Technical Field

The present disclosure relates to the field of optical communications, and in particular, to an optical fiber monitoring method, apparatus, device, and storage medium.

Background

The optical fiber may be a fiber made of glass or plastic, referred to as an optical fiber for short. The optical cable can be formed by a plurality of optical fibers and can be pre-buried in the optical cable trench to serve as a communication link for conducting optical signals corresponding to optical communication services. Often times, hard debris (e.g., stones) often occurs in the cable trench. These hard contaminants can cause abrasion to the fiber optic cable, resulting in damage to the optical fibers in the cable and failure to conduct optical signals. Alternatively, the optical cables in the cable trench may often be twisted off due to some undesired twisting, which may damage the optical fibers in the optical cables and may not conduct the optical signals.

For the phenomenon that the optical fiber is damaged and cannot transmit the optical signal, a spare optical fiber can be arranged to ensure the normal operation of the optical communication service. For example, when an optical fiber in a certain optical cable is damaged and cannot conduct an optical signal, the spare optical fiber can be started to conduct the optical signal, thereby ensuring normal operation of the optical communication service. To distinguish the spare fiber, the fiber that conducts the optical signal corresponding to the optical communication service when the spare fiber is not active may be referred to as the active fiber.

When the standby optical fiber is installed, if the active optical fiber and the standby optical fiber are installed in the same optical cable, or the optical cable in which the active optical fiber is installed and the optical cable in which the standby optical fiber is installed are located in the same cable trench, the active optical fiber and the standby optical fiber may lose the function of transmitting optical signals at the same time. For example, both active and standby fibers may be twisted off, at which point optical traffic may not proceed properly.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

For the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, the terms "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the terms "first", "second", and the like are not limited in number or execution order.

The optical fiber may be a fiber made of glass or plastic, referred to as an optical fiber for short. The optical cable can be formed by a plurality of optical fibers and can be pre-buried in the optical cable trench to serve as a communication link for conducting optical signals corresponding to optical communication services. The optical communication service is as follows: and carrying out communication service by taking the optical signal as a carrier.

Exemplarily, fig. 1 is a schematic diagram of embedding an optical cable in a cable trench. As shown in fig. 1, optical cables may be embedded in the optical cable trench, and the optical cables may include a plurality of optical fibers. Optionally, the optical cable may further include a reinforcing steel wire, a filler, a waterproof layer, a buffer layer, an insulated metal wire, and other members, and the embodiment of the present application does not limit the specific composition of the optical cable. In addition, although fig. 1 exemplarily shows one optical cable, in a practical scenario, a plurality of optical cables may be pre-buried in the optical cable trench, which is not limited herein.

Often times, hard debris (e.g., stones) often occurs in the cable trench. These hard contaminants can cause abrasion to the fiber optic cable, resulting in damage to the optical fibers in the cable and failure to conduct optical signals. Alternatively, the optical cables in the cable trench may often be twisted off due to some undesired twisting, which may damage the optical fibers in the optical cables and may not conduct the optical signals.

For example, fig. 2 is a schematic view of a scenario in which poor twisting of the optical cable occurs. As shown in fig. 2, a plurality of optical cables may be buried in the cable trench, the optical cables may be twisted together and may be undesirably twisted, the optical cables may be twisted by the undesirable twisting, the optical fibers in the optical cables may be damaged (twisted), and the optical fibers may not conduct optical signals.

In view of the above-mentioned phenomenon that the optical fiber is damaged and cannot transmit the optical signal, a spare optical fiber may be usually provided to ensure the normal operation of the optical communication service. For example, when an optical fiber in a certain optical cable is damaged and cannot conduct an optical signal, the spare optical fiber can be started to conduct the optical signal, thereby ensuring normal operation of the optical communication service. To distinguish the spare fiber, the fiber that conducts the optical signal corresponding to the optical communication service when the spare fiber is not active may be referred to as the active fiber.

