Abstract

This invention discloses an optical fiber laying carrier and an optical fiber laying method, relating to the field of optical fiber laying technology. The optical fiber laying carrier includes a flexible plate with a laying working surface for laying optical fibers. An adhesive layer is disposed on the laying working surface, configured to temporarily adhere the optical fiber to fix its position during the laying process. By using a flexible plate with a temporary adhesive layer as the laying carrier, the optical fiber position is temporarily fixed only during the laying process. After the entire optical fiber laying is completed and bundled, the flexible plate can be separated from the optical fiber, enabling the recycling and reuse of the laying carrier without permanent bonding with the optical fiber.

Furthermore, the temporary fixing effect of the adhesive layer improves the positional stability of the optical fiber during laying, ensuring accurate laying along a predetermined path.

Description

Technical Field

[0001] This invention relates to the field of optical fiber fabrication technology, and in particular to an optical fiber fabrication carrier and an optical fiber fabrication method. Background Technology

[0002] In fiber optic communication, data interconnection, and fiber optic sensing systems, the deployment and assembly of optical fibers typically require permanent positioning and fixation using carriers. Current conventional fiber deployment processes often employ fixed base plates to support the optical fibers and then bond them together with adhesive. After deployment, the base plate and optical fiber are cured together with the adhesive layer and cannot be separated independently. The base plate cannot be recycled or reused, resulting in high material consumption and production costs. Summary of the Invention

[0003] The main objective of this invention is to propose an optical fiber carrier and an optical fiber laying method, aiming to solve the technical problem that existing conventional fiber laying processes often use a fixed base plate to carry the optical fiber and cure it with adhesive, in which the base plate and the optical fiber are bonded together by the adhesive layer and cannot be separated independently.

[0004] To achieve the above objectives, the fiber optic cable carrier proposed in this invention includes a flexible plate, the flexible plate having a fiber laying working surface for laying optical fibers, and an adhesive layer disposed on the fiber laying working surface, the adhesive layer being configured to temporarily adhere the optical fibers so that the position of the optical fibers is fixed during the fiber laying process.

[0005] In one embodiment, the adhesive layer is either a peelable non-curing adhesive layer or an electrostatic adsorption layer.

[0006] In one embodiment, the flexible plate is enclosed to form a central hole for accommodating a portion of an optical fiber.

[0007] In one embodiment, the flexible plate has an annular structure, and the radial distance from the inner edge to the outer edge of the flexible plate is equal everywhere.

[0008] In one embodiment, the optical fiber carrier further includes a fiber base, and the flexible plate is disposed on the top wall of the fiber base; The top wall of the fiber base is also provided with a clearance hole, which is connected to the central hole.

[0009] In one embodiment, the outline size of the clearance hole is greater than or equal to the outline size of the center hole, and the outline of the center hole is located within the outline of the clearance hole.

[0010] This invention also proposes an optical fiber laying method, based on the optical fiber laying carrier described above, comprising the following steps: Provide the flexible plate; Provides multiple optical fibers; Multiple optical fibers are laid out on the fiber-laying working surface according to a predetermined path so that the optical fibers adhere to the adhesive layer; Multiple optical fibers located outside the outline of the flexible plate are bundled and fixed to obtain bundled fixed optical fibers; Separate the flexible plate from the bundled fixed optical fiber.

[0011] In one embodiment, the flexible plate has a circular ring structure, and a central hole is formed around the flexible plate. The radial distance from the inner edge to the outer edge of the flexible plate is equal everywhere. The optical fiber has an input segment, a reserved segment, and an output segment connected in sequence. The step of laying multiple optical fibers on the fiber laying working surface according to a predetermined path specifically includes the following steps: The input segments of the multiple optical fibers are divided into M input groups, and the output segments of the multiple optical fibers are divided into N output groups, where M and N are both positive integers. The multiple input segments of each input group are arranged along a radial direction of the flexible plate, and the input segments in different input groups are arranged along different radial directions of the flexible plate; The multiple output segments of each output group are arranged along another radial direction of the flexible plate, and the output segments in different output groups are arranged along different radial directions of the flexible plate.

