Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Prior art and its problems will be described before proceeding with the description of the embodiments of the present invention:
at present, optical fibers are welded, namely, coating layers of to-be-welded parts of the two optical fibers are removed, only fiber cores of the optical fibers are left, end faces of the fiber cores of the optical fibers are cut flat, then a hot melting pipe is sleeved on the optical fibers and put on a hot melting machine to be welded, the hot melting pipe and the to-be-welded parts of the two optical fibers form a whole after being welded, and the hot melting pipe is tightly attached to the to-be-welded parts of the two optical fibers to form a protective layer.
However, air is present between the fusion tube and the core of the optical fiber. When welding, bubbles are easily formed in the hot-melt tube due to uneven heating of the whole hot-melt tube. While the hot melt tube in the bubble-forming cavity region is not integral with the core of the fiber. The core protection of the fusion tube for the cavity region is limited. And the to-be-welded part of the optical fiber after hot melting is only protected by the hot melting pipe, the stability of the to-be-welded part of the optical fiber is poor, and after the optical core of the to-be-welded part is subjected to the action of external force, the to-be-welded part of the optical fiber is more easily broken and broken compared with other parts of the optical fiber, such as bending and hard extrusion, or strong impact vibration is likely to cause the damage of the to-be-welded part of the optical fiber.
Therefore, the protection of the fused fiber core is limited and the stability is insufficient after the optical fibers are fused by the prior art.
In view of the above, an embodiment of the present invention provides an optical fiber fusion method. Fig. 1 shows a flowchart of an optical fiber fusion method according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step 11: and cutting the part to be welded of the first optical fiber to obtain the fiber core and the aramid yarn of the first optical fiber. Wherein the first optical fiber is an optical fiber with aramid yarn;
step 12: moving the hot melting pipe to the fiber core of the second optical fiber, the fiber core of the first optical fiber and the aramid yarn to form a component to be hot melted;
step 13: and welding the component to be fused.
It should be noted that, the aramid yarn is also called as an aramid yarn, and is a reinforcing element of an optical fiber, and generally, an indoor optical cable adopts the aramid yarn as a reinforcing element, such as a single-mode optical fiber. The portion to be fusion spliced of the first optical fiber means a portion where the first optical fiber and the second optical fiber are fusion spliced. The first optical fiber may be such that either one of the ends becomes a portion to be fusion-spliced with the second optical fiber, or when one end of the first optical fiber has been used as the other, the other end is used as the portion to be fusion-spliced. If the first optical fiber is a tail optical fiber, one end of the tail optical fiber is connected with a connector, and the other end of the tail optical fiber is used as a part to be welded with the second optical fiber.
Before the first optical fiber is cut, a coating layer of the to-be-welded part of the first optical fiber is cut off, and the fiber core and the aramid yarn of the to-be-treated first optical fiber are obtained. Cutting the fiber core of the first optical fiber to be treated to obtain the fiber core of the first optical fiber and the aramid yarn.
The second optical fiber may be an optical fiber with an aramid yarn or an optical fiber without an aramid yarn. The core of the second optical fiber can be obtained by removing the coating layer of the part to be welded of the second optical fiber and cutting the end, far away from the second optical fiber, of the core of the second optical fiber into a plane. Further, when the second optical fiber is an optical fiber without aramid yarn, the end face of the core of the second optical fiber may be flattened. And when the second optical fiber is an optical fiber with aramid yarn, cutting off the aramid yarn of the second optical fiber and cutting off the end face of the fiber core of the second optical fiber.
In some embodiments, the first optical fiber is cleaved, such as by a cleaving machine, except that the end face of the core of the first optical fiber is flattened. It is also desirable to cut the core of the first optical fiber to a length of the core of the first optical fiber that is less than the length of the aramid yarn, as shown in fig. 2. Illustratively, the first optical fiber has a core length of 10-20mm and the aramid yarn has a length of 30-40mm.
In order to protect both the core of the first optical fiber and the core of the second optical fiber from the aramid yarn, it is also necessary to make the length of the aramid yarn of the first optical fiber greater than the sum of the lengths of the cores of the first optical fiber and the second optical fiber. The length of the core of the second optical fiber may be 10-20mm, such as when the length of the core of the first optical fiber is 10-20mm and the length of the aramid yarn is 30-40mm.
In addition, after cleaving, the cores of the first and second optical fibers need to be cleaned, such as by wiping the cores of the first and second optical fibers with alcohol.
In some embodiments, it may also be desirable to align the cores of the first and second fibers prior to step 12. When the fiber core of the first optical fiber and the fiber core of the second optical fiber are aligned by using the fusion splicer, the first optical fiber and the second optical fiber are respectively clamped by using the clamp, and then the first optical fiber and the second optical fiber are fixed at the corresponding positions of the fusion splicer together by connecting the clamp, and the fusion splicer performs first fusion so as to align the fiber core of the first optical fiber and the fiber core of the second optical fiber.
It should be noted that, in step 12, the hot-melt tube may be threaded into the second optical fiber before the coating layer of the first optical fiber is removed. After penetrating into the second optical fiber, the second optical fiber is positioned on one side of the second optical fiber far away from the part to be welded. After the fiber cores of the first optical fiber and the second optical fiber are aligned, the hot melt pipe on the first optical fiber is only required to be moved to the fiber cores of the second optical fiber, the fiber cores of the first optical fiber and the aramid yarn. Specifically, in step 12, the hot-melt tube may be moved toward the to-be-welded portion of the second optical fiber until the hot-melt tube is partially sleeved on the core and the aramid yarn of the first optical fiber and another portion is sleeved on the core and the aramid yarn of the second optical fiber.
