Abstract

The invention discloses an optical fiber with a cladding in a special shape. A cladding piece of the optical fiber is of a non-circular structure used for positioning a plurality of fiber cores. According to the invention, the cladding member of the non-circular structure is adopted to bind the plurality of fiber cores, and the inner wall of the non-circular structure is not an arc-shaped surface, so that when the plurality of fiber cores are in contact with the inner wall of the non-circular structure, the inner wall of the non-circular structure can position the plurality of fiber cores, and mutual movement of the plurality of fiber cores on the inner wall of the non-circular structure is avoided; and the phenomenon of difficult positioning is avoided.

Description

Technical Field

[0001] The invention relates to the technical field of optical fiber optics, in particular to an optical fiber with a cladding of a special shape. Background Art

[0002] Currently, the cladding of optical fibers on the market all adopts a circular design. The circular cladding makes it difficult to position the optical fiber during installation. When multiple optical fibers are arranged in bundles, the gaps between the circular claddings are large, resulting in a waste of space. Therefore, it is necessary to improve the above defects.

[0003] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0004] The purpose of the present invention is to provide an optical fiber with a special shaped cladding to solve the problems in the prior art proposed in the above background technology that the circular cladding wastes space during application, is difficult to position the optical fiber, and cannot assist in the close arrangement of multiple fiber cores.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The invention discloses an optical fiber with a cladding of a special shape, wherein the cladding of the optical fiber is a non-circular structure used for positioning a plurality of optical cores.

[0007] Furthermore, the core of the optical fiber is circular and is coaxially arranged with the cladding member of the non-circular structure.

[0008] Furthermore, the optical fiber in the cladding member is a single-core or multi-core structure.

[0009] Furthermore, the multi-core structures are evenly distributed in the cladding member and are in contact with each other.

[0010] Furthermore, the non-circular structure includes a polygonal shape for reducing the gap between the cladding and the core.

[0011] Furthermore, the non-circular structure also includes a flower shape or an irregular shape for arranging multiple fiber cores.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention bundles multiple fiber cores by using a cladding member with a non-circular structure. Since the inner wall of the non-circular structure is not an arc-shaped surface, when the multiple fiber cores contact the inner wall of the non-circular structure, the inner wall of the non-circular structure can position the multiple fiber cores, thereby preventing the multiple fiber cores from moving relative to each other on the inner wall of the non-circular structure, causing difficulty in positioning.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1

[0020] See also Figure 1-3 , the present invention provides a technical solution:

[0021] An optical fiber with a cladding of a special shape, wherein the cladding member 2 of the optical fiber is a non-circular structure used for positioning a plurality of fiber cores 1.

[0022] It should be noted that: by using a non-circular cladding member 2 to bundle multiple fiber cores 1, since the inner wall of the non-circular structure is not a curved surface, when the multiple fiber cores 1 contact the inner wall of the non-circular structure, the inner wall of the non-circular structure can position the multiple fiber cores 1, thereby avoiding the multiple fiber cores 1 from moving relative to each other on the inner wall of the non-circular structure, causing difficulty in positioning.

[0023] As an improvement, the core 1 of the optical fiber is circular and is coaxially arranged with the cladding member 2 of the non-circular structure.

[0024] Furthermore, the optical fiber in the cladding member 2 is a single-core 1 or multi-core 1 structure.

[0025] Furthermore, the multi-fiber cores 1 are evenly distributed in the cladding member 2 and are in contact with each other.

[0026] The non-circular structure includes a polygonal shape for reducing the gap between the cladding 2 and the core 1 .

[0027] It should be noted that: the multiple fiber cores 1 are synchronously tightened and positioned by the polygonal non-circular inner wall, which improves the contact stability between the fiber cores 1, reduces the gaps between the multiple fiber cores 1, and reduces the waste of space.

[0028] Embodiment 2

[0029] like Figure 2 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0030] As an improvement, the non-circular structure also includes a flower shape or an irregular shape for arranging the multiple fiber cores 1 .

[0031] It should be noted that by configuring the non-circular structure to be a flower shape or an irregular shape, the flower-shaped or irregular-shaped cladding member 2 can enhance the mechanical stability of the optical fiber bundle through the concave-convex structure of the inner surface.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
