本文的目的是概要地介绍几种用作数字传输的光纤的可能性。首先我们要研究各种不同的元件,为了考虑到现实的可能性,我们不能选择正在研究中的相当先进的元件。如象单模光纤,集成光元件之类,也许将来他们是可以发展的,但在这里我们也不采用。根据图1标
The purpose of this article is to outline the possibilities of several optical fibers for digital transmission. First of all, we have to study a variety of different components, in order to take into account the possibility of reality, we can not choose the very advanced components under study. Such as single-mode fiber, integrated optical components and the like, maybe they will be able to develop in the future, but here we do not use. According to Figure 1 standard
