Description

一种光电混合分线盒、光电混合连接系统以及连接方法 技术领域
本发明涉及通信技术领域，尤其涉及一种光电混合分线盒、光电混合连接系统以及连接方法。
背景技术
移动基站包括基带处理单元(Base Band Unit,BBU),电力供应单元(Power Supply Unit,PSU)和需要分别被连接至该两者的射频拉远单元(Radio Remote Unit，RRU)。BBU、PSU和RRU之间的连接包括通过光纤(optical fiber)传输的数据链路和通过电源线传输的电力链路。
当前的一种解决方案是直流电线/光纤相互独立连接(参见图1)。在该方案中，BBU、PSU通过相互独立的电源线和光纤相连接，这种情况下，当一个基站有许多RRU时，会有非常多的光纤和电缆被固定在塔上。
为了简单快速安装和节省费用，通常会采用将光纤和电缆合并在一个波纹管或管套内的、所谓的混合线缆。并且，还需要在大的、用于多个RRU的、结合光纤和电源线的混合主馈线和小的、仅用于一个RRU的独立混合跳线之间建立连接。
当前的混合连接方案主要有两种。第一种混合连接方案如图2所示，一个支持多个RRU的不防水的混合主馈线总成，其两端分别具有多个独立的电源和光纤支路。主馈线总成的分支终端为电源连接端子和光纤连接器。在末端采用所谓的混合跳线支持一个RRU，混合跳线两端的光电分支少于主馈线。在混合跳线上，其分支终端为电源连接头和光纤连接器，一个主馈线通过一个防水的分线盒被连接至多个跳线(通常为四个)。
该解决方案的问题在于，需要在现场打开分线盒进行主馈线和跳线之间的光电连接，电源和光纤连接工作中有可能导致错误的连接。
第二个混合连接方案(参考图3)相比较第一种方案更为先进：其包括一支持多个RRU的防水的光电混合主馈线总成，在主馈线的顶端有且仅有两个独立的电源和光纤的分支。在主馈线总成上，光纤分支的终端含有一个多光纤MPO(Multi-fiber pull off)插芯，电源分支的终端具有多个电源插孔(多插孔电源连接头)。
其中，支持一个RRU的混合跳线的混合连接头为一种户外混合接头(通常为2电源插针4光纤插芯)，位于光电混合分线的下端。
分线盒具有固定于底部的光电分开的两个输入端连接器，光纤输入端包含一个多光纤MPO插芯，电源输入端是一个多插针电源连接头；多个固定于盒上的光电混合输出连接头,分别用于连接主馈线总成和混合跳线。
第一种方案相比，该方案的优点在于消除了大部分现场的电源、光纤的内部连接工作。但是该方案仍然需要额外设计一个具有防水特性的强健扇出结构，以用于对位于主馈线顶部的光纤和电源线进行分线。两种分支同样需要较多的现场安装以及分支装配工作。并且在某些区域，尤其是热带区域，塔顶上跳线的光纤经常会被鸟啄坏，从而导致整个光纤链路(数据链路)的损坏。因此需要有更加快速、简单的安装方案，该方案需要能够保护光纤，能节省费用，并能在RRU和BBU之间提供一种稳定强健的连接。
可知，现有方案中主要存在的问题包括：主馈线顶部具有电源和光纤分支，增加了分线盒内部的现场连接作业的和分支装配固定工作，并且容易造成误连接。需要特定的强健的防水扇出结构，从而增加了费用和现场安装固定工作。

参见图7a至图7e，所述光电混合分线盒2具有一个固定在分线盒底部的光电混合输入端连接器201和多个固定在所述光电混合分线盒面板203上的 光电混合输出端连接器202，所述光电混合输出端连接器(202)位于其所处面板(203)平面与分线盒底面板平面之间。
优选地，分线盒2可以具有多个所述面板203。
例如，参见图7c至图7e，图7c中各个光电混合输出端连接器202位于倾斜表面203上，该倾斜的面板203与水平面具有一定的角度；在图7d中各个光电混合输出端连接器202所处的面板203朝向地面，并与地面平行；在图7e中，分线盒2的各个光电混合输出连接器202位于两个倾斜表面203上，该两个倾斜表面203各自与水平面具有一定的角度，并且，该两个倾斜表面各自与水平面的角度可以不同。
其中，基于主馈线中所包含的光纤的芯数和电源线数量，以及RRU所需的电源线和光纤数量，来确定该分配盒中光电混合输出端连接器202的数量。
例如，图7a和图7d所示的分配盒均能支持4个光电混合输出端连接器，而图7c所示的分配盒可支持5个输出端连接器。
