Description

BOSA接收功率校准方法及装置
本申请要求在2019年12月24日提交中国专利局、申请号为201911351226.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及微电子领域，例如，涉及一种双向光学子系统(Bi-directional Optical Sub-Assembly，BOSA)接收功率校准方法及装置。
背景技术
随着光纤通信技术的发展和核心网以及接入网的建设，为实现光纤到户(Fibre To The Home，FTTH)的全网光纤化，无源光纤网络(Passive Optical Network，PON)已不断展现向终端用户提供可靠的数据、语音和视频通信的能力。PON技术中，千兆位无源光纤网络(Gigabit Passive Optical Network，GPON)和以太网无源光网络(Ethernet Passive Optical Network，EPON)是两种主流的高效宽带接入技术。
上述PON技术的实现可采用PON单板，对PON单板而言，其可通过搭载BOSA以实现与光纤线路终端(Optical Line Terminal，OLT)相连接。BOSA的设置代替了传统的光模块方案，去掉外壳和控制芯片降低了单板成本，也提高了单板的性能。由于BOSA直接设置为与OLT连接，因此，BOSA的接收性能则直接影响着光通信业务质量的高低。
BOSA内部设置有一个光电雪崩二极管(Avalanche Photon Diode，APD)；对于使用板载BOSA的PON单板，需要为BOSA提供一个升压电路模块，由于升压电路的使用，则需要对BOSA中的APD的温度查找表，即根据不同温度与该APD对应输出的光电流数值之间的映射关系的记录进行温度补偿，上述温度补偿的过程即为对BOSA接收功率的校准。
相关技术中，进行BOSA接收功率的校准的过程中，通常采用二点确定或三点确定的方法，以建立BOSA接收功率校准的模型，进而对BOSA接收功率进行校准。但上述BOSA接收功率校准的模型建立过程中，往往会由于模型建立中的诸多因素考量不全面而导致BOSA接收功率校准模型与实际情况并不相符，进而造成BOSA接收功率校准的准确性较低。

具体实施方式
下文中将参考附图并结合实施例来说明本申请。
本申请中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
本实施例提供了一种BOSA接收功率校准方法，图1是本申请实施例提供的一种BOSA接收功率校准方法的流程图，如图1所示，本实施例中的BOSA接收功率校准方法包括：
S102，根据BOSA参数信息确定校准类型。
S104，根据以下对象确定校准参数：校准类型、第一采样信息、第二采样信息；其中，第一采样信息用于指示预设的采样点中测量的测量ADC信息，第二采样信息用于指示预设的采样点对应的接收光功率信息。
S106，根据校准参数确定光功率信息与ADC信息之间的关系，并根据光功率信息与ADC信息之间的关系进行BOSA接收功率校准。
上述实施例中，步骤S102中的BOSA参数信息为BOSA中的固有信息，可通过查询BOSA的相关硬件或软件信息，如BOSA驱动芯片手册等，以获取上述BOSA参数信息，进而确定校准类型。上述校准类型用以指示光功率信息与ADC信息之间的关系的类型，可以为，在光功率信息与ADC信息之间的函数模型中所对应的模型的函数类型，如二次函数模型、三次函数模型等。
上述实施例中，步骤S104中的ADC信息用于指示BOSA中由APD输出的光功率值所转换为的电信号的输出值，具体实施过程中，可直接读取BOSA驱动芯片对应设置的图形用户界面(Graphical User Interface，GUI)软件测量所得的BOSA接收光功率对应的ADC值，以作为上述实施例中的ADC信息。对应的，上述实施例中的第一采样信息即为在一个或多个采用点所获取的APD输出的光功率值所转换为的电信号的输出值。
步骤S104中的光功率信息用于指示通过光功率监控设备，如光功率计等，对上述实施例中的APD的实际光功率值进行直接测量所得到的光功率值。对应的，上述实施例中的第二采样信息即为在一个或多个采用点所获取的光功率监控设备接收到的实际光功率值。
上述实施例中的第一采样信息以及第二采样信息中的采用点为一一对应的关系。
