具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合附图,对本公开的具体技术方案做进一步详细描述。本公开实施例提供的光模块可以是任意类型的可插拔类的光模块,例如:SFP(Small Form-factor Pluggable),SFP+(10G Small Form-factor Pluggable),XFP(10G Small Form Factor Pluggable)和QSFP+(40G Quad Small Form-factor Pluggable Plus)等可插拔光模块,也可以是其它的用于网络中光电转换的光模块,对此本公开实施例不做限制。
相关技术中,为了获取光模块的工作状态,存在以下两种实现方式:
1、在光模块使用的网络设备面板上设置显示光模块工作状态的指示灯。图1为相关技术中设置有指示灯的设备面板示意图,如图1所示,该面板上的指示灯显示了设备中各光模块(如图1所示的XFP、GPON(Gigabit-Capable Passive Optical Networks)、SFP、SFP+)的工作状态。然而,这种实现方式需要事先获知指示灯与光模块的对应关系,甚至需要仪表及专业测试人员确定光模块的工作状态,因此获取光模块工作状态的效率较低。
2、在光模块壳体的上表面(如图2所示)或下表面开孔,并在光模块中设置导光柱,将光模块内部电路板上的指示灯发出的光通过导光柱导出到光模块上表面或下表面的开孔处。然而,这种实现方式只能将光导出到光模块上表面或下表面,在现有集成度较高的设备中,光模块上表面或下表面可能被其它设备遮挡,从而导致用户无法通过目视观察到光模块的工作状态。
基于此,在本公开的各种实施例中,将指示部分显露在光模块的光接 口的端口上,不需要事先获知指示灯与光模块的对应关系,且由于光接口端面不存在被使用光模块的设备遮挡的情况,因此安装在光接口端面上的指示部件也不存在被相关设备遮挡的情况,从而使工作人员可以直观、轻松地确定光模块的工作状态,提高了获取光模块的工作状态效率。
图3A示出了本公开实施例光模块的结构爆炸图,图3B示出了本公开实施例光模块的结构整体装配图,本公开实施例的光模块10,包括:指示部件100、底座组件200、第一电路板组件300以及上盖组件400;其中,
所述底座组件200,设置在所述第一电路板组件300的底部;
所述上盖组件400,设置在所述第一电路板组件300的上部,与所述底座组件200连接以将所述第一电路板组件300包覆在内;在所述底座组件200与所述上盖组件400连接所形成的腔体结构的一个侧面设置有光接口;
所述指示部件100,配置为指示所述第一电路板组件300的工作状态,显露于所述腔体结构有光接口的侧面的外表面。
这里,第一电路板组件300(可以称为光电转换电路板组件)用于将所述光模块接收到的光信号转换为电信号或者将电信号转换为光信号。模块的主要转化功能均集中在所述第一电路板组件300上,因此所述第一电路板组件300的工作状态即反应了所述光模块10的工作状态。在实际应用时,所述第一电路板组件300设置有工作状态输出接口,通过所述工作状态输出接口能够输出表征所述第一电路板组件300工作状态的指示信号,使得与所述输出接口连接的指示灯以不同的发光状态指示所述第一电路板组件300的工作状态。
这里,实际应用时,所述底座组件200和所述上盖组件400的材质可以为锌合金或铝合金等。
具体实施时,指示部件100可以包含导光器件(如导光柱等)和指示灯(如发光二极管(LED,Light Emitting Diode)等)。实际应用时,所述 导光器件设置在光接口端面上,所述指示灯可以设置在所述第一电路板组件300上,或所述底座组件200与所述上盖组件400连接所形成的腔体结构中的其它位置,所述指示灯可以以焊接或连线等方式与所述第一电路板组件300连接,所述导光器件的入光端面与指示灯对齐,从而将所述指示灯的灯光导出到导光器件的发光端面外,如此,导光器件和指示灯一起可以指示所述第一电路板组件300的工作状态。
指示部件100还可以是指示灯(如LED等)。实际应用时,所述指示灯设置在光接口端面上,所述指示灯通过连接线与所述第一电路板组件300连接,如此,所述指示灯可以指示所述第一电路板组件300的工作状态。
这里,所述指示部件100显露于所述光接口端面,如图3B所示,在所述光模块的左端是光接口。本公开实施例采用巧妙的设计将用来指示光模块的工作状态的指示部件100暴露在了光模块的光接口端面的外表面,与相关技术中将指示灯设置在光模块使用的网络设备面板上或光模块壳体的上下表面相比,用户不需要事先获知指示灯与光模块的对应关系,也不存在指示部件被遮挡的情况,如此,用户可以直观、轻松地确定光模块的工作状态,提高了获取光模块的工作状态效率。
