摘要

在本工作中，我们分析了基于波长和时分复用(WDM-TDM-PON)的无源光网络中二进制编码的影响。通过数值分析，我们发现与传统的不归零开关(NRZOOK)编码相比，使用双码编码的网络更能容忍群速度色散(GVD)。色散会使NRZ接收机的灵敏度降低5.5 dB，从而限制了用户数量和信道长度。根据分析和结果的观察，我们建议使用Dicode编码将用户数量增加一倍，并将网络长度增加20%(相对于NRZ)。

Group Velocity Dispersion tolerant WDM TDM Passive Optical Networks

In the present work, we have analyzed the effects of dicode coding in a passive optical network based on both wavelength and time division multiplexing (WDM-TDM-PON). By numerical analysis, we observed that network using dicode coding is more tolerant to Group Velocity Dispersion (GVD) as compared to traditional Non-return to zero - on-offkeying(NRZOOK) coding. Dispersion degrades the sensitivity of NRZ receiver by 5.5 dB hence limiting the number of users and channel length. With the observations from analysis and results, we suggest the use of Dicode coding to double the number of usersand increase the length of the network by 20percentin respect to NRZ.
