在一种可能的实施方式中，该光模块中的供电器件不仅可以用来传输电能，还可以用来传输一些数据信号，可以根据实际需要，向供电器件调制一些数据信号，一方面可以提高该供电器件的使用灵活性，另一方面可以为光纤信道减轻一定的传输负担。

具体实施方式
一些相关方案中，通信设备，如交换机和AP等，针对每根光电复合缆，其面板上都需要至少设置两个端口，一个作为光端口通过光模块与光电复合缆中的光纤连接，另一个作为电端口用来插光电复合缆的电源连接器，每根光电复合缆占据较多的面板尺寸，不利于交换机和AP等通信设备的小型化发展。
其中，光电复合缆，也可以简称复合缆，是一种包覆有光纤和铜线的线缆，光纤用于实现光信号的传输，铜线用于实现电能的传输，电能的传输也可以称为电能传输和电力传输。
本申请实施例提供了一种光模块，该光模块包括用于实现光电转换的光器件和用于实现电力传输的供电器件，所以该光模块也可以称为光电复合模块，或者，简称复合模块。因此，该光模块一方面可以用来进行光信号和电信号的转换，另一方面可以用来实现PoE。
该光模块可以应用在交换机和AP的连接中，交换机和AP的面板上分别插有一个光模块，插在交换机上的光模块和插在AP上的光模块之间通过复合缆连接，实现交换机和AP的连接。
其中，光模块的第一端用来供复合缆插入，光模块的第二端用来插入通信设备(例如，交换机和AP等)中。
那么，通信设备的面板上具有用来插该光模块的端口(端口也可以称为插口，也即是通信设备的光笼子的插口)，端口中具有与该光模块的光器件的电接头(即下文提及的第二光接头)相连的电接口，该端口中还具有与该光模块的供电器件的电接头(即下文提及的第二电接头)相连的电接口。这种通信设备可以称为更新后的通信设备。
同样，复合缆的端部具有与该光模块的光器件的光接头(即下文提及的第一光接头)对接的光纤连接器，复合缆的端部还具有与该光模块的电接头相连的电源连接器。
这样，复合缆和光模块之间既可以进行光信号的传输，又可以进行电力传输，光模块和通信设备之间既可以进行电信号传输，又可以进行电力传输。
可见，该光模块包括实现光电转换功能的器件(即下文提及的光器件)和实现PoE功能的器件(即下文提及的供电器件)，使得与该光模块配合的通信设备的面板上只需要有用来插该光模块的端口即可，该端口中具有与光器件进行电信号传输的接口，也具有与供电器件进行电力传输的接口，进而可以节省通信设备的面板尺寸，有利于通信设备的小型化发展。
当然，由于该光模块的用于供复合缆插入的第一端具有兼容性，那么，该光模块可以与包括电源连接器的复合缆搭配使用，也可以与传统的不包括电源连接器的光缆搭配使用。也即是，该光模块的第一端不仅能供复合缆插入，也能供光缆插入。
同样，由于该光模块的用于插入通信设备的第二端具备兼容性，那么，通信设备的光笼子中也可以只具有与光模块的光器件的电接头(即下文提及的第二光接头)相连的电接口，而不具有与该光模块的供电器件的电接头(即下文提及的第二电接头)相连的电接口，这种通信设备可以称为更新前的通信设备，本实施例中的光模块也可以与这种更新前的通信设备搭配使用。所以，该光模块的第二端既能插入到光笼子中包括电源连接器的通信设备中，又能插入到光笼子中不包括电源连接器的通信设备中。
以下需要指出：
本实施例所述的光模块，可以是光接收光模块，光发送光模块，光收发一体光模块和光转发光模块等中的任意一种；
本实施例所述的光模块，可以是热插拔光模块和非热插拔光模块中的任意一种；
本实施例所述的光模块，可以是标准封装类型中的任一种，例如，可以是小型可插拔(small form pluggable，SFP)光模块、双密度四通道小型可插拔(quad small form factor pluggable-double density，QSFP-DD)光模块、C型可插拔(C form factor pluggable，CFP)光模块、千兆位接口转换器(gigabit interface converter，GBIC)光模块、10G小型可热插拔(10 gigabit small form pluggable，XFP)光模块等等。
例如，该光模块可以是如图1所示的一种光模块，该光模块为SFP光模块。又例如，该光模块也可以是如图2所示的一种光模块，该光模块为SFP光模块。其中，图1所示的SFP光模块和图2所示的SFP光模块的区别在于拉手条的结构形式。又例如，该光模块也可以是如图3所示的一种光模块，该光模块为QSFP-DD光模块。又例如，该光模块也可以是如图4所示的一种光模块，该光模块为CFP2光模块，其中CFP2光模块是尺寸为CFP光模块的二分之一的光模块。
其中，本实施例对该光模块所属的具体类型不做具体限定，本实施例中光模块可以是按照任意标准封装格式封装的光模块。为便于介绍可以以图1所示的封装类型为SFP的光模块进行示例，其它形式的光模块与之类似，便不再一一赘述。下面将详细介绍该光模块的实现光电转换功能的器件和实现PoE供电功能的器件的具体结构。
如图5所示为该光模块的爆炸结构示意图，该光模块包括壳体1、光器件2和供电器件3。
其中，壳体1作为该光模块的保护壳体，用于保护光模块内部的元器件，起到保护和防尘防水的作用。光器件2为用于实现光电转换功能的器件。供电器件3为用于实现PoE供电功能的器件。
为了更好了解该光模块，下面简单介绍壳体1、光器件2和供电器件3的主要结构以及相对位置关系。
(1)对于该光模块的壳体1。
如图6所示，该光模块的轮廓形状，可以为长方体的盒状结构，相应的，壳体1的形状也可以为长方体的盒状结构。作为一种示例，壳体1可以是沿着长度方向两端敞口的长方体的盒状结构，两端的敞口中一个作为第一插口11，另一个作为第二插口12。另一种示例中，壳体1可以包括上盖和底座，上盖和底座固定形成壳体1，例如，上盖可以具有罩状结构，罩在底座上，又例如，上盖具有板状，底座具有无盖的盒状，上盖盖合在底座上，其中，本实施例对上盖和底座的具体结构不做限定，能够实现上盖和底座相固定之后，能够形成两端敞口的盒状结构即可。
其中，壳体1的第一插口11(位于壳体1的第一端)，用于供复合缆插入，以实现该光模块和复合缆的光纤对接。壳体1的第二插口12(位于壳体1的第二端)，用于插入于通信设备的光笼子中，以实现该光模块和通信设备的电连接。
(2)对于光器件2。
光器件2也可以称为光电子器件，如图7所示，光器件2可以包括第一光接头21、光电转换器件22和第二光接头23，光电转换器件22的一端与第一光接头21相连，另一端与第二光接头23相连，其中，第一光接头21或第二光接头23和光电转换器件22的相连可以包括物理上的相连和电学上的相连。
其中，第一光接头21是一种光纤接头，用于与复合缆的光纤连接器对接，以实现光信号传输，第二光接头23是一种电接头，用于与通信设备的光笼子中的电接口实现电连接，以实现电信号传输。
为了区别于供电器件3的两个电接头，光模块第二端的电接头在文中称为第二光接头23，但其实第二光接头23是一种电接头，并非是一种光纤接头。
如图7所示，光电转换器件22包括第一刚性线路板221和转换器件222，其中，转换器件222包括用来实现光电转换功能所需的元器件，例如，可以包括激光器、探测器、放大器、时钟数据恢复、驱动芯片和信号处理器等元器件。第一刚性线路板221的一端与转换器件222相连，第一刚性线路板221的另一端的表面具有金手指，该金手指形成第二光接头23的导电部。转换器件222的远离第一刚性线路板221的一端与第一光接头21相连，以将转换的光信号通过第一光接头21向外传输给复合缆。
光器件2和壳体1的组装关系可以如图8所示，光电转换器件22的第一刚性线路板221和转换器件222均位于壳体1中，且第一刚性线路板221的远离转换器件222的一端位于第二插口12中，使得第一刚性线路板221的远离转换器件222的一端表面上的金手指位于第二插口12中，这样，第二光接头23位于第二插口12中。而与转换器件222相连的第一光接头21位于壳体1的第一插口11中，可以参见图1所示。
其中，光模块可以是双纤双向光模块，相应的，如图7所示，第一光接头21的数量为两个，一个作为发送端，另一个作为接收端，其中图7中光器件2与线路板之间的连接结构未示出。光模块也可以是单纤双向光模块，相应的，第一光接头21的数量为一个，既作为发送端又作为接收端。其中，本实施例对该光模块具体为双纤双向模块还是单纤双向模块不做限定，附图示例中以双纤双向模块进行示例。
(3)对于供电器件3。
供电器件3用于实现以太网供电中的电力传输。见图5所示，供电器件3包括第一电接头31、供电线路32和第二电接头33，供电线路32的一端和第一电接头31相连，另一端和第二电接头33相连。
其中，第一电接头31和第二电接头33均是电接头，第一电接头31与复合缆的电源连接器电连接，第二电接头33与通信设备的光笼子中的电源连接器电连接。
供电器件3和壳体1的组装关系可以是，如图9所示，供电线路32位于壳体1中，且第一电接头31位于第一插口11处，第二电接头33位于第二插口12中。其中，对于第一电接头31位于第一插口11处，例如，见图1所示，第一电接头31可以位于第一插口11中，又例如，第一电接头31也可以位于第一插口11的周围位置处，下文将会详解介绍。
其中，供电器件3安装在壳体1中以后，第一电接头31可以不影响光模块的第一端的第一插口11的结构特征，这样，虽然该光模块中新增了供电器件3，但是壳体1第一端的第一插口11依然能够供光缆插入。第二电接头33也可以不影响光模块的第二端的第二插口12的结构特征，这样，壳体1的第二端的第二插口12依然能插入不包括电源连接器的光笼子中。
这样，该光模块的两端都具备兼容性，从而，即使是不包括电源连接器的光缆，依然能够插入到该光模块的第一插口11中，与第一插口11中的第一光接头21对接，即使光笼子不包括电源连接器，该光模块的第二插口12依然能够插入到光笼子中，与光笼子中的电接头电连接。