步骤S104中，校准参数可以为光功率信息与ADC信息之间的函数模型的模型参数，也可理解为函数模型的函数系数；在得到第一采样信息以及第二采样信息的基础上，可以通过拟合等计算方式，以确定上述校准参数。校准参数可以包括多个方面，如在光功率信息与ADC信息之间的函数模型中所对应的一个或多个位置，以及在该位置的对应数值；校准参数的数量及位置可由步骤S102中的校准类型进行确定。
上述实施例中，步骤S106中，在确定校准参数的基础上，即可得到光功率信息与ADC信息之间的关系，例如，光功率信息与ADC信息之间的函数模型，以此，即可进行BOSA接收功率的校准。
通过本实施例中的BOSA接收功率校准方法，由于可根据BOSA参数信息确定校准类型；并根据以下对象确定校准参数：所述校准类型、第一采样信息、第二采样信息；其中，所述第一采样信息用于指示预设的采样点中测量的测量ADC信息，所述第二采样信息用于指示预设的采样点对应的接收光功率信息；从而根据所述校准参数确定光功率信息与ADC信息之间的关系，并根据所述光功率信息与ADC信息之间的关系进行BOSA接收功率校准。因此，本实施例中的BOSA接收功率校准方法可以解决相关技术中BOSA接收功率校准过程中，由于未能对于可能影响光功率信息和ADC信息的因素全面考量而导致BOSA接 收功率校准不准确的问题，以达到有效改善BOSA接收功率校准的准确性的问题。
通过上述实施例中的BOSA接收功率校准方法，首先根据BOSA参数信息对BOSA接收功率校准过程中，光功率信息与ADC信息之间的关系进行了类型的初步确定，以明确作为校准对象的BOSA中APD对应的光功率信息与ADC信息之间的函数模型的类型；在此基础上，通过第一采样信息以及第二采样信息的采样方式以确定光功率信息与ADC信息之间的函数模型所对应的参数或系数，从而建立了光功率信息与ADC信息之间精确的函数模型。以上述模型作为BOSA接收功率校准的模型以进行BOSA接收功率校准，即可改善准确性。
另一方面，本实施例中的BOSA接收功率校准方法不限于板载BOSA对应的单板类型，具有较好的适用性。
在一可选实施例中，上述步骤S102中，根据BOSA参数信息确定校准类型之前，还包括：
获取BOSA中预设的寄存器的类型信息；根据寄存器的类型信息，确定BOSA参数信息。
上述BOSA中寄存器的类型信息为BOSA的固有信息，可通过查询BOSA的相关硬件或软件信息，如BOSA驱动芯片手册等，以获取上述寄存器的类型信息；寄存器的类型信息可以指示APD对应的寄存器个数以及寄存器类型等相关信息，以此，即可根据寄存器的类型信息直接作为BOSA参数信息，以实现BOSA参数信息的确定。
在一可选实施例中，上述步骤S104中，根据以下对象确定校准参数：校准类型、第一采样信息、第二采样信息，包括：
根据以下对象获取拟合光功率信息：校准类型、第一采样信息、第二采样信息；其中，拟合光功率信息用于指示在预设的采样点进行拟合处理所得到的光功率信息；根据拟合光功率信息以及接收光功率信息，确定校准参数。
上述可选实施例中，拟合光功率信息即指示在根据第一采样信息以及第二采样信息以进行拟合过程中，在一个或多个预设的采用点所对应的光功率的拟合值，该拟合值可以通过最小二乘法拟合得到。根据多个采用值进行拟合以得到对应的拟合值的过程为本领域技术人员已知的，故在此不再赘述。
由于拟合的过程中所得到的拟合值具有不唯一性，即拟合值是在一定幅度内变化的，对应的，由多个拟合值所构成的拟合曲线也会在一定幅度内变化。对此，上述可选实施例中，在经过拟合后得到拟合光功率信息后，可根据接收光功率信息对拟合光功率信息进行选择，以得到唯一的校准参数，以建立光功 率信息与ADC信息之间的函数模型。
在一可选实施例中，上述根据拟合光功率信息以及接收光功率信息，确定校准参数，包括：
确定校准数值，其中，校准数值为采样点中的拟合光功率信息与对应的采样点中的接收光功率信息之间的误差为极小值的情形下，校准参数的数值；根据校准类型与校准数值确定校准参数。
上述可选实施例中，校准数值用于指示校准参数在光功率信息与ADC信息之间的函数模型中对应位置的数值；由于拟合光功率信息的不唯一性，采用不同的拟合光功率信息即可得到不同的光功率信息与ADC信息之间的函数模型，以对应不同的校准参数；上述可选实施中，在多个拟合光功率信息中采用拟合光功率信息与对应的采样点中的接收光功率信息之间的误差为极小值的情形下对应的拟合光功率信息以建立光功率信息与ADC信息之间的函数模型，在该模型下对应的校准参数的对应数值即为校准数值。