[0012] In one embodiment, the fiber optic fiber carrier further includes a fiber optic base, the flexible plate is disposed on the top wall of the fiber optic base, and the top wall of the fiber optic base is also provided with a clearance hole, the clearance hole communicating with the central hole; After the step of laying the multiple optical fibers on the fiber laying working surface according to a predetermined path, the following steps are also included: The reserved sections of multiple optical fibers are housed within the central hole and the clearance hole.

[0013] In one embodiment, the step of bundling and fixing the plurality of optical fibers located outside the outline of the flexible plate can be achieved by at least one of cable ties, sleeves, or tape.

[0014] The technical solution of this invention uses a flexible plate with a temporary adhesive layer as a fiber laying carrier. The position of the optical fiber is temporarily fixed only by the adhesive layer during the fiber laying process. After the overall fiber laying is completed and bundled, the flexible plate can be peeled off from the optical fiber, realizing the recycling and reuse of the fiber laying carrier. It does not need to be permanently integrated with the optical fiber, effectively reducing the material consumption and production cost of fiber laying operations. At the same time, relying on the temporary fixing effect of the adhesive layer, the positional stability of the optical fiber is better during the fiber laying process, which can ensure that the optical fiber is accurately laid according to the predetermined path, reduce fiber laying errors, improve the regularity of the optical fiber laying and the performance stability of the finally assembled optical fiber device.

[0022] This invention proposes an optical fiber carrier 100.

[0023] Please see Figure 1 In one embodiment of the present invention, the optical fiber carrier 100 includes a flexible plate 1, the flexible plate 1 having a fiber laying working surface 11 for laying optical fibers 210, and an adhesive layer 2 is provided on the fiber laying working surface 11. The adhesive layer 2 is configured to temporarily adhere the optical fibers 210 so that the position of the optical fibers 210 is fixed during the fiber laying process.

[0024] Specifically, the flexible plate 1 is a sheet-like substrate with flexible deformation capabilities, which can be made of polyester, polyimide, or flexible polymer materials. The thickness of the plate can be set from 0.1 mm to 2 mm. This thickness can maintain the flatness of the plate surface, providing a stable path reference plane for the laying of the optical fiber 210, and can also be completely removed from under the optical fiber 210 by bending and lifting the edges after the fiber laying is completed. It should be noted that the flexible plate 1 can take the shape of square, round, or irregular shapes, etc., and this embodiment does not limit it.

[0025] The fiber laying working surface 11 is a flat surface of the flexible plate 1 facing the fiber laying operation side. All the laying paths of the optical fiber 210 fall within the range of the fiber laying working surface 11. The automated fiber laying equipment can use the fiber laying working surface 11 as the fiber laying reference surface to perform the wiring operation.

[0026] The adhesive layer 2 is formed by uniformly coating an adhesive material onto the fiber laying surface 11. Optionally, the coating thickness can be controlled between 5 μm and 50 μm. The adhesive layer 2 is configured to temporarily adhere the optical fiber 210 and ensure its position is fixed during fiber laying. Optionally, the adhesive layer 2 can use a non-curing adhesive formulation, which does not undergo cross-linking curing reaction after coating and is bonded to the outer cladding surface of the optical fiber 210 only through intermolecular physical adsorption forces. Optionally, its peel force per unit width on the outer cladding of the optical fiber 210 can be adjusted within the range of 0.05 N / cm to 0.5 N / cm.

[0027] During the fiber laying process, when the fiber outlet of the fiber laying equipment presses the optical fiber 210 onto the fiber laying working surface 11 and follows the preset path, the adhesive force can provide sufficient positional constraint on the optical fiber 210. This force can resist the rebound force of the optical fiber 210 itself, the micro-vibration of the equipment operation, and the slight contact of subsequent processes, maintaining the preset laying position of the optical fiber 210 without deviation or misalignment, and ensuring the accuracy of the fiber laying path. At the same time, the adhesive force is insufficient to form a permanent bond with the optical fiber 210. After the fiber laying is completed, the flexible plate 1 can be completely removed from under the optical fiber 210. During the removal process, the optical fiber 210 will not be pulled, the optical fiber 210 body will not be damaged, and the laying length of the optical fiber 210 will not be changed.

[0028] In one embodiment of the present invention, the adhesive layer 2 is either a peelable non-curing adhesive layer or an electrostatic adsorption layer.

