Abstract

(57) [Abstract] [Purpose] When mounting the optical fiber fusion splicing part on the device after reinforcement, there is a problem that a vast space is required between the drum around which the fiber is wound, the optical component, and the reinforcement substrate. However, we will solve this problem and reduce the mounting space. [Structure] A curved glass-ceramic plate 1 is provided on a hot-melt film 2 that melts when heated to form an adhesive. The optical fiber element wire 5 that has been fusion-bonded is set on the hot melt film 9 attached to the drum 3, the optical fiber element wire 5 is sandwiched between the glass ceramic plates 1 of the reinforcing substrate, and the glass ceramic plate 1 is pressed. While heating, the hot melt films 2 and 9 are melted and the optical fiber element wire 5 is adhesively fixed between the drum 3 and the glass ceramic plate 1. When mounting the reinforced optical fiber in the apparatus, the reinforcing substrate can be attached to the drum, so that the mounting space can be narrowed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an optical fiber fusion splicing, and particularly to a reinforcing substrate suitable for reinforcing an optical fiber fusion splicing portion.

[0002]

[Prior Art]

 In the conventional optical fiber fusion splicing part reinforcing substrate, as shown in FIGS. 4A and 4B, a hot melt film 2 is attached to one surface of a glass ceramic plate 7.

The reinforcing substrate is provided with an optical fiber 4 wound around a drum 3 as shown in FIG. 6 and an optical fiber provided by another optical component 10 as shown in FIGS. 5 (a) and 5 (b). The optical fiber 8 fused and spliced with 8 is set in a sandwich shape between the glass ceramic plates 7 and heated while pressing the glass ceramic plates 7 to melt the hot melt film 2 as shown in FIG. The optical fibers 4 and 8 set between the glass ceramic plates 7 are adhesively fixed to reinforce the optical fiber fusion splicing portion.

[Problems to be solved by the device]

 However, in this conventional optical fiber fusion splicing part reinforcing substrate, when the optical fiber having the splicing splicing part reinforced is accommodated in the extra length container, the space thereof is larger than the drum size as shown in FIG. However, the size of the optical component and the size of the reinforcing substrate are required to be combined, and there is a drawback that a vast space is required.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, an object of the present invention is to provide a novel optical fiber fusion splicing portion capable of solving the above-mentioned drawbacks inherent in the conventional technology. It is to provide a reinforcing substrate.

[0006]

In order to achieve the above object, a curved type optical fiber fusion splicing part reinforcing substrate according to the present invention has a hot melt film disposed inside a curved glass ceramic plate. It is composed of

【Example】

 A preferred embodiment of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention. 2 is a perspective view showing a state where an optical fiber is sandwiched between a reinforcing substrate according to the present invention and a drum, and FIG. 3 shows a state after optical fiber reinforcement is performed using the reinforcing substrate according to the present invention. It is a perspective view.

With reference to FIGS. 1 to 3, a hot-melt film 2 that serves as an adhesive when melted when heated is provided inside a curved glass-ceramic plate 1. As shown in FIG. 2, the optical fiber 4 wound around the drum 3 and the optical fiber 8 of the other optical component 10 are fusion-spliced together, and the optical fiber element wire 5 is attached to the drum 3. It is set so as to be located on the melt film 9. The glass ceramic plate 1 is set so that the hot melt film 9 attached to the drum 3 and the hot melt film 2 attached to the curved glass ceramic plate 1 which is the reinforcing substrate are aligned with each other, and the glass ceramic reinforcement is performed. By heating the substrate 1 while pressing it, the hot melt films 2 and 9 are melted as shown in FIG. 3, and the optical fibers 4 and 8 are bonded and fixed between the drum 3 and the glass ceramic plate 1 of the reinforcing substrate. R.

When the reinforced optical fibers 4 and 8 are accommodated in the extra length container, the size of the drum 3 and the optical component 10 are increased because the glass ceramic 1 is attached to the drum 3 as shown in FIG. Only the required storage space.

[0011]

[Effect of the device]

 As described above, according to the present invention, the hot melt film is attached to the drum, and the glass ceramic plate is curved at the value of the diameter of the drum. It can be reinforced on the circumference, and the effect is that the fiber storage space can be reduced.
