NEW TRENDS OF FORWARD FIBER RAMAN AMPLIFICATION FOR DENSE WAVELENGTH DIVISION MULTIPLEXING (DWDM) PHOTONIC COMMUNICATION NETWORKS

The technology of dense wavelength-division multiplexing (DWDM) has recently resulted in a considerable increase in the transmission capacity of fiber-optic communication systems up to several terabits per second. The further improvement of the transmission capacity of such systems can be achieved through the expansion of the spectral range of WDM transmission toward the short-wavelength region. Therefore this present paper has proposed and investigated the new trends and progress of fiber Raman amplification for dense wavelength division multiplexing photonic communication networks over wide range of the affecting parameters. As well as we have deeply studied the transmission distances and transmission bit rates within Raman amplification technique in forward pumping direction configuration through standard single-mode fiber using Shannon transmission technique to handle transmission bit rate and product per channel in this direction for upgrading network performance and efficiency to provide maximum amount of transmission data rate to the supported maximum number of users.
