Description

Technical Field

[0001] This application relates to the field of fiber optic routing technology, and in particular to a method, apparatus, and system for finding fiber optic routes. Background Technology

[0002] Optical fiber is the primary signal transmission medium in modern optical communication systems. It connects optical communication equipment deployed in communication rooms, base stations, and other nodes across various industries, forming the most important infrastructure network for current data communication. Optical cable is a communication line component that uses one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. It typically consists of optical fibers, a protective sheath, an outer sheath, and metal reinforcements. In cities, optical cable lines are mainly laid underground as information pipelines and overhead lines, with underground pipelines being the primary method in urban areas. In recent years, most Chinese cities have implemented underground fiber optic cable network projects, resulting in an increasing amount of underground fiber optic cable. Besides the most common mobile operator communication optical cables, power grids and oil and gas pipelines also have their own communication optical cable networks. These dedicated optical cable networks are typically underground information pipelines in cities and directly buried underground in rural areas.

[0003] Fiber optic routing refers to the direction and location information of the optical cable line in the actual environment. New optical cables are typically laid in 1-2km sections coiled together, either through ductwork or directly buried according to the designed route, with each section spliced ​​together. In reality, optical cable lines often have numerous coils and slack at splice points. The length of the fiber optic line from its starting point does not necessarily correspond to its position on a map. Furthermore, during construction, the actual route often deviates from the design drawings due to factors such as blocked ducts and complex environments. Therefore, without accurate fiber optic routing information, it is difficult to quickly and accurately locate the actual fault location for line repair in various fiber optic maintenance scenarios, and it is also difficult to accurately and effectively monitor and manage a large number of optical communication lines. Currently, the methods commonly used for locating and detecting fiber optic routes are:

[0004] 1. First, with the help of an optical time domain reflectometer (OTDR), the fiber length and fiber sheath length (i.e., the total fiber length from the event point to the fiber start point) data can be detected at one end of the optical fiber in the equipment room or optical cross-connection.

[0005] 2. At the site along the route specified in the design documents, select facilities such as fiber optic cable manholes along the route. Bend any fiber optic cable to cause fiber loss, and simultaneously check if the OTDR meter displays real-time loss data. This helps determine if the cable is the one connected to the OTDR in the equipment room and its fiber sheath length. If no loss is detected, the wrong cable is considered and it should be replaced and tested again. If no loss is detected in any cable within the manhole, the wrong manhole is considered. If no loss is detected in any cable within nearby manholes, the route is considered inconsistent with the design documents, and further testing should be conducted in another environment. Using an OTDR and inducing loss by bending the fiber optic cable can, to some extent, locate the fiber optic route. However, this operation often causes irreversible damage to the cable, accelerating cable aging and potentially damaging numerous non-target cables on-site. It is a route-finding method that is ultimately counterproductive.

[0006] 3. In addition to the methods mentioned above, a fiber optic cable surveying instrument can be used. This instrument is connected to one end of the optical fiber, and points that may be the target cable are located on-site. The individual cable is then tapped and vibrated. If the correct cable is found, the equipment end will see a signal and hear a tapping sound. This method can locate the target cable without damaging it, but it cannot measure the fiber sheath length at the tapping point, nor can it measure the length of cables that cannot be directly tapped. Therefore, it does not effectively solve the problem of accurate route finding.

[0007] Therefore, there is a need for a technical solution to address or at least mitigate the aforementioned shortcomings of existing technologies. Summary of the Invention

[0008] The purpose of this invention is to provide a method for finding fiber optic routes to at least solve one of the aforementioned technical problems.

[0009] This invention provides the following solution:

[0010] According to one aspect of the present invention, a method for finding an optical fiber route is provided, the method comprising:

[0012] The vibration signals of the entire optical fiber to be searched, collected by the intelligent operation and maintenance instrument at each preset test location during the occurrence of a special event, are obtained respectively.

[0013] The entire routing data of the fiber to be searched is determined based on the vibration signals collected by the intelligent operation and maintenance instrument along the entire fiber during the occurrence of a special event at each preset test location.

