5G室外微基站用光电快速连接光缆及其使用方法 技术领域
本发明涉及光缆结构的技术领域，具体为5G室外微基站用光电快速连接光缆。
背景技术
4G时代所使用的大多是宏基站，一般部署在通信铁塔上，站址租赁费用高、建造成本高、功耗高且占空间。到了5G时代，由于5G毫米在空气中衰减很大，绕射能力差且波穿透力较差。5G高频段信号覆盖能力大幅缩减，网络密度显著提升。如果按照4G时代大范围铺设宏基站的模式，建网成本和运维成本都将大幅提升，从通信资源的利用和绿色环保的角度考虑，需要更好的解决方案。
基站按照覆盖半径可以分为宏基站、微基站、皮基站以及飞基站，其中宏基站的覆盖半径为200米以上,在26/3G/时达到2km以上,发射功率为几十瓦。宏基站覆盖半轻大，一般进行大范围的广域覆盖，微基站覆盖50-200米之间，部署在热点地区进行深度覆盖，解决宏基站的盲点和信号弱点。微基站的产品特点轻便、功耗低，部署简易，使得运营商可在有效控制成本的前提下，获得基站设备的投资收益。
5G基站建设采用宏微协同，宏站进行广域覆盖、微站深度覆盖的原则方式进行规划部署，在热点区域密集部署小功率微基站，即微基站超密组网来满足未来移动数据流量增长1000倍以及用户体验速率提升10-100倍的需求，相比1G/2G/3G/4G以宏基站为主的时代，微基站在5G时代与宏基站并驾齐驱， 部署数量将会有爆炸式的增长。
现有的光缆普遍适用于宏基站的建设，其外径相对较大，且结构复杂，会增加微基站的铺设成本。

其进一步特征在于：光单元的分支缆与AAU连接部分直接输出出两个DLC/UPC双工连接头，其中一个双工连接头用于使用，另一个双工连接头作为备用，电单元根据AAU设备的功能直接端接或在端接中间增加电压保护装置；
