Comparison of pre-, post- and symmetrical compensation for 96 channel DWDM system using PDCF and PSMF

Abstract In this paper, we investigate pre-, post-, symmetrical dispersion and power compensation in parallel for 96 channels × 10 Gbps non-return to zero DWDM system using pumped dispersion compensating fiber (PDCF) and pumped single mode fiber (PSMF). The results of three compensation methods have been compared in the term of bit error rate, eye closure penalty and Quality factor and it is found that both post-, and symmetrical compensation methods are provide better results for short haul communication but for long haul communication post-compensation method is the best alternative among other. The impact of bit error rate and eye closure penalty is also observed for large transmission distances and cover 420 km using post-compensation method with acceptable bit error rate (2.3 × 10 −10 ) and eye closure (1.73 dB).