[0014] Optionally, the step of determining the full-line routing data of the optical fiber to be searched based on the vibration signals of the entire optical fiber collected by the intelligent operation and maintenance instrument during the generation of a special event at each preset test location includes:

[0015] During each specific event, the full-line routing data of the fiber optic cable to be located is determined by performing the following processing:

[0016] Obtain theoretical vibration signals of special events based on special events;

[0017] The theoretical vibration signal is compared with the vibration signal of the entire optical fiber to be searched under the special event. It is determined whether the vibration signal of a preset test position is successfully matched with the theoretical vibration signal of the special event. If so, the preset test position that is successfully matched is determined as the routing point of the optical fiber to be searched. The obtained routing points constitute the entire line routing data.

[0018] Optionally, the special event includes at least one event material;

[0022] Optionally, the event footage includes footage of vehicles driving over the optical cable, construction footage over the optical cable, and footage of water flow ripples.

[0023] Optionally, the special events are acquired through drone photography and / or through human intervention.

[0024] This application also provides an apparatus for locating fiber optic routes, the apparatus comprising:

[0025] A preset test location acquisition module is used to acquire the preset test location of the optical fiber to be searched.

[0026] The fiber optic cable vibration signal acquisition module is used to acquire the vibration signal of the entire fiber optic cable to be searched collected by the intelligent operation and maintenance instrument at each preset test location during the occurrence of a special event.

[0027] The full route data generation module is used to determine the full route data of the optical fiber to be searched based on the vibration signal of the entire optical fiber collected by the intelligent operation and maintenance instrument during the occurrence of a special event at each preset test location.

[0028] This application also provides a system for locating fiber optic routes, the system comprising:

[0029] Intelligent maintenance instrument, which is used to collect vibration signals of the entire optical fiber to be located;

[0033] The fiber optic route finding method proposed in this application has the following advantages over current fiber optic route finding methods: 1. This method eliminates the need to bend the optical cable on-site, avoiding damage. 2. Without directly vibrating the optical cable on-site, it can quickly find the route for most sections of the line, obtaining a general direction and providing accurate range guidance for supplementary testing of other points, greatly improving the efficiency and accuracy of fiber optic route finding. 3. Traditional route finding requires one person in the equipment room to operate and check equipment such as the OTDR, and several maintenance personnel to bend or tap the optical cable on-site; this method only requires one person to operate a drone, saving a significant amount of manpower.

[0040] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Figure 1 This is a flowchart illustrating a method for finding fiber optic routes according to an embodiment of this application.

[0042] like Figure 1 The methods for finding fiber optic routes shown include:

[0043] Step 1: Obtain the preset test location of the optical fiber to be searched;

[0044] Step 2: Obtain the vibration signal of the entire optical fiber to be searched collected by the intelligent operation and maintenance instrument at each preset test location during the occurrence of a special event;

[0045] Step 3: Determine the full route data of the fiber to be searched based on the vibration signal of the entire fiber collected by the intelligent operation and maintenance instrument during the occurrence of a special event at each preset test location.

[0046] In this embodiment, determining the full-line routing data of the optical fiber to be searched based on the vibration signals collected by the intelligent operation and maintenance instrument during the occurrence of a special event at each preset test location includes:

[0047] During each specific event, the full-line routing data of the fiber optic cable to be located is determined by performing the following processing:

[0048] Obtain theoretical vibration signals of special events based on special events;

[0049] The theoretical vibration signal is compared with the vibration signal of the entire optical fiber to be searched under the special event. It is determined whether the vibration signal of a preset test position is successfully matched with the theoretical vibration signal of the special event. If so, the preset test position that is successfully matched is determined as the routing point of the optical fiber to be searched. The obtained routing points constitute the entire line routing data.

[0050] In this embodiment, the special event includes at least one event material;

[0051] The method of obtaining the theoretical vibration signal of a special event based on a special event includes:

[0052] Obtain a special event material library, which includes at least one preset event material and vibration information for each event material;

[0053] The vibration information corresponding to the preset event material that is the same as the event material is obtained as the theoretical vibration signal of the special event.

[0054] In this embodiment, the event materials include materials showing vehicles driving over the optical cable, construction work over the optical cable, and water flow ripples.

[0055] In this embodiment, the special event is acquired through drone photography and / or through human intervention.

[0056] The following examples further illustrate this application in detail. It is understood that these examples do not constitute any limitation on this application.

[0057] Step 1: Obtain the preset test location of the optical fiber to be searched. In this embodiment, the preset test location can be set manually. For example, the location may be selected as the preset test location if it is a highway, railway, or mechanical construction event that may cross or accompany the optical cable line, or if it crosses a lake, pond, or overhead section, or if it may cause vibration along the optical cable line.