[0029] It should be noted that when using a peelable, non-curing adhesive layer, non-crosslinking curing adhesives such as acrylic pressure-sensitive adhesives or silicone pressure-sensitive adhesives can be selected and uniformly applied to the surface of the fiber-laying working surface 11 using roller coating or blade coating processes. Optionally, the film thickness of the adhesive layer can be controlled between 5 μm and 50 μm. This type of adhesive layer does not undergo a chemical crosslinking curing reaction; it relies solely on intermolecular forces to bond and fix the optical fiber 210, with a peel force stable in the range of 0.05 N / cm to 0.5 N / cm. When the flexible plate 1 is removed after fiber laying, the adhesive layer remains intact on the fiber-laying working surface 11, with no adhesive residue on the outer surface of the optical fiber 210 and no damage from pulling; the adhesive layer's own structure is not damaged, its adhesive performance is not easily degraded, and it can be recycled for subsequent fiber-laying operations.

[0030] When using an electrostatic adsorption layer, it can be formed by electret polarization treatment of the fiber-laying working surface 11 of the flexible plate 1, or by attaching a permanent electrostatic adsorption film to the fiber-laying working surface 11. The electrostatic adsorption layer achieves temporary positioning of the optical fiber 210 by relying on the electrostatic attraction between the surface static charge and the outer cladding of the optical fiber 210, without the need for adhesive coating and without the problem of adhesive layer transfer residue. It can provide sufficient adsorption force to maintain the stable position of the optical fiber 210 during fiber laying, and there is no adhesion resistance when removing the flexible plate 1, so as not to cause mechanical stress to the optical fiber 210.

[0031] Please refer to further information. Figure 2 In one embodiment of the present invention, the flexible plate 1 is enclosed to form a central hole 1a, which is used to accommodate a portion of the optical fiber 210.

[0032] In this embodiment, a central hole 1a penetrating the thickness of the flexible plate 1 is formed in the middle of the plate. The inner edge of the central hole 1a and the outer edge of the flexible plate 1 together form a fiber-laying working surface 11 surrounding the central hole 1a. The diameter of the central hole 1a can be flexibly set according to the number of optical fibers 210 in a single fiber laying and the length of the reserved section 212 of a single optical fiber 210, ensuring that the reserved sections 212 of all optical fibers 210 can be completely accommodated in the space inside the hole. This embodiment does not limit this.

[0033] It should be noted that the automatic fiber laying equipment can calculate and reserve the necessary adjustment length for each fiber or group of optical fibers 210 based on the preset path length and the adjustment margin for subsequent assembly, thus forming a reserved section 212 for the optical fiber 210. After the optical fiber 210 is laid along the annular fiber laying working surface 11, the reserved section 212 naturally hangs down towards the central hole 1a and is stored in the internal space of the central hole 1a.

[0034] Understandably, the central hole 1a forms a recessed accommodating space along the thickness direction of the plate, which can restrict all the reserved sections 212 of the optical fiber 210 to the area below the fiber laying working surface 11, so that the highest point of the reserved section 212 never exceeds the surface of the fiber laying working surface 11. This completely avoids the reserved section 212 from interfering with the operation of the fiber output head of the automated fiber laying equipment after it tilts upward, ensuring that the fiber output head can run smoothly and continuously along the fiber laying working surface 11, thereby improving the operation accuracy and production efficiency of automated cabling.

[0035] Please refer to further information. Figure 3 In one embodiment of the present invention, the flexible plate 1 has a ring-shaped structure, and the radial distance from the inner edge to the outer edge of the flexible plate 1 is equal everywhere.

[0036] It should be noted that the flexible plate 1 in this embodiment adopts a ring-shaped structure. The flexible plate 1 is ring-shaped as a whole, and the outer contour of the plate is circular. The central hole 1a is also circular and is concentrically set with the outer contour of the flexible plate 1, so that the radial distance from the inner edge of the flexible plate 1 to the outer edge of the flexible plate 1 is equal everywhere. The purpose is to ensure that the laying path length of each group of optical fibers 210 is equal from a geometric perspective.

[0037] Understandably, the annular structure possesses the inherent geometric characteristic of radial equidism, meaning that the straight-line distance from the inner edge of the central hole 1a to the outer edge of the flexible plate 1 is equal in any radial direction. When the optical fiber 210 is laid along the radial path, the effective wiring length of each group of optical fibers 210 on the fiber laying working surface 11 is completely consistent. Without additional manual calibration, the physical length of multiple optical fibers 210 can be made equal, thereby ensuring a high degree of consistency in the optical signal transmission delay of each channel.

