摘要
随着光纤拉远技术的应用,远端射频单元(RRU)的供电问题日益受到运营商的重视,尤其在供电条件差的边远山区和农村地区,需要用新的方法来降低建设和维护成本以及提高网络运营安全。本文介绍的一体化解决方案为今后拉远基站的建设提供了一种新的思路。
With the application of remote optical fiber technique, the operators pay more attention on the power supply of RRU. Especially in the weak power supply system, such as mountain area and rural area, a new approach is needed to reduce construction cost and improve network operation safety. The overall resolution is given to provide a new consideration on the construction of remote base station.