由上述可见，该光模块中集成有供电器件3，那么，该光模块插入到通信设备中以后，既能实现光纤对接，又能实现电力传输，那么，光模块所插的通信设备的面板只需要具有与光模块相匹配的端口即可，无需额外设置用于实现电力传输的电源端口，进而可以节省通信设备的面板尺寸，有利于通信设备的小型化发展。
其中，需要指出的是，下文在未特别指明的情况下，所述的复合缆或者光缆，其光纤连接器，均是与光模块的第一光接头21相匹配的光纤连接器，以便于复合缆或者光缆的光纤连接器能够与第一光接头21对接。同样，所述的通信设备的光笼子的电接口，均与光模块的第二光接头23(第二光接头23是一种电接头)相匹配的电接口，以便于第一光接头21能够插入于光笼子的电接口中，实现电信号的传输。
由于本申请是在常规光模块(也可以称为传统光模块)的基础上新增供电器件3，下面将依次介绍供电器件3的第一电接头31、供电线路32和第二电接头33的结构，以及分别在壳体1中的位置。
(一)对于供电器件3的第一电接头31。
为了实现第一插口11的兼容性，第一电接头31和第一光接头21的位置相互独立，以使第一电接头31不会影响到第一光接头21。
那么，第一电接头31的位置分布可以如下。
其中，第一电接头31的第一电接头导电部311露出于壳体1且位于壳体1第一端处的任意位置，第一光接头21和第一电接头31的位置相互独立，以使第一插口11具备兼容性。
(1)如图10和图11所示，第一电接头31的第一电接头导电部311固定于光模块的中柱5。
其中，有关中柱5的特征，在下文介绍第一电接头31的第一电接头导电部311中时会详细介绍。中柱5和第一光接头21均位于第一插口11中，例如，如图10所示，第一光接头21的数量为两个，该光模块为双光接头光模块，那么，中柱5和两个第一光接头21均位于第一插口11中，中柱5位于两个第一光接头21之间，中柱5将第一插口11划分为两个子插口。
第一电接头导电部311固定于中柱5的方案，又可以包括以下几种可能的情况：
如图10所示，第一电接头导电部311的端部位于中柱5的外端面。例如，第一电接头导电部311，第一电接头导电部311的端部齐平于中柱5的外端面。又例如，如图10中(b)所示，中柱5的外端面具有凹槽，第一电接头导电部311位于凹槽中，第一电接头导电部311的外端面低于中柱5的外端面。
又例如，中柱5的长度小于标准长度，如图10中(a)所示，第一电接头导电部311为柱状结构，其端部伸出于中柱5的外端面，且第一电接头导电部311的伸出于中柱5的部分的长度和中柱5的长度之和，小于或等于标准长度，其中，标准长度为光模块按照标准封装类型封装时，中柱5的长度，也是常规的不包括供电器件3的光模块的中柱的长度。
这样，虽然第一电接头导电部311伸出于中柱5的外端面，但第一电接头导电部311也不会阻挡到不包括电源连接器的光缆在第一插口11中的插入，使得光缆的光纤连接器插入时，光纤连接器不会因为先碰触到第一电接头导电部311而出现无法与第一光接头21对接的情况，进而使得第一插口11具备兼容性。
如图11所示，第一电接头导电部311位于中柱5的内壁表面。例如，如图11中(a)和(b)所示，两个第一电接头导电部311均位于中柱5的同一个内壁表面，又例如，如图11中(c)所示，一个第一电接头导电部311位于中柱5的一个内壁表面，另一个第一电接头导电部311位于中柱5的另一个内壁表面。
其中，第一电接头导电部311的外表面可以高于中柱5的内壁表面，第一电接头导电部311的外表面也可以低于中柱5的内壁表面，例如，如图11中(c)所示，中柱5的内壁具有凹槽，第一电接头导电部311位于凹槽中，使得第一电接头导电部311的外表面低于中柱5的内壁表面，第一电接头导电部311的外表面也可以齐平于中柱5的内壁表面，本申请对此不做限定，能够满足不包括电源连接器的光缆能够插入到第一插口11中与第一光接头21对接即可。
(2)如图12至图14及图17所示，第一电接头31的第一电接头导电部311固定于壳体1的第一端的端面。
其中，第一电接头导电部311的外表面可以齐平于壳体1的第一端的外端面，如图12所示，第一电接头导电部311的外表面也可以凸出于壳体1的第一端的外端面，如图13所示，第一电接头导电部311的外表面也可以凹陷于壳体1的第一端的外端面。对于第一电接头导电部311的外表面凹陷于壳体1的第一端的外端面的情况，壳体1的第一端的外端面具有凹槽，第一电接头导电部311位于凹槽中，例如，第一电接头导电部311的端部低于凹槽的槽口。
其中，第一电接头导电部311的形状可以是圆柱状，也可以是矩形柱状等，本申请对此不做限定。
在一种示例中，第一电接头导电部311固定于壳体1的第一端的端面的方案中，又可以包括以下几种可能的情况：
例如，如图12和图13所示，两个第一电接头导电部311可以位于第一插口11的同一个侧壁的外端面，示例性地，两个第一电接头导电部311位于第一插口11的左侧壁的外端面或者右侧壁的外端面，或者，两个第一电接头导电部311位于第一插口11的顶壁外端面或者底壁的外端面。又例如，如图12和图13所示，两个第一电接头导电部311可以位于第一插口11的不同的侧壁的外端面，示例性地，一个第一电接头导电部311位于左侧壁的外端面，另一个第一电接头导电部311位于右侧壁的外端面。
又例如，如图14所示，第一电接头导电部311位于壳体1的第一端的外边缘处，壳体1的第一端的外边缘具有凸台结构，凸台结构和壳体1的第一端的外边缘的连接处具有凹槽，第一电接头导电部311位于该凹槽中。
(3)如图15所示，第一电接头31的第一电接头导电部311位于第一插口11的内壁。
例如，如图15中(a)、(b)和(c)所示，两个第一电接头导电部311均位于第一插口11的同一个内壁，又例如，如图15中(d)所示，一个第一电接头导电部311位于第一插口11的一个内壁，另一个第一电接头导电部311位于第一插口11的另一个内壁，例如，中柱5位于第一插口11中，将第一插口11划分为左右两个子插口，如图15中(d)所示，一个第一电接头导电部311位于一个子插口的内壁，另一个第一电接头导电部311位于另一个子插口的内壁。
其中，第一电接头导电部311的外表面可以高于第一插口11的内壁。第一电接头导电部 311的外表面也可以低于第一插口11的内壁，例如，如图15中(c)所示，中柱5的内壁具有凹槽，第一电接头导电部311位于凹槽中，使得第一电接头导电部311的外表面低于第一插口11的内壁表面。第一电接头导电部311的外表面也可以齐平于第一插口11的内壁，本申请对此不做限定，能够满足不包括电源连接器的光缆能够插入到第一插口11中与第一光接头21对接即可。
(4)如图16和图17所示，第一电接头31的第一电接头导电部311位于壳体1的靠近第一插口11的外壁，其中，外壁可以是顶壁外表面、底壁外表面或者侧壁外表面。
如图16所示，壳体1的靠近第一插口11的外壁可以具有凹槽，第一电接头导电部311可以位于该凹槽中。
示例性地，如图16中(a)、(b)和(c)所示，以及图17所示，两个第一电接头导电部311均位于同一个外壁，又例如，如图16中(d)所示，一个第一电接头导电部311位于一个外壁，另一个第一电接头导电部311位于另一个外壁。
上述第一电接头导电部311的位置设置，可以应用于双光接头的光模块，也可以应用于单光接头的光模块，虽然图例中是以双光接头的光模块进行示例，但并不作为限定，也可以应用于单光接头的光模块。
另外，对于单光接头的光模块，其第一电接头31的位置还可以按照如下方式分布：如图18和图19所示，第一光接头21的数量为一个；第一光接头21位于光模块的中柱5的第一侧，第一电接头31位于中柱5的第二侧，中柱5的第一侧和第二侧的位置相对。
在一种示例中，如图18所示，第一电接头31可以呈柱状结构，位于中柱5的第二侧，第一电接头31包括柱体和第一电接头导电部311，第一电接头导电部311位于柱体的表面。
在另一种示例中，如图19所示，第一电接头导电部311可以在中柱5的第二侧且位于壳体1的第一端的外端面。例如，第一电接头导电部311为凸出于壳体1的第一端的外端面。又例如，第一电接头导电部311凹陷于壳体1的第一端的外端面。其中，第一电接头导电部311的形状可以是矩形柱状，也可以是圆柱状等。其中，两个第一电接头导电部311在排布上，可以上下排布，也可以左右排布。
以上是关于第一电接头导电部311的位置分布以及第一电接头导电部311的具体形状，无论第一电接头导电部311如何分布，以及无论第一电接头导电部311的是何种具体形状，第一电接头导电部311设置于第一插口11中或者第一插口11的周围以后，均能满足第一电接头导电部311与第一光接头21的位置相互独立，第一电接头导电部311不会影响到光缆的光纤连接器与第一光接头21的对接。
这样，对于包括与第一电接头导电部311相匹配的电源连接器的复合缆，插入到第一插口11中后，复合缆的光纤连接器与第一插口11中的第一光接头21对接，以实现光信号的传输，复合缆的电源连接器与第一电接头导电部311电气连接，以实现电力传输。
而对于不包括电源连接器的光缆，由于第一电接头导电部311并不会阻挡光缆的光纤连接器的插入，使得光缆的光纤连接器能够与第一光接头21的对接，实现光信号的传输。
可见，该光模块的第一端处既有第一光接头21，又有第一电接头31，那么就无须在光模块所插的通信设备(如交换机和AP)的面板上设置供复合缆的电源连接器插入的电源接口，从而能够节省通信设备的面板尺寸，有利于通信设备的小型化发展。
而且，该光模块的第一端的第一插口11既能供包括与第一电接头导电部311相匹配的电 源连接器的复合缆插入，又能供不包括电源连接器的光缆插入，使得该光模块的第一插口11具备兼容性，扩大了该光模块的应用场景，提高光模块的使用灵活性，易于现场做线。
