Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, equipment, medium and product for manufacturing a hollow-core optical fiber cable. Background Art

[0002] The characteristic of hollow-core optical fiber is that the central part is hollow, and the light is transmitted through the hollow part. Unlike traditional solid optical fiber, the optical signal propagation of hollow-core optical fiber is carried out in a vacuum or gas-filled cavity, rather than in the core of solid material, which makes hollow-core optical fiber have lower light transmission loss and higher transmission efficiency.

[0003] At present, after the hollow-core optical fiber is cabled, rubber plugs need to be added at both ends of the hollow-core optical fiber cable. This results in the rubber plugs at the ends of the hollow-core optical fiber cable being easily damaged during the construction process. Once damaged, water and impurities in the pipeline will enter the hollow-core optical fiber, which will cause damage to the anti-resonance cavity and make the hollow-core optical fiber unusable. In addition, since rubber plugs are added at both ends of the hollow-core optical fiber, during the construction process, a mesh sleeve is needed to fix the hollow-core optical fiber cable for traction construction. Since the mesh sleeve is thicker than the optical cable, the duty cycle of the pipe hole is increased, the friction force is increased, and it is difficult to penetrate the small pipe, which significantly increases the construction difficulty and construction cost. In addition, since there are rubber plugs at both ends of the hollow-core optical fiber, single-disk testing cannot be performed, and it is difficult to determine the quality of the hollow-core optical fiber before construction. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a method, device, equipment, medium and product for manufacturing a hollow-core optical fiber cable. By forming a solid optical fiber segment in the hollow-core optical fiber, the quality of the hollow-core optical fiber cable can be effectively improved, the quality of the hollow-core optical fiber can be detected before construction, and the construction difficulty and construction cost can be reduced.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] See also Figure 1 , is a flow chart of a method for manufacturing a hollow-core optical fiber cable provided in an embodiment of the present invention. The embodiment of the present invention provides a method for manufacturing a hollow-core optical fiber cable, and the method includes steps S11 to S12:

[0047] S11, during or after the drawing of the hollow-core optical fiber, performing a high-temperature hot-melt taper process on the hollow-core optical fiber to form a solid optical fiber segment;

[0048] S12, cabling the hollow-core optical fiber to form a hollow-core optical fiber cable.

[0049] In the embodiment of the present invention, a hollow-core optical fiber is first produced. The structure of the hollow-core optical fiber is consistent with that of the existing hollow-core optical fiber, which is not specifically limited here.

[0050] Next, during the production process of the hollow-core optical fiber, an additional process operation is added to the two ends of the hollow-core optical fiber, that is, the two ends of the hollow-core optical fiber are converted into solid optical fiber segments by a high-temperature hot-melt taper method, so as to achieve the sealing of the two ends of the hollow-core optical fiber. Specifically, during the drawing process of the hollow-core optical fiber or after the drawing is completed, the hollow-core optical fiber is subjected to a high-temperature hot-melt taper treatment to form a solid optical fiber segment to obtain a new hollow-core optical fiber. Preferably, the length of the solid optical fiber segment should be greater than or equal to 20 cm and less than or equal to 100 cm. It should be noted that the high-temperature hot-melt taper treatment process should be avoided under complex external environments on site to avoid the formation of water vapor or the entry of impurities inside the hollow-core optical fiber, which may damage the hollow-core optical fiber.

[0051] Finally, the new hollow-core optical fiber after the tapered process is cabled to form a hollow-core optical fiber cable.

[0052] Preferably, the cabling processing methods include but are not limited to layer-twisted, central tube, and skeleton-type cabling methods.

[0053] In the embodiment of the present invention, since the two ends of the hollow-core optical fiber are subjected to high-temperature hot-melt taper processing to form a solid optical fiber segment, the cabling method of the new hollow-core optical fiber can be consistent with the existing solid optical fiber production layer-stranded optical cable, which has structures such as a central reinforcement member, a loose tube, a filling grease, and an outer sheath.

[0054] Taking the layer-twisted type as an example, the cabling process is as follows: the novel hollow-core optical fiber is placed in a loose tube. The loose tube is usually made of soft plastic material to protect the optical fiber from mechanical damage and environmental influences. Fill the loose tube with ointment or gel to increase the buffering effect of the optical fiber, reduce the microbending loss between optical fibers, and prevent moisture intrusion. The loose tube containing the optical fiber is twisted around a central reinforcement member (such as steel wire or aramid fiber). The central reinforcement member provides the main mechanical strength of the optical cable to ensure that the optical cable is not easily damaged under external forces such as stretching and bending. During the twisting process, the twisting pitch and twisting direction will be adjusted according to the design requirements of the optical cable to achieve the best transmission performance and mechanical properties. Fill the twisted cable core with water-blocking materials, such as ointment or water-blocking yarn, to improve the waterproof performance of the optical cable. Use a wrapping tape (such as a polyester tape) to wrap the cable core to further fix the optical fiber position and prevent the optical fiber from moving inside the optical cable. An outer sheath is coated on the cable core, usually made of polyethylene (PE), polyvinyl chloride (PVC) or other plastic materials with good weather resistance. The outer sheath not only provides external protection for the optical cable, but also determines the appearance and color of the optical cable. During the extrusion process, the thickness and uniformity of the outer sheath need to be controlled to ensure the overall quality and performance of the optical cable.

