Abstract

In this work, a wheel-based architecture for 50-gigabit per second next-generation passive optical network stage 2 (50G-NGPON2) represents a promising solution for beyond fifth generation networks. A two-dimensional modified fixed right shifting (2D-MFRS) code is designed and implemented in the proposed architecture to enhance the system capacity and security. The results show that the transmission of 50 Gbps per channel signals over 50–200 km fiber offers high receiver sensitivities of − 17.6 dBm in downlink and − 17.7 dBm in uplink direction with less power penalty of 0.8 dB at the bit error rate of 10^–9. In comparisons with existing optical code division multiple access codes, the proposed architecture using 2D-MFRS code supports upto maximum 260 end subscribers, but also ensures superior performance against the fiber linear and non-linear effects. The simulation results show that the proposed wheel based architecture with 1:128 split ratio drastically improves the fiber reach upto 310 km in uplink and 280 km in downlink direction, compared to other existing passive optical networks (PONs). It is also revealed that the proposed design offers preferable results in terms of high gain and output signal to noise ratio with low noise figure as compared to existing 50 gigabit per second time division multiplexing PON, 50G-NGPON2 and conventional PON. The comparative literature reveals the superiority of proposed design over other existing topologies.

基于 ITU-T G.9804.x 标准的轮式架构 50G-NGPON2 融合了 2D-MFRS OCDMA 代码，适用于超越 5G 的网络

摘要在这项工作中，每秒 50 千兆比特的下一代无源光网络第二阶段（50G-NGPON2）的基于轮子的架构是超越第五代网络的一种有前途的解决方案。该架构设计并实现了二维修正固定右移（2D-MFRS）编码，以提高系统容量和安全性。结果表明，在误码率为 10-9 时，通过 50-200 千米光纤传输每信道 50 Gbps 的信号，下行链路和上行链路的接收器灵敏度分别为 - 17.6 dBm 和 - 17.7 dBm，功率损耗分别为 0.8 dB。与现有的光码分多址代码相比，使用 2D-MFRS 代码的拟议架构最多可支持 260 个终端用户，而且还能确保在光纤线性和非线性效应方面的卓越性能。仿真结果表明，与其他现有的无源光网络（PON）相比，采用 1:128 分光比的轮式架构大大提高了光纤的覆盖范围，上行链路可达 310 公里，下行链路可达 280 公里。研究还表明，与现有的每秒 50 千兆比特时分复用 PON、50G-NGPON2 和传统 PON 相比，拟议的设计在高增益和低噪音输出信噪比方面具有更佳的效果。文献比较显示，拟议设计优于其他现有拓扑结构。