[0038] Please continue reading. Figure 2 In one embodiment of the present invention, the fiber optic fiber carrier 100 further includes a fiber optic base 3, a flexible plate 1 is disposed on the top wall of the fiber optic base 3, and the top wall of the fiber optic base 3 is also provided with a clearance hole 3a, which is connected to the central hole 1a.

[0039] Optionally, the fiber optic base 3 can be made of a rigid material with stable structural strength. Its main function is to provide rigid support and installation reference for the flexible plate 1, ensuring that the fiber optic working surface 11 of the flexible plate 1 remains horizontal and flat, preventing undulations on the surface of the flexible plate 1 due to its own flexibility, and ensuring the flatness accuracy of the fiber optic path. The overall contour of the fiber optic base 3 is adapted to the outer contour of the flexible plate 1, ensuring that the flexible plate 1 can be stably placed against the top wall of the base and will not shift during the laying operation.

[0040] The clearance hole 3a is located at the center of the top wall of the fiber-laying base 3, and its position corresponds one-to-one with the center hole 1a of the flexible plate 1. The cavities of the two holes are interconnected, forming a continuous recessed accommodating space. The fiber-laying base 3 has a certain thickness. Through the elevation effect of the base, the clearance hole 3a can extend downward to accommodate the depth of the center hole 1a, significantly increasing the accommodating length of the fiber optic 210 reserved section 212. After the fiber optic 210 reserved section 212 is inserted into the center hole 1a, it can continue to extend downward into the clearance hole 3a without being blocked by the top surface of the base. This ensures that all fiber optic 210 reserved sections 212 can be completely sunk below the fiber-laying working surface 11, avoiding interference from the automated fiber-laying equipment.

[0041] Furthermore, in one embodiment of the present invention, the outline size of the clearance hole 3a is greater than or equal to the outline size of the center hole 1a, and the outline of the center hole 1a is located within the outline of the clearance hole 3a.

[0042] Specifically, both the clearance hole 3a and the central hole 1a are circular openings, with the diameter of the clearance hole 3a being greater than or equal to that of the central hole 1a. When assembling the flexible plate 1 and the fiber base 3, the flexible plate 1 is aligned and placed on the top wall of the fiber base 3, with the central hole 1a and the clearance hole 3a arranged coaxially. Since the opening size of the clearance hole 3a is not smaller than that of the central hole 1a, the entire opening area of ​​the central hole 1a completely corresponds to the opening range of the clearance hole 3a. The top wall of the base will not obstruct the lower diameter of the central hole 1a, forming a continuous accommodating channel that extends vertically and gradually expands downwards or has the same diameter.

[0043] This size-matching design reduces the accuracy requirements for assembly alignment. Even if there is a slight assembly misalignment between the flexible plate 1 and the fiber-laying base 3, the lower edge of the central hole 1a will not be blocked by the top wall of the base, ensuring that the reserved section 212 of the optical fiber 210 can smoothly descend into the receiving space. On the other hand, it avoids the reserved section 212 of the optical fiber 210 from scratching the hole wall during its descent, preventing the outer cladding of the optical fiber 210 from being scratched. At the same time, it prevents the reserved section 212 from being blocked by the hole wall and arching upwards, ensuring that all reserved sections 212 can be completely sunk below the fiber-laying working surface 11, and avoiding interference of the reserved section 212 protrusion with the operation of the fiber outlet of the automated fiber-laying equipment.

[0044] Please see Figure 4 The present invention also proposes an optical fiber laying method, which is based on the optical fiber laying carrier 100 described above, and includes the following steps: S1: Provide flexible board 1; S2: Provides multiple fiber optic cables 210; S3: Arrange multiple optical fibers 210 on the fiber laying working surface 11 according to a predetermined path so that the optical fibers 210 adhere to the adhesive layer 2. S4: Bundle and fix multiple optical fibers 210 located outside the outline of the flexible plate 1 to obtain bundled fixed optical fibers 200. S5: Separate the flexible plate 1 from the bundled fixed optical fiber 200.