When the standby optical fiber is installed, if the active optical fiber and the standby optical fiber are installed in the same optical cable, or the optical cable in which the active optical fiber is installed and the optical cable in which the standby optical fiber is installed are located in the same optical cable trench, the active optical fiber and the standby optical fiber may lose the function of transmitting optical signals at the same time. For example, both active and standby fibers may be twisted off, at which point optical traffic may not proceed properly.

The active optical fiber and the standby optical fiber are arranged in the same optical cable and can be called as the same cable of the active optical fiber and the standby optical fiber; the cables in which the active optical fiber and the standby optical fiber are located are in the same cable trench and can be called as the active optical fiber and the standby optical fiber.

In this background, embodiments of the present application provide an optical fiber monitoring method, by which a co-cabling situation of any two optical fibers can be identified, so as to avoid setting the co-cabled optical fiber as a spare optical fiber.

Fig. 3 is a schematic diagram of an application scenario provided in an embodiment of the present application.

As shown in fig. 3, an application scenario of the embodiment of the present application may include: an optical fiber 31 to be tested, an Optical Time Domain Reflectometer (OTDR) testing device 32, and an optical fiber monitoring device 33. The optical fiber 31 to be tested is connected with the OTDR test equipment 32, and the OTDR test equipment 32 is connected with the optical fiber monitoring equipment 33.

The optical fiber to be tested 31 may include at least two optical fibers.

The OTDR test equipment 32 can collect OTDR test curve data of each optical fiber 31 to be tested.

The fiber monitoring device 33 may be a server cluster composed of a plurality of servers, or a single server, or a computer, or a processor or a processing chip in a server or a computer, etc. The embodiment of the present application does not limit the specific device form of the optical fiber monitoring device 33.

The optical fiber monitoring method provided by the embodiment of the present application can be applied to the optical fiber monitoring device 33 shown in fig. 3. The optical fiber monitoring device 33 can identify whether any two optical fibers in the optical fiber 31 to be detected are in the same cable through the optical fiber monitoring method provided in the embodiment of the present application, so as to avoid setting the optical fibers in the same cable as spare optical fibers.

Taking the example that the optical fiber 31 to be detected includes a first optical fiber and a second optical fiber (the first optical fiber is different from the second optical fiber), fig. 4 is a schematic flowchart of the optical fiber monitoring method provided in the embodiment of the present application. As shown in fig. 4, the method may include S401 to S407.

S401, acquiring first OTDR test curve data of a first optical fiber and second OTDR test curve data of a second optical fiber, wherein the first OTDR test curve data of the first optical fiber and the second OTDR test curve data of the second optical fiber are acquired by OTDR test equipment.

S402, obtaining first optical fiber event data of the first optical fiber according to the first OTDR test curve data.

And S403, obtaining second optical fiber event data of the second optical fiber according to the second OTDR test curve data.

It is understood that S402 may be performed after S403, or S402 may be performed before S403, or S402 and S403 may be performed simultaneously. The execution order of S402 and S403 is not limited in the embodiment of the present application.

It can be understood that the above S401 to S403 also obtain first fiber event data of the first fiber and second fiber event data of the second fiber.

The first optical fiber event data and the second optical fiber event data may respectively include an optical fiber type, an optical fiber initiation event, an optical fiber far-end event, an optical fiber loss coefficient, an optical fiber fusion point, optical fiber bending information, optical fiber power-off information, optical fiber connector information, optical fiber vibration information, and the like.

In a possible design, the obtaining first fiber event data of the first optical fiber according to the first OTDR test curve data may include: and performing data fitting on the first OTDR test curve data by using a data fitting algorithm, and performing event extraction on the first OTDR test curve data after the data fitting by using an event extraction algorithm to obtain first optical fiber event data.

Similarly, the obtaining second fiber event data of the second optical fiber according to the second OTDR test curve data may include: and performing data fitting on the second OTDR test curve data by using a data fitting algorithm, and performing event extraction on the second OTDR test curve data after the data fitting by using an event extraction algorithm to obtain second optical fiber event data.