[0058] The intelligent operation and maintenance device (O&M) collects vibration signals along the entire optical fiber to be located at each preset test location during the occurrence of a special event. Specifically, the O&M is connected to a spare optical fiber core of the optical cable line under test in the ODF rack of the communication equipment room or an outdoor optical distribution box. Then, the O&M is activated to collect vibration signals along the entire line, and the data is saved and synchronized to the platform server in real time. Throughout the entire optical fiber routing search cycle, the O&M continuously collects vibration signals along the entire line.

[0059] Based on the vibration signals of the entire optical fiber to be searched collected by the intelligent operation and maintenance instrument at each preset test location during the occurrence of a special event, the entire route data of the optical fiber to be searched is determined. Specifically, during each special event, the entire route data of the optical fiber to be searched is determined by performing the following processing:

[0060] Obtain theoretical vibration signals of special events based on special events;

[0061] The theoretical vibration signal is compared with the vibration signal of the entire optical fiber to be searched under the special event. It is determined whether the vibration signal of a preset test position is successfully matched with the theoretical vibration signal of the special event. If so, the preset test position that is successfully matched is determined as the routing point of the optical fiber to be searched. The obtained routing points constitute the entire line routing data.

[0062] Compared with current methods for finding routes in optical fiber communication, this application has the following advantages:

[0063] 1. This method eliminates the need to bend the optical cable on-site, avoiding damage. 2. Without directly vibrating the optical cable on-site, it can quickly locate the route for most sections of the line, providing a general direction and accurate range guidance for supplementary testing of other points, greatly improving the efficiency and accuracy of fiber optic route finding. 3. Traditional route finding requires one person in the equipment room to operate and check equipment such as the OTDR, and several maintenance personnel to bend or tap the optical cable on-site; this method only requires one person to operate the drone, saving a significant amount of manpower. 4. Utilizing mature vehicle and other moving object recognition algorithms, the platform server can mark moving vehicles and their trajectories, construction machinery, etc., in real time when receiving on-site images from the drone. Combined with vibration signals synchronously transmitted by the intelligent maintenance instrument, real-time line marking confirmation is achieved. Preliminary line routing data can be generated after the drone completes one patrol; the saved on-site images and vibration signals can be used as the basis for subsequent automatic or manual calibration data. 5. Due to significant deviations in current route information, accurate reference points are lacking when searching manually. This results in a substantial time commitment for initial point finding. For a 30km route with 100 measurement points, route finding would require approximately 3 people (1 in the server room and 2 on-site) spending 6-9 working days (each person on-site measuring 6-10 points per day), totaling 18-27 person-days. The method of this invention, using a drone for rapid navigation and data generation, requires only 1 person per day. Further on-site testing and verification of additional points can then be completed by 1 person in 1-2 days, bringing the total cost to 2-3 person-days. This significantly reduces the time required and lowers the cost of route finding.

[0064] In this embodiment, by deploying drones, a large number of personnel can be efficiently replaced for on-site investigation and testing. Using drones to obtain information about special events has the following advantages:

[0065] (1) Drones can monitor from the air, thus having a bird's-eye view and enabling relatively complete event capture.

[0066] (2) Drones fly faster than humans and can achieve high-speed patrols.

[0067] (3) Drones can transmit image information and other information in real time via the network, which is convenient and fast.

[0068] See Figures 3 to 6 The following is a specific example to further illustrate this application.

[0069] See Figure 3 First, connect the intelligent operation and maintenance device to a spare optical fiber core of the optical cable line under test in the ODF rack of the communication equipment room or an outdoor optical distribution box. Next, turn on the intelligent operation and maintenance device to collect vibration signals along the entire line and save and synchronize the data to the platform server in real time.

[0070] In this embodiment, the special events of this application are first obtained through a drone. Specifically, the drone sets its flight path according to the general direction of the optical cable line and begins to cruise.

