DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical fiber used for connecting an end face of a bare fiber from which an optical fiber coating has been removed by using a splicer such as an optical fiber fusion machine. The present invention relates to a connection workbench.

[0002]

2. Description of the Related Art In general, when optical fibers are connected to each other, the bare fiber is exposed by removing the coating by a predetermined length (for example, 25 mm) using a dedicated coating removing tool such as a hot jacket remover. After cutting and finishing the ends of the bare fibers, the bare fibers are connected to each other. As a connection method, a method of inserting the tip of the bare fiber into a member called a sleeve from both sides to butt the bare fibers and mechanically connect them, or a method of fusing by melting the tip of the butted bare fiber. is there.

FIG. 6 is a side view showing a conventional workbench for an optical fiber splicer, and FIG. 7 is a plan perspective view of a main part, which is described, for example, in Japanese Patent Application Laid-Open No. 8-184725. In the figure, 56 is a base fixed on a flat work table 80, 51 is a center table, 71 and 72 are optical fibers, 75
Is a slide table on which the center table is placed, and 76 is a slide table 75
Adjustment screw for adjusting the front and rear, 52 is a fixed table, 53 is a movable table, 57 and 62 are a fixed table 52 and a movable table 53
Are the holders, 54 and 55 are holders, 20 is a connecting machine, 20a is a sleeve, and 20b is a guide groove.

[0004] In the mechanical connection method, the bare fiber of the optical fibers 71 and 72 is inserted from the guide grooves 57 and 62 into the sleeve 20a along the guide groove 20b. , 72 bare fibers are set in the connecting machine 20.

FIG. 8 is a plan view showing a main part of the optical fiber fusion splicer. In the case of the fusion splicing method, similarly to the above-described mechanical connection method, the V is formed on the fixed base 52 formed in the optical fiber fusion splicer.
When the bare fibers 73 and 74 are abutted along the guide grooves 52a and 52b of the shape, the movable table 53 is set up and down and left and right, and the tip of the bare fibers 73 and 74 is melted by the arc generated by the discharge electrode 60. Press and connect at the same time.

[0006]

The conventional optical fiber splicer or the optical fiber fusion splicer has been installed on the flat mounting table as described above. In order to butt and connect the bare fibers, the ends must be carefully set from both sides with the ends along the guide grooves so as not to damage the bare fiber portion. However, with this set, the worker is in a posture of peeping from above, tired by long hours of work, and the set part is difficult to see, causing damage to the bare fiber or poor connection, resulting in a low yield. There was a problem of lowering.

Further, in the above-mentioned conventional optical fiber connection work table, in order to avoid damage to the optical fiber coating, it is necessary to route the optical fiber so as not to come into contact with the corners or protrusions of the fusion splicer or the splicer. In addition, since the distance between the fusion splicer or the splicer and the mounting table surface is large, it is necessary to increase the extra length of the optical fiber.For example, in order to store this extra optical fiber in a repeater for optical communication. Space was required, and there was a problem that it could not be made compact.

An object of the present invention is to solve the above-mentioned problems and to improve the yield by improving the workability in connecting bare fibers with the optical fiber coating removed.

Another object of the present invention is to reduce the length of the optical fiber, eliminate unnecessary space, and reduce the size of the repeater.