上述是第一电接头31的位置分布，下面将介绍几种第一电接头31的结构形式。
一种是，第一电接头31的第一电接头导电部311包括弯折条，例如，包括两个弯折条，具体的可以参见如下。
第一电接头31和第一光接头21的位置相互独立位于第一插口11中，以实现第一插口11具备兼容性，能够供与光模块的封装类型相匹配的任一线缆插入。这样，包括电源连接器的复合缆能够插入到第一插口11中，而且不包括电源连接器的光缆也能够插入第一插口11中。其中，包括电源连接器的复合缆是，其端部包括与第一电接头31相匹配的电源连接器；不包括电源连接器的光缆是，其端部不包括电源连接器，只包括光纤连接器。
如上述所述，光模块包括中柱5，如图20所示，为中柱5的示意图，如图21所示，中柱5位于第一插口11中，一方面用来支撑第一光接头21，另一方面起到导向和限位作用，让复合缆的光纤连接器准确插入到第一插口11中，与第一插口11中的第一光接头21对接，以实现光信号的传输。
其中，中柱5是标准封装类型的光模块均包括的结构，那么对于不包括供电器件3的光模块，其第一插口11中也安装有中柱5。
如图20所示，中柱5包括支撑板51和导向限位板52，导向限位板52的沿着长度方向的端部连接在支撑板51的表面。如图21所示，中柱5位于壳体1中且靠近第一端的位置，支撑板51靠近壳体1的内部，导向限位板52靠近壳体1的外部。这样，支撑板51和壳体1的侧壁围成第一插口11，而导向限位板52将第一插口11划分为两个子插口。对于双光接头的光模块，第一光接头21的数量为两个，一个第一光接头21位于导向限位板52的一侧，另一个第一光接头21位于导向限位板52的另一侧，两个第一光接头21都位于支撑板51上，支撑板51将两个第一光接头21支撑在第一插口11中。
其中，支撑板51是横在壳体1中，也可以称为横梁。
为了实现第一插口11的兼容性，相应的，如图22所示，第一电接头31的第一电接头导电部311可以固定于中柱5，而不对第一插口11造成影响，例如，不影响第一插口11的尺寸和位置，进而使得第一插口11具备兼容性。
例如，第一电接头导电部311的一部分固定于导向限位板52，另一部分固定于支撑板51。第一电接头导电部311的第一端可以位于导向限位板52的表面，也可以伸出于导向限位板52的外端面。第一电接头导电部311的第二端可以位于支撑板51中，也可以伸出于支撑板51。其中，第一电接头导电部311的第一端为用于与复合缆的电源连接器电气连接的端部，第一电接头导电部311的第二端为用于与供电线路32电气连接的端部。
在一种示例中，安装在中柱5中的第一电接头导电部311能够满足通过的电流大于或等于目标电流值，在目标电压下能够满足安全规定范围。
其中，目标电流值可以根据实际情况设定，例如，目标电流值可以是2A，也可以是2A以上的电流值等，本实施例对此不做限定。
其中，目标电压也可以根据实际情况设定，例如，目标电压可以是48V。每个电压下通常对应一个安全规定范围，例如，48V对应的安全规定范围可以为2毫米。
由于第一电接头导电部311所通过的电流大小，与在第一电接头导电部311上加的电压，以及第一电接头导电部311的电阻相关，而第一电接头导电部311的电阻与第一电接头导电部的横截面积相关，那么可以在已知供电电压(如48V)的情况下，通过调整第一电接头导电部311的横截面积，使第一电接头导电部311能够通过大于或等于目标电流值。
如上述所述，第一电接头导电部311包括两个弯折条，分别记为第一弯折条3111和第二弯折条3112，第一弯折条3111和第二弯折条3112之间的间距，在目标电压下，满足安全规定的范围。例如，向第一弯折条3111和第二弯折条3112提供的电压为48V，那么，两者之间的最小间距大于或等于2毫米。
其中，第一弯折条3111和第二弯折条3112中一个用来与电源正极相连，另一个用来与电源负极相连。例如，第一弯折条3111用来接入+48V，第二弯折条3112用来接入-48V。
如图23所示，第一弯折条3111的一部分和第二弯折条3112的一部分可以上下排布，且位于同一竖直平面内，第一弯折条3111的一部分和第二弯折条3112的一部分可以左右排布，且位于同一水平平面内。
例如，如图23所示，第一弯折条3111包括依次相连的第一段3111a、第二段3111b和第三段3111c，第二弯折条3112包括依次相连的第四段3112a、第五段3112b和第六段3112c。如图23所示，第一弯折条3111和第二弯折条3112在中柱5中的排布可以是，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a上下排布，且位于同一竖直平面内，第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c左右排布，且位于同一水平平面内。其中，上下排布也即是如图23所示，沿着z轴方向上下排布，左右排布也即是如图23所示，沿着y轴方向左右排布。
下面将介绍第一弯折条3111的结构特征，以及第二弯折条3112的结构特征。
(1)对于第一弯折条3111，如图23所示，第二段3111b的一端和第一段3111a的侧部相连，第二段3111b的另一端和第三段3111c的侧部相连，且第一段3111a和第三段3111c位于第二段3111b的异侧，第一段3111a和第三段3111c之间具有高度差。
其中，第一段3111a、第二段3111b和第三段3111c一体成型，由金属条(如铜条)通过弯折而形成。
如图23所示，第二段3111b的一端和第一段3111a的侧部相连，两者的连接处为一次弯折，该处的弯折是为了促使第一弯折条3111向下方(如z轴负方向)延伸，以使第一段3111a和第三段3111c之间形成高度差，该次弯折后，第一段3111a和第二段3111b不在同一竖直平面内，该次弯折可以称为改变方向的弯折。
如图23所示，第二段3111b的另一端和第三段3111c的侧部相连，两者的连接处为一次弯折，该处的弯折是为了促使第一弯折条3111向y轴的负方向延伸，使第一段3111a和第三段3111c位于第二段3111b的异侧，例如，第一段3111a位于第二段3111b的第一表面处，第三段3111c位于第二段3111b的第二表面处，该次弯折后，第二段3111b和第三段3111c不在同一竖直平面内，该次弯折可以称为改变方向的弯折。
可见，第一弯折条3111包括至少两次改变方向的弯折。
其中，第一段3111a的形状可以是如图23所示的弯折结构，当然，第一段3111a的形状也可以是水平结构，本申请对此不做限定，能够实现将第一弯折条3111安装在中柱5中即可。
其中，第一段3111a和第二段3111b之间的连接可以为圆角连接，第二段3111b和第三 段3111c之间的连接也可以为圆角连接。
(2)对于第二弯折条3112，如图23所示，第二弯折条3112的弯折和第一弯折条3111的弯折相匹配。
其中，第二弯折条3112的弯折主要是为了与第一弯折条3111的弯折相适配，以拉开两者之间的间距，使两者之间的最小间距满足安全规定的范围(也可以简称安规)。
例如，第五段3112b的一端和第四段3112a的一端相连，第五段3112b的另一端和第六段3112c的端部相连，且第四段3112a和第六段3112c位于第五段3112b的异侧，第四段3112a和第六段3112c之间具有高度差。
其中，第四段3112a、第五段3112b和第六段3112c一体成型，由金属条(如铜条)通过弯折而形成。
其中，第五段3112b的一端即是沿着第五段3112b长度方向的一端，同样，第四段3112a的一端也是沿着第四段3112a长度方向的一端。
如图23所示，第四段3112a和第六段3112c之间具有高度差，第五段3112b的一端和第四段3112a的一端相连，第五段3112b的另一端和第六段3112c的端部相连，那么，第四段3112a和第五段3112b的连接处虽然有弯折，但是第四段3112a和第五段3112b位于同一竖直平面内，所以该次弯折为未改变方向的弯折。同样，第五段3112b和第六段3112c的连接处虽然有弯折，但是第五段3112b和第六段3112c位于同一竖直平面内，所以该次弯折为未改变方向的弯折。可见，第二弯折条3112的第四段3112a、第五段3112b和第六段3112c均位于同一竖直平面内。
在一种示例中，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a用于与复合缆的电源连接器进行电气连接。第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c用于与供电线路32进行电气连接。
其中，第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c，均是第一电接头导电部311的靠近供电线路32的连接部。
第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c的形状均与供电线路32相匹配。
例如，如果供电线路32为柔性线路板，那么，第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c可以均是如图23所示具有片状结构，第三段3111c和第六段3112c均焊接在柔性线路板的表面。
又例如，如果供电线路32为线缆，那么，第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c可以均具有圆环状结构，以便于供电线路32的端部固定位于圆环状结构中。
上述是第一电接头导电部311的第一弯折条3111和第二弯折条3112的结构特征，下面将介绍第一电接头导电部311在中柱5中的安装关系。
