[0032] In the description of the present application, unless otherwise specified, “plurality” means two or more.
[0033] Hollow-core optical fiber, with its exceptional properties of ultra-low loss, ultra-low dispersion, ultra-low nonlinearity, and low latency, is a key candidate for the development of next-generation ultra-high-capacity, low-latency, and high-speed optical communication systems. However, due to its hollow structure, when hollow-core optical fiber is laid in humid or submerged environments and breaks or ruptures, moisture inevitably enters the hollow space. This moisture can cause additional transmission loss or even communication interruption.
[0034] Unlike liquid water, water vapor mostly exists in gaseous form inside hollow-core optical fibers. Furthermore, due to the extremely weak backscattering inside hollow-core optical fibers, existing OTDRs are unable to detect water vapor inside hollow-core optical fibers to determine whether the hollow-core optical fibers are broken. Consequently, during maintenance of existing networks, the breakage / damage points of hollow-core optical fibers cannot be discovered in a timely manner.
[0035] In response to the above technical problems, the present application provides a fiber optic detection method, the idea of which is to collect fiber optic images of fibers that may be broken and have water vapor ingress, and based on the collected fiber optic images and the preset correspondence, determine whether the tested fiber optic has water vapor ingress, as well as the time and length of water vapor ingress.

[0050] It should be noted that the device described in the embodiments of the present application is intended to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of the device, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.
[0051] The optical fiber detection method of the embodiment of the present application is introduced below with reference to a specific embodiment.
[0052] Implementation method 1: Applicable to Figure 1In the fiber optic detection device shown, collimator 201 directs light emitted by light source 101 horizontally through a water vapor-infused fiber. Objective lens 102 receives the light and transmits it to image collector 203. Image collector 103 obtains a side view of the water vapor-infused fiber and transmits this view to processing unit 104, connected to image collector 103, to calculate pixel feature values of the fiber image. A water vapor-infused fiber is prepared, and side images of the water vapor-infused fiber are obtained at various locations at different distances from the water inlet end of the water vapor-infused fiber. Processing unit 104 obtains the image pixel feature values and establishes a correspondence between the image pixel feature values and the water vapor-infused length of the hollow-core fiber, thereby achieving a correspondence between the side image of the water vapor-infused fiber and the water vapor-infused length of the hollow-core fiber.
[0053] Implementation method 2: Applicable to Figure 2 In the optical fiber detection device shown, light emitted by light source 101 is collimated by collimator 201 and then directed toward reflector 301. Mirror 301 reflects the light and transmits it through the water vapor-infused optical fiber. Objective lens 102 receives the light and enters image acquisition device 103. Image acquisition device 103 obtains a side view of the water vapor-infused optical fiber 3 and transmits the side view to processing unit 104 connected to image acquisition device 103 to calculate image pixel feature values. A batch of hollow-core optical fibers with different water vapor infusion durations are prepared, positioned at the same distance from the water inlet end of each water vapor-infused optical fiber. Side images of the water vapor-infused hollow-core optical fibers are sequentially acquired. Processing unit 104 sequentially acquires image pixel feature values and establishes a correspondence between the image pixel feature values and the water vapor infusion duration of the optical fiber, thereby achieving a correspondence between the side images of the water vapor-infused hollow-core optical fiber and the water vapor infusion duration of the hollow-core optical fiber.
[0054] Implementation method three, which can be applied to the embodiments of this application, such as Figure 4 In another fiber optic detection device shown, collimator 201 directs light emitted by light source 101 toward the end face of a water vapor-infused fiber. Light reflected from this end face is received by objective lens 102 and enters image acquisition device 103. Image acquisition device 103 obtains an end face image of the water vapor-infused fiber and transmits this end face image to processing unit 104 connected to image acquisition device 103 to calculate image pixel feature values. A batch of hollow-core optical fibers with varying water vapor infiltration durations are prepared, and end face images of the water vapor-infused fibers are sequentially acquired. Processing unit 104 sequentially acquires image pixel feature values and establishes a correspondence between the image pixel feature values and the water vapor infiltration duration of the hollow-core fibers, thereby achieving a correspondence between the end face images of the water vapor-infused fibers and the water vapor infiltration duration of the hollow-core fibers.