[0071] When a drone encounters situations during flight that might cross or accompany the fiber optic cable line, such as highways, railways, or construction sites, or when it crosses lakes, ponds, or overhead sections that could cause vibrations along the cable, special events are artificially generated. At these locations, the drone hovers and records the environment or event, noting local GPS coordinates and time information, and transmits the data back to the platform server. The hovering recording time at each location is approximately 1-10 minutes, capturing real-time vibration events along the cable line, such as vehicles passing through the area on a highway or construction machinery operating nearby. The drone continues to search and record feature point data along its trajectory. After completing the first full-line search, the platform compares the information of each feature point with the corresponding time vibration signals transmitted by the intelligent maintenance instrument, matching the line vibration signals with the on-site feature locations. It also checks for situations where the maintenance instrument has collected vibration signals but no matching environment is found on-site. If such situations exist, the relevant fiber length and approximate location on the line are marked, and the drone performs a secondary confirmation of these locations, recording on-site images, GPS coordinates, and time information, and transmitting the data back.

[0072] After completing the above-mentioned secondary confirmation, a fast route lookup form is generated using the fiber optic route lookup method of this application, the line routing data is updated, and an electronic map of the line is drawn.

[0073] When no special events occur at certain preset test locations, on-site personnel can go to locations along the line that have not yet been measured, such as some manholes, and use an APP to remotely operate the intelligent operation and maintenance instrument to collect and view vibration signals. The optical fiber length is obtained by artificially vibrating the optical cable. At the same time, the GPS coordinates of the current location are recorded on the same APP and can be directly transmitted back to the platform server to update and complete the line routing data, and then draw an accurate and complete electronic map of the line.

[0074] Specifically, refer to the appendix Figures 4 to 6 The intelligent operation and maintenance instrument connects to one end of a single optical fiber in the optical cable line leading from the ODF rack in the computer room or the outdoor optical distribution box, and collects and uploads vibration signals of the entire line in real time.

[0075] See signal curve pattern Figure 5 The horizontal axis represents the fiber optic cable length, with the connection end of the maintenance instrument as the starting zero point, and the vertical axis represents the vibration intensity at any fiber optic location.

[0076] The drone cruises along the fiber optic line from the origin of the computer room, for example, in Figure 4Point A (preset test location, location name, such as point A where the fiber optic cable crosses the road) is where the cable crosses the road. When a vehicle drives over the cable, the ground vibration is transmitted to the cable, and at this time... Figure 5 A strong vibration signal appeared synchronously at position ① of the vibration curve, where the fiber optic cable length is denoted as L. A .

[0077] The drone hovers at point A for 1-10 minutes, recording the coordinate data as GPS data. A Several vehicles were captured on video as they passed point A. The time points at which the vehicles passed and the vibration curve L were recorded. A The vibration signal at the location should exhibit a synchronous fluctuation pattern, which the platform can then confirm and generate AL data from the uploaded data. A GPS A The correspondence.

[0078] Similarly, drones to Figure 4 Data from the highway crossing points B, C, and G were recorded and uploaded, and compared with the vibration signals collected by the maintenance instrument to establish a correspondence between these points.

[0079] exist Figure 4 At point D on the line, the drone detects a construction site near the line and captures real-time video of the mechanical construction operations. The platform server compares the synchronization characteristics of the vibration signals with... Figure 5 The curve at position ④ matches, and the fiber optic cable length at that point is denoted as L. D .

[0080] Figure 4 In the section between E1 and E2, the actual route runs alongside the highway. Vibrations from vehicles along the route are transmitted until they are collected by the intelligent maintenance instrument on the fiber optic cable, and the signal location continues to move. When the drone observes this section of the route, it records images of vehicles driving. Figure 5 Between positions ⑤ and ⑥ of the vibration curve, multiple vibration signals can be seen moving continuously from ⑤ to ⑥ or in the opposite direction (from ⑥ to ⑤). The signals disappear outside this section (because the optical cable line is separated from the highway and no longer runs alongside it, the optical cable no longer receives vibration signals from the vehicle). Based on this, the platform server confirms the correspondence and records the fiber optic cable length at position ⑤ as LE1 and the fiber optic cable length at position ⑥ as LE2.

[0081] Figure 4 The drone will discover a pond between F1 and F2, at which point... Figure 5The vibration signal between positions ⑦ and ⑧ in the vibration curve is a continuous vibration signal in space. The most significant characteristic of this signal is that it is also continuous in time, unlike the intermittent vibration signals caused by vehicles crossing optical cables or construction along the line. The actual reason is that when the optical cable passes through the pond from the bottom, the fluctuation of the water flow will continuously transmit vibration signals to the optical cable. At this time, the platform server confirms the correspondence and records the fiber optic cable length at position ⑦ as LF1 and the fiber optic cable length at position ⑧ as LF2.

