摘要

我们研究了下一代移动回程网络的性能，该网络基于采用NG-PON2 (TWDM-PON)和FSO技术的混合架构。我们已经建立了下行链路系统的数学模型。然后综合分析了TWDM-PON/ fso混合回程下行链路的性能，同时考虑了光纤和无线链路的各种物理层损伤的影响。比较了不同服务范围的TWDM-PON/FSO系统与相应的NG-PON2s系统的性能。数值计算结果表明，TWDM-PON/FSO组合系统可以充分利用光接入网和FSO技术的优势，为下一代移动回程网络提供灵活的千兆带宽解决方案。

Performance analysis of gigabit-capable mobile backhaul networks exploiting TWDM-PON and FSO technologies

We studied the performance of a next-generation mobile backhaul network that is based on a hybrid architecture employing NG-PON2 (TWDM-PON) and FSO technologies. We have developed a mathematical model of the downlink system. We then comprehensively analyzed the performance of TWDM-PON/FSO-hybrid backhaul downlink while considering the impacts of various physical layer impairments of both optical fiber and wireless links. The performance of TWDM-PON/FSO systems with different service reaches is also compared to that of corresponding NG-PON2s. The numerical results show that the TWDM-PON/FSO-combined system can take the advantages of both optical access networks and FSO technologies to create a promising flexible gigabit-bandwidth-capable solution for next generation mobile backhaul networks.