[0055] Figure 5 This is a flow chart of a fiber optic detection method provided in an embodiment of the present application. Figure 5 As shown, the sandbox reconstruction method provided by this application specifically includes S501-S502.
[0056] S501: Acquire an optical fiber image of an optical fiber to be inspected.
[0057] For example, in this application, the optical fiber to be inspected may be a hollow-core optical fiber, and the optical fiber image may be an image formed by light emitted by a light source passing through or reflected from the optical fiber. Specifically, the optical fiber image may be acquired from multiple locations along the optical fiber to be inspected. For selecting the inspection location, locations near where the optical fiber to be inspected wades through water or locations prone to breakage during installation may be selected.
[0058] S502: Determine a detection result based on the pixel feature values of the optical fiber image and a preset corresponding relationship.
[0059] The detection result indicates the water vapor ingress length and / or water vapor ingress time of the optical fiber to be detected, and the corresponding relationship indicates the corresponding relationship between the pixel characteristic value of the optical fiber image and the water vapor ingress length and / or water vapor ingress time of the optical fiber.
[0060] Under normal circumstances, the interior of an optical fiber is a gas. When water vapor enters, this vaporized liquid water may adhere to the fiber's interior, forming droplets. It may also form floating droplets. These droplets will cause diffuse reflection, resulting in pixel feature values in the optical fiber image differing from those in normal conditions. Specifically, the pixel feature value can be the color or chromaticity value of the optical fiber image pixel. For grayscale images, this can be the brightness value of the pixel, while for RGB images, it can be the color value of the RGB channels.
[0061] In some embodiments, when the optical fiber's water vapor inlet time reaches a threshold, its water vapor inlet length stabilizes and no longer changes. The optical fiber's water vapor inlet length can be the length of the optical fiber from the location where the fiber breaks to the farthest point where water vapor can be detected. In practical applications, when a break occurs at a certain location in the optical fiber, water vapor will diffuse from that location to both ends. In other words, the optical fiber's water vapor inlet length, as defined in this application, can refer to the optical fiber's water vapor inlet length on one side of the break. Generally, the optical fiber's water vapor inlet length is positively correlated with the water vapor inlet time, but as the water vapor inlet time increases, the rate of increase in the optical fiber's water vapor inlet length gradually decreases.
[0062] In some embodiments, the presence of water vapor at the detection location is determined by analyzing the pixel characteristic values of the acquired optical fiber image in conjunction with a preset correspondence. For example, the concentration of water vapor entering the optical fiber can be negatively correlated with the distance from the break location; that is, the closer to the break location, the greater the water vapor concentration within the optical fiber. It is understood that the water vapor concentration also affects the pixel characteristic values of the optical fiber image. Based on this principle, the presence of water vapor at the current detection location, as well as the duration or duration of water vapor intrusion, can be determined by using the correspondence between the pixel characteristic values of the optical fiber image and the time and / or length of water vapor intrusion, as defined in the preset relationship.
[0063] The technical solutions provided by the above embodiments bring at least the following beneficial effects. The optical fiber detection method provided in the present application obtains an optical fiber image of the optical fiber to be detected, analyzes its pixel characteristic values, and combines it with a preset correspondence to determine whether water vapor has entered the optical fiber to be detected, as well as the time and length of water vapor entry, thereby solving the current problem of being unable to detect water vapor entering the optical fiber.
[0064] In some embodiments, the correspondence is constructed based on a first image set, which includes a plurality of first optical fiber images, where collection positions of the plurality of first optical fiber images on the optical fiber are at different distances from positions of the water vapor inlet end.
