Description

一种采用拉环解锁的光模块 技术领域
本发明涉及光通信技术领域中光电模块的机械结构，特别是涉及一种采用拉环解锁的光模块。
背景技术
随着互联网、云计算和大数据的迅猛发展，IT基础设施数据中心的建设进一步加快，5G网络开始在发达城市试点，25G SFP28光模块也随之应用于5G信号基站的建设中。25G SFP28光模块除了应用于5G网络，而且还广泛应用于25G数据中心，25G SFP28光模块的最佳输入/输出(I/O)性能和光纤容量是10G以太网性能的2.5倍，并且具有更高的端口密度，还可以通过减少ToR交换机和线缆数量来节约运营成本。SFP-25G-SR光模块主要用于25G数据中心和5G前传CPRI/eCPRI网络。SFP-25G-SR光模块采用可热插拔的SFP28封装，工作波长为850nm，是全双工收发一体模块。它的最大速率高达25.78Gbps，双LC光口，通过多模光纤传输距离最高可达70m(OM3)或100m(OM4)。SFP-25G-SR光模块因能够提供经济高效的25G网络解决方案而受到数据中心的青睐。
在端口越来越密集的设备中，模块的上锁及卸载装置所能使用的空间越来越狭小，解锁时的动作需要更加简单便捷。与此同时，要求用于区分模块类型的色标更为醒目，拉环上要体现出更多的模块信息，方便使用者在众多模块中快速识别。
目前SFP+、SFP28系列模块的上锁及卸载机构主要有两种形式：
第一种模块拉环的长度不会超过模块本体，运动轨迹是圆周，即拉环通过转动带动其他解锁零件工作，实现光模块解锁。
第二种模块拉环的长度超过模块本体，运动轨迹是直线，即拉环通过直线运动带动其他解锁零件工作，实现光模块解锁。
第一种解锁方式对拉环转动过程中周围零部件的装配空间要求比较高，在密集型设备中，拉环解锁过程中有可能和其他模块或者面板产生干涉，导 致拉环无法转动到位不能解锁。这种模块的色标一般做在拉环的手柄上，当模块安装在设备中时，不转动拉环到光口位置，无法识别模块色标。第二种解锁方式如中国专利CN201711326704.8中模块的上锁及卸载装置，模块需要解锁时，拉动长拉环，拉环在模块顶面，解锁装置在模块底面，施加斜向下力拉动拉环会产生较大的弯矩，使得解锁机构滑动块摩擦力非常大，容易卡死，无法解锁。
鉴于以上情况，如何克服现有技术所存在的缺陷，解决上述技术问题，是本技术领域待解决的难题。

基于本实施例提供的上述结构，进一步参考图25，为光模块在终止位置(解锁状态)与笼子配合的剖面图，可以看到，光模块从笼子11中解锁时，所述拉环1被抬起，以使所述制动片4的凸点4-4从所述笼子11中退出，拉住所述拉环1即可将光模块从所述笼子11中卸载。
