High Capacity DWDM System Using PDCF & PSMF and Simulation of Design for Different Channel Spacing
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 6
Abstract
The multichannel DWDM system is designed for different dispersion compensation techniques to achieve high capacity. The obligation for the network bandwidth is large in present scenario due to the expansion in multimedia traffic. DWDM improvement is a challenging technique in present time to meet this demand. By comparing different modulation formats it is observed that MDRZ (Modified Duo-binary Return to Zero) is best than CSRZ and DRZ. As a result, it is used for high data rate DWDM system. The PDCF (Pumped Dispersion Compensating Fiber) and PSMF (Pumped Single Mode Fiber) are used in dispersion compensating techniques for 64 × 20 Gbps DWDM system. The results of three compensation methods have been compared for 200GHz, 100GHz and 50 GHz channel spacing in term of bit error rate and Quality factor. It is observed that 100 GHz channel spacing is used to achieve maximum coverage distance and symmetrical compensation show best results as compared to Pre- and Post - compensation
