技术领域
本申请实施例涉及光纤技术领域，特别涉及一种光纤测试系统、方法、光纤测量管理设备及存储介质。
背景技术
近几年来，光纤宽带迅猛的发展，各种增值业务不断增加，用户的需求也越来越多,这就使得不论是在光网络建设阶段还是在运维阶段，运营商都越来越重视光纤的质量。在光网络建设阶段，运营商会对使用的光缆进行日常维护，定期检测光纤的质量情况，及时主动发现光纤光缆的质量故障。传统的检测方法一般为单方向的测试，在光纤一端发送光源，在发送端接收光反射，根据光反射信息分析光纤的情况，这种方式检测光纤距离短；而为提高检测光纤距离，相关技术中通过在光缆两端分别进行测试并对两次测试的结果进行合并处理。
然而，合并处理需要光纤的总长数据，而光纤的总长数据会根据实际情况实时发生变化，现有的获取光纤总长的方式是通过人工测量的方式进行测量，其中计算时光缆长度数据来源是非实时测量数据，因此，在上述的测试方式中，光纤总长数据是根据前一次人工测量方式获取得到的，具有延时性，从而导致在合并两次测试结果时使用的光纤总长数据与实际情况的光纤总长数据不一致，导致合并结果的误差较大，故障点定位出现偏差，精确度较差。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了 使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
本申请提出的光纤测试系统，在被测光纤的两端均设置有具有反射器的光纤检测设备，可以根据反射器的发生反射的发生时间以及测量光的光速可以实时计算得到被测光纤的总长，从而在合并双向检测的反射数据时，不仅确保了可检测到的光纤长度较长，也使得获得的故障点位置的精确度较高。
本申请的一实施例涉及一种光纤测试系统，本实施例中的光纤测试系统的结构示意图如图1所示，具体包括：第一光纤检测设备101、第二光纤检测设备102、光纤测量管理设备103。
本实施例中，第一光纤检测设备101、第二光纤检测设备102分别设置在被测光纤的两端；第一光纤检测设备101包括第一光源1011、第一反射器1012；第一光源1011、第一反射器1012均分别连接被测光纤的第一端A；第二光纤检测设备102包括第二光源1021、第二反射器1022；第二光源1021、第二反射器1022均分别连接被测光纤的第二端B。
本实施例中，光纤测量管理设备103分别连接第一光纤检测设备101、第二光纤检测设备102；光纤测量管理设备103用于控制第一光源1011、第一反射器1012、第二光源1021、第二反射器1022的开启与关闭；第一光源1011用于向被测光纤的第一端A输入第一测试光，第二反射器1022用于反射第一测试光；第二光源1021用于向被测光纤的第二端B输入第二测试光，第一反射器1012用于反射第二测试光；第一光纤检测设备101还用于接收第一测试光在被测光纤内发生的所有反射事件并汇总得到第一反射信息；第二光纤检测设备102还用于接收第二测试光在被测光纤内发生的所有反射事件并汇总得到第二反射信息。
在第一光纤检测设备101、第二光纤检测设备102设置在被测光纤的两端的情况下，第一光纤检测设备101的第一光源1011以及第一反射器1012分别连接至被测光纤的第一端A，第二光纤检测设备102的第二光源1021以及第二反射器1022分别连接至被测光纤的第二端B。在一次检测的过程中，第一光源1011发出第一测试光，而根据光纤的特性可知，在光纤的每个点均会将测试光反射至第一光纤检测设备101，第一光纤检测设备101会接收到反射光，然而，测试光在沿光纤不断前进的过程中，测试光的功率会逐渐衰减，反射光的功率也会随着测试光行进的距离增加而不断衰减，因此，正常情况下，第一光纤检测设备101的接收到达反射光功率会逐渐衰减的；但是当出现插损、衰减、反射峰值等情况时，反射光的功率会突然增加，此时即可通过反射光功率的波形图定位出存在插损、衰减、反射峰值等情况的具体位置；而当第一测试光到达第二光纤检测设备102的第二反射器1022时，也会将第一测试光反射回去，第二反射器1022的反射会使得反射光的功率增大，第一光纤检测设备101接收到的反射光的波形图会在第二光纤检测设备102处突然加大，即可确定出第二光纤检测设备102到第一光纤检测设备101的距离，得到被测光纤的总长。第二光纤检测设备102发出第二测试光的过程与第一光纤检测设备101的类似，为避免重复，在此不再赘述。
需要说明的是，当测试光在光纤内衰减到一定程度之后，测试光即使到达故障点，返回至第一光纤检测设备101的反射光功率也不会发生明显变化，因此导致单侧检测光纤的距离受限。
