实施例一：
图1示出了本申请实施例提供的第一种光通信模块测试方法的流程示意图，本申请实施例的光通信模块测试方法的执行主体为光通信模块测试装置，该装置优选为包括可视化界面的装置，详述如下：
在S101中，获取光通信模块的编码信息。
光通信模块的编码信息存储在存储单元中，例如光通信模块的EEPROM存储元件中。编码信息一般包括厂商名称、部件号、序列号、生产日期等光通信模块的生产信息，以及封装类型、速率等光通信模块的型号信息。其中，封装类型包括SFP、SFP+、QSFP、QSFP28、SFP、QSFP-DD等，速率包括10Gbit/s、25Gbit/s、50Gbit/s、100Gbit/s、200Gbit/s、400Gbit/s等。
在S102中，根据所述编码信息获取预存的所述光通信模块的最优测试参数，并根据所述最优测试参数调整测试参数配置信息。
不同型号的光通信模块对光通信模块测试装置的条件需求不同，即对光通信模块测试装置的测试参数配置要求不同，其中测试参数可以包括测试接口通信协议模式参数、测试接口发送端的发送电压幅度参数、测试接口发送端的滤波器设置参数、测试接口接收端的接收均衡参数等。对于每种型号的光通信模块，光通信模块测试装置都对应存储一组最优测试参数，可以根据编码信息中的光通信模块的型号信息，通过查询预存在数据库中的型号信息与最优测试参数的对照表，获得最优测试参数，并根据最优测试参数调整光通信测试装置的测试参数配置信息，使得光通信模块测试装置能够提供一个最适合该种型号的光通信模块的测试环境。
在S103中，获取测试模式配置信息，根据所述测试模式配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息，其中所述第一测试结果信息包括光通信模块的误码率。
本实施例中的光通信模块测试模式包括以太网流量测试模式以及伪随机比特流测试模式这两种，测试模式配置信息指定当前的光通信模块测试装置处于哪种测试模式下。以太网流量测试模式下，光通信模块测试装置的以太网流量生成单元生成满速率的以太网报文数据流，通过光通信模块测试装置的测试接口发送端发送给待测的光通信模块；而伪随机比特流模式下，光通信模块测试装置的码型生成单元生成伪随机序列码流，通过光通信测试装置的测试接口发送端发送给待测的光通信模块。可选地，在获取测试模式配置信息，还包括：接收测试模式选择指令，设置测试模式配置信息。
根据当前的测试模式配置信息以及步骤S102中的测试参数的配置，进行光通信模块测试。经过预设的测试时长，可以得到第一测试结果信息，其中第一测试结果信息包括光通信模块的误码率信息。具体地，在测试时，光通信模块测试装置生成的以太网报文数据流或者伪随机序列码流经过测试接口的发送端发送给光通信模块，光通信模块通过自环或者对接的连接模式，将经过光通信模块传输的以太网报文数据流或者伪随机序列码流传回光通信模块测试装置的接收端，光通信模块测试装置通过比较原始生成的以太网报文数据流(或者伪随机序列码)与接收到的经该光通信模块传回的以太网报文数据流（或者伪随机序列码）的数据数量及数据信息内容，得出待测光通信模块的误码率。
可选地，在进行光通信模块测试前，还包括接收测试时长设置指令，设置测试时长。
可选地，在所述S103之后，还包括将所述第一测试结果信息以及当前的测试时间、待测光通信模块的编码信息、测试时长记录存储在数据库中，以便之后对光通信模块测试装置的历史工作信息进行查询。
可选地，在所述光通信模块测试时还包括记录当前环境的温度信息，此时所述第一测试结果包含测试待测光通信模块时的环境温度信息，以便之后分析温度变化对光通信模块测试的影响。
在S104中，根据所述第一测试结果信息及预期结果信息，得出判定结果，其中所述预期结果信息包括预期误码率。
根据第一测试结果信息，例如测试出的待测光通信模块的误码率，与预期结果信息，例如预期误码率，二者相比较，若测试得到的待测光通信模块的误码率小于预期误码率，则判定该待测光通信模块合格。
可选地，上述光通信模块测试方法的整个测试过程都集成于一个光通信模块测试装置。
本申请实施例中，由于通过光通信模块的编码信息自动获取光通信模块的最优测试参数，自动完成繁琐的测试参数配置，并且整个测试过程都集成于一个光通信模块测试装置，因此避免了繁琐的手动操作，大大节省了光通信模块测试过程的时间成本人工成本，提高了光通信模块的测试效率。
实施例二：
图2示出了本申请实施例提供的第二种光通信模块测试方法的流程示意图，本申请实施例的光通信模块测试方法的执行主体为光通信模块测试装置，详述如下：