[0082] After the drone completes its initial patrol and search of the line characteristics, it checks the vibration curve to see if there are any more unconfirmed strong vibration signal points at the fixed fiber optic cable length location. Then, the drone is sent to the estimated location on-site for a second search (in this example,...). Figure 5 (The corresponding on-site locations of all nine vibration intensity points on the curve have been found.) Upon completion, the platform server generates the following routing data form:

[0083] Table 1. Quick Lookup Form for Routing Data Generated in Phase 1

[0084]

[0085] Table 1 lists the data items for each location, including serial number, location name, coordinates, fiber optic cable length, and environmental description. The data for each location is sorted in ascending order of fiber optic cable length. The platform server uses this table to generate the first phase of the electronic route map.

[0086] In the second phase, guided by the completed data and route map, one staff member manually applies vibration interference to the target optical cable at pre-set test locations along the route that have not yet been measured, such as manholes at route bends. This allows the vibration intensity point to be located on the vibration curve simultaneously displayed on the maintenance instrument's app, and the fiber optic cable's length and GPS coordinates of the test location are recorded. In this example, that is... Figure 4 The fiber optic cable lengths obtained from the wells at positions a, b, and c are L respectively. a L b L c GPS coordinates are respectively GPS a GPS b GPS c The routing data for these three locations was inserted into the original form by the platform server in order of fiber optic cable length. The updated data table will then look like this:

[0087] Table 2. Quick Lookup Form for Routing Data Generated in Phase Two

[0088]

[0089] In Table 2, after inserting data from three new key location wells along the route, relatively complete and accurate routing data has been formed. The platform server can then use this data to create an electronic map of the route, the format of which will be similar to... Figure 4 The situation is basically the same as that in China.

[0090] In certain pre-designed test locations, such as urban environments with numerous and complex fiber optic cable routes, this invention can accurately and quickly determine the route of the cable by precisely marking the movement of the vibration source target and synchronously detecting the characteristics of the vibration signal in real time. Now, let's take... Figure 6 The crossroads environment shown illustrates this determination method:

[0091] 1. Figure 6 At the intersection shown, three optical distribution boxes, A, B, and C, are located nearby. The following optical cable lines run along these routes:

[0092] 1) There are lines 1 and 2 between optical cross-connect A and optical cross-connect B;

[0093] 2) There are lines 3 and 4 between optical cross-connector B and optical cross-connector C.

[0094] In typical optical communication line resource management systems, line routes only record partial node information, such as equipment rooms, optical distribution boxes, and a few optical cable wells. For example, the route of line 2 mentioned above may be drawn as line 1, directly connecting optical distribution boxes A and B. The actual route information of line 2 is lost. When it is actually necessary to repair the line fault or find the route, line 2 cannot be found in the two wells of the AB optical distribution straight line to complete the work.

[0095] 2. Figure 4 The diagram shows four vehicles coming from different directions, preparing to cross the intersection. They are labeled as vehicles A, B, C, and D.

[0096] 3. When determining the route direction at this intersection, the intelligent operation and maintenance instrument is located in the communication room or a certain optical cross-connector. Figure 4 Vibration data is collected in real time on one of several routes. A drone hovers above the intersection to capture environmental video and specifically marks vehicle movement dynamics and time. When the main traffic light at the intersection is red and vehicles are basically at a standstill, the vibration signal processing for that area is in a silent state. Then, based on the relationship between vehicle movement and vibration signals, the route direction is determined, as illustrated by the following example:

[0097] 1) When the intelligent operation and maintenance instrument is connected to the fiber optic cable of line 1, only observe vehicle C. When it goes straight or turns right across the intersection, there is no obvious vibration signal. When it turns left and at the same moment it completes the turn and enters the road on its left, the intelligent operation and maintenance instrument will collect a vibration signal. Then it can be determined that the route is the straight line of optical intersection AB, and the fiber optic cable length at the crossing point is the fiber optic cable length where this vibration signal is located.

[0098] 2) When the intelligent maintenance device is connected to the fiber optic cable of Line 2, there will be no signal when vehicle C turns left. At the same time when it turns right into the lower right road, the maintenance device will collect a signal. When it goes straight, after passing the intersection, it will trigger a vibration signal through the fiber optic cable when it passes the location of optical crossover B. The exact route of Line 2 can be determined. The fiber optic cable lengths at the two points, when it passes the lower right road and when it goes straight to optical crossover B, can also be measured.