如图2所示，为第一光纤检测设备接收的反射光功率与反射点距离的波形图，横轴表示反射点到第一光纤检测设备的距离，纵轴表示反射光的功率。从图中看出，到达C1距离之后，检测不到反射光功率的突然变换，因此，C1点为第一光纤检测设备101能够测量的最大距离，而A1、A2、A3的功率突然增加，表示A1、A2可能为故障点，A3为第二光纤检测设备102的第二反射器1022的反射作用而产生的功率突然变大的现象，因此A3点的距离为第二光纤检测设备102相对于第一光纤检测设备101沿被测光纤上的距离，即被测光纤的长度。
如图3所示，为第二光纤检测设备接收的反射光功率与反射点距离的波形图，横轴表示反射点到第二光纤检测设备的距离，纵轴表示反射光的功率。从图中看出，到达C2距离之后，检测不到反射光功率的突然变换，因此，C2点为第二光纤检测设备102能够测量的最大距离，而B1、B2、B3、B4的功率突然增加，表示B1、B2、B3可能为故障点，B4为第一光纤检测设备101的第一反射器1012的反射作用而产生的功率突然变大的现象，因此B4点的距离为第一光纤检测设备101相对于第二光纤检测设备102沿被测光纤上的距离，即被测光纤的长度。
因此，通过本实施例的光纤测试系统，可以实时根据反射器的发生反射的时间计算得到被测光纤的总长，从而在合并双向检测的反射光数据时，不仅确保了可检测到的光纤长度较长，也使得获得的故障点位置的精确度较高。
在一个实施例中，如图4所示，为本实施例光纤测试系统的结构示意图，本实施例的光纤测试系统相比较上一实施例而言，第一光纤检测设备101包括N个第一端口a，第二光纤检测设备102包括N个第二端口b；一个第一端口a连接被测光纤的第一端A，一个第二端口b连接被测光纤的第二端B；第一光源1011、第一反射器1012均用于可切换地与一个第一端口a连接；第二光源1021、第二反射器1022均用于可切换地与一个第二端口b连接。
本实施例中，第一光纤检测设备101的第一光源1011与多个第一端口a之间设置有单刀多掷开关，使得第一光源1011每次仅与一个第一端口a连接，第一反射器1012与多个第一端口a之间也设置单刀多掷开关，第一反射器1012每次仅与一个第一端口a连接；同理，第二光纤检测设备102的第二光源1021与多个第二端口b之间设置有单刀多掷开关，使得第二光源1021每次仅与一个第二端口b连接，第二射器与多个第二端口b之间也设置单刀多掷开关，第二反射器1022每次仅与一个第二端口b连接。通过此种设置，可以根据需要切换光源与反射器连接的端口，从而实现光纤检测设备仅需一个光源与反射器即可实现切换，使得光纤检测系统可以同时连接多个被测光纤，通过切换光源、反射器进行检测，从而提高检测的效率，同时，也节省了光源与反射器的成本。需要说明的时，除单刀多掷开关的方式之外，还可以通过其他的方式实现光源、反射器对端口的切换，例如通过电子开关管的方式控制端口的连接，本实施例仅是以单刀多掷开关为例进行说明，并不对本实施例的方案进行限制。
在一个实施例中，第一光纤检测设备101、第二光纤检测设备102均为光时域反射仪。本实施例的光时域反射仪(Optical Time Domain Reflectometer，OTDR)能发出测试光至被测光纤，提供反射镜反射被测光纤另一端传输的测试光，还可以接收反射回来的测试光，并与光纤测量管理设备进行通讯，将反射光信息发送给光纤测量管理设备，实现两者之间的数据交互。然而，在实际应用中可以提供光源以及反射镜的其他设备均可以，本实施例仅是限定了其中一种设备，其他能够实现相同功能的设备也在本申请保护的范围之内。
本申请的一实施例涉及一种光纤测试方法，应用于上述实施例的光纤测试系统中的光纤测量管理设备；本实施例中的光纤测试方法的流程示意图如图5所示，具体包括如下步骤：
步骤201，开启第一光源、第二反射器。
本实施例中，光纤测量管理设备将第一光源、第二反射器开启，第一光源、第二反射器开启之后，第一光源向被测光纤的第一端输入第一测试光，第一测试光到达第二光纤检测设备之后，第二反射器反射第一测试光，第一光纤检测设备可以接收第一测试光在被测光纤内发生的所有反射事件并汇总得到第一反射信息。需要说明的是，第一测试光在光纤内传输的过程中会持续发生光反射，第一反射信息包括第一测试光在被测光纤内每次发生反射的信息，包括每次反射光的功率以及时间信息。
步骤202，接收第一光纤检测设备发送的第一反射信息。
步骤203，关闭第一光源、第二反射器，开启第一反射器、第二光源。