In some embodiments, when the length of the aramid yarn of the first optical fiber is greater than the sum of the lengths of the fiber cores of the first optical fiber and the second optical fiber, the hot-melt tube may be moved toward the to-be-welded portion of the second optical fiber until the hot-melt tube is partially sleeved on the fiber core of the first optical fiber, the other part of the hot-melt tube is sleeved on the fiber core of the second optical fiber, the aramid yarn is partially positioned outside the hot-melt tube, the aramid yarn positioned outside the hot-melt tube is used as a stress point, and the position of the aramid yarn in the hot-melt tube is adjusted to obtain the to-be-hot-melted assembly. If the part of the aramid yarn outside the hot melting pipe is clamped by the hand or the clamp, the aramid yarn is moved along the outer walls of the fiber cores of the first optical fiber and the second optical fiber, and the positions of the aramid yarn are adjusted so that the aramid yarn can uniformly wrap the fiber cores of the first optical fiber and the second optical fiber, and an effective protection effect is achieved on the fiber cores of the first optical fiber and the second optical fiber.
In some embodiments, when the components to be fused are fused, the components to be fused are moved to a heating platform of a fusion splicer to be heated and fused, so as to obtain the fused optical fibers.
According to the embodiment of the invention, the aramid yarn is filled between the hot melting pipe and the fiber core of the optical fiber, so that bubbles are not easy to form in hot melting of the hot melting pipe, after the hot melting pipe is welded, the stress toughness and strength of the fiber core of the first optical fiber and the fiber core of the first optical fiber are enhanced by the aramid yarn, the formation of the welding part of the optical fiber is effectively protected, the protection force is stronger, and meanwhile, the stability of the welding part of the welded optical fiber is improved.
Fig. 3 shows an optical fiber fusion splicing method according to another embodiment of the present invention. As shown in fig. 3, the method comprises the steps of:
step 31: cutting a part to be welded of a first optical fiber and a part to be welded of a second optical fiber to obtain a fiber core of the first optical fiber and a fiber core of the second optical fiber;
step 32: moving a hot melting pipe to the fiber cores of the first optical fiber and the second optical fiber, and filling aramid yarns into the hot melting pipe to form a component to be hot melted;
step 33: and welding the component to be fused.
The first optical fiber and the second optical fiber may be optical fibers with or without aramid yarns. When the first optical fiber and the second optical fiber are optical fibers without aramid yarns, the end faces of the cores of the first optical fiber and the cores of the second optical fiber may be flattened in step 31. When the first optical fiber and the second optical fiber are optical fibers with aramid yarns, the aramid yarns of the second optical fiber and the second optical fiber need to be cut off in step 31.
In some embodiments, in step 31, the fusion pipe may be threaded into the first optical fiber and the second optical fiber before removing the coating layer of the second optical fiber or the second optical fiber. And after penetrating into the second optical fiber or the second optical fiber, the optical fiber is positioned on one side of the second optical fiber or the second optical fiber away from the part to be welded. After the fiber cores of the first optical fiber and the second optical fiber are aligned, the hot melt pipe on the first optical fiber is only required to be moved to the fiber cores of the second optical fiber and the first optical fiber. Further, when the aramid yarn is filled in the hot melting pipe, one end of the aramid yarn can be penetrated from one end of the hot melting pipe and penetrated from the other end of the hot melting pipe by means of a threading tool. If the threading tool can be a sewing needle, one or more pieces of aramid yarn are hung on the sewing needle through needle holes of the sewing needle, one end of the aramid yarn penetrates from one end of the hot melting pipe along with the sewing needle, penetrates from the other end of the hot melting pipe, and then the aramid yarn is filled in the hot melting pipe. In addition, after the aramid yarn is filled in the hot melting pipe, the part of the aramid yarn positioned outside the hot melting pipe can be clamped by a hand or a clamp, the aramid yarn is moved along the outer walls of the fiber cores of the first optical fiber and the second optical fiber, and the positions of the aramid yarn are adjusted so that the aramid yarn can uniformly wrap the fiber cores of the first optical fiber and the second optical fiber, and an effective protection effect is achieved on the fiber cores of the first optical fiber and the second optical fiber.
According to the embodiment of the invention, the aramid yarn is filled between the hot melting pipe and the fiber core of the optical fiber, so that bubbles are not easy to form in hot melting of the hot melting pipe, after the hot melting pipe is welded, the stress toughness and strength of the fiber core of the first optical fiber and the fiber core of the first optical fiber are enhanced by the aramid yarn, the formation of the welding part of the optical fiber is effectively protected, the protection force is stronger, and meanwhile, the stability of the welding part of the welded optical fiber is improved.
An embodiment of the present invention provides an optical fiber that can be obtained by the optical fiber fusion splicing method provided in the above embodiment. As shown in fig. 4, which shows a cross-sectional view of the optical fiber, the optical fiber 2 includes a fusion splice site, wherein the fusion splice site includes a core 21, an aramid yarn 22, and a hot-melt tube 23. The aramid yarn 22 is positioned in the hot melt tube 23, and the aramid yarn 22 wraps the fiber core 21. Through pack aramid yarn between the fiber core of hot melt pipe and optic fibre for the hot melt pipe is difficult to form the bubble when the hot melt, and after the butt fusion, strengthen the atress toughness and the intensity to the fiber core of first optic fibre and the fiber core of first optic fibre through aramid yarn, the formation of the butt fusion position to optic fibre is more effectual protection, and the protection dynamics is stronger, has improved the stability of the butt fusion position of optic fibre after the butt fusion simultaneously.
