支持超低光纤损耗和短光纤跨距的GN模型闭合公式
A GN-model closed-form formula supporting ultra-low fiber loss and short fiber spans
摘要：
我们报告一个完全封闭的形式近似的GN模型的奈奎斯特WDM系统，扩展了以前可用的公式的适用范围，以前没有覆盖的光纤损耗和跨度损耗的值。特别是，到目前为止，一个封闭的形式公式是零损失，另一个跨度损失至少约7分贝。新公式在任何光纤损耗和任何跨距损耗值上都是准确的。人们对这个新公式的兴趣各不相同，从空芯光纤到改进标准系统的建模，这些系统沿安装的跨度（如拼接或连接器）呈现集中损耗。
英文摘要：
We report on a fully closed-form approximation of the GN model for Nyquist WDM systems that extends the range of applicability of previously available formulas to values of fiber loss and span loss that were not previously covered. In particular, so far, a closed-form formula was available for zero loss, and another for span loss of at least about 7 dB. The new formula is accurate over any fiber loss and any span loss value. The interest for this new formula is varied, ranging from hollow-core fibers to improving modeling of standard systems that present lumped loss along installed spans (such as splices or connectors).
