OPTICAL DISPERSION COMPENSATION USING DIFFERENT MODULATION FORMATS
Optical dispersion is the main impediment to optimal utilization of optical fiber backbone ability to satisfy the capacity need of today’s emerging telecommunication networks. In this paper, the investigation of post - and symmetrical dispersion compensation fibers (DCF) have been examined in a 16 and 32 channel 40Gbps dense wavelength division multiplexing (DWDM) system using different modulation formats. Simulation results obtained show a significant improvement in the quality factor and bit error rate when DCF is used. The performance of the methods however shows dependency on the number of channels in the system, the modulation, and the channel condition.