The data fitting algorithm and the event extraction algorithm are relatively mature known technologies, and the specific types of the data fitting algorithm and the event extraction algorithm are not limited in the embodiment of the application.

It should be noted that the OTDR test device 32 may be a device independent from the fiber monitoring device 33; alternatively, the OTDR test device 32 may also be integrated in the fiber monitoring device 33, as a whole with the fiber monitoring device 33. The embodiment of the present application does not limit the specific implementation manner of the OTDR test device 32.

S404, calculating the similarity between the first optical fiber event data and the second optical fiber event data to obtain a first similarity.

For example, the optical fiber monitoring device 33 may calculate the event similarity between the optical fiber event data of the first optical fiber and the optical fiber event data of the second optical fiber by using a preset similarity algorithm, so as to obtain the first similarity.

The similarity algorithm may be an euclidean distance algorithm, a cosine similarity algorithm, or the like.

In some possible embodiments, calculating an event similarity between the fiber event data of the first optical fiber and the fiber event data of the second optical fiber to obtain a first similarity includes: respectively extracting the characteristic information of the optical fiber event data of the first optical fiber and the characteristic information of the optical fiber event data of the second optical fiber, and according to the characteristic information of the optical fiber event data of the first optical fiber and the characteristic information of the optical fiber event data of the second optical fiber; and calculating the event similarity between the optical fiber event data of the first optical fiber and the optical fiber event data of the second optical fiber to obtain a first similarity.

S405, judging whether the first similarity is larger than a preset same-cable judgment threshold value.

If yes, go to step S406; if not (i.e., the first similarity is less than or equal to the preset on-cable decision threshold), S407 is executed.

In some possible embodiments, the in-line decision threshold is related to a number of fibers in a region where the first fiber and the second fiber are located. For example, the greater the number of fibers in the region where the first fiber and the second fiber are located, the greater the in-line decision threshold.

In a possible implementation manner, the on-line decision threshold may be determined by a manager according to the number of optical fibers in the area where the first optical fiber and the second optical fiber are located and the personal experience, and input into the optical fiber monitoring device 33.

Exemplarily, assuming that the area where the optical fiber 1 and the optical fiber 2 are located is a city a and the number of optical fibers arranged in the city a is large, the manager determines that the co-cable judgment threshold of the optical fiber of the city a is 70% according to the large number of optical fibers arranged in the city a and the large probability that the event data of the optical fiber is similar under the large number of optical fibers, and inputs 70% of the co-cable judgment threshold into the optical fiber monitoring device 33; or, assuming that the area where the optical fibers 1 and 2 are located is a town B and the number of optical fibers set in the town B is small, the manager determines that the on-line judgment threshold of the optical fibers of the town B is 60% according to the fact that the probability that the event data of the optical fibers are similar is small when the number of the optical fibers set in the town B is small and the number of the optical fibers is small, and inputs 60% of the on-line judgment threshold into the optical fiber monitoring device 33.

In another possible implementation manner, the on-line decision threshold may be determined by the optical fiber monitoring device 33 according to the number of optical fibers in the areas where the first optical fiber and the second optical fiber are located and a preset algorithm. For example, the fiber monitoring device 33 may determine the on-line decision threshold before performing S405.

Exemplarily, fig. 5 is a schematic flowchart of a process for determining an in-line decision threshold according to an embodiment of the present application. As shown in fig. 5, the process of determining the on-line decision threshold may include S501 and S502.

S501, acquiring the number of optical fibers in the area where the first optical fiber and the second optical fiber are located.

S502, determining a co-cable judgment threshold according to the number of optical fibers in the area where the first optical fiber and the second optical fiber are located.

Alternatively, the number of optical fibers and the on-line decision threshold may have a corresponding relationship. The step of determining the in-line decision threshold according to the number of the optical fibers in the region where the first optical fiber and the second optical fiber are located may include: the optical fiber monitoring device 33 determines the co-cable decision threshold according to the number of optical fibers in the areas where the first optical fiber and the second optical fiber are located and the corresponding relationship between the number of optical fibers and the co-cable decision threshold.

