为使本公开的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本公开进一步详细说明。
相关技术基于单通道光模块，调顶信号的收发路径无法调整。对于如100G\400G客户侧的多通道光模块，面临远端光模块信息不可见的问题。如何合理的使用调顶技术，解决远端光模块管理问题值得研究。
图1为本公开的调顶信号传输控制方法的一些实施例的流程示意图。
在步骤110，第一多通道光模块和第二多通道光模块通过交互，确定用于传输调顶信号的第一通道。
在一些实施例中，第一多通道光模块为位于远端的光模块，第二多通道光模块为位于局端的光模块。
第一通道即为传输调顶信号的主通道。
在步骤120，第一多通道光模块通过第一通道，将光模块信息以调顶信号的方式发送至第二多通道光模块。
在一些实施例中，光模块信息包括OAM(Operation Administration and Maintenance，操作维护管理)信息。
在一些实施例中，远端光模块将OAM信息以成帧的方式通过MCU(Microcontroller Unit，微控制单元)发送给驱动器或者调制器，以低速模拟信号的形式叠加在主路数据业务上，再转换成光信号，将光信号发送至局端光模块。局端光模块将光信号转换成电信号，再经过放大、滤波、限幅的一种或多种电路处理后获得OAM信号，并最终回到MCU，由MCU解析出原始数据。局端光模块在接收到主机端设备发送的读取远端光模块信息的指令后，能够将远端光模块的信息发送至主机端设备，从而使得主机端设备能够完成局端光模块和远端光模块的数据的采集和监控。
在该实施例中，通过两端的多通道光模块的交互，确定一路通道作为传输调顶信号的主通道，然后通过该单一通道将光模块信息传输至对端，能够保证在不影响主路数据业务的同时，实现光模块信息的交互。
图2为本公开的调顶信号传输控制方法的另一些实施例的流程示意图。
在步骤210，第一多通道光模块将携带预配置调顶信号的业务信号，通过多个通道传输至第二多通道光模块。
在一些实施例中，如图3所示，在多通道光模块内部的每个子通道下都配置一套调顶信号的发送和接收处理电路，即调顶电路，由MCU集中控制和调度。在传输光模块信息之前，需要完成调顶通道预配置，选择单个子通道用来传输光模块信息，并且关闭其他通道的调顶电路。
在该步骤中，如图4所示，远端光模块开启每个通道的调顶电路，生成具备一定帧格式的调顶信号用于握手，随业务数据信号一起通过各个通道传输到局端光模块。
在步骤220，第二多通道光模块对业务信号进行分析，选择一路通道作为第一通道，并将第一通道信息以调顶信号的方式发送至第一多通道光模块。
在一些实施例中，局端光模块根据每个通道发送的业务信号，确定每个通道的误码率，并将误码率最小的通道作为第一通道，即作为传输调顶信号的主通道。
例如，光模块内部配有PRBS(Pseudo-Random Binary Sequence，伪随机二进制序列)发送单元和PRBS检测单元。远端光模块传输指定码型的PRBS信号(如PRBS7/PRBS15/PRBS23/PRBS31等)，局端光模块接收并检测这些PRBS信号，并分别计算各通道误码率。其中，两端光模块设置的PRBS信号的码型必须一致，保证误码率计算的准确性。单通道误码率等于通道接收到的错误数据比特数与总接收数据比特数的比值。对于误码率为0的系统，可以增加光纤链路损耗。局端光模块找到误码率最小的一个通道，将该通道作为在调顶信号干扰下性能最优的通道，也是最适合用作接收远端光模块信息的路径。
在一些实施例中，局端光模块将第一通道信息通过第一通道发送至远端光模块，并关闭除第一通道外的其他通道的调顶电路。
在步骤230，第一多通道光模块根据第一通道信息，关闭除第一通道外的其他通道的调顶功能，并以第一通道作为传输调顶信号的主通道。
在一些实施例中，远端光模块通过第一通道接收该第一通道信息，并关闭除第一通道外的其他通道的调顶电路。此时，远端光模块和局端光模块都只保留配对的一个具备调顶功能的通道。
在步骤240，第一多通道光模块通过第一通道，将光模块信息以调顶信号的方式发送至第二多通道光模块。
在上述实施例中，在能够解决远端客户设备或跨专业设备上的多通道光模块信息实时监控问题的基础上，光模块能够择优选择一个通道传输光模块信息，既保证模块整体性能最优，又避免资源过度浪费引起的功耗和成本增加。
图5为本公开的调顶信号传输控制方法的另一些实施例的流程示意图。
在步骤510，第一多通道光模块向第二多通道光模块发送将第一通道切换到第二通道的通道切换请求。