第一电接头导电部311在中柱5中的安装关系可以是，如上述所述，中柱5包括支撑板51和导向限位板52，如图22所示，第一电接头导电部311的一部分固定在导向限位板52中，一部分固定在支撑板51中，且第一电接头导电部311从导向限位板52中露出，以便于与复合缆的电源连接器相连，第一电接头导电部311从支撑板51中露出，以便于与供电线路32相连。例如，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a均从导向 限位板52中露出，第一弯折条3111的第三段3111c和第二弯折条3112的第六段3112c均从支撑板51中露出。
其中，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a均从导向限位板52中露出的方式具有多种。
例如，一种方式可以是，如图22所示，导向限位板52包括第一板体521和第二板体522，第一板体521的高度小于第二板体522的高度，第一板体521位于第二板体522的一端，第二板体522的远离第一板体521的端部位于支撑板51的表面；第一弯折条3111的第一段3111a的一部分位于第一板体521的上表面，另一部分位于第二板体522中，第二弯折条3112的第四段3112a的一部分位于第一板体521的下表面，另一部分位于第二板体522中。
其中，第一板体521用于和复合缆的电源连接器的插口相配合，故第一板体521也可以称为第一电接头连接部，其在材质上可以是塑胶件等绝缘材料。第二板体522主要用于固定第一电接头导电部311，故第二板体522也可以称为第一电接头安装部，其在材质上可以是塑胶件等绝缘材料。
在一种示例中，第一板体521和第二板体522之间的连接具有多种方式。例如，第一板体521和第二板体522之间的连接也可以胶粘或者螺钉等方式实现连接，又例如，第一板体521的端部和第二板体522的端部通过胶粘或者螺钉等实现固定连接。又例如，第一板体521和第二板体522一体成型，如图22所示，第一板体521和第二板体522是一块板体的两部分，第一板体521的高度小于第二板体522的高度，这是因为第二板体522的顶部和底部用来与第一插口11的顶部和顶部分别固定连接，其高度和第一插口11的高度相适配，而第一板体521用来与复合缆的电源连接器插接，其高度和复合缆的电源连接器相适配，故第一板体521和第二板体522的高度可以不相等。其中，本实施例对第一板体521和第二板体522的高度不做限定，技术人员可以根据实际情况，灵活选择。
这样，插入于第一插口11中的是复合缆，则第一板体521可以进入到复合缆的电源连接器的插口中，使得第一板体521上表面的第一弯折条3111的第一段3111a，第一板体521下表面的第二弯折条3112的第四段3112a，均与电源连接器的插口中的导电部电气连接。而插入于第一插口11中的如果是不包括电源连接器的光缆，那么由于第一板体521的外端部其实是中柱5的外端部，不会影响光缆向第一插口11中的插入。进而，虽然在中柱5中安装了第一电接头导电部311，但是也不会影响光缆插入到第一插口11中，使得第一插口11具备兼容性。
又例如，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a均从导向限位板52中露出的另一种方式可以是，如图24所示，导向限位板52的远离支撑板51的端部具有凹槽523；第一弯折条3111的第一段3111a位于凹槽523的上槽壁，第二弯折条3112的第四段3112a位于凹槽523的下槽壁。
其中，凹槽523也可以称为中空结构。凹槽523在形状上可以是如图24所示的柱状通孔，或者，也可以是圆柱状通孔，或者，还可以是十字型通孔等，本实施例对凹槽523的具体结构不做限定。
这样，插入于第一插口11中的复合缆的电源连接器的插头可以进入到凹槽523中，使得凹槽523上槽壁的第一弯折条3111和凹槽523下槽壁的第二弯折条3112均与复合缆的电源连接器的插头表面的导电部电气连接。而插入于第一插口11中的光缆，其不包括电源连接器， 由于凹槽523槽口处的端部其实是中柱5的外端部，不会影响光缆向第一插口11中的插入。进而，虽然在中柱5中安装了第一电接头导电部311的第一弯折条3111和第二弯折条3112，但是也不会影响光缆插入到第一插口11中，使得第一插口11具备兼容性。
又例如，如图25所示，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a均从导向限位板52中露出的另一种方式可以是，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a的端部均在导向限位板52的外端面上形成触点。
又例如，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a均从导向限位板52中露出的另一种方式可以是，如图26所示，第一弯折条3111的第一段3111a和第二弯折条3112的第四段3112a的端部均伸出于导向限位板52的外端面。该方案中为了实现第一插口11的兼容性，第一弯折条3111的第一段3111a的伸出于导向限位板52外端面的部分的长度和中柱5的长度之和，小于或等于为中柱5的标准长度，同样，第二弯折条3112的第四段3112a的伸出于导向限位板52外端面的部分的长度和中柱5的长度之和，小于或等于为中柱5的标准长度。其中，中柱5的标准长度是指光模块安装标准封装类型进行封装时，中柱5的长度。
为了将内部固定有第一电接头导电部311的中柱5装配在壳体1中，相应的，如图27所示，中柱5的沿着高度方向的端部具有条形导向块53，如图28所示，第一插口11的内壁具有条形导向槽111；条形导向块53和条形导向槽111相匹配，条形导向块53位于条形导向槽111中。
例如，如图27所示，中柱5的导向限位板52的位置相对的顶部和底部均具有条形导向块53，如图28所示，第一插口11的位置相对的顶壁和底壁均具有条形导向槽111；回过来见图1所示，导向限位板52顶部的条形导向块53位于壳体1顶壁的条形导向槽111中，导向限位板52的底部的条形导向块53位于壳体1的底壁的条形导向槽111中。
其中，如图27所示，条形导向块53可以是条形凸起结构，相应的，如图28所示，条形导向槽111可以是条形凹槽结构，条形导向块53和条形导向槽111相适配，例如，条形导向块53的尺寸和条形导向槽111的尺寸相匹配，条形导向块53的位置和条形导向槽111的位置相对应。
这样，固定有第一电接头导电部311的中柱5，在壳体1中安装中，导向限位板52的条形导向块53在对应的条形导向槽111中滑行，直至条形导向块53在条形导向槽111中被限位，不能继续滑行，当条形导向块53在条形导向槽111中停止滑行时，固定有第一电接头导电部311的中柱5，在壳体1中完成安装。
在一种示例中，为了使条形导向块53在条形导向槽111中的滑行，相应的，如图29中(a)所示，条形导向块53的宽度由第一端a向第二端b逐渐加宽，条形导向块53的第一端a是朝向壳体1外部的端部，条形导向块53的第二端b是朝向壳体1内部的端部。
示例性地，条形导向槽111的槽宽与条形导向块53的宽度相适配，例如，一种情况可以是，如图29中(b)所示，条形导向槽111的槽宽由第一端a向第二端b逐渐加宽，条形导向槽111的第一端a是朝向壳体1外部的端部，条形导向槽111的第二端b是朝向壳体1内部的端部。又例如，另一种情况也可以是，条形导向槽111的槽宽大于条形导向块53的最小宽度，且小于条形导向块53的最大宽度，也即是，条形导向槽111的槽宽大于条形导向块 53的第一端a的宽度，且小于条形导向块53的第二端b的宽度。这样，条形导向块53在条形导向槽111中滑行的过程中，条形导向块53不会从条形导向槽111中滑出，条形导向块53可以被限位在条形导向槽111中。从而使得中柱5能够稳定安装在壳体1中。
上述是第一电接头导电部311包括弯折条的介绍，第一电接头导电部311还可以是弹簧针或者导电柱，具体的参见如下介绍。
如图30所示，第一电接头导电部311可以是弹簧针，也可以称为pogopin，第一电接头导电部311也可以是导电柱，本实施例对第一电接头导电部311的具体结构不做限定，下面可以以第一电接头导电部311为弹簧针，以及第一电接头导电部311为导电柱进行举例说明。
如图30所示，第一电接头导电部311为弹簧针，弹簧针主要包括针轴、针管以及内部的弹簧，针轴能够在弹簧的作用下，在针管中伸缩滑行。
其中，弹簧针固定于中柱5，例如，弹簧针的一部分固定于中柱5的导向限位板52，另一部分固定于支撑板51，且如图30所示弹簧针的针轴伸出于导向限位板52的外端面，以便于与插在第一插口11中的复合缆的电源连接器电气连接，弹簧针的远离针轴的端部伸出于导向限位板52，以便于与供电线路32电气连接。
关于弹簧针的针轴的端部和中柱5的外端面之间的位置关系，与中柱5的长度相关，该光模块按照标准封装类型进行封装时，中柱5的长度为标准长度。在中柱5的标准长度下，光缆的光纤连接器插入于第一插口11中时，中柱5不会阻挡光缆的光纤连接器与第一光接头21的对接，进而使得第一插口11具备兼容性。如果中柱5的长度小于标准长度，则光缆的光纤连接器插入于第一插口11中时，中柱5也不会阻挡光缆的光纤连接器与第一光接头21的对接。但是如果中柱5的长度大于标准长度，则光缆的光纤连接器插入于第一插口11中时，中柱5会阻挡光缆的光纤连接器与第一光接头21的对接，具体阻挡为，光缆的光纤连接器无法与第一插口11中的第一光接头21对接。
基于中柱5的长度和第一插口11的兼容性的原则，弹簧针的针轴的端部和中柱5的外端面之间的位置关系如下：