[0055] By adopting the technical means of the embodiment of the present invention, during the drawing process of the hollow-core optical fiber or after the drawing is completed, before storage or cabling, the two ends of the hollow-core optical fiber are treated with high-temperature hot-melt taper to form solid optical fiber segments, so as to achieve the blocking of the two ends of the hollow-core optical fiber, which can avoid the easy entry of moisture or impurities due to the central control of the middle of the hollow-core optical fiber, causing damage to the hollow-core optical fiber, and can also avoid wear and tear, solving the problem of using rubber plugs for blocking in the prior art, and the rubber plugs are easily worn and damaged during the construction process, resulting in the entry of moisture or impurities. In addition, since the two ends of the new hollow-core optical fiber are solid optical fibers, the storage conditions and cabling conditions are consistent with those of the solid-core optical fiber, making full use of the existing solid-core optical fiber industry chain technology to maximize benefits. During the construction process, a conventional construction method can be used, that is, stripping the hollow-core optical fiber cable to expose the central reinforcement member, connecting the central reinforcement member to a pipe cleaner for traction, and realizing manual or mechanical laying of the pipeline optical cable, which solves the problem of increased construction difficulty and construction cost caused by the use of mesh sleeves for traction construction in the prior art. The embodiment of the present invention inherits the existing solid optical fiber cable industry chain, and also guarantees the quality of hollow-core optical fiber cables, effectively reduces construction difficulty and cost, improves construction efficiency, and guarantees the quality of hollow-core optical fibers during the construction process.

[0056] As a preferred implementation, the present invention is further implemented on the basis of the above-mentioned embodiment, and the high-temperature hot-melt taper processing process of the hollow-core optical fiber is further optimized.

[0057] In a preferred embodiment, during the drawing process of the hollow-core optical fiber, the hollow-core optical fiber is subjected to a high-temperature hot-melt taper process to form a solid optical fiber segment, comprising:

[0058] During the hollow core optical fiber drawing process, obtaining the drawing length sensed by the length counter on the drawing tower;

[0059] When the drawing length reaches a preset length threshold, the high-temperature hot-melt device on the drawing tower is controlled to perform high-temperature hot-melt taper processing on the hollow-core optical fiber to form a solid optical fiber segment.

[0060] In an embodiment of the present invention, the drawing process of the hollow-core optical fiber is realized by a drawing tower. In addition, the drawing tower is provided with a controller, a length counter and a high-temperature hot-melt device, and the high-temperature hot-melt device is a device that can quickly extend and contract close to the drawing process and translate the hot-melt drawing cone at the same drawing speed. During the drawing process of the hollow-core optical fiber, the drawing length is calculated by the length counter. When the drawing length of the hollow-core optical fiber reaches the length required for cabling, that is, the preset length threshold, for example, 2 kilometers, the controller controls the high-temperature hot-melt device to start, and quickly melts the hollow-core optical fiber to form a solid optical fiber segment. During this process, the optical fiber is not interrupted, and the drawing continues, and then the next 2 kilometers are counted, and the cycle is repeated in sequence until all the drawing is completed, and then the two ends of the solid optical fiber are subjected to high-temperature hot-melt drawing cone processing to form solid optical fiber segments at both ends. After that, in the cabling process, the solid optical fiber segments at every 2 kilometers can be cut to form multiple segments of optical fiber.

[0061] Preferably, the length counter is provided with a speed sensor. Then, obtaining the drawing length sensed by the length counter on the drawing tower comprises:

[0062] The speed sensor senses the drawing speed of the hollow core optical fiber;

[0063] The drawing length is obtained by calculation according to the drawing speed.

[0064] By adopting the technical means of the embodiment of the present invention, the solid optical fiber segment is formed during the drawing process of the hollow-core optical fiber, and the length of the hollow-core optical fiber cable can be configured in a standard manner, which is convenient to operate and highly efficient.

