作为一个光纤通信系统,光纤只是其中最基础的部分,要全面的了解一个光纤通信系统,仅仅认识光纤是不够的。在如图1所示的光纤通信系统中,除了必备的光纤以外,在传输线路中还需要各种辅助器件以实现光纤与光纤之间或光纤与光传输设备之间的连接、耦合等多种功能。这些辅助器件种类繁多,参数复杂,功能及形式各异,常常令人眼花缭乱。接下来我们就对这些常用的器件进行简单的介绍。
As a fiber optic communication system, optical fiber is only one of the most basic part, to fully understand a fiber optic communication system, just know the optical fiber is not enough. In the optical fiber communication system as shown in FIG. 1, in addition to the necessary optical fibers, various auxiliary components are also required in the transmission line so as to realize the connection and coupling among the optical fibers and the optical fibers or the optical fibers and the optical transmission devices Features. These assistive devices are numerous, complex parameters, different functions and forms, often dazzling. Next, we will briefly introduce these commonly used devices.
