Analysis the Performance of Hybrid Modulation in WDM-PON System

摘要: 利用 O p t i s y s t e m 和 M a t l a b 软件通过对比混合调制和传统调制方案下 WDM - P ON 光传输系统中不同调至格式( N R Z 、 R Z 、 D R Z ) 、不同速率( 速率 2.5G b / s 、 1 0G b / s ) 和不同信道间隔( 信道间隔 2 5GH z 、 5 0GH z ) 条件下的传输效率, 以接收端系统眼图、 B E R 等指标来衡量系统的传输性能, 进而验证所提出的混合调制方案的优越性和可行性 .

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 2.5 Gb/s, 10 Gb/ s) and different channel interval channel spacing 25 GHz and 50 GHz), 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.
