新型光纤用户环路传输设备的研究

Researches in New Fiber Optic Subscriber Loop Transmission Equipment

本文首先论述了用户线采用光纤传输系统的必要性。然后介绍了ＧＨＳ－Ⅱ型光纤用户环路传输设备配置、电路技术方案及研究的几个主要内容。测试结果表明：该设备设计合理、技术先进、运行可靠、技术指标符合ＣＣＩＴＴ相关建议和国家有关标准。

In this paper,the essentiality of using fiber optic transmission media for subscriber loop system is first discussed,then, the main contents of the configuration,circuit planning and research of GHS-Ⅰ Fiber Optic Subscriber Loop Transmission System are presented. The testing results show that the equipment was rationally designed with advanced technologies and operated properly. The specifications of the equipment conform to relative CCITT proposals and national standards of China.
