光纤直放站

光纤直放站专门为解决远离基站且地上布有光纤的区域信号覆盖较弱的问题.

这个系统由近端和远端两部分构成：近端通过直接耦合基站信号,把射频信号转化为光信号放大后,通过光纤传输给远端.

远端再把接收的光信号转化回射频信号,提供到网络覆盖不足的区域.同时,移动信号也可通过放大并经由相反的方向传输到基站.

特点:

采用IP65防护级别的铝合金机箱,高度防尘、防水、防腐蚀.
支持5G/4G/3G/2G系统.
上下行控制和告警信息可通过同一条光缆传输.
采用波分复用模块实现长距离传输.
更加稳定和优化的信号传输质量.
一个近端最多能支持4个远端,能最大程度地利用光线.
RJ45端口能连接笔记本进行本地监控或采用基于IP的网管系统进行监控,实现远程监控多系统分布式天线系统设备的工作状态,以及通过以太网或LAN把操作参数下载到设备.