当所述指示部件包含导光器件和指示灯时,所述光模块的具体结构如下:

所述第二电路板组件500包括连接部件501及指示灯电路板部件502;其中,所述连接部件501一端与所述指示灯电路板部件502连接,另一端与所述第一电路板组件300连接;所述电路板部件502设置在所述底座组件200上,所述LED 102设置在所述指示灯电路板部件502上。
其中,实际应用时,所述连接部件501包含FPC或导线。图9B中示出的所述连接部件501包含FPC,FPC是以聚酰亚胺或聚酯薄膜为基材制 成的一种具有高度可靠性,绝佳的可挠性印刷电路板,具有配线密度高、重量轻、厚度薄、弯折性好的特点。因此,实际应用时,连接部件501可以在所述上盖组件400和所述底座组件200所形成的腔体结构中弯折,以较好地配合实际的装配情况,并且一般在制板完成时FPC即与电路板部件502连接好,与通过导线与电路板部件502连接的方式相比,减少了电路板后期焊接处理的工序。所述连接部件501通过接插件的方式与所述光电转换电路板部件302上的工作状态输出接口3021连接。
需要说明的是:当所述连接部件501包含FPC时,所述连接部件501一般通过接插件的方式与所述光电转换电路板部件302上的工作状态输出接口3021连接;当所述连接部件501包含导线时,所述连接部件501一般通过焊盘的方式与所述光电转换电路板部件302上的工作状态输出接口3021连接。
如图9B、图9C所示,所述指示灯电路板部件502,设有第一档面503、第二档面504以及第三档面505。所述底座组件200设置有凹槽结构,所述第一档面503、所述第二档面504以及所述第三档面505通过所述凹槽结构设置在所述底座组件200上。具体实施时,如图7A、图7B所示,所述底座组件200设置有凹槽结构,所述底座组件200的第一长槽203和第二长槽204的后方(远离光接口端面201的方向)设有矩形凹槽208,所述矩形凹槽208的左侧(如图7A所示,正视所述光接口时对应的方向)设有第一侧面209,所述矩形凹槽208的右侧设有第二侧面210。所述指示灯电路板部件502的第一档面503、第二档面504以及第三档面505通过所述矩形凹槽208设置在所述底座组件200上。所述指示灯电路板部件502通过粘接方式与所述底座组件200固定。具体实施时,如图9B、图9C所示,所述指示灯电路板部件502还设有A面506(与所述矩形凹槽208靠近的一面)和B面507(与所述A面相背的一面),其中A面506为粘胶面。所述底座 组件200的矩形凹槽208的后方(远离光接口端面201的方向)设有第三粘胶面207,所述指示灯电路板部件502的A面506与所述底座组件的第三粘胶面207粘接固定,由于不需要在所述指示灯电路板部件502的板面上设置辅助部件,因此,粘接固定可以节省所述指示灯电路板部件502的板面面积。
在实际应用时,所述指示灯电路板部件502还可以以螺钉的方式固定在所述底座组件200上。以螺钉固定的方式需要在所述指示灯电路板部件502上开设相应的螺孔。
如图9B所示,所述指示灯电路板部件502的B面507上设置有焊盘5021,以焊接的方式与所述LED 102连接。这里,所述焊盘5021的封装形式与所述LED 102的封装形式适配,并且由于指示灯电路板部件502比光电转换电路板部件302上设置的元器件少,因此将LED 102设置在所述指示灯电路板部件502上比将其设置在光电转换电路板部件302上时,所选用的封装尺寸更大,以便于所述导光柱101和LED 102的对准,提高了装配过程中的容差性。
综上所述,如图7A、图7B所示,所述底座组件200设置有光接口端面201;所述底座组件200设置有槽结构,所述导光柱101通过所述槽结构设置在所述底座组件上200,并保证所述光接口端面201与所述导光柱发光面103平齐;所述底座组件200设置有凹槽结构,所述指示灯电路板部件502通过所述凹槽结构设置在所述底座组件上200,并保证焊接在所述指示灯电路板部件502上的将LED 102与所述导光柱入光面104平齐;所述长槽和矩形凹槽208之间设有腔体202,用于放置所述卡钩611。

此外,一方面,导光柱从光模块内部穿出,没有破坏光模块结构件的完整性,由此所述光模块具有良好的EMI性能;另一方面,通过指示灯电路板组件的转接作用,相较于传统放置在尺寸紧张的光电转换电路板组件上,放置在指示灯电路板组件可以将指示灯的封装尺寸变大,以利于所述导光柱和指示灯的对准,提高了装配过程中的容差性。
