具体实施方式

实施例1：
参见图1至图5所示，本实施例提供一种光背板互连系统，其包括子架1、电背板2、光背板3、光线卡4和光交换卡5。
子架1上固定有至少一个电背板2。子架1主要用来为整个光背板互连系统提供支撑架构。
光背板3固定在子架1上，并固定在电背板2的一侧，光背板3 内设有光纤。光背板3为整个光背板互连系统提供光纤路由。
光线卡4固定在子架1上，并位于电背板2远离光背板3的一侧，光线卡4通过电背板2与光背板3对接。
光交换卡5固定在子架1上，并位于电背板2远离光背板3的一侧，光交换卡5通过电背板2与光背板3对接，且光交换卡5、光线卡4和光背板3通过电背板2形成光通路。
光线卡4将输入业务拆分为多路信号，分别传送给个光交换卡5，或者将每个光交换卡5交换来的多路信号合成一个业务对外输出。光交换卡5根据输入线卡送来的信号目的端口，将信号交换到对应的光线卡4上。
本实施例中，由于光交换卡5、光线卡4和光背板3通过电背板2形成光通路。在光背板互连技术的支持下，由于光互连具有带宽高和损耗小的优点，信号的完整性基本不受影响，而且有极好的电磁兼容性能。其简化了传统的电背板信号传输通道，解决了大容量、高速率电背板的高成本、高损耗、易串扰等问题。
实施例2：
参见图1至图5所示，本实施例提供一种光背板互连系统，其包括子架1、电背板2、光背板3、光线卡4和光交换卡5。
子架1上固定有至少一个电背板2。
光背板3固定在子架1上，并固定在电背板2的一侧，光背板3内设有光纤。
光线卡4固定在子架1上，并位于电背板2远离光背板3的一侧，光线卡4通过电背板2与光背板3对接。
光交换卡5固定在子架1上，并位于电背板2远离光背板3的一侧，光交换卡5通过电背板2与光背板3对接，且光交换卡5、光线 卡4和光背板3通过电背板2形成光通路。
进一步地，电背板2上设有光适配器21，光适配器21可在电背板2上浮动，光背板3上设有与光适配器21相连的光纤插头31，光纤插头31与光纤相连，光线卡4和光交换卡5上均设有与光适配器21相连的光连接器6，且光线卡4和光交换卡5上的光连接器6可分别对应在光线卡4和光交换卡5上浮动。
光背板3为一种矩形结构，由多层复合柔性基板压合而成。每层基板内布置若干束柔性光纤，可完成多块光线卡4和光交换卡5之间的光路由交叉管理。每束光纤前端固定有光纤插头31，用于与电背板2上的光适配器21进行对接。
进一步地，电背板2包括电背板印制板22，光适配器21通过螺钉固定在电背板印制板22上，电背板2上还设有电背板导向机构23，电背板导向机构23固定在电背板印制板22上，且电背板导向机构23朝电背板印制板22的一侧凸出。电背板导向机构23通过螺钉固定在电背板印制板22上，在光线卡4和光交换卡5的插拔过程中辅助导向。
本实施例中的光适配器21可在电背板2上浮动，是指以电背板2所在平面为XY平面建立空间直角坐标系XYZ，光适配器21在X、Y、Z方向上有一定的浮动区域。
同理，光线卡4和光交换卡5上的光连接器6可分别对应在光线卡4和光交换卡5上浮动。即是分别以光线卡4和光交换卡5所在平面为XY平面建立空间直角坐标系XYZ，光连接器6在X、Y、Z方向上有一定的浮动区域。
本实施例中，子架1为一种矩形箱体结构，光线卡4和光交换卡5从子架1正面插入子架1中。为了方便插拔，在光连接器6上还设 有导向结构，通过导向结构使得光线卡4和光交换卡5在子架1中实现灵活插拔，从而实现光线卡4和光交换卡5上的光连接器6与电背板2上的光适配器21之间的插接和脱离。并且由于光连接器6和光适配器21可以在光线卡、光交换卡和电背板上浮动，同时光连接器6自带导向结构，使得这种插接是可以通过盲插实现的。
