集中直流远供系统在分布式基站的应用探讨

Exploration of applying centralized remote feed DC power system in distributed base station

随着"无缝网络"建设和光纤拉远技术的发展,分布式基站已成为了网络建设的主要形式。传统的电源保障模式已无法满足远端有源通信设备的供电需求。本文以中国移动企标的电压范围(225V～380V可调)为标准,通过对集中直流远供系统在工程实践中的应用总结,就系统在分布式基站的应用方面进行探讨。

With the development and application for seamless network constraction and optical fiber pull far technology. Distributed devices have been the main form of network construction. Network element equipment extended to the margin of users makes quality assurance of access network has been more and more important. The traditional power gareetee style cannot reach the demand of remote communication equipment. This article based on the voltage range （adjustable range from 225V to 380V） in China Mobile＇s standard rate. Through summarise of the application of this System in practice, to discuss the system application in distributed base station.
