Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical communication technology, and in particular to a colored optical fiber and its optical cable. Background Technology
[0002] Multi-core tight-buffered optical fiber cables generally use color and color rings to distinguish optical fibers. For tight-buffered fibers with colored tight-buffered layers, it is necessary to frequently replace optical fibers and color tight-buffered materials during production. Taking a set of 12-color + 12-color ring optical fibers as an example, producing a set of tight-buffered optical fibers requires at least 12 shutdowns for material replacement, fiber threading and debugging, and 12 rewinding and color ringing.
[0003] For multi-core optical cables with transparent tight-buffered fibers, the tight buffer is often made of transparent nylon, TPU, or PVC. Different colored fibers and color-ringed fibers are used to distinguish the fibers. Colored fibers have a standard 12 colors, and color-ringed fibers can be further divided into single-color rings, dual-color rings, and tri-color rings. Different colored fibers and color-ringed fibers are separated into different reels during the coloring process, but the tight-buffering process requires frequent machine stops for fiber and reel replacements. For example, producing one set of 12-color + 12-ringed fibers requires 24 machine stops for fiber threading and adjustment. Each fiber replacement and adjustment results in waste of tight-buffering materials, fiber, and manpower / machine time. Utility Model Content
[0004] In view of this, one of the objectives of this utility model is to provide a colored optical fiber to solve the technical problem in the prior art that when producing a set of tight-buffered optical fibers or optical cables, it is necessary to replace different colored optical fibers, which leads to the waste of re-disassembling and reassembling molds and threading and adjusting the molds.
[0005] The second objective of this invention is to provide an optical cable containing colored optical fibers.
[0006] To achieve one of the above objectives, this utility model provides a colored optical fiber, including an optical fiber body having a preset length, the optical fiber body being covered with a colored layer, the colored layer being continuously arranged and single, and adjacent colored layers using different color layers.
[0007] Optionally, the lengths of the color layers may be equal or unequal, and the lengths are determined according to the length of the reel for the subsequent tight-buffered optical fibers and the number of cabling. The length of the optical fiber body with N color layers is L = L1 + L2 + L3 + ... + LN, where N is the color of the color layer.
[0008] Optionally, the surface of the color layer is provided with a coating layer.
[0009] Optionally, the covering layer may be a transparent PVC, PA, or TPU tight-fitting layer, a transparent PVC, PA, or TPU semi-tight-fitting layer, or a transparent PVC, PA, or TPU loose-fitting layer.
[0010] Optionally, the covering layer is a PVC or LSZH tight-fitting layer in a color corresponding to the coloring layer, a PVC or LSZH semi-tight-fitting layer in a color corresponding to the coloring layer, or a PVC or LSZH loose-fitting layer in a color corresponding to the coloring layer.
[0011] Optionally, a cutting dividing line is set between two adjacent coloring layers on the optical fiber body, and the lengths of the optical fiber body are LN, LN-1...L2, L1, where N is the color of the coloring layer.
[0012] Optionally, the covering layer is a PVC or LSZH tight-fitting layer of M different colors, a PVC or LSZH semi-tight-fitting layer of M different colors, or a PVC or LSZH loose-fitting layer of M different colors.
[0013] Optionally, the color of the coloring layer is the same as and / or different from the color of the covering layer.
[0014] Optionally, a cutting dividing line is set between two adjacent coloring layers on the optical fiber body, and the length of the optical fiber body is LM*N, LM*N-1...L2, L1, where M*N is the color combination of the coloring layer and the cladding layer.
[0015] To achieve the second objective mentioned above, this utility model provides an optical cable, including any of the colored optical fibers described above.
[0016] The colored optical fiber provided by this utility model has the following technical effects:
[0017] This type of colored optical fiber consists of an optical fiber body with a preset length. The optical fiber body is covered with a colored layer, which is continuously arranged and single. Different color layers are used between two adjacent colored layers. The colored layer can be a single continuous color or a color ring. Since the optical fiber body of this invention can form colored optical fibers of multiple colors or color ring optical fibers of multiple colors, the optical fiber body can be made into a reel of optical fiber. During the production of tight-buffered optical fiber, it can be automatically reeled according to color. This greatly avoids the waste caused by color changing during the coloring and tight-buffering processes. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Based on the deficiencies described in the existing technology, the following section, in conjunction with specific appendices, discusses... Figure 1-3 The colored optical fiber of this utility model will be described in detail.
