我们报告了Nyquist WDM系统的GN模型的完全封闭形式近似，它将以前可用的公式的适用范围扩展到以前没有涵盖的光纤损耗和跨度损耗的值。特别是，到目前为止，对于零损耗，已经有了一个闭合形式的公式，而对于至少大约7分贝的跨度损耗，则有另一个封闭形式的公式。新公式对任何光纤损耗和任何跨度损耗值都是准确的。人们对这种新配方的兴趣是多种多样的，从空芯光纤到改进标准系统的建模，这些系统沿着安装的跨度(如接头或连接器)呈现集中损耗。
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).
