Abstract

PURPOSE:To prevent the formation of the bridging of a resin and the generation of nonuniformity of resin coating films without allowing respective fibers to approach each other by putting the exposed parts of respective fibers resin into the resin ball of a thin film forming means, then moving the thin film forming means in the axial center direction of the respective fibers and forming the resin films on the exposed parts of the respective fibers. CONSTITUTION:The UV resin is dropped into a slot 6 of a thin film forming plate 2 as the thin film forming means to hold the UV resin ball 3 on the thin film forming plate. The thin film forming plate 2 is thereafter moved toward the optical fibers (f) (arrow direction A) to insert the optical fibers (f) into the slot 6 and to position the fibers in the middle of the UV resin ball 3. The thin film forming plate 2 is thereafter lowered (arrow B) down to the position of a coating S in parallel with the optical fibers (f). Then, the part upper than the coating S is formed with the UV resin films on the fibers (f) over the length (l). The resin coating films having a uniform shape of the resin pool are formed on the surfaces of the respective fibers of the tape fiber in this way.

[Industrial Field of Application] This invention relates to a method for coating and connecting fibers for optical communication, and is suitable for connections in optical fibers that require sufficient tensile strength, such as undersea optical communication cables. It is effective when used to improve the tensile strength of the parts and to improve the connection accuracy of multifilamentary wires. [Prior Art and Problems of the Present Invention] Regarding optical communication cables, especially submarine optical communication cables, where large tensile forces are applied to the cables during the cable installation and service period, it is necessary to evaluate the strength reliability such as the tensile strength in advance. In order to confirm this, a reciting level bruch test is conducted. Particularly problematic in this proof test are connections in the middle of cables and connections within repeaters. Optical fiber connected using conventional connection method (125φμ@)
The tensile strength of the connection part is 0.4 to 0.18- or less. In order to improve the strength and reliability of optical fibers, it is essential to improve the tensile strength of this connection. It is a well-known fact that the tensile strength of optical fiber connections is significantly reduced by the presence of microscopic flaws on the surface of the connection. There is a high possibility that fine scratches on the surface of the connection portion will occur during coating removal work, connection end surface facing work, and fusion splicing work. As a method for minimizing the possibility of damaging the optical fiber surface during coating removal work and fusion splicing work, the optical fiber splicing method described in JP-A-63-184712 has been proposed. It is publicly known. The characteristics of this known optical fiber connection method are summarized as follows. (b) Prevention of scratches on the optical fiber surface caused by chemically removing the connecting end of the optical fiber using chemicals and mechanically removing the coating using a tool such as a stripper). B. Coating a thin UV light curing resin (hereinafter referred to as "rUV resin") on the exposed part other than the optical fiber splicing tip and curing it, and clamping this coated part with the clamp of the optical fiber fusion splicing device. It is something. By using the above method, the coating is mechanically removed using a tool such as a stripper, thereby preventing scratches on the surface of the optical fiber, and the exposed part of the optical fiber is directly clamped using the clamp, and the clamp is used to remove the coating. This prevents pressure and scratches on the surface of the optical fiber caused by pushing the fiber connection end in the axial direction. This conventional optical fiber connection method (hereinafter referred to as "prior art") sufficiently solves the problems and significantly improves the optical fiber connection technology. However, in recent years, optical fibers have been made into tapes in order to meet the demand for increased capacity of optical fiber cables. When applying the single-core method to this tape fiber, a bridge of coating resin 1, for example, UV resin, is often formed between adjacent optical fibers, and a method for tape fiber is desired.