在S201中，获取光通信模块的编码信息。
本实施例中S201与上一实施例中的S101相同，具体请参阅上一实施例中S101的相关描述，此处不赘述。
可选地，在所述获取光通信模块的编码信息之前，还包括：
若检测到所述光通信模块的编码信息不存在，则接收输入指令，写入所述光通信模块的编码信息。
光通信模块在生产过程中写入编码信息之后再进行测试。若在测试开始时检测不到所述光通信模块的编码信息，说明该光通信模块还未写入编码信息，此时接收输入指令，向该光通信模块写入编码信息。所述编码信息包括厂商名称、部件号、序列号、生产日期等光通信模块的生产信息，封装类型、速率等光通信模块的型号信息，以及光通信模块的运行程序（即向光通信模块写入预设的驱动代码段，以使之后该光通信模块可以执行预期的软件功能）。
在S202中，若检测到所述编码信息对应的光通信模块的最优测试参数不存在，则调校测试参数，确定所述光通信模块的最优测试参数，并存储所述光通信模块的最优测试参数。
如果检测到编码信息对应的光通信模块的最优测试参数不存在，则说明待测光通信模块的型号对应的最优测试参数尚未存储于光通信模块测试装置的数据库中，则需要通过根据当前的光通信模块，进行测试参数调校，从而确定该类型号光通信模块的最优测试参数，并将该最优测试参数存储于数据库中。之后，若与当前的待测光通信模块的型号相同（速率及封装类型相同）的其它光通信模块插入光通信模块测试装置时，便可通过该光通信模块的编码信息获取到该最优测试参数，自动进行装置的测试参数配置。
在调校待测光通信模块的测试参数时，可以将待测光通信模块进行自环连接。自环是指将光通信模块的发送端连接自己的接收端。对于光通信模块中的光模块，可以通过光纤实现自环连接；对于光通信模块中的电模块，可以通过电缆实现自环。测试参数调校时用于自环的光纤或者电缆的长度一般在1米左右。
具体地，所述调校测试参数，确定所述光通信模块的最优测试参数，包括以下步骤：
A1：根据编码信息中的待测光通信模块的速率信息，确定最优测试参数中的测试接口通信协议模式参数。
根据待测光通信模块的编码信息中的速率信息，确定适于该光通信模块的测试接口通信协议模式参数。例如，对于速率为10Gbit/s的光通信模块，其测试接口通信协议模式配置为SFI、XFI；对于速率为25Gbit/s的光通信模块，其测试接口通信协议模式配置为25GAUI、25GBase-C、25GBase-CR-S、 25GBase-CR中的任意一种；对于速率为40Gbit/s的光通信模块，其测试接口通信协议模式配置为XLAUI、XLPPI、40GBase-CR4、XLAUI2中的任意一种；对于速率为50Gbit/s的光通信模块，其测试接口通信协议模式配置为50GAUI-1、50GBase-CR、LAUI-2、50GAUI-2、50GBase-CR2中的任意一种；对于速率为100Gbit/s的光通信模块，其测试接口通信协议模式配置为100GAUI-2、100GBase-CR2、100GAUI-4、100GBase-CR4中的任意一种；对于速率为200Gbit/s的光通信模块，其测试接口通信协议模式配置为200GAUI-4、200GBase-CR4中的任意一种；对于速率为400Gbit/s的光通信模块，其测试接口通信协议模式配置为400GAUI-8、40GBase-CR8中的任意一种。
A2：在预设调参范围内，自动调整测试接口设置参数。
测试接口参数包括测试接口发送端的发送电压幅度参数、测试接口发送端的滤波器设置参数、测试接口接收端的接收均衡参数。对于这几个测试接口参数，都分别对应一个预设调参范围，在预设调参范围内，每次调整时可以根据预设调节步长调整各参数的参数值。
A3：检测测试线路是否形成通路，若没有形成通路，则返回A1检测测试接口通信协议模式参数是否配置正确，返回A2微调测试接口设置参数；否则进入A4。
测试线路是指光通信模块测试装置的测试接口发送端→待测光通信模块→光通信模块测试装置的测试接口接收端，这一整条测试过程的测试信号传输路径。可以通过触发光通信模块测试装置发送一个测试信号，检测该测试信号能否在预设时间内返回光通信模块测试装置，若能够返回，则说明测试线路已形成通路。
A4：采集光通信模块测试装置的测试接口接收端的信号，生成二维的数字眼图；若所述数字眼图符合预期眼图模板，则进入步骤A5，否则返回步骤A2微调测试接口设置参数。
