Optimum Values of the Bandwidth of the Optical and Electrical Filters for a System of High Mode Coupling Optical Fibers

摘要

All-optical long-haul network in a rabidly development to increase the optical communication systems capacity. As a point in this direction we report the optimum values of the bandwidth of the optical for a system of high mode coupling optical fibers using DPSK modulation format for the input signal with considering the impairments CD, PMD, PDL, and the noise. Furthermore, we did get the optimum electrical filters bandwidth as well.