[0045] Specifically, in step S1, the flexible plate 1 can be a flexible plate 1 with an adhesive layer 2 formed on its surface. The flexible plate 1 is laid flat on the work surface with the fiber laying working surface 11 facing upwards, serving as the reference bearing surface for the fiber optic cable 210 laying. This step uses the flat flexible plate 1 to construct a temporary carrier for the fiber laying operation, providing a stable planar reference for the subsequent fiber optic cable 210 laying and ensuring the flatness of the fiber laying path.

[0046] In step S2, fiber optic cables 210 can be selected according to the number of channels and transmission requirements in the cabling design. The corresponding specifications and quantity of fiber optic cables 210 are selected, and they are cut to a preset total length. The ends of the fiber optic cables 210 are then arranged, completing the material preparation before fiber laying. This step pre-matches the cabling requirements and configures the fiber optic cables 210 to ensure that subsequent fiber laying processes can be executed smoothly and continuously.

[0047] In step S3, multiple optical fibers 210 are laid out on the fiber laying working surface 11 according to a predetermined path. The step of adhering the optical fibers 210 to the adhesive layer 2 can be performed using automated fiber laying equipment. The fiber output head holds the end of the optical fiber 210 and moves at a constant speed above the fiber laying working surface 11 according to the pre-planned wiring path. During this movement, the fiber output head simultaneously presses the optical fiber 210 down and adheres it to the fiber laying working surface 11. The adhesive layer 2 temporarily fixes the optical fiber 210 to the preset path. This step relies on the temporary adhesive force of the adhesive layer 2 to maintain the stable position of the optical fiber 210 after laying, resisting the self-rebound force of the optical fiber 210 and the micro-vibrations of the equipment operation, preventing path deviation and accurately ensuring the positional and length accuracy of the fiber laying.

[0048] In step S4, after all optical fibers 210 are laid out, multiple optical fibers 210 are aligned and arranged on the outer side of the flexible plate 1. They are then bundled and fixed using cable ties, sleeves 220, or tape, forming a structurally stable bundled fixed optical fiber 200. This step completes the grouping and fixing of the optical fibers 210 on the outside of the flexible plate 1, ensuring that the optical fiber group maintains a defined relative position after being detached from the flexible plate 1, preventing scattering or misalignment, and facilitating subsequent assembly, connection, and use.

[0049] In step S5, starting from any edge of the flexible plate 1, the edge of the flexible plate 1 can be slowly lifted downwards, causing the adhesive layer 2 to gradually detach from the surface of the optical fiber 210. This process is continued along the contour of the flexible plate 1 until the entire flexible plate 1 is completely separated from the bundled and fixed optical fiber 200. Figure 4 As shown, Figure 4 This is the bundled fixed optical fiber 200 obtained after separation. The separation process in this step does not require pulling the optical fiber 210, so it will not damage the optical fiber 210 body or change the original laying length of the optical fiber 210. It can completely preserve the fiber laying accuracy. The structure and performance of the adhesive layer 2 of the flexible plate 1 that is peeled off are intact and can be directly recycled for the next fiber laying operation, effectively reducing the cost of consumables and meeting the requirements of green manufacturing.

[0050] Furthermore, in one embodiment of the present invention, the flexible plate 1 has a circular ring structure, and a central hole 1a is formed around the flexible plate 1. The radial distance from the inner edge to the outer edge of the flexible plate 1 is equal everywhere. The optical fiber 210 has an input segment 211, a reserved segment 212 and an output segment 213 connected in sequence. The steps of laying multiple optical fibers 210 on the fiber laying working surface 11 according to a predetermined path specifically include the following steps: S31: Divide the input segments 211 of multiple optical fibers 210 into M input groups and the output segments 213 of multiple optical fibers 210 into N output groups, where M and N are both positive integers. S32: Control the multiple input segments 211 of each group to be arranged along a radial direction of the flexible plate 1, and the input segments 211 in different groups to be arranged along different radial directions of the flexible plate 1; S33: Control the multiple output segments 213 of each output group to be arranged along another radial direction of the flexible plate 1, and the output segments 213 in different output groups are arranged along different radial directions of the flexible plate 1.

[0051] In this embodiment, the flexible plate 1 is a ring-shaped structure, with a central hole 1a enclosed within it. The radial distance from the inner edge to the outer edge of the flexible plate 1 is equal everywhere. Each optical fiber 210 has an input segment 211, a reserved segment 212, and an output segment 213 connected in sequence. The input segment 211 and the output segment 213 are the effective working segments laid on the annular fiber laying working surface 11. The reserved segment 212 is a length segment left by the automatic fiber laying equipment according to a preset adjustment margin for subsequent length calibration.