光通信模块测试装置的的测试接口接收端的信号为经过所测光通信模块编码、传输、解码发送回光通信模块测试装置的信号，该信号的质量能够反映出所测光通信模块的质量。根据该信号生成二维的数字眼图，数字眼图需要在特定的装置参数条件下才能正常显示。
A5：获取调校得到的测试接口通信协议模式参数、测试接口设置参数，确定为当前待测光通信模块的一组最优测试参数。
在S203中，根据所述编码信息获取预存的所述光通信模块的最优测试参数，并根据所述最优测试参数调整测试参数配置信息。
本实施例中S203与上一实施例中的S102相同，具体请参阅上一实施例中S102的相关描述，此处不赘述。
在S204中，获取测试模式配置信息，根据所述测试模式配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息，其中所述第一测试结果信息包括光通信模块的误码率。
可选地，所述步骤S204具体包括：
获取测试模式配置信息，若所述测试模式配置信息为以太网流量测试模式，则获取报文配置信息，根据所述报文配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息。
当测试模式配置信息为以太网流量测试模式时，获取预设的报文配置信息，所述报文配置信息设置了以太网流量测试模式下光通信模块测试装置生成的以太网报文数据流的报文头、源MAC地址与目的MAC地址、VLAN ID、报文长度、载荷等信息。可选地，在以太网流量模式测试时，设置满流量全压力测试，例如对于速率为100Git/s的光通信模块，可以对应设置速率为100Git/s的以太网报文数据流，使得光通信模块在满负载的情况下进行测试。根据报文配置信息及S201中配置的测试参数配置信息，生成特定报文格式的以太网报文数据流，在光通信模块自环连接的情况下，经过测试端口的发送端发送给待测光通信模块，经由光通信模块的编码、传输、解码，最终将报文数据通过测试端口的接收端返回给光通信模块测试装置，并将初始生成的以太网报文数据流与返回的以太网报文数据流进行分析比较，得到第一测试结果信息，其中第一测试结果信息包括光通信模块的误码率信息。对于以太网流量测试模式，光通信模块的误码率信息即约为以太网报文数据的传输错误率。具体地，误码率=传输错误率=报文传输错误数÷发送报文总数×100%，其中，报文传输错误数=发送报文总数－接收报文数＋接收到的错误报文数。
可选地，在以太网流量测试模式时，可以在光通信模块测试装置的两个测试接口（第一测试接口及第二测试接口）分别连接一个同型号的光通信模块（第一光通信模块及第二光通信模块），并将这两个光通信模块进行对接，即第一光通信模块的发送端连接第二光通信模块的接收端，第一光通信模块的接收端连接第二光通信模块的发送端（对于光模块通过光纤实现连接，对于电模块通过电缆实现连接）。光通信模块测试装置生成的以太网报文数据流经过第一测试接口的发送端发送给第一光通信模块，第一光通信模块再将该以太网报文数据流发送给第二光通信模块，最终再由第二光通信模块将以太网报文数据流通过第二测试接口的接收端返回光通信模块测试装置。根据光通信模块测试装置连接拓扑关系（即第一测试接口与第二测试接口的对接关系）、发送报文总数、接收报文数、接收到的错误报文数等计算得到传输错误率，将该传输错误率除以2便得到两个对接的光通信模块平均的误码率。
可选地，所述若所述测试模式配置信息为以太网流量测试模式，则获取报文配置信息，根据所述报文配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息，包括：
若所述测试模式配置信息为以太网流量模式，获取前向纠错编码配置信息及报文配置信息，根据所述前向纠错编码配置信息、所述报文配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息。
在以太网流量测试模式下，获取前向纠错编码配置信息，前向纠错编码配置信息包括“打开”及“关闭”两种配置信息，当前向纠错编码配置信息为打开时，开启光通信模块测试装置的前向纠错编码功能，进行光通信模块测试，最终得到第一测试结果信息为进行前向纠错编码情况下的待测光通信模块的误码率；当前向纠错编码配置信息为关闭时，关闭光通信模块测试装置的前向纠错编码功能，进行光通信模块测试，最终得到第一测试结果为反映待测光通信模块原始传输信道质量的原始误码率。
由于光通信模块在实际应用时通常会连接一个前向纠错编码装置，因此开启光通信模块测试装置的前向纠错编码功能，得出待测光通信模块在进行前向纠错编码的情况下的误码率，具有实际的参考价值。
