统计调查的自适应调制光正交频分复用（AMOOFDM）的传输性能进行单信道，光放大器的自由，多模光纤（MMF）为基础的链路，使用强度调制和直接检测（IMDD）。使用统计构建的1000个最坏情况下的MMF链路进行数值模拟，具有在220-490 MHz中点公里的范围内变化的3 dB带宽。结果表明，通过采用实际可用的设备，在99.5%的已经安装的MMF链路中可以实现在300-m上的>30 Gb/s的AMOOFDM信号传输，而通过采用将来可能可用的组件，AMOOFDM技术能够在99.5%的已经安装的MMF链路中支持在150-m上的100 Gb/s的信号传输。此外，从统计角度证实，AMOOFDM对不同类型的光纤和激光器、受限的发射条件以及光连接器偏移等实际实施相关因素具有出色的灵活性和强大的鲁棒性。循环前缀和量化是限制AMOOFDM技术最大传输性能的关键因素。
Statistical investigations of the transmission performance of Adaptively Modulated Optical Orthogonal Frequency Division Multiplexing (AMOOFDM) are undertaken in single-channel, optical amplifier-free, Multimode Fiber (MMF)-based links using Intensity Modulation and Direct Detection (IMDD). Numerical simulations are performed using statistically constructed 1000 worst-case MMF links having 3-dB bandwidths varying in a range of 220-490 MHz middot km. It is shown that, by employing practically available devices, >30 Gb/s over 300-m AMOOFDM signal transmission is achievable in 99.5% of already installed MMF links, while by employing components that may be available in the future, the AMOOFDM technique is capable of supporting 100 Gb/s over 150-m signal transmission in 99.5% of already installed MMF links. In addition, it is confirmed, from a statistical point of view, that AMOOFDM has excellent flexibility and great robustness to different types of fibers and lasers, restricted launch conditions and practical implementation-related factors such as optical connector offset. It is also found that cyclic prefix and quantization are the key factors limiting the maximum achievable transmission performance of the AMOOFDM technique.
