PERFORMANCE ENHANCEMENT OF DUAL POLARIZATION COHERENT OPTICAL SYSTEMS WITH AND WITHOUT INLINE DISPERSION COMPENSATION
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 4
Abstract
We study and compare the performance of 112Gb/s Dual polarization coherent optical system for single channel coherent system with different modulation techniques,DP- QPSK(Dual Polarization Quadrature phase shift keying), DP-16QAM(Dual Polarization 16 qadrature amplitude Modulation) using numerical simulations with inline DCF(dispersion compensation fiber) and without inline DCF( but with DSP module for dispersion compensation)using SSMF(standard single mode fiber) for the effect of fiber nonlinearities. Inline dispersion post compensation system was explored to mitigate the impact of transmission impairments. Results obtained shows that the performance of DP-QPSK coherent systems with inline dispersion post compensation is better than the electronic dispersion compensation using DSP module as with DCF they have more tolerance to fiber nonlinearities than those with electronic dispersion compensation but for DP-16QAM coherent system the performance with electronic dispersion compensation is better than with inline dispersion compensation.