Exemplarily, assuming that the co-cabling judgment threshold corresponding to 10000 optical fibers is 70%, the area where the optical fibers 1 and 2 are located is the city a, and 10000 optical fibers are set in the city a, the optical fiber monitoring device 33 may determine that the co-cabling judgment threshold of the optical fibers of the city a is 70% according to that 10000 optical fibers are set in the city a and the co-cabling judgment threshold corresponding to 10000 optical fibers is 70%; or, assuming that the co-cable judgment threshold corresponding to 5000 optical fibers is 60%, the area where the optical fibers 1 and 2 are located is the town B, and 5000 optical fibers are set in the town B, the optical fiber monitoring device 33 may determine that the co-cable judgment threshold of the optical fibers in the town B is 60% according to the fact that 5000 optical fibers are set in the town B and the co-cable judgment threshold corresponding to 5000 optical fibers is 60%.

It should be noted that, the corresponding relationship between the number of optical fibers and the co-cable judgment threshold value may be preset in the optical fiber monitoring device 33, and in the corresponding relationship between the number of optical fibers and the co-cable judgment threshold value, the number of optical fibers and the co-cable judgment threshold value are in a positive correlation relationship, that is, the larger the number of optical fibers is, the larger the co-cable judgment threshold value is. In addition, in the corresponding relation between the number of the optical fibers and the co-cable judgment threshold value, the number of the optical fibers and the specific size of the co-cable judgment threshold value are not limited.

Optionally, the on-cable decision threshold may include a first on-cable decision threshold and a second on-cable decision threshold, where the first on-cable decision threshold is greater than the second on-cable decision threshold, and the step of determining the on-cable decision threshold according to the number of optical fibers in the areas where the first optical fiber and the second optical fiber are located may include: judging whether the number of the optical fibers in the area where the first optical fiber and the second optical fiber are located is larger than a preset first threshold value or not; if so, determining that the co-cable judgment threshold is a first co-cable judgment threshold; and if not, determining that the co-cable judgment threshold is the second co-cable judgment threshold.

Exemplarily, taking an area where the optical fibers 1 and 2 are located as a city a, and setting 10000 optical fibers in the city a as an example, assuming that the first threshold is 8000 optical fibers, the first in-line cable decision threshold is 70%, and the second in-line cable decision threshold is 60%, the optical fiber monitoring device 33 determines that the in-line cable decision threshold of the city a is 70% by determining that the 10000 optical fibers in the city a are greater than the preset first threshold 8000 optical fibers according to the setting of 10000 optical fibers in the city a and the first threshold is 8000 optical fibers; or, taking the area where the optical fiber 1 and the optical fiber 2 are located as a town B, and 5000 optical fibers are set in the town B as an example, assuming that the first threshold is 8000 optical fibers, the first on-cable judgment threshold is 70%, and the second on-cable judgment threshold is 60%, the optical fiber monitoring device 33 judges that the 5000 optical fibers in the town B are smaller than the preset first threshold of 8000 optical fibers, and determines that the on-cable judgment threshold of the town B is 60% according to the fact that the first threshold is set in the town B, and the first threshold is 8000 optical fibers.

S406, determining that the first optical fiber and the second optical fiber are in the same cable.

Illustratively, also taking the above-mentioned co-cabling decision threshold of the optical fiber of city a as 70% as an example, assuming that the optical fiber 1 and the optical fiber 2 are buried in city a, and the event similarity between the optical fiber event data of the optical fiber 1 and the optical fiber event data of the optical fiber 2 is 80%, determining that the event similarity between the optical fiber event data of the optical fiber 1 and the optical fiber event data of the optical fiber 2 is greater than the co-cabling decision threshold of 70%, and determining that the optical fiber 1 and the optical fiber 2 are co-cabled. It will be appreciated that the same cable must be in the same trench, so when the event similarity between the fiber event data for fiber 1 and the fiber event data for fiber 2 is greater than the same cable decision threshold, it can be determined that fiber 1 and fiber 2 are in the same trench and are in the same cable.