[0065] When constructing the first image set, a given first optical fiber sample can be used. The fracture position of the first optical fiber sample is known. By sampling at different distances from the fracture position of the first optical fiber sample, the corresponding first optical fiber image is obtained. The corresponding relationship between the pixel characteristic value of the optical fiber image and the distance from the water vapor inlet end position is determined by the obtained first optical fiber image and the corresponding sampling position. For example, when the first optical fiber image is a grayscale image, the first image collected at 0.2 meters from the water vapor inlet end has a grayscale value of less than 120. The proportion of pixels with a grayscale value of less than 120 in the first image collected at 0.4 meters from the water vapor inlet end exceeds 40% to 50%. Similarly, the corresponding relationship between the pixel characteristic value of the optical fiber image and the water vapor inlet length of the optical fiber is established.
[0066] In some embodiments, the acquired first optical fiber image can be annotated, for example: 0.2 meters away from the water vapor inlet end, grayscale values less than 120 pixels account for 60%, grayscale values 120-180 pixels account for 35%, and grayscale values greater than 200 account for 15%. The annotation content is not limited to the listed content, and can also include sampling date, sampling optical fiber model, weather information of the day, etc.
[0067] The technical solutions provided by the above embodiments bring at least the following beneficial effects. The optical fiber detection method provided in this application establishes the relationship between the pixel characteristic values of the optical fiber image and the water vapor inlet length through a pre-acquired image set, which facilitates the subsequent application to quickly and directly determine the water vapor inlet condition of the optical fiber based on the actually acquired optical fiber image.
[0068] In some embodiments, the corresponding relationship is constructed based on a second image set, which includes multiple second optical fiber images. The multiple second optical fiber images are respectively collected at target positions of multiple optical fibers. The water vapor inlet times of the multiple optical fibers are different, and the distance between the target position and the water vapor inlet end of the optical fiber is greater than or equal to a preset distance.
[0069] In some embodiments, a second image set can be constructed using multiple second fiber samples. Specifically, the water vapor inlet timing of each of the multiple second fiber samples differs. For any given second fiber sample, multiple target sampling locations can be set. For example, locations on the second fiber sample 0.2 meters, 0.4 meters, and 0.6 meters from the water vapor inlet can be set as target locations, and corresponding second fiber images can be captured. The target locations for capturing fiber images of the multiple second fiber samples can be the same or different.
[0070] In some embodiments, the second optical fiber image in the second image set can also be annotated, for example, the water vapor inlet time is 1 day, the distance from the water vapor inlet end is 0.2 meters, etc. The annotation method of the first optical fiber image in the aforementioned embodiment can be referred to and will not be repeated here.
[0071] The technical solutions provided by the above embodiments bring at least the following beneficial effects. The optical fiber detection method provided in this application establishes the relationship between the pixel characteristic values of the optical fiber image and the water vapor ingress time through a pre-acquired image set, which facilitates the subsequent application to quickly and directly determine the water vapor ingress condition of the optical fiber based on the actually acquired optical fiber image.
[0072] In some embodiments, the optical fiber image includes a side view and / or an end view of the optical fiber.
[0073] For example, when inspecting an optical fiber with unknown moisture ingress, the image obtained may be a side view of the fiber. This image is formed by the light from the light source passing through the fiber. Technicians can then cut off a portion of the fiber based on the moisture ingress and re-inspect the fiber to confirm that the moisture-ingressed portion has been completely removed. The resulting image of the fiber can be an end-face view of the fiber, formed by the light from the light source reflecting off the cut end face of the fiber.
[0074] In some embodiments, when constructing the first image set and the second image set, the side view and the end view of the optical fiber may also be used simultaneously for construction.
[0075] The technical solutions provided by the above embodiments bring at least the following beneficial effects. The optical fiber detection method provided in this application can more accurately determine the water vapor ingress situation of the optical fiber by obtaining the side view and end view of the optical fiber, and assist technicians in handling broken optical fibers.