可选地，所述步骤S204具体包括：
获取测试模式配置信息，若所述测试模式配置信息为伪随机比特流测试模式，则获取伪随机序列的多项式常数配置信息，根据所述多项式常数配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息。
当测试模式配置信息为伪随机比特流测试模式时，获取预设的或者用户输入的伪随机序列的多项式常数配置信息，所述伪随机序列的多项式常数配置信息设置了伪随机比特流测试模式下的光通信模块测试装置生成的伪随机序列码的阶数。根据多项式常数配置信息及S201中配置的测试参数配置信息，生成特定的伪随机比特流，在光通信模块自环连接的情况下，经过测试端口的发送端发送给待测光通信模块，经由光通信模块的编码、传输、解码，最终将报文数据通过测试端口的接收端返回给光通信模块测试装置，并进行分析比较，得到第一测试结果信息，其中第一测试结果信息包括光通信模块的误码率信息。对于伪随机比特流测试模式，根据误码数、测试时长及测试速率等信息计算光通信模块的误码率。
在S205    中，根据所述第一测试结果信息及预期结果信息，得出判定结果，其中所述预期结果信息包括预期误码率。
根据第一测试结果信息，例如测试出的待测光通信模块的误码率，与预期结果信息，例如预期误码率，二者相比较，若测试得到的待测光通信模块的误码率小于预期误码率，则判定该待测光通信模块合格。
可选地，所述第一测试结果信息还包括信号眼图，此时所述预期结果信息还包括预期眼图模板。
在光通信模块测试时，通过采集测试接口的接收端接收的信号生成信号眼图，根据该信号眼图可以定性判断测试接口的接收端接收的信号质量，从而反映出所测光通信模块的质量。此时预期结果信息还包括预期眼图模板，若第一测试结果中包含的测试出的待测光通信模块的误码率小于预期误码率，并且第一测试结果中包含的信号眼图符合预期眼图模板，则判定该待测光通信模块合格。
可选地，在所述根据所述第一测试结果信息及预期结果信息，得出判定结果之后，还包括：
将测试信息存入数据库，其中所述测试信息至少包括所述光通信模块的编码信息、第一测试结果信息及判定结果。
光通信模块测试装置集成了数据库，在光通信模块进行测试后，将光通信模块的编码信息、第一测试结果信息及判定结果等测试信息存入数据库，以便之后对光通信模块测试装置的历史工作信息进行查询。可选地，所述测试信息还可以包括当前的测试时间点、测试时长、测试参数配置信息、当前的测试环境温度等信息。
本申请实施例中，由于通过光通信模块的编码信息自动调校光通信模块的测试参数并且进行存储，使得对于一种型号的光通信模块至多只需进行一次完整的参数调校便可使之后的测试能直接获得该型号的光通信模块对应的最优测试参数，自动根据该最优参数进行相关测试参数调整，进一步提高了光通信模块的测试效率。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。

该光通信模块测试装置包括：若干个测试接口31、第一获取单元32、测试参数配置单元33、测试单元34、判定单元35，这些单元与接口集成在一个光通信模块测试装置中。其中：
若干个测试接口31，用于与一个或多个光通信模块连接。
本申请实施例的光通信模块测试装置可以同时测试多个光通信模块，例如可以同时测试32个光通信模块或者同时测试128个光通信模块，每个光通信模块的测试方法流程都如实施例一或者实施例二中所述的光通信模块测试方法所述。
第一获取单元32，用于获取光通信模块的编码信息。
光通信模块的编码信息存储在存储单元中，例如光通信模块的EEPROM存储元件中。编码信息一般包括厂商名称、部件号、序列号、生产日期等光通信模块的生产信息，以及封装类型、速率等光通信模块的型号信息。其中，封装类型包括SFP、SFP+、QSFP、QSFP28、SFP、QSFP-DD等，速率包括10Gbit/s、25Gbit/s、50Gbit/s、100Gbit/s、200Gbit/s、400Gbit/s等。
可选地，所述光通信模块测试装置还包括编码单元，用于若检测到所述光通信模块的编码信息不存在，则接收输入指令，写入所述光通信模块的编码信息。
可选地，所述光通信模块测试装置还包括测试参数调校单元，用于若检测到所述编码信息对应的光通信模块的最优测试参数不存在，则调校测试参数，确定所述光通信模块的最优测试参数，并存储所述光通信模块的最优测试参数。