在一些实施例中，在通信正常状态下，远端光模块主动向局端光模块发送切换到第二通道的请求，并开启第二通道的调顶电路。第二通道为除第一通道外的任意一个其他通道。
在步骤520，第二多通道光模块根据通道切换请求，关闭第一通道的调顶功能，并通过第二通道向第一多通道光模块发送通道切换响应。
在一些实施例中，局端光模块接收到通道切换请求后，关闭第一通道的调顶电路，开启第二通道的调顶电路，并通过第二通道向远端光模块发送通道切换响应。
在步骤530，第一多通道光模块接收通道切换响应后，关闭第一通道的调顶功能。
在上述实施例中，在正常工作模式，两端的光模块使用唯一主通道进行调顶信号传输和交换，并且，可以进行通道的主动切换。
图6为本公开的调顶信号传输控制方法的另一些实施例的流程示意图。
在步骤610，第二多通道光模块在第一通道故障或者第一通道的性能参数小于阈值时，向第一多通道光模块发送将第一通道切换到第二通道的通道切换请求。
在一些实施例中，在第一通道故障或性能下降时，局端光模块无法接收到远端光模块发送的光模块信息，因此，向远端光模块发送通道切换请求，其中，可以根据通道误码率，选择性能次优的通道作为切换通道。
在一些实施例中，通道的接收灵敏度下降到不满足指标要求，则说明通道性能下降。
在步骤620，第一多通道光模块通过第二通道向第二多通道光模块发送通道切换响应。
在一些实施例中，远端光模块开启第二通道的调顶电路，并通过该第二通道进行切换响应，同时关闭第一通道的调顶电路。
在步骤630，第二多通道光模块接收通道切换响应后，关闭第一通道的调顶功能。
在该实施例中，当正在工作的调顶通道发生故障或性能下降，导致局端光模块无法接收有效的光模块信息时，局端光模块会分配其他通道的调顶电路，保证光模块信息的继续传输。
图7为本公开的调顶信号传输控制方法的另一些实施例的流程示意图。
在步骤710，第一通道故障时，第一多通道光模块开启各个通道的调顶功能。
在一些实施例中，远端光模块在感知第一通道故障时，会短暂开启各个通道的调顶电路，用于接收请求报文。
在步骤720，第二多通道光模块通过第二通道向第一多通道光模块发送通道切换请求。
在一些实施例中，局端光模块因第一通道故障无法接收远端光模块发送的光模块信息，根据通道误码率，选择性能次优的通道作为第二通道，即备用通道，并通过该备用通道向远端光模块发送切换请求。
在步骤730，第一多通道光模块在发送通道切换响应后，关闭除第二通道外的其他通道的调顶功能。
在一些实施例中，远端光模块接收到切换请求，通过第二通道向局端光模块进行响应，并关闭除第二通道外的其他通道的调顶电路。
在步骤740，第二多通道光模块接收通道切换响应后，关闭第一通道的调顶功能。
在上述实施例中，主调顶通道故障时，局端光模块发送命令报文触发通道切换机制，保证了光模块信息的继续传输。
图8为本公开的调顶信号传输控制方法的另一些实施例的流程示意图。
在步骤810，第一通道的性能参数小于阈值时，第二多通道光模块通过第一通道向第一多通道光模块发送通道切换请求。
在一些实施例中，光模块具备在全生命周期内检测通道的能力，在主调顶通道性能劣化，引起局端光模块无法接收远端光模块发送的信息时，根据通道误码率，选择性能次优的通道作为第二通道，即备用通道。
在步骤820，第一多通道光模块在发送通道切换响应后，关闭第一通道的调顶功能。
在一些实施例中，远端光模块接收到通道切换请求后，开启第二通道的调顶电路，通过该调顶电路发送通过切换请求，并关闭第一通道的调顶电路。
在步骤830，第二多通道光模块接收通道切换响应后，关闭第一通道的调顶功能，完成通道切换。
在上述实施例中，主调顶通道性能劣化时，局端光模块发送命令报文触发通道切换机制，保证了光模块信息的继续传输。
图9为本公开的调顶信号传输控制方法的另一些实施例的流程示意图。
在步骤910，第二多通道光模块在第一通道故障恢复或者第一通道的性能参数大于等于阈值时，通过第二通道向第一多通道光模块发送将第二通道切换到第一通道的通道切换请求。
在一些实施例中，局端光模块感知第一通道故障恢复后，或者，第一通道性能劣化问题恢复后，开启第一通道的调顶电路。
在步骤920，第一多通道光模块通过第一通道向第二多通道光模块发送通道切换响应。

在步骤930，第二多通道光模块接收通道切换响应后，关闭第二通道的调顶功能。
在上述实施例中，在主调顶通道从故障或性能劣化问题恢复时，光模块仍可以沿用原始主通道进行信息发送，从而使得光模块整体性能最优。
