具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1、图2和图5，本发明实施例提供一种可拆卸式光口的光模块，包括模块主体1以及光口塑胶件2，所述模块主体1的光口处开设有供所述光口塑胶件2插入的凹槽10，所述光口塑胶件2与所述凹槽10之间为可拆卸连接。在本实施例中，可拆卸的光口塑胶件2可以独立的拆卸和更换，而不需要拆开模块的主体，这样可以使这种光模块方案更加方便通过替换光口的塑 胶件将其改制成为AOC模块，而且不需要再重新做性能测试，有效提高了产品方案的灵活性，有助于产品降成本。具体地，在模块主体1靠近光口处设凹槽10，光口塑胶件2可以从该凹槽10插入，由于光口塑胶件2与凹槽10之间是可拆卸连接，在需要时可以从凹槽10中取出，进而不需要拆开模块主体1就可以过替换光口的塑胶件将其改制成为AOC模块。
作为本发明实施例的优化方案，请参阅图1、图2、图3、图5、图6和图7，所述模块主体1包括底座组件11以及盖设于所述底座组件11上的上盖12，所述上盖12上具有供光口螺钉13安装以锁定所述光口塑胶件2的光口螺纹孔130。所述模块主体1还包括PCB板14，所述PCB板14设于底座组件11上并由所述上盖12盖压在所述底座组件11上。所述模块主体1还包括内部跳线15，所述内部跳线15连在所述PCB板14上。所述模块主体1还包括散热片16，所述散热片16设于所述上盖12和所述底座组件11之间。在本实施例中，内部跳线15、上盖12、散热片16、PCB板14、COB组件以及底座组件11组成所述模块主体1，其中，上盖12上开设有光口螺纹孔，当光口塑胶件2装入凹槽10后，可以从此处安装光口螺钉13以将光口塑胶件2锁定，当需要拆卸时，拧开该光口螺钉13即可，当然可拆卸连接的方式不限于该螺钉固定的方式，还可以有例如卡接、磁接等方式，本实施例对此不作限制。PCB板14、内部跳线15均属于本领域常规部件，此处就不再详述。在上盖12和底座组件11内设散热片16可以提升光模块的散热能力。
作为本发明实施例的优化方案，请参阅图1至图4，所述底座组件11包括底座17以及可拉动以使光模块解锁的拉手18，所述凹槽10设于所述底座17和所述上盖12靠近光口处。所述拉手18包括设于所述底座17的光口处的手柄180以及可于所述底座17的侧面上滑动的解锁滑片181。所述底座组件11还包括用于解锁后复位的弹簧19。所述拉手18上具有供所述弹簧19安装的弹簧安装位182。在本实施例中，凹槽10一部分在上盖12，一部分在底座 17，二者组合起来才是凹槽10。通过拉手18可以实现光模块的解锁，具体地该拉手18包括两个部分，一是手柄二是解锁滑片181，在底座17的侧壁设有可使解锁滑片181于其上滑动的导向槽，拉手18向后拉动，解锁滑片远离手柄的一端的手指可以从笼子中脱出，从而完成解锁。而在设置了弹簧19后，在解锁完毕后，通过弹簧19的弹性可以使得解锁滑片回弹至初始状态。在拉手18上设供弹簧19安装的弹簧安装位182，方便弹簧19的安装。
作为本发明实施例的优化方案，请参阅图6和图7，所述上盖12具有安装导电胶的点胶槽120。在本实施例中，上盖12具有螺纹孔121，可以供螺钉旋入以使上盖12和底座17连接，该螺纹孔的位置可以设在不同的位置，只要能够将上盖12和底座17连起来即可。可以在点胶槽120中设柔性的导电胶，通过螺钉紧固压力确保上盖12和底座17之间的配合缝隙封堵。
请参阅图1至图8，本发明实施例还提供一种AOC光模块的侧视方法，所述AOC光模块3为上述的可拆卸光口的光模块，具体包括如下测试步骤：
S1，将所述光口塑胶件2从所述凹槽中取出；
S2，在所述模块主体不拆开的情况下，取下AOC光模块的尾纤，然后在可拆卸光口位置安装SR光模块的光口塑胶件，此时即可将AOC光模块改制成为SR光模块；
S3，给所述SR光模块接上自环光纤进行带电老化测试；
S4，待测试完毕且测试合格后，将自环光纤取下，装上尾纤30以及所述光口塑胶件2，完成测试。
在本实施例中，采用了上述光模块的可拆卸光口的技术方案，在对AOC光模块3进行测试时，只需要将光口塑胶件2从凹槽中取出，即可在不拆开模块主体的情况下将尾纤30取出，以更换为SR光模块，接着再给SR光模块配置自环光纤进行带电老化测试就很容易了，测试完毕后，若是合格的，将自环光纤取下并装上尾纤30以及光口塑胶件2，即可完成测试。现有的AOC 光模块3的尾纤30的长度都很长，一般是5～20m，甚至可以根据需要做得更长，整个产品的体积比普通的光模块产品要大得多，所以再记性带电老化测试时，对设备的体积要求就成倍数增加，通常一个测试箱是可以一次性测试很多个小的光模块的，但由于AOC光模块3体积大，一个箱子可能都放不下，盘绕起来光纤后或许也只能测试一个或两个，这对于老化工艺来说是一个严峻的挑战，而且带电老化过程中如果老化箱内部不够清洁，很容易使光缆脏污影响产品外观从而造成不良。因此本实施例通过上述的可拆卸光口的形式，可以在不拆开上盖的情况下很容易地将较长的尾纤30取下更换为SR光模块从而进行带电老化测试，其中自环光纤的尺寸就小得多，可以提高测试的效率。光模块行业标准是，光模块完成性能测试后，不拆开模块主体情况下，换装部分零部件，是不需要重新对光模块进行测试的。如此可以有效解决老化设备资源不足的问题以及老化过程中容易导致光缆脏污的问题。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
