单模光纤通信系统中的模分配噪声及新分析方法

The Investigation of Mode Partition Noise in SM Fiber Systems with the Improved Method

本文评述了两种著名的模分配噪声分析方法—ξ参数法和k参数法,沟通了它们的联系,改进了模分配噪声的计算方法,修正了Ogawa的速率—距离积公式。得出了简易的计算公式和比较准确的结果。

Based on the investigation of mode partition noise with parameter k and ξ, simple and convenient formulae are presented to calculate the limitation of the product of bit-rate and transmission distance set by mode partition noise and the previous Ogawa's are then corrected.