(1)中柱5的长度为标准长度的情况。
对于弹簧针的针管，由于中柱5的长度为标准长度，而针管不具有伸缩性，所以弹簧针的针管位于中柱5中。例如，弹簧针的针管的端部齐平于中柱5的导向限位板52的外端面，又例如，弹簧针的针管完全位于中柱5的导向限位板52中。
对于弹簧针的针轴，由于针轴具有伸缩性，所以，只需满足当第一插口11中插有复合缆时，弹簧针的针轴的端部齐平于中柱5的导向限位板52的外端面即可。而对于当第一插口11中未插有复合缆的情况，弹簧针的针轴可以凸出于中柱5的导向限位板52的外端面，也可以齐平于中柱5的导向限位板52的外端面。而为了使复合缆的接头插入于第一插口11中时，复合缆的电源连接器的导电部能够与弹簧针的针轴紧密结合，以确保导电良好性，相应的，当第一插口11中未插有复合缆的接头时，弹簧针的针轴可以凸出于中柱5的导向限位板52的外端面，且当第一插口11中插有复合缆时，弹簧针的针轴的端部齐平于中柱5的导向限位板52的外端面。
(2)中柱5的长度小于标准长度的情况。
对于弹簧针的针管，由于中柱5的长度小于标准长度，所以弹簧针的针管完全位于中柱 5的导向限位板52中，也可以是弹簧针的针管的端部齐平于中柱5的导向限位板52的外端面，还可以是弹簧针的针管的端部稍微凸出于中柱5的导向限位板52的外端面。但是对于弹簧针的针管的端部稍微凸出于中柱5的导向限位板52的外端面的情况，针管的凸出部分的长度与中柱5的长度之和，小于或等于标准长度，以避免阻挡光缆的光纤连接器与第一光接头的对接。
对于弹簧针的针轴，当第一插口11中未插有复合缆时，弹簧针的针轴的端部凸出于中柱5的外端面，且针轴的凸出部分的长度和中柱5的长度之和，大于标准长度；当第一插口11中插有复合缆时，弹簧针的针轴的端部凸出于中柱5的外端面，且针轴的凸出部分的长度和中柱5的长度之和，小于或等于标准长度。这样，当复合缆插入第一插口11中时，既能满足针轴不阻挡光缆的光纤连接器与第一光接头的对接，又能实现复合缆的电源连接器与针轴的紧密接触，确保导电良好性。当然，也可以是，当第一插口11中未插有复合缆时，弹簧针的针轴的端部凸出于中柱5的外端面，且针轴的凸出部分的长度和中柱5的长度之和，小于或等于标准长度；当第一插口11中插有复合缆时，弹簧针的针轴的端部凸出于中柱5的外端面，且针轴的凸出部分的长度和中柱5的长度之和，也小于或等于标准长度。
上述是第一电接头导电部311具体为弹簧针的情况，第一电接头导电部311的具体结构也可以为导电柱。
其中，导电柱可以是圆柱结构，也可以是方柱结构，还可以是其它形状的柱状结构，本实施例对此不做限定。
基于中柱5的长度和第一插口11的兼容性的原则，导电柱的端部和中柱5的外端面之间的位置关系如下：
(1)中柱5的长度为标准长度的情况。
如图31所示，导电柱的端部齐平于中柱5的外端面，例如，导电柱的端部齐平于中柱5的导向限位板52的外端面。这样，导向限位板52的外端面上形成导电的触点。这样，复合缆插入到第一插口11中时，复合缆的电源连接器的导电部与导向限位板52外端面上的触点相接触。而不包括电源连接器的光缆插入到第一插口11中，由于中柱5的长度为标准长度，为导电柱的第一电接头导电部311是位于中柱5中，且导电柱的端部齐平于中柱5的外端面，所以，为导电柱的第一电接头导电部311未影响到中柱5的位置和在壳体1中的占据空间，因此，不包括电源连接器的光缆依然能够插入到该光模块的第一插口11中，与第一插口11中的第一光接头21进行对接。
(2)中柱5的长度小于标准长度的情况。
在一种示例中，导电柱的端部凸出于中柱5的外端面，且导电柱的凸出部分的长度和中柱5的长度之和，小于或等于标准长度。这样，复合缆插入到第一插口11中时，复合缆的电源连接器的导电部与导电柱的端部相接触。而如果不包括电源连接器的光缆插入到第一插口11中时，由于导电柱的凸出部分的长度和中柱5的长度之和，小于或等于标准长度，所以，导电部凸出于中柱5的部分不会阻挡光缆的光纤连接器与第一光接头的对接，因此，不包括电源连接器的光缆依然能够插入到该光模块的第一插口11中，与第一插口11中的第一光接头21进行对接。
上述为第一电接头31的第一电接头导电部311的具体结构分别为弹簧针和导电柱的介绍，其中本实施例对第一电接头导电部311的具体结构不做限定，能够实现第一电接头导电 部311固定于光模块的中柱5中后，能够使不包括电源连接器的光缆依然插在第一插口11中，使第一插口11具备兼容性即可。
如上述所述，第一电接头31的第一电接头导电部311的位于壳体1内部的端部与供电线路32电气连接。为了实现第一电接头导电部311与供电线路32的电气连接，相应的，第一电接头导电部311的位于壳体1内部的端部可以伸出于中柱5，以与供电线路32电气连接。例如，如图32所示，第一电接头导电部311为弹簧针，供电线路32为柔性线路板的方案中，弹簧针的远离针轴的引脚伸出于中柱5并穿过柔性线路板的焊盘，弹簧针的远离针轴的引脚焊接在柔性线路板上，以实现弹簧针与柔性线路板的电气连接。又例如，第一电接头导电部311为弹簧针，供电线路32为线缆的方案中，线缆可以缠绕在弹簧针的远离针轴的引脚上，以实现弹簧针与线缆的电气连接。
为了将内部固定有第一电接头导电部311的中柱5装配在壳体1中，相应的，中柱5的沿着高度方向的端部也可以具有条形导向块53，第一插口11的内壁具有条形导向槽111；条形导向块53和条形导向槽111相匹配，条形导向块53位于条形导向槽111中。条形导向块53和条形导向槽111的具体结构可以参见上述所述，此处不再赘述。
(二)对于供电器件3的供电线路32。

在另一种示例中，如图34所示，供电线路32可以为线缆(也即是包覆有铜线的线缆)，线缆的一端与第一电接头31的第一电接头导电部311电气连接，线缆的另一端与第二电接头33的第二电接头导电部331电气连接。
在另一种示例中，供电线路32可以为第二刚性线路板，第二刚性线路板的一端与第一电接头31的第一电接头导电部311电气连接，第二刚性线路板的另一端与第二电接头33的第二电接头导电部331电气连接。
在另一种示例中，在供电线路32为第二刚性线路板的方案中，第二电接头33的第二电接头导电部331可以位于第二刚性线路板的表面。例如，供电线路32可以为第二刚性线路板，第二刚性线路板的一端与第一电接头31的第一电接头导电部311电气连接，第二刚性线路板的另一端伸入至第二插口12中，第二刚性线路板的位于第二插口12中的部分的表面可以具有金手指，这些金手指形成第二电接头33的第二电接头导电部331。
在另一些示例中，如图35所示，供电线路32可以包括第二刚性线路板321和线缆322。第二刚性线路板321的一端与线缆322电气连接，第二刚性线路板321的另一端与第二电接头33的第二电接头导电部331电气连接。或者，第二电接头33的第二电接头导电部331集成在第二刚性线路板321的表面，例如，第二刚性线路板321的一端与线缆322电气连接，第二刚性线路板321的另一端伸入至第二插口12中，第二刚性线路板321的位于第二插口12中的部分的表面可以具有金手指，这些金手指形成第二电接头33的第二电接头导电部331。其中，线缆322的远离第二刚性线路板321的端部与第一电接头31的第一电接头导电部311电气连接。
在另一些示例中，如图36所示，供电线路32包括第二刚性线路板321和柔性线路板323。 第二刚性线路板321的一端与柔性线路板323电气连接，第二刚性线路板321的另一端与第二电接头33的第二电接头导电部331电气连接。或者，第二电接头33的第二电接头导电部331集成在第二刚性线路板321的表面，例如，第二刚性线路板321的一端与柔性线路板323电气连接，第二刚性线路板321的另一端伸入至第二插口12中，第二刚性线路板321的位于第二插口12中的部分的表面可以具有金手指，这些金手指形成第二电接头33的第二电接头导电部331。其中，柔性线路板323的远离第二刚性线路板321的端部与第一电接头31的第一电接头导电部311电气连接。
在另一些示例中，供电线路32也可以包括线缆322和柔性线路板323。例如，第一电接头31的第一电接头导电部311、线缆322、柔性线路板323和第二电接头33的第二电接头导电部331依次电气连接。又例如，第一电接头31的第一电接头导电部311、柔性线路板323、线缆322和第二电接头33的第二电接头导电部331依次电气连接。
在另一些示例中，供电线路32也可以集成在光器件2的第一刚性线路板221，例如，供电线路32也可以是印刷在光器件2的第一刚性线路板221表面的排线。那么，第一电接头31的第一电接头导电部331和第二电接头33的第二电接头导电部331之间可以通过第一刚性线路板221实现电气连接，例如，第一电接头导电部331与第一刚性线路板221的一端相连，第二电接头导电部331与第一刚性线路板221的另一端相连。
供电线路32集成在第一刚性线路板221的方案中，第二电接头导电部331也可以集成在第一刚性线路板221。例如，第二电接头导电部331为位于第一刚性线路板221表面上的金属片。
对于第二电接头导电部331是位于第一刚性线路板221表面上的金属片的方案中，如图51所示，光器件2的第二光接头23为位于第一刚性线路板221表面的金手指，那么，如图51所示，第二电接头导电部331可以为金手指中的未定义金属片，未定义金属片也即是金手指中未被使用的金属片。又示例性地，如图52和图53所示，第二电接头导电部331为在金手指的周围新增的金属片，其中，图52和图53中23-33所指示的为包括第二光接头23和第二电接头33的复合电接头。