[0099] 3) When the maintenance instrument is connected to the fiber optic cable of line 3, a vibration signal is generated at the end of the turn when car C turns right; there is no signal when car C turns left; a signal appears when it goes straight through optical cross-section B.

[0100] 4) When the maintenance instrument is connected to the fiber optic cable of line 4, when car C turns left, it will trigger a vibration signal at the beginning and end of the turn, and the positions are different but close; while when car C goes straight, there is only one vibration signal at the beginning; when it turns right, there is no obvious signal.

[0101] Figure 6 The method for determining the route direction by collecting fiber optic vibration signals from the movement of vehicles A, B, and D can be applied to the case of vehicle C. Generally, a drone only needs to stay on-site for 1-5 minutes to collect footage of several vehicles in motion, which is sufficient for multi-sample verification and route determination.

[0102] The fiber optic route finding device of this application can simultaneously receive on-site video transmitted by the drone and vibration signals uploaded by the maintenance instrument. According to the above determination method, it can make an instant and accurate determination of the fiber optic line to be detected (i.e. the line currently connected to the maintenance instrument).

[0103] In this embodiment, after obtaining the complete routing data of the optical fiber to be found, the following usage scenarios exist:

[0104] 1. Data can be synchronously transmitted to upper-level systems or third-party platforms via communication protocols, such as the resource management platform of mobile operators, the pipeline communication optical cable management system in the smart pipeline platform of oil and gas pipelines, and the power communication network management platform, to provide more accurate data for the management of communication optical fibers in various fields.

[0105] 2. A point-to-point fiber optic communication route map can be established. This involves drawing direct lines between various test locations. The coordinates of any point along the line can be plotted on the map proportionally based on the relationship between the fiber optic cable length and the fiber optic cable lengths of the two points, allowing for the estimation of the point's GPS coordinates. An example is as follows:

[0106] The map platform has already drawn the data according to Table 2. Figure 4 After obtaining the electronic map of the route, the fiber optic cable length for this route is L. f If a fault occurs at the location (significant fiber attenuation or breakpoint), the L value can be obtained using a commonly used OTDR, or the OTDR function of the intelligent maintenance instrument in this example. f If the actual value is obtained, the platform can obtain the GPS location of the fault point on the electronic map by following these steps, i.e., GPS f Specific parameters:

[0107] 1) Compare L f The relationship between the fiber optic lining lengths at each calibrated point in Table 2, confirmed by sorting, indicates that their fiber optic lining lengths fall between Lb and LC, corresponding to... Figure 4 Between the b-cable well and the C-road crossing point.

[0108] 2) L can be obtained using the following formula. f In L b and L C The position coefficient between them is denoted as k. f in b C .

[0109] (1)

[0110] 3) Let M be the direct distance between the lines connecting X and Y on the map. XY The location of a point on the map is obtained using the following formula for drawing line segments:

[0111] (2)

[0112] The location of point f on the map can be determined as being on the line connecting points b and C, at a distance Mf from point b. b The location of point f. Point f can be accurately located and plotted on the map, thus its GPS coordinates can be obtained. f .

[0113] 3. After the fiber optic management platform in various fields imports the electronic map of the searched lines, for various online or offline fiber optic detection systems, such as offline handheld OTDRs, online OTDRs, and online distributed fiber optic sensing systems, the fiber optic cable length of the detected fiber optic faults or external damage warning events can be transmitted to the fiber optic management platform. The GPS coordinate data can then be obtained through the method in point 2 above, thereby providing on-site management personnel with rapid location guidance and significantly improving the accuracy and timeliness of fiber optic fault location and repair.

[0114] This application also provides an apparatus for locating fiber optic routes. The apparatus includes a preset test location acquisition module, a full-line vibration signal acquisition module for the fiber to be located, and a full-line routing data generation module. The preset test location acquisition module is used to acquire preset test locations of the fiber to be located. The full-line vibration signal acquisition module is used to acquire the full-line vibration signals of the fiber to be located collected by the intelligent operation and maintenance instrument at each preset test location during the occurrence of a special event. The full-line routing data generation module is used to determine the full-line routing data of the fiber to be located based on the full-line vibration signals of the fiber to be located collected by the intelligent operation and maintenance instrument at each preset test location during the occurrence of a special event.