在一可选实施例中，上述步骤S102中，根据BOSA参数信息确定校准类型之前，还包括：
获取温度信息与APD的DAC信息之间的对应关系，其中，APD的DAC信息用于指示APD在对应的温度信息指示的温度中进行工作的控制信息；根据温度信息与DAC信息的对应关系，确定工作温度信息对应的DAC信息，其中，工作温度信息用于指示BOSA的工作温度。
上述可选实施例中，控制信息用于指示APD在不同的温度环境所对应的驱动电压/电流，用以驱动APD在对应的温度环境下正常工作；基于此，上述获取温度信息与APD的DAC信息之间的对应关系，即确定在不同温度信息下，可驱动APD进行正常工作的DAC信息。以此，即可确定BOSA的当前工作温度，即工作温度信息下APD可进行正常工作的DAC信息，以对APD进行驱动。
上述APD在不同温度信息下对应的DAC信息可称为APD的温度查找表；通常而言，相关技术中在板载BOSA对应的单板上电时，通过BOSA驱动芯片对应的GUI软件以烧录预设的APD的温度查找表。然而，单板中PCB材质或加工工艺，以及BOSA器件或芯片选型或加工工艺等均有可能对于APD的光电效应造成影响；即不同型号的单板，乃至同一型号的单板中APD的光电效应，即APD中温度信息与DAC信息的实际对应关系均有可能出现差异。
因此，上述由APD或单板制造方或使用方预设的APD的温度查找表往往会存在一定的误差，表现为一温度信息下，APD温度查找表中对应的DAC信息并不能实现APD的正常驱动，进而造成APD的工作效果不佳的同时，对后续 的BOSA的接收功率校准亦会产生影响。
基于此，上述可选实施例可通过在进行BOSA的接收功率校准前，重新确定APD的温度信息与DAC信息的对应关系，以对APD的温度查找表进行了校准，从而克服了上述APD的光电效应受单板间差异的影响，使得在BOSA当前的工作温度下可通过重新确定过的DAC信息以确保APD正常工作，以在改善BOSA整体工作的稳定性的同时，令本实施例中的BOSA接收功率校准的准确性得以改善。
在一可选实施例中，上述获取温度信息与APD的DAC信息之间的对应关系，包括：
获取温度信息与APD的初始DAC信息之间的对应关系；其中，APD的初始DAC信息用于指示APD在对应的温度信息指示的温度中理论进行工作的控制信息；根据温度信息与初始DAC信息的对应关系，获取温度信息与APD的实际DAC信息之间的对应关系；其中，APD的实际DAC信息用于指示APD在对应的温度信息指示的温度中，在BOSA中实际进行工作的控制信息。
根据温度信息与DAC信息的对应关系，确定工作温度信息对应的DAC信息，包括：
根据温度信息与实际DAC信息的对应关系，获取工作温度信息对应的实际DAC信息，确定工作温度信息对应的DAC信息。
上述APD的初始DAC信息即指示预设的APD温度查找表中，一温度信息下所对应的DAC信息，即未对于APD温度查找表进行校准前的DAC信息。对应的，上述APD的实际DAC信息即为一温度信息下，可实际驱动APD进行正常工作的DAC信息，即校准后的APD温度查找表中的DAC信息。
在一可选实施例中，上述根据温度信息与初始DAC信息的对应关系，获取温度信息与APD的实际DAC信息之间的对应关系，包括：
根据温度信息与初始DAC信息的对应关系，获取温度信息对应的APD的第一初始DAC信息与第二初始DAC信息；其中，第一初始DAC信息用于指示APD在温度信息指示的温度中正常工作的DAC信息，第二初始DAC信息用于指示APD在温度信息指示的温度中临界发光的DAC信息；根据BOSA的工作电压，确定工作温度信息对应的第一初始DAC信息与第二初始DAC信息之间的目标差值；选取目标温度信息对应的第一初始DAC信息与第二初始DAC信息，其中，目标温度信息对应的第一初始DAC信息与第二初始DAC信息之间的差值符合目标差值；将目标温度信息对应的初始DAC信息配置为工作温度信息对应的实际DAC信息，以获取温度信息与实际DAC信息之间的对应关系。
在一可选实施例中，本实施例中的方法还包括：
输入测试光至外部的光功率测量单元以获取第一光功率信息，其中，第一光功率信息为光功率测量单元对测试光进行测量得到的光功率信息；输入测试光至BOSA以获取第二光功率信息，其中，第二光功率信息为BOSA输出的测试光的光功率信息；获取第一光功率信息与第二光功率信息的关系。