[0065] In another preferred embodiment, after the hollow-core optical fiber is drawn, the hollow-core optical fiber is subjected to a high-temperature hot-melt taper process to form a solid optical fiber segment, comprising:

[0066] After the hollow-core optical fiber is drawn, the fusion splicer is controlled to perform high-temperature hot-melt taper processing on the two ends of the hollow-core optical fiber to form a solid optical fiber segment.

[0067] In an embodiment of the present invention, after the hollow core optical fiber is drawn, before storage or cabling, the fusion splicer is controlled to perform high-temperature hot-melt taper processing on the two ends of the hollow core optical fiber, and the two ends of the hollow core optical fiber are quickly melted and shrunk into solid optical fiber segments.

[0068] Since the length of hollow-core optical fiber drawing is much longer than the length of hollow-core optical fiber cabling, after the hollow-core optical fiber drawing is completed and before cabling, only the two ends of the hollow-core optical fiber are sealed to ensure the quality of the hollow-core optical fiber during storage. When cabling is required, the hollow-core optical fiber is cut as needed, and then the two ends of the cut hollow-core optical fiber are sealed by a fiber fusion splicer.

[0069] By adopting the technical means of the embodiment of the present invention, the solid optical fiber segments at both ends are formed after the drawing of the hollow-core optical fiber is completed, and the length of the hollow-core optical fiber can be configured as needed, but it needs to be split again before the cabling process to meet the usage requirements.

[0070] As a preferred implementation, the embodiment of the present invention is further implemented on the basis of any of the above embodiments. In step S12, that is, after the hollow-core optical fiber is cabled to form a hollow-core optical fiber cable, the method further includes:

[0071] A single reel test is performed on the hollow core optical fiber cable to evaluate the production quality of the hollow core optical fiber cable.

[0072] By adopting the technical means of the embodiment of the present invention, since the existing hollow-core optical fibers have rubber plugs at both ends and cannot be tested on a single reel, the new hollow-core optical fibers of the embodiment of the present invention have solid ends at both ends and can be tested at the factory or on a single reel, which can accurately judge the quality of the hollow-core optical fibers and solve the quality inspection problem of the hollow-core optical fibers before leaving the factory and entering the construction site.

[0073] Preferably, the single-reel test of the hollow-core optical fiber cable to evaluate the production quality of the hollow-core optical fiber cable comprises:

[0074] Controlling the laser and the optical power meter to perform an optical power test on the hollow-core optical fiber cable to obtain optical power data;

[0075] Calculate the conversion loss between the hollow-core fiber segment and the solid-core fiber segment of the hollow-core fiber cable according to the optical power data to obtain the link loss of the hollow-core fiber cable;

[0076] The production quality of the hollow-core optical fiber cable is evaluated based on the link loss.

[0077] In an embodiment of the present invention, a single-disk test is performed on a hollow-core optical fiber cable, a laser is connected to one end of the optical fiber as a light source input, and an optical power meter is connected to the other end of the optical fiber to measure the received optical power data. The link loss is calculated using the measured optical power value and the transmitted optical power value. Link loss = transmitted optical power - received optical power - conversion loss. Finally, the calculated link loss is compared with the specification sheet or relevant standards of the hollow-core optical fiber. If the link loss is within the allowable range, it means that the quality of the hollow-core optical fiber is good; if the link loss is too large, it may indicate that there is a quality problem with the optical fiber or an error in the test process, thereby evaluating the production quality of the hollow-core optical fiber cable.

[0078] As a preferred implementation, the embodiment of the present invention is further implemented on the basis of any of the above embodiments. In step S12, that is, after the hollow-core optical fiber is cabled to form a hollow-core optical fiber cable, the method further includes:

[0079] A mark is provided at the connection position of the hollow-core optical fiber segment and the solid-core optical fiber segment of the hollow-core optical fiber cable to mark the connection position of the hollow-core optical fiber segment and the solid-core optical fiber segment of the hollow-core optical fiber cable.

[0080] The method further comprises:

[0081] Cutting is performed at the markings, and two hollow-core optical fiber cables are fusion-joined.

[0082] In the embodiment of the present invention, after the hollow-core optical fiber cable is obtained through cabling, a mark may be added to the hollow-core optical fiber cable to facilitate construction, so as to mark the joint between the hollow-core optical fiber segment and the solid optical fiber segment.

[0083] In addition, if the new hollow-core optical fiber cable needs to be spliced ​​in the subsequent application process, the solid optical fiber segment can be cut off according to the mark to splice two hollow-core optical fiber cables.

[0084] Understandably, the solid core fiber segments at both ends of the hollow core fiber can also be directly spliced. If the solid core fibers at both ends of the hollow core fiber are spliced, it is consistent with the existing splicing method of solid core fibers, which improves the quality and efficiency of fusion splicing.