本实施例中，光纤测量管理设备接收到第一反射信息后，将第一光源、第二反射器关闭，将第一反射器、第二光源开启，从而使得第二光源向被测光纤的第二端输入第二测试光，第二测试光到达第一光纤检测设备之后，第一反射器反射第二测试光，第二光纤检测设备接收第二测试光在被测光纤内发生的所有反射事件并汇总得到第二反射信息。需要说明的是，第二测试光在光纤内传输的过程中会持续发生光反射，第二反射信息包括第二测试光在被测光纤内每次发生反射的信息，包括每次反射光的功率以及时间信息。
步骤204，根据第一反射信息得到被测光纤的第一计算总长，和/或，根据第二反射信息得到被测光纤的第二计算总长。
本实施例中，本实施例的被测光纤的总长是通过实施计算得到的，在一次测量光发出并反射回至光纤检测设备之后，就可以获取到此时光纤的总长；因此，本实施例可以获取到根据第一反射信息得到被测光纤的第一计算总长，根据第二反射信息得到被测光纤的第二计算总长，第一计算总长与第二计算总长可以仅获取一个，也可以均获取，只要能够获取到此时被测光纤的总长即可。
步骤205，根据第一计算总长或第二计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试参数。
本实施例中，在仅获取第一计算总长的情况下，根据第一计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试结果；在仅获取第二计算总长的情况下，根据第二计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试参数；在获取到第一计算总长、第二计算总长的情况下，可以仅使用第一计算总长、第二计算总长的其中一个将第一反射信息与第二反射信息合并，得到被测光纤的测试参数。
本实施例通过实时获取被测光纤的总长，从而在合并双向检测的反射光数据时，不仅确保了可检测到的光纤长度较长，也使得获得的故障点位置的精确度较高。
不难发现，本实施例是与上一实施例的光纤测试系统相对应的方法实施例，上一实施例的相关技术细节在本实施例中依然有效，在此不再赘述，相应的，本实施例的实施细节也可应用到上一实施例中。
在一个实施例中，在根据第一反射信息得到被测光纤的第一计算总长，和，根据第二反射信息得到被测光纤的第二计算总长之后，还包括：判断第一计算总长与第二计算总长的差 值在预设范围之内；本实施例的具体流程示意图如图6所示，包括以下步骤：
步骤301，开启第一光源、第二反射器。
步骤302，接收第一光纤检测设备发送的第一反射信息。
步骤303，关闭第一光源、第二反射器，开启第一反射器、第二光源。
步骤304，根据第一反射信息得到被测光纤的第一计算总长，和，根据第二反射信息得到被测光纤的第二计算总长。
步骤305，根据第一反射信息得到被测光纤的第一计算总长，或，根据第二反射信息得到被测光纤的第二计算总长。
需要说明的是，步骤304与步骤305是并列的两个步骤，仅执行一个步骤即可；步骤305完成之后，直接进入步骤307；此过程与上一实施例类似，为避免重复，在此不再赘述。
步骤306，判断第一计算总长与第二计算总长的差值是否在预设范围之内。若是，则进入步骤307，若否，则返回步骤301。
本实施例中，在第一计算总长、第二计算总长均获取的情况下，为了提高检测的准确性，通过判断第一计算总长与第二计算总长的差值是否在预设范围之内，判断得到的被测光纤的总长是否有误，若第一计算总长与第二计算总长的差值在预设范围之内，则表示得到的被测光纤的总长无误，若第一计算总长与第二计算总长的差值不再在预设范围之内，则表示得到的被测光纤的总长有误，需要重新进行检测。
步骤307，根据第一计算总长或第二计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试参数。
本实施例的步骤301至步骤303、步骤307与上一实施例的步骤201至步骤203、步骤205相同，为避免重复，在此不再赘述。
在一个实施例中，第一光纤检测设备包括N个第一端口，第二光纤检测设备包括N个第二端口；一个第一端口连接被测光纤的第一端，一个第二端口连接被测光纤的第二端；第一光源、第一反射器均用于可切换地与一个第一端口连接；第二光源、第二反射器均用于可切换地与一个第二端口连接。不难发现，本实施例是与上一实施例的光纤测试系统相对应的方法实施例，上一实施例的相关技术细节在本实施例中依然有效，再此不再赘述，相应的，本实施例的实施细节也可应用到上一实施例中。
本实施例的光纤测试方法的具体流程示意图如图7所示，包括以下步骤：