[0026] like Figure 1-3 The diagram shown is a structural schematic of a preferred embodiment of the colored optical fiber of the present invention. The colored optical fiber includes an optical fiber body 1 with a preset length, and a colored layer 2 is covered on the optical fiber body 1. The colored layer 2 is continuously arranged and single, and different color layers are used between two adjacent colored layers 2. The colored layer 2 of the present invention can be a single continuous color or a single continuous color ring. The single continuous color can exist alone or together with a single continuous color ring, and the same applies to the single continuous color ring.
[0027] The lengths of the coloring layers 2 are equal or unequal, and the lengths are determined by the length of the trays for the subsequent tight-buffered optical fibers and the number of cables. The lengths of the optical fibers with N colors are L = L1 + L2 + L3 + ... + LN.
[0028] In detail, the colors in this embodiment can be blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, cyan, etc., and the color wheel can be a single color wheel, a two-color wheel, a three-color wheel, etc.
[0029] For example, such as Figure 1 and Figure 3 The diagram shows a structural schematic of an optical fiber, which includes a blue optical fiber segment, an orange optical fiber segment, and a green optical fiber segment, all of which are of equal length.
[0030] In a preferred embodiment, the surface of the coloring layer 2 is provided with a coating layer 3, such as... Figure 2 As shown.
[0031] In one scenario, the cladding layer 3 is a transparent PVC, PA, or TPU tight-buffered layer, a transparent PVC, PA, or TPU semi-tight-buffered layer, or a transparent PVC, PA, or TPU loose-buffered layer. A cutting dividing line is set between two adjacent colored layers 2 on the optical fiber body, and the lengths of the optical fiber body sections are sequentially LN, LN-1…L2, L1, where N is the color of the colored layer 2.
[0032] The outer diameter of the tight-fitting layer, the semi-tight-fitting layer, and the loose-fitting layer ranges from 0.35 mm to 0.95 mm, preferably 0.6 mm.
[0033] The optical fiber body 1 of this embodiment can avoid the waste caused by frequently changing optical fibers of different colors, such as disassembling and reassembling the mold, and threading and adjusting the mold.
[0034] Another scenario involves the cladding layer 3 being a PVC or LSZH tight-buffered layer of the same color as the coloring layer 2, a PVC or LSZH semi-tight-buffered layer of the same color as the coloring layer 2, or a PVC or LSZH loose-buffered layer of the same color as the coloring layer 2. A cutting dividing line is set between two adjacent coloring layers 2 on the fiber body, and the lengths of the fiber body sections are sequentially LN, LN-1…L2, L1, where N is the color of the coloring layer 2.
[0035] The outer diameter of the tight-fitting layer, the semi-tight-fitting layer, and the loose-fitting layer ranges from 0.35 mm to 0.95 mm, preferably 0.6 mm.
[0036] In this embodiment, the inner and outer colors of the optical fiber body 1 are consistent, which makes it more easily identifiable and avoids the waste caused by frequently changing different colored optical fibers or different colored coating materials, which would require disassembling and reassembling the mold, threading and adjusting the mold, and changing colors.
[0037] Another scenario is that the cladding layer 3 is a PVC or LSZH tight-buffered layer of M different colors, a PVC or LSZH semi-tight-buffered layer of M different colors, or a PVC or LSZH loose-buffered layer of M different colors. The color of the coloring layer 2 is the same as and / or different from the color of the cladding layer 3. A cutting dividing line is set between two adjacent coloring layers 2 on the optical fiber body, and the lengths of the optical fiber body reels are successively LM*N, LM*N-1...L2, L1, where M*N is the color combination of coloring layer 2 and cladding layer 3.
[0038] The outer diameter of the tight-fitting layer, the semi-tight-fitting layer, and the loose-fitting layer ranges from 0.35 mm to 0.95 mm, preferably 0.6 mm.
[0039] The optical fiber body 1 in this embodiment provides more optical fiber port color combination identification schemes for ultra-high core count coated optical fibers. This avoids the waste caused by frequently changing different colored fibers or different colored coating materials, which would require disassembling and reassembling the mold, threading and adjusting the mold, and changing colors. At the same time, it avoids the process of creating color rings for the same coating layer color.
