具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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他实施例，都属于本申请保护的范围。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是本申请还可以采用其他不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施例的限制。
正如背景技术部分所述，现有光组件的功耗较大，而光组件的功耗越大，所述光组件的性能受到的影响也越大。
有鉴于此，本申请实施例提供了一种光器件装置，如图1所示，该光器件装置包括：
单板，所述单板上设置有至少一个驱动单元10，所述驱动单元10包括：激光器驱动器11，分别于所述激光器驱动器11的输出端连接的匹配网络12和第一连接件13；
至少一个光组件20，所述光组件20包括电吸收调制激光器21和与所述电吸收调制激光器21连接的第二连接件22，其中，所述第一连接件13和所述第二连接件22可拆卸电连接；
所述激光器驱动器11输出调制信号B，所述调制信号B经由所述第一连接件13和所述第二连接件22输入至所述电吸收调制激光器21，所述电吸收调制激光器21根据所述调制信号B输出激光信号；
眼图判断芯片30，所述眼图判断芯片30用于根据所述电吸收调制激光器21输出的激光信号调节所述匹配网络12的阻抗，直至所述电吸收调制激光器21输出的激光信号的眼图性能满足预设标准。其中，所述预设标准可选为所述光模块领域中标准协 议里，对所述光模块输出激光信号的要求，本申请对此并不做限定，具体视情况而定。
需要说明的是，在上述实施例中，所述激光器驱动器11还输出驱动信号A，所述驱动信号A经由所述第一连接件13和所述第二连接件22输入至所述电吸收调制激光器21，所述电吸收调制激光器21在所述驱动信号A的驱动下工作。
在上述实施例的基础上，在本申请的一个具体实施例中，所述匹配网络12包括可调电阻、可调电感和可调电容中的至少一个。如图2所示，所述电吸收调制激光器21包括激光器211和与所述激光器211连接的电吸收调制器212，所述电吸收调制器212在所述单板输出的调制信号B的控制下，将所述激光器211产生的激光信号进行调制后输出。
由于所述光组件20的尺寸越大，所述光组件20的功耗越大，对所述光组件20的性能影响越大，本申请实施例所提供的光器件装置，将所述激光器驱动器11设置在所述单板上，从而减小所述光组件20的尺寸，降低所述光组件20的功耗，提高所述光组件20的性能。
需要说明的是，传统光器件装置中，所述激光器驱动器、匹配网络和所述电吸收调制激光器都设置在所述光组件上，所述匹配网络和所述光组件是一一对应的，因此，所述光组件只要在出厂前调整好参数后，即可以保证所述光器件装置在后续工作中保持性能不变。而本申请实施例中，所述匹配网络和所述电吸收调制激光器分开设置，即便单板在出厂前调整好所述匹配网络的参数，所述光器件装置在后续使用过程中，也很难保证所述单板上驱动单元的匹配网络和其对应的光组件配对连接，造成所述匹配网络和所述光组件不匹配的现象。而不同的光组件的频率响应存在差异，因此，当与所述光组件连接的单板上驱动单元的匹配网络与该光组件不匹配时，会导致所述光器件装置的眼图性能难以满足预设标准，存在眼图缺陷，影响所述光器件装置的眼图性能。
而本申请实施例所提供的光器件装置还包括眼图判断芯片30，所述眼图判断芯片30用于根据所述电吸收调制激光器21输出的激光信号调节所述匹配网络12的阻抗，直至所述电吸收调制激光器21输出的激光信号的眼图性能满足预设标准。因此，本申请实施例所提供的光器件装置在后续工作时，可以在所述光组件20和所述单板连接之后，所述单板业务通信之前，先利用所述眼图判断芯片30根据所述电吸收调制激光器21输出的激光信号调节所述光组件对应的驱动单元中匹配网络12的阻抗，直至所述电吸收调制激光器21输出的激光信号的眼图性能满足预设标准后，再将所述电吸收调制激光器21输出的激光信号向外输出，以使得所述光器件装置中所述驱动单元的匹配网络12和与所述驱动单元连接的光组件20相匹配。
在上述实施例的基础上，在本申请的另一个实施例中，所述第一连接件13为卡座，所述第二连接件22为插头或金手指，所述单板和所述光组件20通过所述卡座和所述插头(或金手指)实现可拆卸连接。在本申请的另一个实施例中，所述第一连接件13为插头或金手指，所述第二连接件22为卡座，所述单板和所述光组件20通过所述卡座和所述插头(或金手指)实现可拆卸连接。在本申请的其他实施例中，所述单板和 所述光组件20还可以通过其他方式实现可拆卸连接，本申请对此并不做限定，具体视情况而定。
在上述任一实施例的基础上，在本申请的一个实施例中，如图3所示，所述眼图判断芯片30集成在所述单板上，每一所述驱动单元10对应集成一个所述眼图判断芯片30，所述眼图判断芯片30的输入端经由所述第一连接件13与所述第二连接件22连接，所述眼图判断芯片30的输出端与其所对应的驱动单元的匹配网络连接，从而使得所述光组件20中的电吸收调制激光器21输出的激光信号可以依次经由所述第二连接件22和所述第一连接件13输出给所述眼图判断芯片30。
在上述实施例的基础上，在本申请的一个实施例中，继续如图3所示，所述光组件20还包括：
分光片23，所述分光片23用于将所述电吸收调制激光器21输出的光信号按照该分光片23的分光比分成第一光信号和第二光信号；
接收机24，所述接收机24用于将所述第二光信号转换成电流信号；
跨阻放大器25，所述跨阻放大器25用于将所述电流信号转换成电压信号后，依次经由所述第二连接件22和所述第一连接件13输出给所述眼图判断芯片30；
输出端Out，所述第一光信号经由所述输出端Out输出。
在本申请实施例中，所述光器件装置工作时，先利用所述分光片23将所述电吸收调制激光器21输出的激光信号分成第一光信号和第二光信号，再利用所述接收机24和所述跨阻放大器25将所述第二光信号转换成电压信号输出给所述眼图判断芯片30，以便于所述眼图判断芯片30根据所述第二光信号调整所述匹配网络12的阻抗，直至所述第二光信号的眼图性能满足预设标准后，再将所述第一光信号经所述输出端Out输出。
在上述实施例的基础上，在本申请的一个具体实施例中，所述分光比为5:95，即所述第二光信号占所述电吸收调制激光器21输出激光信号的5％，以保证所述光器件工作时，所述电吸收调制激光器21输出的激光信号大部分可以经由所述光组件20的输出端Out输出。
需要说明的是，由于所述第二光信号对所述电吸收调制激光器21输出激光信号的百分比较小，为了保证所述第二光信号可以被所述眼图判断芯片30快速识别，并根据所述第二光信号转换后的电压信号获得所述电吸收调制激光器21输出激光信号的眼图曲线，在本申请的一个实施例中，所述跨阻放大器25再将所述电流信号转换成电压信号后，还具有将所述电压信号放大的作用，但本申请对此并不做限定，具体视情况而定。
具体的，如图4和图5所示，图4为本申请一个实施例所提供的光组件20的结构示意图，图5示出了该光组件20的立体结构示意图，在本申请实施例中，所述光组件20包括：
