Abstract:
In this paper, compare performance of pre, post, and symmetrical dispersion compensation technique for 16 channels at 20 Gbps non-return to zero WDM system using dispersion compensating fiber (DCF) and single mode fiber (SMF). In this work we used DCF techniques to compensate dispersion in optical fiber communication. The Various factors like chromatic dispersion, polarization mode dispersion, non-linear effects, second and third order dispersion impose limit on the performance (transmission distance, pulse broadening) of Wavelength division Multiplexing (WDM) transmission system. The results of three compensation techniques have been compared in the term of bit error rate, eye and Quality factor and it is found that symmetrical compensation methods are provide better results for long haul communication. Pre and Post compensation scheme are also provide better result but on comparison of these three schemes the symmetrical compensation perform better then other. The impact of bit error rate and eye closure penalty is also observed for large transmission distances and cover 240 km using symmetrical-compensation method with acheived bit error rate (2.36173×10−89) and quality factor (19.9934 dB).