本领域技术人员应可根据实际情况和需要来确定各个分配盒所支持的光电混合输出端连接器202的数量，此处不再赘述。
优选地，所述光电混合输出端连接器202所处面板203向下与地平面形成特定角度，以使得该面板203上所固定的光电混合输出端连接器(202)位于其所处面板(203)平面与分线盒底面板平面之间。
例如，参见图7b，图7b中面板203与竖直面成35°角，与水平面成55°角。
本方案的优点在于，能够使得光电混合分线盒2具有更好的防水性能，有效防止光电混合输出端连接器202被雨水等淋湿进水的风险。
扇出组件3包括所述扇出组件包括波纹管302，与所述波纹管302相连接的多个扇出结构301，以及光电混合跳线连接器303；其中，该扇出结构301包括一个输入端子3012和两个输出端子3011，每个端子的端子口都具有密封橡胶，以使得波纹管302在推入该端子口后构成密封防水的扇出组件3。
优选地，该扇出结构301为U型。
在该光电混合连接系统中，光电混合主馈线连接器101与所述光电混合 分线盒2的光电混合输入端连接器201相匹配；扇出组件3的光电混合跳线连接器303与光电混合分线盒2的光电混合输出端连接器201相匹配。
具体地，与BBU相连接的光电混合主馈线1经由光电混合主馈线连接器101与光电混合输入端连接器201的配合，连接至所述光电混合分线盒2；光电混合分线盒2分出的各路光电混合分支分别经由所述光电混合输出端连接器202与所述光电混合跳线连接器303的配合，连接至所述扇出组件3，以到达RRU。
优选地，扇出组件3所采用的扇出结构301的数量可基于所述光电混合主馈线1中所包含的光纤和电源线的数量，以及RRU端所需的分支数量来确定。
例如，参图6，对于光电混合分线盒2分出来的光电混合分支，该分支包括4芯光纤和2条电源线，可通过采用三个该扇出结构301，将其分为一路电源线、一路接地线和两路光纤共四条线路。
或者，可进一步采用5个扇出结构301，将其分为两路电源线和四路光纤共六条线路。
通过采用任意数量的该种扇出结构，能够简单、方便地对各个缆线进行扇出以获得所需的线路数量，因此具有非常广阔的应用场景。并且，由于不需要像现有技术那样定制专门的扇出结构，因此能够节省大量的开支。此外，该扇形结构通过将波纹管推入扇形结构的端子口中，与端子口中的密封橡皮形成防水结构，从而具有更好的防水性能。
优选地，参考图8a和图8b，根据本方案的光电混合连接系统，其中，所述分线盒光电混合输入端连接器201可包括9个公电源插针2011和母12芯或24芯光纤插芯2012；所述光电混合主馈线连接器101可包括9个母电源插孔1011和公12芯或24芯光纤插芯1012。
更优选地，所述光电混合输入端连接器201和光电混合主馈线连接器101可分别包括防呆键和防呆键槽，以避免在安装时产生误操作。
在使用时，将所述光电混合主馈线连接器与所述光电混合输入端连接器进行配合，以使得所述光电混合主馈线连接至所述光电混合分线盒；并且， 将所述光电混合分线盒的所述光电混合输出端连接器分别与扇出组件的光电混合跳线连接器的配合，以将盒内光电混合支线连接至所述扇出组件；并且，将所述波纹管推入所述扇形结构的端子口中以实现波纹管与所述扇形结构的连接，并采用一组或多组该种连接，对该光电混合支线所包含的线路进行分线，以获得连接至RRU所需的各路分支。
根据本发明的光电混合连接系统，分线盒的输入、输出均采用光电混合线路，从而减少了进行扇出所需的现场连接和固定的作业，并且本方案中只需采用匹配的具有防呆功能的接头，即可方便的进行对接，减少了需要操作的线路数量，从而也降低了误操作的概率，并且，根据本方案中的分线盒的面板设计以及扇出组件的组合方式，因而具有更好的防水性能，且线缆通过波纹管被保护，避免了被鸟啄的情况，从而增强了整个光纤链路的强健性。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化涵括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。此外，显然“包括”一词不排除其他单元或步骤，单数不排除复数。系统权利要求中陈述的多个单元或装置也可以由一个单元或装置通过软件或者硬件来实现。第一，第二等词语用来表示名称，而并不表示任何特定的顺序。