(1) Regarding the invention claimed in claim 1 [Means taken to solve the problem] The means of the invention claimed in claim 1 taken to solve the above problem, that is, the solution means are the following elements (a) to (c). ). (a) Grasp the tip of the coated portion of the tape fiber with one end of the coating removed with a fiber clamp, and firmly hold the tip of the exposed portion of each fiber with a holder directly above the clamp. (b) Maintaining each fiber under a weak tension. (c) Move the resin thin film forming tool toward each fiber exposed portion, place the exposed portion of each fiber in the middle of the resin ball of the thin film forming tool, and then move the thin film forming tool in the axial direction of each fiber. Forming a resin coating on the exposed portion of each fiber. In addition, positioning the holder in element (A) above directly below the clamp is equivalent to element (A), and moving each fiber exposed part in element (C) toward the thin film forming tool is equivalent to positioning the holder directly below the clamp. , is equivalent to element (c). [The action co-holder is directly above the clamp and applies tension to each exposed fiber to make it straight, so each exposed fiber is positioned precisely in the middle of the resin bead of the thin film forming tool. , the positional relationship does not change even while the thin film forming tool is moving in the direction of each fiber axis. Also, both ends of the exposed portion of each fiber are held at a constant distance by a holder and a clamp, and tension is applied to all fibers. The entire length of each exposed fiber section is maintained at a constant mutual spacing at all times during resin coating. Therefore, the fibers do not come close to each other in the exposed portions of the fibers, and resin bridges are not formed between the fibers and the resin coating is not uniform. As described above, the above problem is sufficiently solved by the means of the invention set forth in claim 1. (2) Regarding the invention claimed in claim 2 [Means taken to solve the problem] The means of the invention claimed in claim 2 consists of elements (a) to (c) of the means of the invention claimed in claim 1 and the following: It is composed of the element (a'). (A') After the resin coating has hardened, the tip of the coating and the fiber tip are held with a clamp, and a fine incision is made with a cutter at a point beyond the tip of the resin coating, and the point where the fine incision is made between the tip of the resin coating and the above fine incision. 2 with 1 point from the other side
To create a fiber connection end face by pressing down on a point and folding it at the cut point. [Function] In the resin film coating process and curing process, the surface of the portion between the clamp that grips the tip of the coating and the holder that grips the tip of each exposed fiber portion is not damaged at all. Each fiber connection end face is generated by pressing two points, the tip of the resin coating and a point beyond this tip, and folding between the points, so that the fiber between this connection end face and the resin coating tip, That is, the part subjected to fusion splicing does not come into contact with anything during this connection end face production operation, so its surface is completely intact. Therefore, the strength of the fiber is completely prevented from being reduced due to minute scratches on the outer circumferential surface of the fiber tip used for fusion splicing. [Embodiments] N) The resin thin film molding tool of element (c) of the means for solving the invention as set forth in claim 1 is a thin film molding plate with slots. Forming a slot through which each fiber passes through the plate, dropping resin onto the slot to hold the resin, and supporting the resin [because the fi product is large, the resin is placed on the plate A resin pool with a gentle, low convex curved surface is formed on both the front and back surfaces of the resin. Therefore, the shape of the resin pool becomes close to the ideal shape, which forms a uniform resin coating on the surface of each fiber of the tape fiber. (II) Regarding the exposed portion of each fiber in element (a) of the solution of the invention of claim 1, a part of the coating is left at the tip of the exposed portion. By leaving a portion of the coating on the tip of each fiber, the tips of each fiber are kept at regular intervals and the fibers are prevented from twiddling with respect to each other. It is possible to simply and easily hold the tips of the exposed portions of each fiber with a holder while maintaining a constant spacing between the fibers. (■) Fit the tip of each exposed fiber into the V-groove of the grooved aligner (■) on a vertical line passing through the clamp. By fitting the tip of the exposed portion of each fiber into the groove of the alignment tool and applying a weak tension to each fiber, the tip of the exposed portion of each fiber can be positioned simply, easily, and accurately. [Example] Hereinafter, an example in which the present invention is applied to a tape fiber connecting device will be described with reference to FIGS. 1, 2, and 3. One end of the tape fiber 'r is coated with the coating remainder S' at its tip.
