本文首先列举了目前光纤通信中使用的各种纤维光路器件,并对几种主要器件作了概括性介绍。然后重点叙述用这些器件可能构成的光纤传输系统和网络。同时也谈到了光开关网络以及器件在测量仪器中的应用。文中对器件和系统的发展趋势略有说明。 This article first lists all kinds of fiber optical devices used in optical fiber communication, and gives a general introduction of several major devices. The focus is then on fiber optic transmission systems and networks that may be constructed using these devices. Also talked about the optical switch network and the application of the device in measuring instruments. The article on the development of devices and systems a slight description.