上述光功率测量单元独立于本实施例中的BOSA，即通过光功率测量单元以及BOSA针对同一测试光所分别得到的第一光功率信息与第二光功率信息之间的比较结果，以对上述实施例中的光功率信息以及ADC信息之间建立的函数模型的准确性进行验证。
在一可选实施例中，上述获取第一光功率信息与第二光功率信息的关系之后，还包括：
在第一光功率信息与第二光功率信息的差值小于或等于预设的误差阈值的情形下，根据光功率信息与ADC信息之间的关系进行BOSA接收功率校准；或者，在第一光功率信息与第二光功率信息的差值大于预设的误差阈值的情形下，执行以下操作：获取温度信息与APD的DAC信息之间的对应关系，并根据温度信息与DAC信息的对应关系确定工作温度信息对应的DAC信息；所述根据BOSA参数信息确定校准类型；根据以下对象确定校准参数：所述校准类型、第一采样信息、第二采样信息；其中，所述第一采样信息用于指示预设的采样点中测量的测量ADC信息，所述第二采样信息用于指示预设的所述采样点对应的接收光功率信息；根据所述校准参数确定光功率信息与ADC信息之间的关系，并根据所述光功率信息与所述ADC信息之间的所述关系进行BOSA接收功率校准。
上述可选实施例中，在第一光功率信息与第二光功率信息的差值大于预设的误差阈值的情形下，即确定光功率信息以及ADC信息之间建立的函数模型的准确性较低，故可重新进行APD的温度查找表的校准，并在此基础上，重新建立光功率信息以及ADC信息之间函数模型。以此往复，即可使得最终建立的光功率信息以及ADC信息之间函数模型的准确性得以改善。
为说明本实施例中的BOSA接收功率的校准方法，以下通过具体实施例的方式进行说明。
具体实施例

S2，针对单板间的差异对于上述S1中的初始APD温度查找表进行校准处理。方式为，通过BOSA驱动芯片GUI软件确定单板当前的工作温度下APD临界发光时的APD_DAC值(即上述实施例中的初始DAC值)，通过温度补偿的方式重新确定APD温度查找表中温度与APD_DAC值之间的对应关系，以使得APD温度查找表中当前工作温度环境对应的APD_DAC值为可令APD正常工作的APD_DAC值。

通过以上的实施方式的描述，根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，也可以通过硬件。本申请的技术方案本质上可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如只读存储器(Read-Only Memory，ROM)/随机存取存储器(Random Access Memory，RAM)、磁碟、光盘)中，包括多个指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请实施例所述的方法。
实施例2
本实施例提供了一种BOSA接收功率校准方法，图5是本申请实施例提供的另一种BOSA接收功率校准方法的流程图，如图5所示，本实施例中的BOSA接收功率校准方法包括：
S202，获取温度信息与APD的DAC信息之间的对应关系，其中，APD的DAC信息用于指示APD在对应的温度信息指示的温度中进行工作的控制信息。
S204，根据温度信息与DAC信息的对应关系，确定工作温度信息对应的DAC信息，其中，工作温度信息用于指示BOSA的工作温度。
S206，根据工作温度信息对应的DAC信息，确定光功率信息与ADC信息之间的关系，并根据光功率信息与ADC信息之间的关系进行BOSA接收功率校准。
上述可选实施例中，控制信息用于指示APD在不同的温度环境所对应的驱动电压/电流，用以驱动APD在对应的温度环境下正常工作；基于此，上述获取温度信息与APD的DAC信息之间的对应关系，即确定在不同温度信息下，可驱动APD进行正常工作的DAC信息。以此，即可确定BOSA的当前工作温度，即工作温度信息下APD可进行正常工作的DAC信息，以对APD进行驱动。
上述APD在不同温度信息下对应的DAC信息可称为APD的温度查找表；通常而言，相关技术中在板载BOSA对应的单板上电时，通过BOSA驱动芯片对应的GUI软件以烧录预设的APD的温度查找表。然而，单板中PCB材质或加工工艺，以及BOSA器件或芯片选型或加工工艺等均有可能对于APD的光电效应造成影响；即不同型号的单板，乃至同一型号的单板中APD的光电效应，即APD中温度信息与DAC信息的实际对应关系均有可能出现差异。
因此，上述由APD或单板制造方或使用方预设的APD的温度查找表往往会存在一定的误差，表现为一温度信息下，APD温度查找表中对应的DAC信息并不能实现APD的正常驱动，进而造成APD的工作效果不佳的同时，对后续的BOSA的接收功率校准亦会产生影响。