, and remove the length L to expose the fiber f. In this example, there are four fibers f. This coating is removed using chemicals so as not to damage the fiber surface. For details, please refer to the above-mentioned publication, Japanese Patent Laid-Open No. 184712/1984. The coating S of each fiber is gripped by a normal fiber clamp 1, the upper end of the exposed part is fitted into the groove g of the alignment tool 5 one by one, and each fiber f is stretched straight by applying a weak tension. , the fiber f is gripped by a holder 4 which is located directly on the alignment tool 5 and whose positional relationship is fixed with respect to the clamp 1. As a result, each fiber f is held substantially parallel to each other and substantially perpendicular to each other with a constant spacing. UV resin is dripped into the slot 6 of the thin film forming plate 2 as a thin film forming tool to hold the U₂ resin balls 3 on the thin film forming plate. After that, move the thin film forming plate 2 toward the optical fiber f (
Movement in the direction of arrow A) Insert the optical fiber f into the slot 6 and position it in the middle of the UV resin ball 3. Thereafter, the thin film forming plate 2 is lowered parallel to the optical fiber f to the position of the coating S (arrow B). As a result, a UV resin coating is formed on the fiber f over a length Q above the coating is. When the pitch of the tape fibers is small, a UV resin bridge is formed between each fiber. Coating, the fiber spacing of the section is made larger than the fiber pitch. The thickness of the UV resin thin film formed on the outer surface of each fiber f depends on the viscosity of the UV resin and the descending speed of the thin film forming plate 2. Since it is actually difficult to adjust the viscosity of the UV resin in order to adjust the thickness of the film, it is better to adjust the descending speed of the thin film forming plate. The viscosity of UV resin at room temperature is 6500 (±100
0) When using CPS, F lowering speed is 0.07 mm/
sec, the coating outer diameter is 140 μm (fiber wire diameter 1
25μm) ±5μm. #The slower the descending speed of the film forming plate, the thicker the UV resin thin film becomes. Ultraviolet light (
UV) is irradiated to harden the resin coating. This ultraviolet irradiation is the same as that in the prior art. It is better to irradiate ultraviolet rays as soon as possible after the thin film is formed. As more time passes after the coating is formed, the uncured coating is deformed by gravity, impeding its thickness uniformity. After curing the UV resin coating, attach the holder 4 of the fiber f.
The part held by must be removed. This removal work will be explained with reference to FIG. Clamp the coating S and the exposed part of the optical fiber f 10.11
At a point slightly away from the tip of the portion C coated with UV resin, the cutter 12 makes a very fine incision on the lower surface of the fiber f, and the tip of the pressing member 13 with a cross-sectional opening is inserted. The distal end surface is brought into contact with the coated portion C and the exposed fiber portion, and pushed upward (arrow P) to bend the optical fiber f downward. Due to this bending, the optical fiber f is bent from the point where it is cut by the cutter 12, and a connection end surface is generated. This fractured surface becomes a mirror surface and is extremely smooth. This connection end face generation work is performed using a pressing member with a cross-sectional tip, so there is nothing to do with the part of the optical fiber that is to be fusion spliced (the part beyond the tip of the coated part C). can not touch. Therefore, there is no damage to the surface of this part, and the strength of the connection part is significantly improved. The pretreated tape fiber as described above is set in an optical fiber fusion splicing device, the portion coated with a UV resin film is held by a clamp, and the fiber is spliced by a conventionally well-known discharge fusion splicing method. [Effects] The problem to be solved by the present invention is a novel problem. Therefore, the fact that the above-mentioned problem has been solved, which is inherent in the prior art as described above, is itself a remarkable effect unique to the present invention. In addition, in the present invention, a part of the coating can be left at the tip of the tape fiber (because the connection end surface is generated immediately before the splicing process), so that the tips of a large number of core wires can be arranged at regular intervals. This makes it extremely easy to attach the tape fiber to the resin coating equipment.
Done quickly. Moreover, it has the great advantage of preventing the fibers from touching each other and scratching the surface.