[0040] As a preferred implementation, indoor mini optical cables or loose tubes produced using multi-reel continuously colored optical fibers can produce multiple reels of the same core number but with different color sequences and identical appearances in a single production run by controlling the color sequence of each fiber reel. This avoids the waste caused by replacing multiple fiber reels. The mini optical cables or loose tubes themselves do not require color or serial number differentiation; each sub-unit is identified through the individual optical fibers, ensuring good confidentiality.
[0041] For the optical fiber body 1 in this embodiment, a continuous optical fiber coloring device is used for coloring. The continuous optical fiber coloring device mainly consists of a mechanical transmission system, an ink storage system, a color ring system, a color management system, and an operating system.
[0042] The mechanical transmission system controls the transmission of the optical fiber, the color ring system rings the optical fiber before coloring, the ink storage system stores inks of various colors (up to 12 colors are possible), the color management system controls the mixing and quantitative output of the inks, and the operating system regulates and monitors the entire system. By setting the order and length of several colors through the operating system, when the Nth color has been produced to a set length LN, the operating system sends instructions to the color management system and the color ring system to automatically switch to the next color. This enables continuous coloring of different colors or color rings onto a single reel of optical fiber, with the length of the fiber containing N colors being L = L1 + L2 + L3 + ... + LN.
[0043] The colored optical fiber of this utility model will be described in detail below with reference to specific embodiments.
[0044] Example 1
[0045] A spool of optical fiber has several colors or color rings on its surface. The colors can be blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, cyan, etc. The color rings can be single-color rings, two-color rings, three-color rings, etc. Each color or color ring is continuous and singular. Different colors are connected in a set order. The length of the optical fiber for each color or color ring may be equal or unequal. The length of the optical fiber for each color is determined by the length of the spool for the subsequent tight-buffered optical fiber and the number of cables. The length of the optical fiber with N colors is L = L1 + L2 + L3 + ... + LN.
[0046] Example 2
[0047] A transparent PVC, PA, or TPU tight-buffered, semi-tight-buffered, or loose-buffered layer is coated onto the surface of a continuously colored optical fiber. The outer diameter of the coating layer is 0.35mm to 0.95mm. The coated optical fiber is cut and reeled at the boundary between two adjacent colors. The reel lengths of the coated optical fiber are LN, LN-1...L2, L1, representing the N colors of the optical fiber.
[0048] Example 3
[0049] A tight-buffered, semi-tight-buffered, or loose-buffered layer of PVC or LSZH of the corresponding color is coated onto the surface of a continuously colored optical fiber. The outer diameter of the coating layer is 0.35–0.95 mm. The color of the optical fiber is the same as that of the coating layer. The coated optical fiber is cut and reeled at the boundary between two adjacent colors. The reel lengths of the coated optical fiber are LN, LN-1…L2, L1, representing the N colors of the optical fiber and the coating layer, respectively.
[0050] Example 4
[0051] A tight-buffered, semi-tight-buffered, or loose-buffered layer of M different colored PVC or LSZH fibers is coated onto the surface of a continuously colored optical fiber. The outer diameter of the coating layer is 0.35–0.95 mm. The fiber color may be the same as or different from the coating layer color. The coated fiber is cut and reeled at the boundary between two adjacent colors. The reel lengths of the coated fiber are successively LM*N, LM*N-1…L2, L1, representing the color combinations of M*N fibers * coating layers, providing more fiber port color combination identification schemes for ultra-high core count coated fibers. This avoids the waste caused by frequently changing different colored fibers and coating materials, which requires disassembling and reassembling molds, threading and adjusting the mold, and changing colors. It also avoids the process of creating color rings for the same coating layer color.
[0052] Example 5
[0053] Indoor mini optical cables or loose tubes produced using multi-reel continuously colored optical fibers can be manufactured in a single batch by controlling the color sequence of each reel. These cables or tubes have the same core count but different color sequences, resulting in identical appearances and avoiding the waste caused by replacing multiple reels of fiber. Furthermore, the mini optical cables or loose tubes themselves do not require color or serial number differentiation; each sub-unit is identified directly from the fiber itself, ensuring good confidentiality.
