在本实施例中，该光模块包括：包括收光单元1、微处理器2、发光单元3及设置于所述光模块的光路径的反射单元4；所述微处理器2分别与所述收光单元1及发光单元2连接。
所述反射单元4设置为反射预设频率的入射光并透射所述发光单元发出的发射光。例如，在反射单元4位于朝向入射光入的一侧采用能够反射预设频率入射光的反射层，以使反射单元4反射预设波长的入射光，在反射单元4位于正对发射光入的一侧采用能够透射任意波长发射光的透过层，以使反射单元4透射任意波长的发射光。其中，预设频率与预设波长一一对应，预设频率可以由该反射单元4需要反射的入射光决定。
所述收光单元1设置为接收所述反射单元4反射的入射光，并将接收到的所述入射光的波长信息发送至所述微处理器2；其中，收光单元1在接收到反射单元4反射的入射光时，检测接收的入射光的波长信息。
所述微处理器2，设置为根据接收的波长信息生成光信号生成指令，并发送所述光信号生成指令至发光单元3，所述光信号生成指令中包含发射光的波长信息，且所述发射光的波长与所述入射光的波长不同；当然，微处理器2可以通过获取发光单元3能够发出的光信号的波长信息，然后与接收到的入射光的波长信息与获取的发光单元3能够发出的光信号的波长信息进行比较，确定发射光的波长信息，在发光单元3能够发出波长不同的多种光信号时，发射光的波长信息可以为该多种光信号中除入射光的波长信息之外的其他任意一种波长信息。
所述发光单元3设置为接收所述微处理器发送的光信号生成指令，并根据所述光信号生成指令中的波长信息发出光信号。
可选地，在其他实施例中，如图1所示，所述反射单元4包括至少两个平行设置于所述光模块的光路径中的滤镜41，每个所述滤镜41朝向入射光 的一面设置有反射预设频率的入射光的反射层，所述滤镜41朝向所述发光单元的一面设置有透过所述发射光的透过层，每个所述滤镜41的反射层反射的波长不同。
每个滤镜41平行设置且反射不同波长的入射光，以保证光纤中传输入射光能够经过其中某一个滤镜的反射至收光单元1以被收光单元1接收。
可选地，请参照图1，在其他实施例中，所述收光单元1包括与每个所述滤镜41一一对应的光探测器11，所述光探测器11接收对应的滤镜41反射的入射光，并检测入射光的波长以获取入射光的波长信息。
收光单元1的光探测器11与反射单元4的滤镜41一一对应，使得光探测器11能够准确的检测其对应滤镜41反射的入射光的波长，容易理解，在滤镜41能够反射的光的波长已知时，如果光探测器11检测到其对应滤镜41反射的入射光，则入射光一定包括该波长的光，因此无需光探测器11进行波长的检测而直接确定该光探测器11接收到的光的波长，进而能够减少收光单元1进行入射光波长检测的流程。为便于实现每个所述滤镜41的平面与所述入射光的夹角为45°。
可选地，请参照图1，所述发光单元3包括驱动组件31及发光组件32；所述驱动组件31分别与所述微处理器2及发光组件32连接；所述驱动组件31设置为接收所述微处理器2发送的光信号生成指令，并根据所述光信号生成指令中的波长信息驱动所述发光组件32发出光信号。该光信号为与入射光的波长不同的发射光。
通过驱动组件31驱动发光组件32，能够保证发光单元3运行的稳定性，提高发射光的传输效率。
可选地，光探测器11还设置为检测其对应滤镜41反射的入射光的光功率，收光单元1将光探测器11检测到的第一光功率信息传输至微处理器2，微处理器2还设置为处理第一光功率信息、第二光功率信息、第三光功率信息及第四光功率信息，其中，第二光功率信息为发光组件32的发出光信号的功率、第三光功率信息为收光单元1的对端光模块的收光组件接收的光信号的功率、第四光功率信息为收光单元1的对端光模块的发光组件发出的光信号的功率。微处理器2可以根据接收到的第一光功率信息、第二光功率信息、 第三光功率信息及第四光功率信息计算对应光链路的功率损耗、光信号传输效率或者进行光链路定位等。
本实施例中，通过收光单元1接收反射单元4反射的入射光，微处理器2根据接收的收光单元1发送的波长信息生成光信号生成指令，发光单元3根据接收到的微处理器2发送的光信号生成指令发射与入射光的波长不同的发射光，实现了根据入射光的波长信息控制发光单元3发射与入射光的波长不同的发射光，进而实现发射光与入射光在同一光纤传输，并使得本实施例的光模块能够与任一光模块同时使用，避免了BIDI光模块必须成对使用的限制。
