摘　　要：为了在非线性约束条件下达到最大传输距离所需的最佳发射功率,软件定义光纤接入网是发展的必然趋势。就线速为STM-16和STM-64在不同波数(4λ、8λ和16λ)条件下的商用波分复用无源光网络(WDM-PON),分别对最大传输距离和最佳传输功率进行了建模分析。该网络模型由标准单模光纤SSMF-28、采用1∶64的无源光分路器的远端(RN)、光线路终端(OLT)和光网络单元(ONU)组成。为了提高网络利用率和接收端接收效率,分析了不同波长数和传输距离对高速WDM-PON系统的性能影响;以节约功耗为目的,在发射功率方面,优化了每一个多波段PON的功率配置。In order to obtain the optimum transmitting power required to reach the maximum transmission distance under nonlinear constraints,makes it possible for software to customize optical access network.For the commercial wavelength division multiplexing passive optical network(WDM-PON)with STM-16 and STM-64 of external modulators are modeled and analyzed under different wavenumbers(4λ,8λand 16λ),The power of optimum transmitting and maximum transmission distance are analyzed,respectively.Network model were composed of standard single-mode fiber SSMF-28,1∶64 passive fiber branching at its far end(RN),optical line terminal(OLT)and optical network unit(ONU).In order to improve the network utilization and receiving efficiency,the influence of different wavenumbers and transmission distances on the performance of high data rate WDM-PON system is analyzed.In order to save power consumption,the configuration of each multi-band PON is optimized in terms of transmission power.
