长距离OFDM/WDM混合PON中基于MILP的网络规划方案

摘要

在满足用户带宽需求和系统功率预算的前提下,针对长距离OFDM/WDM混合无源光网络中的传输技术(光收发器、检测技术和调制方式),提出了基于混合整数线性规划(MILP)的成本效率最优化数学模型.通过该模型,建立了网络规划方案,给出了在不同长距离OFDM/WDM混合PON场景下成本效率最优的传输技术.%This paper proposes an optimized cost-effective mathematical model based on Mixed Integer Linear Programming (MILP),which is applied in transmission technologies (optical transmitters/detection technologies/ modulation technologies) in long reach OFDM/WDM PONs and satisfies bandwidth need of users and power budget of system.With this model,the paper establishes a network planning scheme and provides the most cost-effective transmission technology in different long reach hybrid OFDM/WDM PON scenarios.