对于第二电接头导电部331是位于第一刚性线路板221表面上的金属片的方案中，第二电接头导电部331可以为在金手指的周围新增的金属片，如图52所示，第二电接头导电部331位于金手指的沿着长度方向的端部。或者，如图53所示，第二电接头导电部331位于金手指的沿着长度方向的侧部。其中，本实施例对第二电接头33的第二电接头导电部331相对于第二光接头23的导电部的位置排布不做限定。
在另一种示例中，第一电接头31的第一电接头导电部331、供电线路32和第二电接头33的第二电接头导电部331一体成型。例如，第一电接头导电部331、供电线路32和第二电接头导电部331可以由金属导体加工形成，金属导体的靠近第一端的部分可以形成第一电接头导电部311，金属导体的靠近第二端的部分可以形成第二电接头导电部331，金属导体的其它部分可以形成供电线路32，这样，第一电接头导电部311、供电线路32和第二电接头导电部331三者由金属导体经过加工成型。
其中，本实施例对供电线路32的具体实现方式不做限定，在光模块的实际加工中，可以根据实际情况，灵活选择。
为了不影响光器件2在壳体1中的布局空间，相应的，如图33和图34所示，供电线路 32可以铺设于壳体1的内表面。
例如，例如，如图33所示，供电线路32为柔性线路板，柔性线路板可以铺设于壳体1的内表面。又例如，如图34所示，供电线路32为线缆，线缆可以铺设在壳体1的内表面。又例如，供电线路32包括线缆和柔性线路板，线缆和柔性线路板均可以位于壳体1的内表面。又例如，供电线路32包括线缆和第二刚性线路板，或者，供电线路32包括柔性线路板和第二刚性线路板，那么，线缆或者柔性线路板可以铺设于壳体1的内表面，而第二刚性线路板可以悬空位于壳体1中，以便于第二刚性线路板的表面可以安装一些元器件，例如，可以安装供电线路32用于进行数据信号传输的元器件，可以安装一些元器件，这些元器件可以是光模块接收反馈信息和判断反馈信息的元器件，该部分内容，下文在介绍供电器件32的功能时将会详细介绍。
其中，供电线路32为第二刚性线路板的方案中，第二刚性线路板可以与光器件2的第一刚性线路板221上下并排位于壳体1中。
上述为供电线路32的具体形式，以及供电线路32在壳体1内部的位置，无论供电线路32在壳体1内部以何种方式，以及何种位置排布，供电线路32均不会影响到光器件2在壳体1中的布局空间。
(三)对于供电器件3的第二电接头33。
其中，第二电接头33的一种实现方式中，第二电接头33与第二光接头23的位置相互独立。第二电接头33的另一种实现方式中，第二电接头33和第二光接头23集成在一起，但是两者的导电部相互独立。下面将依次介绍上述两种实现方式。
(1)位于壳体1的第二插口12中的第二光接头23和第二电接头33的位置相互独立，以实现光模块的第二端具备兼容性。其中，光模块的第二端具备兼容性，也可以说，光模块的第二插口12具备兼容性。
如图37所示，光模块包括插拔导向块4，插拔导向块4位于第二插口12中；第二电接头33包括第二电接头导电部331，如图38所示，第二电接头导电部331固定于插拔导向块4；壳体1的第二端能插入于与光模块相匹配的通信设备中，该光模块为标准光模块封装类型中的任一光模块。
其中，插拔导向块4是标准封装类型的光模块均包括的结构，那么对于不包括供电器件3的光模块，其也包括插拔导向块4。光模块插入于通信设备的光笼子中时，如图37所示，光模块的插拔导向块4先与光笼子600相接触，光模块继续向光笼子600中插入中，第二光接头23在插拔导向块4的引导下进入到光笼子600的电接口中，图37中23’指示的为与第二光接头23相对应的电接口。光模块向光笼子中插入的过程中，插拔导向块4还能起到承载一定的作用力，以减少第二光接头23的受力，对第二光接头23所在的第一刚性线路板221形成保护作用，减少光笼子对第一刚性线路板221的作用力。
第二电接头33的导电部，也即是，第二电接头33的第二电接头导电部331，固定于插拔导向块4，使得壳体1的第二端能插入于与光模块的封装类型相匹配的任一通信设备中，该光模块的第二端具备兼容性。
其中，插拔导向块4作为第二电接头33的安装部，是第二电接头导电部331的载体，也可以称为，第二电接头安装部，插拔导向块4在材质上可以是塑胶件等绝缘材料。
如图37所示，插拔导向块4具有板状结构，安装在第二插口12的位于顶部(或底部)的内壁上，例如，可以通过卡接的方式固定在第二插口12的位于顶部的内壁上，又例如，也可以通过胶粘的方式固定在第二插口12的位于顶部的内壁上。
插拔导向块4作为第二电接头导电部331的载体，第二电接头导电部331可以固定在插拔导向块4上，且第二电接头导电部331还与供电线路32电气连接。关于第二电接头导电部331在插拔导向块4的固定位置具有多种。
例如，一种固定位置可以是，如图38所示，第二电接头导电部331为条形金属片；第二电接头导电部331固定于插拔导向块4的与第二光接头23位置相对的外表面，插拔导向块4的外表面为平行于光模块的插拔方向的表面，且第二电接头导电部331的条形方向和光模块的插拔方向平行。
示例性地，如图38所示，第二电接头导电部331可以贴合在插拔导向块4的面对第二光接头23的外表面上。又示例性地，第二电接头导电部331也可以贴合在插拔导向块4的侧壁外表面上。又示例性地，插拔导向块4的侧壁外表面固定在第二插口12的侧壁内表面上时，第二电接头导电部331也可以贴合在插拔导向块4的背对第二光接头23的外表面上。
又例如，如图39所示，第二电接头导电部331为条状的金属弹片，其中，条状的金属弹片也可以称为条形簧片，其结构可以参考图40所示，为条形簧片的第二电接头导电部331包括直线部3311和弯折部3312。
如图39所示，插拔导向块4具有安装槽41，安装槽41在插拔导向块4的外表面具有槽口，插拔导向块4的外表面为平行于光模块的插拔方向的任一表面。其中，平行于光模块的插拔方向的表面可以是插拔导向块4的面对第二光接头23的外表面，也可以是插拔导向块4的侧壁外表面，还可以是插拔导向块4的背对第二光接头23的外表面等。本实施例对此不做限定，可以以面对第二光接头23的外表面进行示例。
如图40并参考图39所示，为条形簧片的第二电接头导电部331的直线部3311位于插拔导向块4中，条形簧片的弯折部3312位于安装槽41中，例如，弯折部3312悬空位于安装槽41中，且弯折部3312的弯折处3312a伸出于安装槽41的槽口，其中，弯折部3312的弯折处3312a为用于和所插设备的接触部电气连接。这样，该光模块插入到设备中时，弯折处3312a可以与所插设备中的导电部相接触实现电气连接。
又例如，如图41所示，第二电接头导电部331为金属杆；第二电接头导电部331固定于插拔导向块4的内部，并伸出于插拔导向块4的远离供电线路32的端面。
示例性地，第二电接头导电部331贯穿插拔导向块4的内部，一端伸出于插拔导向块4的靠近供电线路32的端面并与供电线路32电气连接，另一端伸出于插拔导向块4的远离供电线路32的端面用于与所插设备电气连接。
在一种示例中，为了使得第二电接头导电部331与所插设备的电气连接比较稳定，相应的，如图42所示，金属杆可以是弹簧针，其中弹簧针也可以称为pogopin，弹簧针的针轴能够沿着光模块的插拔方向伸缩。
由于弹簧针伸出于插拔导向块4的端部，用于和通信设备电气连接的端部露出于壳体1，为避免光模块跌落时对弹簧针造成损害，相应的，如图43所示，插拔导向块4包括本体40和保护件；保护件和本体40固定连接，保护件被配置为：当光模块插入于通信设备中时，保护件能使弹簧针的针轴与通信设备的触点紧密接触，当光模块未插入于通信设备中时，保护 件能保护弹簧针的针轴。
保护件的具体实现结构包括多种，例如，保护件的一种结构是参见图43所示，保护件包括滑块42和第一弹性件43，第一弹性件43的弹力小于弹簧针的弹力；本体40的端部具有滑槽401，滑块42和第一弹性件43均位于滑槽401中，且第一弹性件43连接在滑槽401的槽底和滑块42之间；弹簧针的一部分固定位于本体40中，另一部分位于滑块42中，滑块42能相对于本体41和弹簧针滑行，且滑行方向与光模块的插拔方向平行，可以参见图44中的(a)和(b)所示。
其中，第一弹性件43可以是任意具有伸缩弹性的部件，例如，可以是弹簧，这样，滑块42在第一弹性件43的弹性下，能够伸出于滑槽401而不脱离滑槽401，也能收缩于滑槽401中。
这样，当光模块插入于通信设备中时，随着光模块的插入，滑块42在通信设备的推动下，收缩于滑槽401中，由于弹簧针的弹簧大于第一弹性件43的弹性，使得弹簧针的针轴与通信设备的触点紧密接触。而当光模块未插入于通信设备中时，滑块42在第一弹性件43的弹力下，伸出于滑槽401，以将弹簧针包围住，保护弹簧针的针轴。
保护件的另一种结构可以参见图45所示，保护件包括按压件44、第二弹性件45和L型杆46。如图46中的(a)和(b)所示，弹簧针的针轴3313具有凹槽3313a，弹簧针的针管3314的管壁具有通孔3314a，针轴3313的凹槽3313a和针管3314的通孔3314a的位置相对时，针轴3313收容于针管3314中。
如图45所示，按压件44一部分位于本体40外，另一部分位于本体40中，弹簧针、第二弹性件45和L型杆46均位于本体40中，且按压件44、第二弹性件45和L型杆46的第一杆461依次相连，L型杆46的第二杆462的位置和针管3314的通孔3314a的位置相对。
其中，按压件44能够相对于本体40伸缩，伸缩方向垂直于光模块的插拔方向，相应的，如图45所示，按压件44位于本体40的侧部。
这样，当光模块插入于通信设备的光笼子中时，光笼子的插口的内壁对按压件44施加作用力，使按压件44处于按压状态。当光模块拔出通信设备的光笼子中时，光笼子的插口的内壁不再对按压件44施加作用力，按压件44在第二弹性件45的作用下，恢复自然状态，不再处于按压状态。
