| Abstract: | By using the optisystem and MATLAB software,through the comparison of WDM-PON optical transmission efficiency of hybrid modulation and traditional modulation scheme under the condition of different format(NRZ,RZ,DRZ),different rates(rate of 2.5Gb/s,10Gb/s)and different channel interval channel spacing 25 GHz and 50GHz),the transmission performance of the system was measured by taking the eye diagram and bit error rate(BER)of the receive end system as indicators,and then the superiority and feasibility of the proposed hybrid modulation scheme were verified. |