[0052] Specifically, in step S31, the input segments 211 of multiple optical fibers 210 are divided into M input groups, and the output segments 213 of multiple optical fibers 210 are divided into N output groups, where M and N are positive integers. Before the fiber laying operation, the optical fiber 210 grouping plan is completed according to the port configuration of the target interconnection architecture. The input ends of all optical fibers 210 are divided into M input groups, and the output ends are divided into N output groups. Each group contains a corresponding number of optical fibers 210, and the input and output port positions of each group are predetermined. This step can flexibly configure the number of groups and the number of cores per group according to actual interconnection needs, adapting to various optical interconnection network architectures from simple parallel to complex full crossover.

[0053] In step S32, multiple input segments 211 of each group are arranged along a radial direction of the flexible plate 1, and the input segments 211 in different groups are arranged along different radial directions of the flexible plate 1. Automated fiber-laying equipment can be used to perform the wiring, working sequentially according to preset grouping points. All input segments 211 of each group are arranged parallel to each other along the corresponding radial direction from the outer edge of the flexible plate 1 towards the central hole 1a. Multiple input segments 211 of the same group are arranged side by side on the same radial path. Different groups are arranged along independent radial directions at different angular positions on the annular fiber-laying working surface 11. In this way, utilizing the geometric characteristic that the radial distance of the annulus is equal everywhere, the laying length of the input segments 211 of each group on the fiber-laying working surface 11 is completely consistent, ensuring that the path length of each group of input segments 211 is equal from a geometric perspective.

[0054] In step S33, multiple output segments 213 of each output group are arranged along another radial direction of the flexible plate 1, and the output segments 213 in different output groups are arranged along different radial directions of the flexible plate 1, corresponding to a preset cross-connection relationship. All output segments 213 of each output group are arranged parallel to the outer edge of the flexible plate 1 from the direction of the central hole 1a along the target radial direction. Multiple output segments 213 of the same output group are arranged side by side on the same radial path. Different output groups are distributed at different angular positions on the annular fiber-laying working surface 11, and each is arranged along an independent radial direction. In this way, the laying length of all output segments 213 is also completely consistent based on the radial equidistant characteristics of the annulus. Combined with the equal length design of the input segment 211, the total path length of each optical fiber 210 on the fiber-laying working surface 11 is finally equal, and low-latency synchronous transmission of multi-channel optical signals can be achieved without additional manual calibration. It should be noted that the redundant optical fibers 210 located outside the outer contour of the flexible plate 1 can be subsequently cut off. Therefore, this step ensures that the optical fibers 210 within the outer contour of the flexible plate 1 have equal lengths, thus ensuring that the length of each optical fiber 210 in the bundled fixed optical fibers 200 after cutting is equal. For example, as... Figure 3 As shown, M=8 and N=8 can be set, with each incoming group containing two optical fibers 210, which are respectively connected to two outgoing groups, forming a high-density, equal-length, fully cross-connected network. However, it should be understood that the above is only an exemplary example and should not be regarded as a limitation of the present invention.

[0055] In conjunction with the previous embodiment, after step S33, once all the incoming and outgoing groups are deployed, multiple optical fibers 210 in the same incoming or outgoing group in the outer region of the outer contour of the flexible plate 1 will be aligned and arranged. They will be bundled and fixed by means of cable ties, sleeves 220, or tape wrapping to form a structurally stable bundled fixed optical fiber 200.

[0056] Furthermore, in one embodiment of the present invention, the fiber optic fiber carrier 100 further includes a fiber optic base 3, a flexible plate 1 is disposed on the top wall of the fiber optic base 3, and the top wall of the fiber optic base 3 is also provided with a clearance hole 3a, which communicates with the central hole 1a. After the step of laying multiple optical fibers 210 on the fiber laying working surface 11 according to a predetermined path, the following steps are also included: The reserved sections 212 of multiple optical fibers 210 are housed in the central hole 1a and the clearance hole 3a.