其中，按压件44的结构可以是便于进入到光笼子中的任意结构，例如，如图45所示，按压件44具有楔形结构，包括斜面，光模块插入通信设备中时，按压件44的斜面先进入到光笼子中。又例如，按压件44也可以具有球面结构，按压件44的伸出于本体40的部分为球面结构。其中，本实施例对按压件44的具体实现结构不做限定。
这样，当光模块插入于通信设备中时，按压件44处于按压状态，L型杆46的第二杆462的端部位于针管3314的外部，以使针轴3313与通信设备的触点紧密接触；而当光模块未插入于通信设备中，且针轴3313收缩于针管3314中时，L型杆46的第二杆462的端部位于针轴3313的凹槽3313a中，以使针轴3313保持收缩于针管3314中。
保护件的另一种结构可以参见图47所示，保护件包括按压件44和U型件47。如图48中的(a)和(b)所示，弹簧针的针管3314具有轴向条形孔3314b，弹簧针的针轴3313具有凸块3313b，凸块3313b位于轴向条形孔3314b中。
如图47所示，按压件44一部分位于本体40外，另一部分位于本体40中，弹簧针和U 型件47均位于本体40中，且U型件47的第一端位于按压件44处，U型件47的第二端位于针轴3313的凸块3321b处。
其中，按压件44能够相对于本体40伸缩，伸缩方向平行于光模块的插拔方向，相应的，如图47所示，按压件44位于本体40的端部。
这样，当光模块插入于通信设备的光笼子中时，光笼子对按压件44施加作用力，使按压件44处于按压状态，而按压件44处于按压状态时，U型件47能够推动弹簧针的针轴3313，促使针轴3313与光笼子中的连接器紧密接触。当光模块拔出通信设备的光笼子中时，光笼子不再对按压件44施加作用力，弹簧针内部的弹簧拉着针轴3313收回，针轴3313的凸块3321b推动U型件47移动，促使按压件44恢复自然状态，不再处于按压状态。
可见，当光模块插入于通信设备中时，按压件44处于按压状态，针轴3313在U型杆47的推动下伸出于针管3314，以与通信设备的触点紧密接触，当光模块未插入于通信设备中时，按压件44处于未按压状态，针轴3313收缩于针管3314中。
上述方案中，第二电接头32和第二光接头23的位置相互独立，且光模块中包括一个刚性线路板，即光器件2的第一刚性线路板221，而光模块中包括两个刚性线路板的方案中，也能实现第二电接头32和第二光接头23的位置相互独立，其中，两个刚性线路板中一个是光器件2的刚性线路板，记为第一刚性线路板221，另一个是供电器件3的刚性线路板，记为第二刚性线路板321。具体方案参见如下。
例如，如图49和图50所示，供电器件3还包括第二刚性线路板321，例如，供电器件3的供电线路32包括第二刚性线路板321，第二刚性线路板321的第一端位于第二插口12中，第二电接头33的第二电接头导电部331为位于第二刚性线路板321表面的金手指。
如图50所示，第二刚性线路板321和光器件2的第一刚性线路板221上下平行位于壳体1中，第二刚性线路板321的第一端伸入至第二插口12中，第二刚性线路板321的位于第二插口12中的部分的表面具有金手指，该金手指可以作为第二电接头33的第二电接头导电部331。
在一种示例中，第二刚性线路板上不仅具有用于实现第一电接头31和第二电接头33实现电气连接的排线，还可以安装一些元器件，以减少光器件2的第一刚性线路板221上的元器件的数量。在另一些示例中，第二刚性线路板321的表面可以安装处理芯片，以加快光模块的处理速度。
而对于第二电接头33与第一电接头31之间的电气连接关系可以是，供电线路32不仅包括第二刚性线路板321，如图49所示，还包括柔性线路板323，第一电接头31、柔性线路板323和第二刚性线路板321依次电气连接。其中，柔性线路板323也可以使用线缆替代。
在一种示例中，第二刚性线路板321与壳体1的内壁距离比较近，那么，该光模块的第二端的第二插口12具备兼容性，能够插入到不包括电源连接器的光笼子中。
上述是通过第二电接头33和第二光接头23的位置相互独立，来实现光模块的第二插口12的兼容性。而通过第二电接头33的导电部和第二光接头23的导电部的位置相互独立，也可以实现光模块的第二插口12的兼容性。具体方案参见如下。
(2)第二电接头33和第二光接头23集成在一起，但是两者的导电部相互独立，也可以实现第二插口12的兼容性。
第二电接头33的第二电接头导电部331为位于第一刚性线路板221表面的金属片。
示例性地，如上述所述，如图51所示，光器件2的第二光接头23为位于第一刚性线路板221表面的金手指，那么，如图51所示，第二电接头导电部331可以为金手指中的未定义金属片，其中，未定义金属片是金手指中的未使用的金属片。又示例性地，如图52和图53所示，第二电接头导电部331为在金手指的周围新增的金属片，其中，图52和图53中23-33所指示的为包括第二光接头23和第二电接头33的复合电接头。
而对于第二电接头33的第二电接头导电部331为在金手指的周围新增的金属片的情况，如图52所示，第二电接头导电部331位于金手指的沿着长度方向的端部。或者，如图53所示，第二电接头导电部331位于金手指的沿着长度方向的侧部。其中，本实施例对第二电接头33的第二电接头导电部331相对于第二光接头23的导电部的位置排布不做限定。
其中，无论第二电接头33的第二电接头导电部331是金手指中的未定义金属片，还是金手指周围新增的金属片，第二电接头33的第二电接头导电部331都是位于第一刚性线路板221的表面上，且位于第二插口12中。
而第一刚性线路板221包括两个位置相对的表面，那么，第二电接头33的第二电接头导电部331位于第一刚性线路板221的第一表面和第二表面中的至少一个表面。
其中，第一表面和第二表面是刚性线路板的一个top面，一个bottom面。
例如，第二电接头导电部331位于第一刚性线路板221的第一表面，又例如，第二电接头导电部331位于第一刚性线路板221的第二表面，又例如，一部分第二电接头导电部331位于第一刚性线路板221的第一表面，另一部分第二电接头导电部331位于第一刚性线路板221的第二表面。
另外，无论第二电接头33的第二电接头导电部331是金手指中的未定义金属片，还是金手指周围新增的金属片，第二电接头33的第二电接头导电部331和第二光接头23的导电部都是集成在第一刚性线路板221的表面，且位于第二插口12中。
那么，该光模块的刚性线路板221的位于第二插口12中的部分可以记为复合电接头23-33，如图54所示，第二光接头23和第二电接头33形成复合电接头23-33；复合电接头23-33包括复合电接头载体23-33-1和复合电接头金手指23-33-2，复合电接头金手指23-33-2固定于复合电接头载体23-33-1的表面上，复合电接头载体23-33-1的表面为平行于光模块的插拔方向的表面；复合电接头金手指23-33-2中第一部分金属片23-33-2a与光电转换器件22电气连接用于形成第二光接头23，复合电接头金手指23-33-2中第二部分金属片23-33-2b与供电线路32电气连接用于形成第二电接头33。
其中，第二部分金属片23-33-2b可以是上述所述的未定义金属片或者新增金属片。
其中，复合电接头载体23-33-1也即是第一刚性线路板221的位于第二插口12中的一部分。复合电接头金手指23-33-2由多个导电触片(也可以称为金属片)组成，铺设在复合电接头载体23-33-1的位置相对的两个表面。
这种将第二光接头23和第二电接头33集成在一起，能够节约光模块的安装空间，有利于光模块的小型化发展。
而且，将第二光接头23和第二电接头33集成在一起，能够实现光模块的第二端的兼容性，使得光模块的第二端不仅能够插入于更新后的通信设备的光笼子中，还能插入于更新后的通信设备的光笼子中。
其中，更新后的通信设备是指，其光笼子中具有与第二电接头33进行电气连接的电源连 接器的设备，更新前的通信设备是指，其光笼子中不具有与第二电接头33进行电气连接的电源连接器的设备。
如上述所述，第一电接头31和第二电接头33之间的电气连接是通过供电线路32和第一刚性线路板221实现，其中，如图55所示，供电线路32可以为柔性线路板，那么，如图56所示，柔性线路板的远离第一电接头31的一端可以焊接在第一刚性线路板221的表面，以实现柔性线路板和第一刚性线路板221的排线电气连接，而第一刚性线路板221的排线的远离柔性线路板的一端与位于第一刚性线路板221的第二电接头导电部331电气连接。
在另一种示例中，供电线路32也可以为线缆，那么，线缆的远离第一电接头31的一端可以与第一刚性线路板221的排线相连，以实现线缆和第一刚性线路板221的排线电气连接，而第一刚性线路板221的排线的远离柔性线路板的一端与位于第一刚性线路板221的第二电接头导电部331电气连接。
其中，无论供电器件3的供电线路32为线缆还是柔性线路板，其都可以铺设在壳体1的内表面。
(四)该光模块的供电器件3在作为电力传输通道时，其应用场景可以如下。
其中，供电器件3主要用于传输电能，作为电力通道，进行电力传输。
因此，该光模块不仅具有用于实现光信号和电信号转换的光器件，还具有用于实现PoE供电的供电器件。这样，光模块插入的设备，如交换机和AP等的面板上可以只设置用来插该光模块的接口，无需再另外设置用来实现PoE供电的接口，进而可以节约设备上的面板尺寸。
如上述所述，该光模块具有实现PoE供电的供电器件3，在应用中，该光模块可以用于在检测到所插入的通信设备为受电设备时，确定通信设备的功耗级别，根据通信设备的功耗级别向通信设备输送电能。
其中，在PoE供电中包括供电设备(Power Sourcing Equipment，PSE)和受电设备(Power Device，PD)，供电设备可以是PoE交换机等，受电设备可以是PoE网络摄像机和AP等。
