raman amplifiers in advanced optical communication networks

Abstract

In the present paper, we have analyzed numerically the ultra wide band (UWB) optical fiber Raman amplifiers in advanced optical communication networks. Moreover, we have developed the numerical transmission and propagation techniques based on mathematical laboratory programming to solve the coupled optical wave equations to obtain design parameters, operational characteristics, and its implementation in the light wave modulated envelop propagation equations for transmission of multi Gbit/sec signals in dense wavelength division multiplexing optical communication systems. We have investigated numerically and parametrically the soliton transmission technique to handle the bit rates and products either per link or per channel in all pumping direction configurations to upgrade optical network efficiency in order to support ultra high capacity of number of users. Also, we have concentrated on the fiber Raman optical amplifier is quickly emerging as an important part of ultra long-distance, high-capacity, and high-speed optical communication systems.
