摘要

这项研究提出了一种混合环网拓扑基础双向 4 × 40/40 Gbps 集成无源光网络/自由空间光学（PON/FSO）系统。该系统采用二维修正固定右移（2D-MFRS）编码，具有更强的抗灾能力和故障保护能力，特别是在主光纤可能遭到破坏的偏远地区。研究结果表明，支持 250 个用户的拟议系统可提供忠实的 100 千米光纤和 1 千米 FSO 混合传输。此外，在弱到强湍流和雨雾天气条件下，固定 50 千米光纤距离的最大 FSO 传输距离可达 21 千米。此外，它还能提供 -39 dB m 的接收器灵敏度，与其他设计相比，所提出的设计非常出色。

Disaster resilience hybrid ring-mesh topology basics integrated PON/FSO system incorporating 2D-MFRS code

This work proposes a hybrid ring-mesh topology basics bidirectional 4 × 40/40  Gbps integrated passive optical network/free space optics (PON/FSO) system. The system incorporates two-dimensional modified fixed right shifting (2D-MFRS) code with enhanced disaster resilience and fault protection capability especially in remote places where the primary fibre may be destroyed. The obtained results depict that proposed system supporting 250 subscribers can provides faithful hybrid 100 km fiber and 1 km FSO transmission. Also, maximum FSO range of 21 km with fixed 50 km fiber distance can be obtained concerning weak-to-strong turbulent and rain with fog weather conditions. In addition, it also offers −39 dB m receiver sensitivity and the proposed design is superb over other work.