例如，在一种场景中，交换机的接口中插有该光模块，AP的接口中插有该光模块，交换机上的光模块和AP上的光模块之间通过复合缆连接。交换机是供电设备，AP为受电设备，交换机通过端口向AP输出一个很小的电压，插在交换机上的光模块中的处理器检测到AP为受电设备，支持PoE供电之后，可以向所插的交换机反馈AP为受电设备，然后交换机提高向AP输送的电压，以使插在交换机上的光模块的处理器检测AP的功耗级别，之后，插在交换机上的光模块的处理器根据预先存储的功耗级别和供电电压的对应关系，确定AP的功耗级别所对应的供电电压，并将AP所需的供电电压反馈给所插的交换机，以使交换机按照上述供电电压向AP稳定输送电能。
其中，该光模块中的供电器件3不仅可以用来传输电能，还可以用来传输一些数据信号。
在一些示例中，供电器件3中所传输的数据信号可以包括用于调整光器件的光功率的信号、用于调整光纤信道的信噪比的信号、用于调整光纤信道的S参数的信号，以及光模块出现异常的信号中的至少一种。
既然供电器件3可以传输数据信号，那么，供电器件3可以作为回传通道，回传通道也即是，接收端接收到信号以后，能够向发射端回传一些信息的通道。
供电器件3作为回传通道，那么，对于接收端的光模块，当接收到发射端的光模块发送的光信号时，可以根据光信号，生成第一反馈信息，并将第一反馈信息调制到供电器件3，其中，第一反馈信息用于指示发射端的光模块调整光器件2的参数。例如，第一反馈信息包括用于调整光器件2的光功率的信息、用于调整光纤信道的信噪比的信息，以及用于调整光纤信道的S参数的信息中的至少一种信息，其中S参数也可以称为散射参数，是微波传输中的一个重要参数。
那么，对于发射端的光模块，当通过供电器件3接收到接收端的光模块发送的第二反馈信息时，根据第二反馈信息，调整光器件2的参数。
其中，第二反馈信息也包括用于调整光器件2的光功率的信息、用于调整光纤信道的信噪比的信息，以及用于调整光纤信道的S参数的信息中的至少一种信息。
如果发射端的光模块和接收端的光模块是一对交互的光模块，那么，第一反馈信息和第二反馈信息所携带的内容相等。下面举例说明中，可以以一对交互的光模块进行示例说明。
例如，交换机向AP发送光信号，那么，插在交换机面板上的光模块为发射端，插在AP面板的光模块为接收端。发射端的光模块通过光纤信道向接收端的光模块发送光信号。接收端的光模块接收到发射端的光模块发送的光信号时，会根据光信号，生成反馈信息(即上述的第一反馈信息)，并将反馈信息调制到供电器件3上，供电器件3通过第一电接头31发送至复合缆的铜线中。
反馈信息经由铜线传输至发射端的光模块处，并通过发射端的光模块的第一电接头31传输至发射端的光模块的供电器件3，发射端的光模块供电器件3将反馈信息发送至处理器，处理器解析得到反馈信息(即上述的第二反馈信息)，然后发射端的光模块中的处理器根据接收到的反馈信息，对光器件2的参数进行均衡调整。
作为一种示例，上述反馈信息中包括功率值。那么，发射端的光模块解析得到接收端的光模块接收到的功率值后，与预先存储的接收端的光模块所需的功率阈值进行对比，如果接收到的功率值大于功率阈值。那么，可以降低后续向接收端的光模块发送光信号的功率值，直到接收到的功率值与预先存储的功率阈值比较接近时，停止调整向接收端的光模块发送光信号的功率值。这样，发射端的光模块可以根据接收端的光模块发送的携带有功率值的反馈信息，动态调整所发射的光信号的功率值，达到降低功耗，节约能量的效果。
作为另一种示例，上述反馈信息中包括信噪比或者S参数。那么，发射端的光模块解析得到接收端的光模块发送的光纤信道的信噪比后，如果信噪比比较高，那么，发射端的光模块无需调整参数，而如果信噪比比较低，那么，发射端的光模块可以通过提高发射功率，来提高信噪比，也可以通过调整抽头数的个数和抽头数的系数，来提高信噪比。
这样，供电器件3作为回传通道，使得发射端的光模块能够获取光纤信道中的一些数据，为发射最佳光信号提供依据。而一旦发射的光信号的质量较高，那么对光模块也会形成一定的保护，有利于延长光模块的使用寿命。
又例如，光模块出现故障时，如发送的光信号的功率过小，或者，无法进行光电转换时，可以通过供电器件3向所插设备发送异常信号，以使技术人员可以通过设备了解到光模块出现故障，需要更换光模块。
可见，该光模块具备实现PoE供电的供电器件，该供电器件不仅能够实现电能传输，还能够实现一些数据信号传输。
其中，通过供电器件3传输上述数据信号至少具备以下有益效果：
(1)由于相较于电力传输的功率，传输的数据信号的功率要小的多，那么在频谱上相当于淹没在电力信号中，这样，即使被窃听者截取，窃听者很有可能会当做噪声信号。所以，通过供电器件3进行数据信号传输，这些数据信号难以被截获，能够提高数据信号传输的安全性。
(2)通过供电器件3传输数据信号，与在光纤信道中传输这些数据信号相比，显然，不占用光纤信道，不会影响到光纤信道中光信号的传输速率。
基于上述所述，该光模块至少具有以下效果：
该光模块不仅具有光电转换功能，还具有实现PoE供电的供电器件，且供电器件未改变光模块原有的结构特征，不影响光模块的尺寸。这样，复合缆的电源连接器通过光模块与通信设备电气连接，复合缆的电源连接器无需插到通信设备中，进而可以节省通信设备的面板空间，有利于通信设备的小型化发展。
该光模块的第一端处的第一电接头31未改变光模块原有的结构特征，使得光模块的第一端具备兼容性，既能供复合缆插入，又能供光缆插入，该光模块的应用场景广泛。
该光模块的第二端处的第二电接头33也未改变光模块原有的结构特征，使得光模块的第二端具备兼容性，既能插入于更新后的光笼子中，又能插入于更新前的光笼子中，该光模块的应用场景广泛。其中，更新后的光笼子也即是与光模块的封装类型相匹配，且包括与第二电接头相匹配的电源连接器的光笼子，更新后的光笼子也即是与光模块的封装类型相匹配，但不包括与第二电接头相匹配的电源连接器的光笼子。光笼子是通信设备的接口部件。
本申请实施例还提供了一种通信设备，该通信设备可以是光通信领域中的任意设备，例如，可以是交换机或者AP等。
如图57并参考图58所示，该通信设备包括机框100、主板200和光电转换组件300；如图57所示，机框100的面板具有光缆插口101，如图58所示的光电转换组件300包括上述所述的光器件2和上述所述的供电器件3；主板200、光器件2和供电器件3均位于机框100中，且光器件2和供电器件3均位于主板200的表面，光器件2的光接头和所述供电器件3的电接头的位置均与光缆插口101的位置相对。
其中，光器件2的光接头用于与复合缆的光纤连接器对接，以实现光信号传输。供电器件3的电接头用于与复合缆的电源连接器电气连接，以实现PoE的电力传输。
在一种示例中，光电转换组件300通过光器件2实现光电转换功能，通过供电器件3实现PoE供电功能。由于该通信设备需要和复合缆连接，故机框100的面板具有光缆插口101，光器件2的光接头的位置和供电器件3的电接头的位置均与光缆插口101的位置相对，例如，光器件2的光接头位于光缆插口101中，供电器件3的电接头也位于光缆插口101中。
在一种示例中，该通信设备可以与复合缆匹配使用，复合缆可以插入到光缆插口101中，复合缆的光纤连接器与光缆插口101中的光器件2的光接头对接，以实现光信号传输，复合缆的电源连接器与光缆插口101中的电接头电气连接，以实现电力传输。
在另一种示例中，光缆插口101具备兼容性，使得该通信设备还可以与光缆匹配使用，光缆的光纤连接器可以插入到光缆插口101中，与光器件2的光接头对接，以实现光信号传输。
可见，该通信设备的光缆插口101，既能匹配复合缆，又能匹配光缆，其具备兼容性，应用场景较为广泛，使用灵活性高，这种通信设备在应用中，也易于现场做线。
其中，通信设备实现兼容性的结构特征可以如下：
其中，光缆插口101具备兼容性的实现方式，可以参见上述，光模块的第一插口11具备兼容性的实现方式。
例如，光器件2的光接头和供电器件3的电接头均位于光缆插口101中，且光器件2的光接头和供电器件3的电接头的位置相互独立，以使光缆插口101用于供复合缆和光缆插入。
在一种示例中，光器件2位于主板200的表面，光器件2的光接头通常通过中柱5支撑，也通过中柱5实现插拔导向限位。供电器件3的电接头的导电部可以固定于中柱5中，而不影响光器件2的光接头处的结构特征。从而能够实现通信设备的光缆插口101具备兼容性。其中，关于供电器件3的电接头的导电部与中柱5之间的固定关系，以及电接头的导电部的具体结构形式，可以参见上述供电器件3的第一电接头导电部311与中柱5的固定关系，以及第一电接头导电部311的具体结构形式，此处不再赘述。
该通信设备的光缆插口101具备兼容性，使得光缆能够插入到光缆插口101中与光缆插口101中的光接头对接，实现光信号传输，复合缆更能插入到光缆插口101中，复合缆的光纤连接器与光缆插口101中的光接头对接，以实现光信号传输，复合缆的电源连接器与光缆插口101中的电接头电气连接，以实现电力传输。
该通信设备集成有光电转换组件300，那么该通信设备与其它设备进行连接中，只需插接光缆或者复合缆，无需额外插接光模块，连接操作简单，能避免光模块的遗失，还能避免因光模块与通信设备的不匹配而出现无法成功连接的情况。
本实施例还提供了一种以太网供电PoE设备，该PoE设备包括上述所述的光模块，该PoE设备的光模块，如上述所述，不仅具有光电转换功能，还具有实现PoE供电的供电器件，且供电器件未改变光模块原有的结构特征，不影响光模块的尺寸。这样，复合缆的电源连接器通过光模块与PoE设备电连接，复合缆的电源连接器无需插到PoE设备中，进而可以节省PoE设备的面板空间，使得PoE设备的结构更加紧凑，有利于PoE设备的小型化发展。