And S407, determining that the first optical fiber and the second optical fiber are different cables.

Optionally, when the first similarity is smaller than or equal to the on-cable decision threshold (that is, when it is determined that the first optical fiber and the second optical fiber are not in the same cable), it may be determined that the second optical fiber is used as a spare optical fiber for the first optical fiber, or it may be determined that the first optical fiber is used as a spare optical fiber for the second optical fiber.

The optical fiber monitoring method provided by the embodiment of the application can firstly acquire first optical fiber event data of a first optical fiber and second optical fiber event data of a second optical fiber, calculate the similarity of the first optical fiber event data and the second optical fiber event data to acquire a first similarity, and determine that the optical fibers are in the same ditch and the same cable when the first similarity is greater than a preset same cable judgment threshold value, so that two optical fibers in the same ditch and the same cable can be prevented from being provided with spare optical fibers, and the normal operation of optical communication services is ensured.

In other embodiments, when the method determines that the first optical fiber and the second optical fiber are not the same cable, it may further determine whether the first optical fiber and the second optical fiber are the same groove. Fig. 6 is a schematic flow chart of another optical fiber monitoring method according to an embodiment of the present disclosure. As shown in fig. 6, after S407 or when it is determined in S405 that the first similarity is smaller than or equal to the preset on-cable decision threshold (for example, in fig. 6, when the determination result of S405 is no, S601 is directly executed), the method may further include S601 to S603.

S601, judging whether the first similarity is larger than a preset same-ditch judgment threshold value.

If yes, go to S602; if not, go to S603.

Wherein, the same-channel decision threshold value can be smaller than the same-cable decision threshold value.

In some possible embodiments, the in-groove decision threshold is related to a number of fibers in a region where the first fiber and the second fiber are located. For example, the larger the number of optical fibers in the region where the first optical fiber and the second optical fiber are located, the larger the same-trench decision threshold value.

In a possible implementation manner, the same-trench decision threshold may be determined by a manager according to the number of optical fibers in the region where the first optical fiber and the second optical fiber are located and the personal experience, and input into the optical fiber monitoring device 33.

Exemplarily, assuming that the area where the optical fiber 1 and the optical fiber 2 are located is a city a and the number of optical fibers arranged in the city a is large, the manager determines that the co-channel decision threshold of the optical fiber of the city a is 60% according to the large number of optical fibers arranged in the city a and the large probability that the event data of the optical fiber is similar under the large number of optical fibers, and inputs 60% of the co-channel decision threshold into the optical fiber monitoring device 33; or, assuming that the area where the optical fiber 1 and the optical fiber 2 are located is a town B and the number of optical fibers set in the town B is small, the manager determines that the co-channel decision threshold of the optical fiber of the town B is 50% according to the small number of optical fibers set in the town B and the small probability that the event data of the optical fiber are similar when the number of optical fibers is small, and inputs 50% of the co-channel decision threshold into the optical fiber monitoring device 33.

In another possible implementation manner, the same-trench decision threshold may be determined by the optical fiber monitoring device 33 according to the number of optical fibers in the region where the first optical fiber and the second optical fiber are located and a preset algorithm.

It should be noted that, the corresponding relationship between the number of optical fibers and the co-channel decision threshold may be preset in the optical fiber monitoring device 33, and in the corresponding relationship between the number of optical fibers and the co-channel decision threshold, the number of optical fibers and the co-channel decision threshold are in a positive correlation relationship, that is, the larger the number of optical fibers is, the larger the co-channel decision threshold is. In addition, in the corresponding relation between the number of the optical fibers and the same-groove judgment threshold value, the number of the optical fibers and the specific size of the same-groove judgment threshold value are not limited.

The second threshold may be different from the first threshold, or the second threshold is the same as the first threshold, and the size relationship between the first threshold and the second threshold is not limited in this embodiment of the application.
