需要说明的是,偏振检测模块可以是偏振光时域反射仪POTDR,,相位偏振检测模块可以是分布式光纤声波传感监测***DAS,,本实施例对其不作具体限定。It should be noted that the polarization detection module may be a polarized light time domain reflectometer POTDR, and the phase polarization detection module may be a distributed optical fiber acoustic wave sensing monitoring system DAS, which is not specifically limited in this embodiment.

需要说明的是,该***平台架构可以为本实施例场景的集中管理单元,或者是网管设备,本实施例对其不作具体限定。It should be noted that the system platform architecture may be a centralized management unit in the scenario of this embodiment, or a network management device, which is not specifically limited in this embodiment.
不同站点之间使用光纤相连。本申请所提到的方法,要求承载收发双向业务的光纤长度相等或者接近。在光传送网(Optical Transport Network,OTN)/密集型光波复用(Dense Wavelength Division Multiplexing,DWDM)网络中,业务为双向的,收发双向业务分别在同缆的两根光纤中分别传输。个别场景下,也存在使用单纤双向同波长的场景,即收发业务在同一根光光纤,使用同一个波长进行正反向同时传输。以上场景可以满足本方案要求的承载收发双向业务的光 纤长度相等或者接近。Different sites are connected using optical fibers. The method mentioned in this application requires that the lengths of optical fibers carrying bidirectional services are equal or close to each other. In an Optical Transport Network (OTN)/Dense Wavelength Division Multiplexing (DWDM) network, services are bidirectional, and bidirectional services are transmitted in two optical fibers on the same cable. In some scenarios, there are also scenarios where a single fiber is used in both directions with the same wavelength, that is, the sending and receiving services are on the same optical fiber and the same wavelength is used for simultaneous forward and reverse transmission. The above scenario can meet the requirements of this solution for optical fiber carrying bidirectional services. The fiber lengths are equal or close to each other.
需要说明的是,应用场景可以根据业务的路径不同,路径上设置的站点不同,也可以根据业务的数量不同,路径的数量也不同,路径的数量为至少两个,本实施例对其不作具体限定。It should be noted that the application scenario can be different according to the path of the service, and the sites set on the path are different. The number of paths can also be different according to the number of services. The number of paths is at least two, which is not specified in this embodiment. limited.
需要说明的是,从光的波动性来考虑,光是一种电磁波,且光矢量与传播方向垂直,一般可以用电矢量来表示光波的光场矢量,在垂直于光传播方向的平面内,光矢量有不同的振动状态,这些状态称为偏振态(State of Polarization,SOP)。当光在光纤中传输的时候,偏振态是不断演化的。光纤的双折射是随机分布的,所以偏振态的变化是随机的。双折射的影响实际上就是使两个线偏振态产生不同的相移。单模光纤的双折射有两种类型,即固有双折射与感生双折射。固有双折射是指光纤在生产过程中产生的双折射,主要由于应力、材料等分布不均匀导致。感生双折射是指来自外界某些物理量变化导致的双折射,例如应力、弯曲、温度、电场、磁场、扭绞等。若两个偏振经历的损耗、光纤时延、色散或者非线性等不相同,则可能改变同一光信号在某一时刻的两个偏振之间的振幅和/相位差,从而导致光信号的偏振态改变。It should be noted that from the perspective of the wave nature of light, light is an electromagnetic wave, and the light vector is perpendicular to the direction of propagation. Generally, the electric vector can be used to represent the light field vector of the light wave. In a plane perpendicular to the direction of light propagation, Light vectors have different vibration states, and these states are called states of polarization (SOP). When light is transmitted in an optical fiber, the polarization state is constantly evolving. The birefringence of optical fiber is randomly distributed, so the change of polarization state is random. The effect of birefringence is actually to produce different phase shifts between the two linear polarization states. There are two types of birefringence in single-mode optical fibers, namely intrinsic birefringence and induced birefringence. Intrinsic birefringence refers to the birefringence produced during the production process of optical fiber, which is mainly caused by uneven distribution of stress, materials, etc. Induced birefringence refers to birefringence caused by changes in certain physical quantities from the outside, such as stress, bending, temperature, electric field, magnetic field, twist, etc. If the loss, fiber delay, dispersion or nonlinearity experienced by the two polarizations are different, the amplitude and/or phase difference between the two polarizations of the same optical signal at a certain moment may be changed, resulting in the polarization state of the optical signal. Change.
