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

  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...
