The utility model provides a single mode fiber tail optical fiber, the internal thread lantern ring structure at its both ends is not only easily discerned the optic fibre tail optical fiber and is corresponded the joint, and the outside glass of optic fibre manages to appear damaging and restores in real time easily fast moreover.
Description
Technical field
The utility model relates to a kind of single-mode optical fiber pigtail.
Background technology
Optical fiber pigtail: be forever attached on element, is convenient to one section of short fiber of this element and another Fiber connection.Optical fiber buttock line refers to the joint of a similar half wire jumper for connecting fiber and fiber coupler, and it comprises a jumper terminal and one section of optical fiber.Optical fiber pigtail only has one to be active joint, tail optical fiber is again pigtail line, one end is only had to have connector, and the other end is the broken end of an optical cable fibre core, be connected with other optical cable fibre cores by welding, often appear in optical fiber terminal box, for connecting optical cable and fiber optical transceiver (between also use coupling mechanism, wire jumper etc.).
The optical fiber pigtail of prior art is in fiber box, and a large amount of tail optical fibers forms multiple fibre bundle, very numerous and diverse, is not easy to arrange.Special in fault detect, find the time and efforts that corresponding two ends need at substantial, reduce work efficiency.In addition, the glass tube of outer fiber is very fragile, excessive tensile or bending all easily cause damaging even rupture, need a kind of simple and effective real-time repair mode.
Utility model content
The purpose of this utility model is the problem overcoming prior art, provides a kind of single-mode optical fiber pigtail, is not only easy to identify corresponding joints, and easily reparation appears damaging in outer fiber glass tube.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Single-mode optical fiber pigtail, comprise optical fiber and the jumper terminal and the joints of optical fibre that are arranged on optical fiber head and the tail two ends, described optical fiber head and the tail two ends place is all provided with thread segment, on described thread segment, cover is connected with the internal thread collar, inner ring screw thread and the thread segment of the described internal thread collar match, the described internal thread collar is that glass material is made, and its outer surface has fluorescence coating.The quantity of the internal thread collar and the color of outer surface fluorescence coating can play marked effect, and fluorescence coating also facilitates for the marked effect under dark surrounds.
Inner ring screw thread and the thread segment of the described internal thread collar match, the internal diameter and the fibre diameter that are the internal thread collar match, when fracture or other faults appear in outer fiber glass tube section, can the internal thread collar be screwed onto herein, inside is clicked and entered double strength glass glue again and is fixed, and can play repairing effect rapidly.
Wherein, the glass material that adopts of the described internal thread collar is identical with outer fiber glass tube.Be adhesively fixed like this after repairing, do not affect the Signal transmissions of inner single-mode fiber fiber.
Wherein, the thread segment length at described optical fiber head and the tail two ends is identical, symmetrical.
Wherein, the width of the described internal thread collar is 1/5 ~ 1/6 of thread segment length.Such thread segment can be equipped with one or more internal thread collar.
Compared with prior art, the beneficial effects of the utility model: the utility model provides a kind of single-mode optical fiber pigtail, the inner screw sheath ring structure at its two ends is not only easy to identify optical fiber pigtail corresponding joints, and outer fiber glass tube occurs that damage is easily repaired real-time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1, optical fiber; 2, the internal thread collar; 3, jumper terminal; 4, the joints of optical fibre; 11, thread segment.

Inner ring screw thread and the thread segment 11 of the described internal thread collar 2 match, the internal diameter and optical fiber 1 diameter that are the internal thread collar 2 match, when fracture or other faults appear in optical fiber 1 outer glass pipe section, can the internal thread collar 2 be screwed onto herein, inside is clicked and entered double strength glass glue again and is fixed, and can play repairing effect rapidly.
Wherein, the glass material that adopts of the described internal thread collar 2 is identical with optical fiber 1 outer glass tube material.Be adhesively fixed like this after repairing, do not affect the Signal transmissions of inner single-mode fiber fiber.
Wherein, thread segment 11 length at described optical fiber 1 head and the tail two ends is identical, symmetrical.
Wherein, the width of the described internal thread collar 2 is 1/5 ~ 1/6 of thread segment 11 length.Such thread segment can be equipped with one or more internal thread collar 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
