为了实现更高的频谱效率，少模光纤中的模分复用（MDM）是一个新的研究领域。该想法面临许多技术问题，包括联运延迟和模式耦合，这些问题限制了系统的可实现长度。本文旨在完成阶跃折射率少模光纤中模间延迟的分析。我们对光纤的所有参数进行数值分析，这些参数可能会影响少模光纤中的模间延迟，并确定可以增加多路复用模式数量而不显着增加最大模间延迟的条件。
In order to achieve higher spectral efficiency, mode division multiplexing (MDM) in few-mode fibers is a new research area. The idea faces lots of technical issues including intermodal delay and mode coupling which limit the achievable length of the system. This paper is designated to complete the analysis of intermodal delay in step-index few-mode fibers. We analyze numerically all the parameters of fiber, which could impact intermodal delay in few-mode fibers and identify the conditions which can increase the number of multiplex modes without significant increase in maximum intermodal delay.
