Performance Analysis and Comparison of QPSK and DP-QPSK Based Optical Fiber Communication Systems

In this paper, the comparison between advanced modulation schemes i.e. Quadrature Phase Shift Keying (QPSK) and Dual Polarization Quadrature Phase Shift Keying (DP-QPSK) is carried out on single mode optical fiber cable. Models are simulated for long distance communication and high data rates. Different scenarios such as effect of dispersion, optical fiber length, data rate and wavelengths are tested to check the performance of models. The simulations and investigation are done using licensed version of OptiSystem 14.0.