偏振光在光纤中传输的过程中,偏振态会不断变化。尤其是光纤环境受到外部因素影响时,偏振态变化速率不同。例如,架空光缆遭遇雷击时,光纤中传输的偏振光的偏振态会因电磁场的急剧变化,产生一个快速的变化。当光缆外部受到震动、敲击时,偏振态也会发生变化。During the transmission of polarized light in optical fibers, the polarization state will continue to change. Especially when the optical fiber environment is affected by external factors, the polarization state changes at different rates. For example, when an overhead optical cable encounters a lightning strike, the polarization state of the polarized light transmitted in the optical fiber will change rapidly due to the rapid change of the electromagnetic field. When the outside of the optical cable is vibrated or knocked, the polarization state will also change.
基于上述***平台架构,下面提出本申请的共用光复用链路确定方法的各个实施例,用于解决上述实施例中的问题。Based on the above system platform architecture, various embodiments of the shared optical multiplexing link determination method of the present application are proposed below to solve the problems in the above embodiments.
如图3所示,图3是本申请一个实施例提供的共用光复用链路确定方法的流程图,本申请实施例的共用光复用链路确定方法可以包括但不限于包括步骤S100、步骤S200、步骤S300和步骤S400。As shown in Figure 3, Figure 3 is a flow chart of a method for determining a shared optical multiplexing link provided by an embodiment of the present application. The method of determining a shared optical multiplexing link according to the embodiment of the present application may include, but is not limited to, steps S100 and S200. , step S300 and step S400.
步骤S100,接收第一路径的第一监测点发送的第一光特性数据变化速率。Step S100: Receive the first optical characteristic data change rate sent by the first monitoring point of the first path.
在一些实施例中,接收所述第一路径的第一监测点发送的第一相位变化速率,所述第一相位变化速率由所述第一监测点通过所述分布式光纤声波传感监测***DAS检测得到;或者,接收所述第一路径的第一监测点发送的第一偏振态变化速率,所述第一偏振态变化速率由所述第一监测点通过所述偏振光时域反射仪POTDR检测得到。In some embodiments, the first phase change rate sent by the first monitoring point of the first path is received, and the first phase change rate is determined by the first monitoring point through the distributed optical fiber acoustic wave sensing monitoring system. DAS detection; or, receiving the first polarization state change rate sent by the first monitoring point of the first path, the first polarization state change rate is determined by the first monitoring point through the polarized light time domain reflectometer POTDR detected.
步骤S200,接收第二路径的第二监测点发送的第二光特性数据变化速率,其中,第一光特性数据变化速率和第二光特性数据变化速率均在变化速率阈值范围内。Step S200: Receive the second optical characteristic data change rate sent by the second monitoring point of the second path, where both the first optical characteristic data change rate and the second optical characteristic data change rate are within the change rate threshold range.
在一些实施例中,接收所述第二路径的第二监测点发送的第二相位变化速率,所述第二相位变化速率由所述第二监测点通过所述分布式光纤声波传感监测***DAS检测得到;或者,接收所述第二路径的第二监测点发送的第二偏振态变化速率,所述第二偏振态变化速率由所述第二监测点通过所述偏振光时域反射仪 POTDR检测得到。In some embodiments, a second phase change rate sent by a second monitoring point of the second path is received, and the second phase change rate is determined by the second monitoring point through the distributed optical fiber acoustic wave sensing monitoring system. DAS detection; or, receiving the second polarization state change rate sent by the second monitoring point of the second path, the second polarization state change rate is determined by the second monitoring point through the polarized light time domain reflectometer POTDR detected.