测试参数配置单元33，用于根据所述编码信息获取预存的所述光通信模块的最优测试参数，并根据所述最优测试参数调整测试参数配置信息。
不同型号的光通信模块对光通信模块测试装置的条件需求不同，即对光通信模块测试装置的测试参数配置要求不同，其中测试参数可以包括测试接口通信协议模式参数、测试接口发送端的发送电压幅度参数、测试接口发送端的滤波器设置参数、测试接口接收端的接收均衡参数等。对于每种型号的光通信模块，光通信模块测试装置都对应存储一组最优测试参数，可以根据编码信息中的光通信模块的型号信息，通过查询预存在数据库中的型号信息与最优测试参数的对照表，获得最优测试参数，并根据最优测试参数调整光通信测试装置的测试参数配置信息，使得光通信模块测试装置能够提供一个最适合该种型号的光通信模块的测试环境。
测试单元34，用于获取测试模式配置信息，根据所述测试模式配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息，其中所述第一测试结果信息包括光通信模块的误码率。
本实施例中的光通信模块测试模式包括以太网流量测试模式以及伪随机比特流测试模式这两种，测试模式配置信息指定当前的光通信模块测试装置处于哪种测试模式下。以太网流量测试模式下，光通信模块测试装置的以太网流量生成单元生成满速率的以太网报文数据流，通过光通信模块测试装置的测试接口发送端发送给待测的光通信模块；而伪随机比特流模式下，光通信模块测试装置的码型生成单元生成伪随机序列码流，通过光通信测试装置的测试接口发送端发送给待测的光通信模块。可选地，在获取测试模式配置信息，还包括：接收测试模式选择指令，设置测试模式配置信息。
根据当前的测试模式配置信息以及测试参数配置信息，进行光通信模块测试。经过预设的测试时长，可以得到第一测试结果信息，其中第一测试结果信息包括光通信模块的误码率信息。具体地，在测试时，光通信模块测试装置生成的以太网报文数据流或者伪随机序列码流经过测试接口的发送端发送给光通信模块，光通信模块通过自环或者对接的连接模式，将经过光通信模块传输的以太网报文数据流或者伪随机序列码流传回光通信模块测试装置的接收端，光通信模块测试装置通过比较原始生成的以太网报文数据流(或者伪随机序列码)与接收到的经该光通信模块传回的以太网报文数据流（或者伪随机序列码）的数据数量及数据信息内容，得出待测光通信模块的误码率。
可选地，所述测试单元34包括:
第一测试单元，用于获取测试模式配置信息，若所述测试模式配置信息为以太网流量测试模式，则获取报文配置信息，根据所述报文配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息。
可选地，所述测试单元34包括：
前向纠错编码测试单元，用于若所述测试模式配置信息为以太网流量模式，获取前向纠错编码配置信息及报文配置信息，根据所述前向纠错编码配置信息、所述报文配置信息及所述测试参数配置信息进行光通信模块测试，得到第一测试结果信息。
可选地，所述测试单元34包括：

判定单元35，用于根据所述第一测试结果信息及预期结果信息，得出判定结果，其中所述预期结果信息包括预期误码率。
根据第一测试结果信息，例如测试出的待测光通信模块的误码率，与预期结果信息，例如预期误码率，二者相比较，若测试得到的待测光通信模块的误码率小于预期误码率，则判定该待测光通信模块合格。
可选地，所述第一测试结果信息还包括信号眼图，此时所述预期结果信息还包括预期眼图模板。
可选地，所述光通信模块测试装置还包括：
测试时长设置单元，用于接收测试时长设置指令，设置测试时长。
可选地，所述光通信模块测试装置还包括：
数据库，用于存入测试信息，其中所述测试信息至少包括所述光通信模块的编码信息、第一测试结果信息及判定结果，以便之后对光通信模块测试装置的历史工作信息进行查询。可选地，所述测试信息还可以包括当前的测试时间点、测试时长、测试参数配置信息、当前的测试环境温度等信息。
可选地，所述光通信模块测试装置还包括：
温度监测单元，用于记录当前环境的温度信息。
可以将光通信模块放置于温度处于变化状态的环境中，此时所述第一测试结果包含测试待测光通信模块时的环境温度信息，以便之后分析温度变化对光通信模块测试的影响。
本申请实施例中，由于通过光通信模块的编码信息自动获取光通信模块的最优测试参数，自动完成繁琐的测试参数配置，并且整个测试过程都集成于一个光通信模块测试装置，因此避免了繁琐的手动操作，大大节省了光通信模块测试过程的时间成本人工成本，提高了光通信模块的测试效率。