步骤401，开启第一光源、第二反射器，并将第一光源连接至被测光纤的第一端所连接的第一端口，将第二反射器连接至被测光纤的第二端所连接的第二端口。
本实施例中，本实施例的第一光纤检测设备包括N个第一端口，第二光纤检测设备包括N个第二端口，在一次测试过程中，一个第一端口与一个第二端口对应连接一个被测光纤；因此，本实施例中，在开启第一光源、第二反射器的同时，也需要将第一光源连接至被测光纤连接的第一端口，将第二反射器连接至被测光纤连接的第二端口，从而实现自动化切换。
步骤402，接收第一光纤检测设备发送的第一反射信息。
步骤403，关闭第一光源、第二反射器，开启第一反射器、第二光源，并将第一反射器连接至被测光纤所的第一端所连接的第一端口，将第二光源连接至被测光纤的第二端所连接的第二端口。
本实施例中，在一次测试过程中，一个第一端口与一个第二端口对应连接一个被测光纤； 因此，本实施例中，接收第一光纤检测设备发送的第一反射信息之后，在开启第二光源、第一反射器的同时，也需要将第一反射器连接至被测光纤连接的第一端口，将第二光源连接至被测光纤连接的第二端口，从而实现自动化切换。
步骤404，根据第一反射信息得到被测光纤的第一计算总长，和/或，根据第二反射信息得到被测光纤的第二计算总长。
步骤405，根据第一计算总长或第二计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试参数。
本实施例的步骤402、步骤404至步骤405与上一实施例的步骤202、步骤204至步骤205相同，为避免重复，在此不再赘述。
在一个实施例中，第一反射信息包括有第一光纤检测设备从发送第一测试光到接收第二反射器反射回的第一测试光的第一反射时长；第二反射信息包括有第二光纤检测设备从发送第二测试光到接收第一反射器反射回的第二测试光的第二反射时长；本实施例的流程示意图如图8所示，包括以下步骤：
步骤501，开启第一光源、第二反射器。
步骤502，接收第一光纤检测设备发送的第一反射信息。
步骤503，关闭第一光源、第二反射器，开启第一反射器、第二光源。
步骤504，根据第一反射时长以及第一测试光的光速得到第一计算总长，和/或，根据第二反射时长以及第二测试光的光速得到第二计算总长。
本实施例中，第一反射信息包括有第一光纤检测设备从发送所述第一测试光到接收第二反射器反射回的第一测试光的第一反射时长；第二反射信息包括有第二光纤检测设备从发送第二测试光到接收第一反射器反射回的第二测试光的第二反射时长；而测试光的光速是已知的，因此可以根据第一测试光的光速以及第一反射时长得到第一计算总长，根据第二测试光的光速以及第二反射时长得到第二计算总长，从而获取到被测光纤的总长。
步骤505，根据第一计算总长或第二计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试参数。
本实施例的步骤501至步骤503、步骤505与上一实施例的步骤201至步骤203、步骤205相同，为避免重复，在此不再赘述。
在一个实施例中，如图9所示，为本实施例的具体流程示意图，具体包括以下步骤：
步骤601，开启第一光源、第二反射器。
步骤602，接收第一光纤检测设备发送的第一反射信息。
步骤603，关闭第一光源、第二反射器，开启第一反射器、第二光源。
步骤604，根据第一反射信息得到被测光纤的第一计算总长，和/或，根据第二反射信息得到被测光纤的第二计算总长。
步骤605，根据第一计算总长或第二计算总长将第一反射信息与第二反射信息合并，得到被测光纤的测试参数。
步骤606，判断测试参数与被测光纤的基准参数是否在基准误差范围之内。若是，测试结果为正常，结束流程；若否，测试结果异常，进入步骤607。
本实施例中，测试结果记录有反射光功率突然增加的光纤点的位置信息，在实际应用中，被测光纤可能设置有一些设备，也会导致反射光的功率突然增加，因此，在进行测试之前， 将该部分信息记录在基准参数中，以便工作人员识别故障点和正常点。基准参数的记录需要在光纤建立的最初进行记录，可以根据一些现有的测试方法获取，也可以根据本申请的方式获取，可以根据实际需要设置，本申请不作具体限定。
步骤607，根据测试参数定位出被测光纤的故障点。
本实施例中，当测试结果异常时，将可以根据测试参数与基准参数的区别，识别出哪些是故障点，并将这些故障点的位置定位出来，方便工作人员维修。
需要说明的是，当定位出故障点之后，可以根据故障点的功率大小以及故障的长度预判出故障的类型，从而便于工作人员的维修管理。
本实施例的步骤601至步骤605与上一实施例的步骤201至步骤205相同，为避免重复，在此不再赘述。
