本文介绍了一种实用的光纤多种业务传输系统的组成和设计思想。该系统可以在一根光纤上同时传输一路视频信号、一路音频信号(兼对讲信号)和两路2.4kb/S数据信号,用两根光纤实现系统的双向多路传输。文中给出了设计指标和一些测试结果。
This article introduces the composition and design idea of a practical optical fiber multi-service transmission system. The system can simultaneously transmit one video signal, one audio signal (with intercom signal) and two 2.4kb / s data signals on one optical fiber at the same time, and implement two-way multiplex transmission of the system with two optical fibers. The article gives the design index and some test results.