基于此，上述可选实施例可通过在进行BOSA的接收功率校准前，重新确定APD的温度信息与DAC信息的对应关系，以对APD的温度查找表进行了校准，从而克服了上述APD的光电效应受单板间差异的影响，使得在BOSA当前的工作温度下可通过重新确定过的DAC信息以确保APD正常工作，以在改善BOSA整体工作的稳定性的同时，令本实施例中的BOSA接收功率校准的准确性得以改善。
在一可选实施例中，上述步骤S202中，获取温度信息与APD的DAC信息之间的对应关系，包括：
获取温度信息与APD的初始DAC信息之间的对应关系；其中，APD的初始DAC信息用于指示APD在对应的温度信息指示的温度中理论进行工作的控制信息；根据温度信息与初始DAC信息的对应关系，获取温度信息与APD的实际DAC信息之间的对应关系；其中，APD的实际DAC信息用于指示APD在对应的温度信息指示的温度中，在BOSA中实际进行工作的控制信息。
根据温度信息与DAC信息的对应关系，确定工作温度信息对应的DAC信息，包括：
根据温度信息与实际DAC信息的对应关系，获取工作温度信息对应的实际DAC信息，确定工作温度信息对应的DAC信息。
上述APD的初始DAC信息即指示预设的APD温度查找表中，一温度信息下所对应的DAC信息，即未对于APD温度查找表进行校准前的DAC信息。对应的，上述APD的实际DAC信息即为一温度信息下，可实际驱动APD进行正常工作的DAC信息，即校准后的APD温度查找表中的DAC信息
在一可选实施例中，上述根据温度信息与初始DAC信息的对应关系，获取温度信息与APD的实际DAC信息之间的对应关系，包括：
根据温度信息与初始DAC信息的对应关系，获取温度信息对应的APD的第一初始DAC信息与第二初始DAC信息；其中，第一初始DAC信息用于指示APD在温度信息指示的温度中正常工作的DAC信息，第二初始DAC信息用于指示APD在温度信息指示的温度中临界发光的DAC信息；根据BOSA的工作电压，确定工作温度信息对应的第一初始DAC信息与第二初始DAC信息之间的目标差值；选取目标温度信息对应的第一初始DAC信息与第二初始DAC信息，其中，目标温度信息对应的第一初始DAC信息与第二初始DAC信息之间的差值符合目标差值；将目标温度信息对应的初始DAC信息配置为工作温度信息对应的实际DAC信息，以获取温度信息与实际DAC信息之间的对应关系。
在一可选实施例中，本实施例中的方法还包括：
输入测试光至外部的光功率测量单元以获取第一光功率信息，其中，第一光功率信息为光功率测量单元对测试光进行测量得到的光功率信息；输入测试光至BOSA以获取第二光功率信息，其中，第二光功率信息为BOSA输出的测试光的光功率信息；获取第一光功率信息与第二光功率信息的关系。
上述光功率测量单元独立于本实施例中的BOSA，即通过光功率测量单元以及BOSA针对同一测试光所分别得到的第一光功率信息与第二光功率信息之间的比较结果，以对上述实施例中的光功率信息以及ADC信息之间建立的函数模型的准确性进行验证。
在一可选实施例中，上述获取第一光功率信息与第二光功率信息的关系之后，还包括：
在第一光功率信息与第二光功率信息的差值小于或等于预设的误差阈值的情形下，根据光功率信息与ADC信息之间的关系进行BOSA接收功率校准；或者，在第一光功率信息与第二光功率信息的差值大于预设的误差阈值的情形下， 执行获取温度信息与APD的DAC信息之间的对应关系，并根据温度信息与DAC信息的对应关系确定工作温度信息对应的DAC信息的操作。
上述可选实施例中，在第一光功率信息与第二光功率信息的差值大于预设的误差阈值的情形下，即确定光功率信息以及ADC信息之间建立的函数模型的准确性较低，故可重新进行APD的温度查找表的校准。以此往复，即可使得最终建立的光功率信息以及ADC信息之间函数模型的准确性得以改善。
通过以上的实施方式的描述，根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，也可以通过硬件。本申请的技术方案本质上可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括多个指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请实施例所述的方法。