在一实施例中,通过第一路径的第一监测点的偏振检测模块对第一路径的光缆的第一光特性数据变化速率(第一相位变化速率或者第一偏振态变化速率)进行监测,当监测到的第一光特性数据变化速率在变化速率阈值范围内,证明第一路径上的光缆出现震动事件,那么此时第一监测点会向集中管理单元发送第一光特性数据变化速率;同样的,通过第二路径的第二监测点的偏振检测模块对第二路径的光缆的第二光特性数据变化速率(第二相位变化速率或者第二偏振态变化速率)进行监测,当监测到的第二光特性数据变化速率在变化速率阈值范围内,证明第二路径上的光缆出现震动事件,那么此时第二监测点会向集中管理单元发送第二光特性数据变化速率。In one embodiment, the first optical characteristic data change rate (first phase change rate or first polarization state change rate) of the optical cable of the first path is monitored through the polarization detection module of the first monitoring point of the first path, When the monitored change rate of the first optical characteristic data is within the change rate threshold range, proving that a vibration event occurs in the optical cable on the first path, then the first monitoring point will send the first optical characteristic data change rate to the centralized management unit; Similarly, the second optical characteristic data change rate (second phase change rate or second polarization state change rate) of the optical cable of the second path is monitored through the polarization detection module of the second monitoring point of the second path. If the change rate of the second optical characteristic data is within the change rate threshold range, it proves that a vibration event occurs in the optical cable on the second path. At this time, the second monitoring point will send the second optical characteristic data change rate to the centralized management unit.
需要说明的是,第一网元的偏振检测模块对光缆的偏振态变化速率的监测可以是实时的,也可以是根据预设的时间间隔进行监测,本实施例对其不作具体限定。It should be noted that the polarization detection module of the first network element can monitor the polarization state change rate of the optical cable in real time or according to a preset time interval, which is not specifically limited in this embodiment.
在一实施例中,变化速率阈值是根据历史的施工事件下监测到的多个偏振态变化速率所生成的,当在某一时刻,在光缆上方的地面施工开始,挖掘机、打孔机会对地面进行敲击,从而地面会产生振动,从而会触发光缆中的光纤产生震动,会影响光纤中传输业务的偏振态,从而使得偏振态变化速率出现突变。那么当第一监测点的偏振检测模块监测到的第一路径的光缆的第一光特性数据变化速率在变化速率阈值范围的情况下,说明光缆上方的地面存在施工事件,那么此时会向集中管理单元发送第一光特性数据变化速率;同样的,当第二监测点的偏振检测模块监测到的第二路径的光缆的第二光特性数据变化速率在变化速率阈值范围的情况下,说明光缆上方的地面存在施工事件,那么此时会向集中管理单元发送第二光特性数据变化速率。因此,集中管理单元会接收到第一路径的第一监测点发送的第一光特性数据变化速率和第二路径的第二监测点发送的第二光特性数据变化速率。In one embodiment, the change rate threshold is generated based on multiple polarization state change rates monitored under historical construction events. When at a certain moment, ground construction above the optical cable starts, excavators and drilling machines will Knocking on the ground will cause the ground to vibrate, which will trigger the optical fiber in the optical cable to vibrate, which will affect the polarization state of the transmission service in the optical fiber, causing a sudden change in the polarization state change rate. Then when the change rate of the first optical characteristic data of the optical cable of the first path monitored by the polarization detection module of the first monitoring point is within the change rate threshold range, it means that there is a construction event on the ground above the optical cable, and then the concentration will be concentrated at this time. The management unit sends the first optical characteristic data change rate; similarly, when the second optical characteristic data change rate of the optical cable of the second path monitored by the polarization detection module of the second monitoring point is within the change rate threshold range, it means that the optical cable If there is a construction event on the ground above, the second light characteristic data change rate will be sent to the centralized management unit at this time. Therefore, the centralized management unit will receive the first optical characteristic data change rate sent by the first monitoring point on the first path and the second optical characteristic data change rate sent by the second monitoring point on the second path.
需要说明的是,当某一时刻,光缆被雷击中,此时会产生极强烈的电磁场环境变化,从而影响到光纤中传输业务的偏振态,偏振态会产生快速变化。第一网元和第二网元的偏振检测模块分别在第一时刻和第二时刻检测到偏振态的快速变化,且检测到的第三偏振态变化速率在变化速率阈值范围内范围的最大值,且持续时间小于时间阈值的情况下,不符合外部施工特征,确定为非工程事件,不做处理,不需要记录第一时刻。It should be noted that when an optical cable is struck by lightning at a certain moment, an extremely strong electromagnetic field environment change will occur, which will affect the polarization state of the transmission service in the optical fiber, and the polarization state will change rapidly. The polarization detection modules of the first network element and the second network element detect rapid changes in the polarization state at the first moment and the second moment respectively, and the detected third polarization state change rate is the maximum value within the change rate threshold range. , and if the duration is less than the time threshold, it does not meet the external construction characteristics and is determined to be a non-engineering event.