[0057] The fiber optic cable carrier 100 used in this embodiment also includes a cable base 3. A flexible plate 1 is disposed on the top wall of the cable base 3. The top wall of the cable base 3 is also provided with a clearance hole 3a, which communicates with the central hole 1a. Before the cable laying operation, the cable base 3 is first horizontally fixed at the work position, and then the annular flexible plate 1 is aligned and placed on the top wall of the cable base 3, so that the central hole 1a and the clearance hole 3a are coaxially connected, forming a continuously downward extending recessed accommodating space. The cable base 3 is made of a rigid material, which can provide stable horizontal support for the flexible plate 1, ensuring that the cable laying working surface 11 remains flat and without undulations, and improving the flatness accuracy of the wiring path.

[0058] After the step of laying multiple optical fibers 210 along a predetermined path on the fiber laying working surface 11, the following step is also included: storing the reserved sections 212 of the multiple optical fibers 210 in the central hole 1a and the clearance hole 3a. In specific execution, after the automatic fiber laying equipment completes the radial laying of the input section 211 and the output section 213 of each optical fiber 210, it simultaneously pushes the reserved section 212 located between the input section 211 and the output section 213 towards the central hole 1a, so that the reserved section 212 naturally hangs down by its own tension and enters the central hole 1a and the clearance hole 3a below in sequence.

[0059] The fiber optic base 3 has a certain thickness, allowing it to extend downwards to accommodate the depth of the space. Even if the reserved section 212 is long, it can be completely housed within the clearance hole 3a, ensuring that the highest point of all fiber optic reserved sections 212 is below the surface of the fiber optic working surface 11. This completely prevents the reserved section 212 from tilting upwards and interfering with the operation of the fiber output head of the automated fiber optic laying equipment, ensuring that the fiber output head can run continuously and smoothly along the fiber optic working surface 11, improving automated production efficiency and wiring accuracy. At the same time, the reserved section 212 is suspended and housed within the hole, preventing it from scraping against the hole wall, thus avoiding wear on the outer cladding of the fiber optic 210 and protecting the optical performance of the fiber optic 210 from being affected.

[0060] In one embodiment of the present invention, in the step of fixing multiple optical fibers 210 located outside the outline of the flexible plate 1, the multiple optical fibers 210 can be fixed by at least one of cable ties, sleeves 220 or tape.

[0061] When using cable ties for fixation, first align the corresponding groups of optical fibers 210 on the outside of the flexible plate 1 to form a neatly arranged bundle of optical fibers 210. Then, use nylon cable ties to wrap around and tighten the bundle of optical fibers 210. Cut off the excess cable tie ends to complete the fixation. Cable tie fixation is convenient and provides stable locking force, making it suitable for mass production scenarios with a large number of optical fibers 210 and a large bundle diameter. After fixation, the structure of the optical fiber 210 bundle is firm and not easily scattered or misaligned. If disassembly is required later, the cable ties can be quickly cut without damaging the optical fiber 210 itself.

[0062] When using sleeve 220 for fixation, the aligned fiber optic bundle 210 is inserted as a whole into a plastic sheath or heat-shrink tubing with a matching inner diameter. When using heat-shrink tubing, it is heated evenly to shrink and tightly hold the fiber optic bundle 210 in place. Using sleeve 220 for fixation results in a neat appearance of the fiber optic bundle 210 and also protects the outer cladding of the fiber optic 210 ends, preventing wear and scratches on the fiber optic 210 during subsequent transportation and assembly. This method is suitable for fiber optic 210 assemblies with high requirements for appearance and protection.

[0063] When using adhesive tape for fixation, insulating tape or polyimide tape is continuously wrapped along the axial direction of the fiber optic bundle 210 to bind multiple fibers 210 together. Tape fixation is flexible, allowing adjustment of the fixation position and wrapping density as needed. The additional bundle diameter after fixation is minimal, making it suitable for scenarios with tight deployment spaces and strict limitations on bundle diameter. It can also be used for localized supplementary fixation, and when used in conjunction with cable ties or sleeves 220, it further enhances fixation reliability.

[0064] All three fixing methods operate on the outer contour of the flexible plate 1, without touching the already laid fiber optic 210 path on the plate, and without damaging the fiber laying accuracy; after fixing, the relative positions of each group of fiber optics 210 are stable, and the fiber optic bundles will not be scattered or misaligned during the subsequent removal of the flexible plate 1, and the preset group arrangement relationship can be completely maintained.
