Intra- and inter-channel noise evolution along nonlinear, lossy and dispersive optical fibers

Summary form only given. Accumulated noise due to linear and nonlinear effects in the transmission fiber is the major cause of performance degradation in current long-haul dense wavelength division multiplexing (DWDM) systems. Intra- and inter-channel noise evolution in nonlinear, lossy and dispersive optical fibers are systematically reviewed and uniformly treated as a nonlinear random process.
