Nonlinear long haul optical transmission systems (NLOTSs) are a highlighted research area in the telecommunication sector. The importance of NLOTSs is increased, by reason of system volume, number of channels and transmission span demands. To achieve the current goals in the telecommunication industry, the system faces remedies called refractive index related nonlinearities (RIrNs). These nonlinearities cause performance discreditation of NLOTSs. In this paper, RIrNs are estimated and treated for NLOTS. This is achieved by applying modulation format indicators and amplitude deviation analysis. Channel spacing, input power, system capacity, fiber length, and quantity of channels parameters are used with reference to optical signal-to-noise ratio (OSNR) and bit error rate (BER) to simulate the preferred NLOTS model.

利用新型调制方案解决光纤通信系统中的非线性损伤

非线性长距离光传输系统 (NLOTS) 是电信领域的重点研究领域。由于系统体积、通道数量和传输跨度需求，NLOTS 的重要性增加了。为了实现电信行业的当前目标，该系统面临着称为折射率相关非线性 (RIrN) 的补救措施。这些非线性会导致 NLOTS 的性能失信。在本文中，RIrN 被估计和处理用于 NLOTS。这是通过应用调制格式指示器和幅度偏差分析来实现的。参考光信噪比 (OSNR) 和误码率 (BER) 使用通道间距、输入功率、系统容量、光纤长度和通道数量参数来模拟首选的 NLOTS 模型。
