- FIG. 4 is an enlarged view of the vicinity of the optical fiber bent portion 15 (enlarged view of B portion in FIG. 3).
- the multi-core fiber 1 is bent along the optical fiber bent portion 15.
- light is introduced into the at least one core 5 of the multi-core fiber 1 by the light introduction unit 13 (light introduction process). Therefore, when the multicore fiber 1 is bent with a curvature greater than or equal to a predetermined curvature, light leaks to the outside according to the strain of the multicore fiber 1 (D in the figure) (light leakage step).
- the light detection unit 23 detects this leakage light (light detection step).

- a region below the neutral axis L (in the direction of the optical fiber bent portion 15) is a compression region due to bending deformation. That is, FIG. 5A is a diagram showing a state where the light introducing core 5a is located on the line G and located at a portion farthest from the neutral axis L (optical fiber bent portion 15). Therefore, the light introducing core 5a in this state is in a state where the largest tensile strain is generated.
- the light detection unit 23 detects the light intensity of the leaked light.
- FIG. 5B is a diagram showing a state in which the light introducing core 5a is located at a position shifted from the perpendicular G. That is, the multicore fiber 1 is slightly rotated from the state of FIG. 5A around the center of the cross section (H in the figure).
- the rotation with the central axis of the multicore fiber 1 as the rotation axis may be simply referred to as the rotation of the multicore fiber 1.
- the light introduction core 5a is slightly closer to the neutral axis L than in the state of FIG. For this reason, the distortion amount of the light introduction core 5a becomes small. As a result, the intensity of the leakage light D is lowered.
- the rotation direction of the multi-core fiber 1 can be more reliably detected by arranging the plurality of light detection units 23 at different positions in the circumferential direction of the multi-core fiber 1 and detecting leakage light from each direction. Can do.
- the light introducing core 5a is in the state of FIG. I understand that there is.
- the light intensity of leaking light becomes weak, it can be recognized that the multi-core fiber 1 is rotating.
- the rotation of the multi-core fiber 1 can be detected by detecting the leaked light from the cores. That is, it is desirable to use the outermost core as the light introducing core 5a for detecting such rotation.
- FIG. 6A to 6C are views showing the position of the light introducing core 5a and the inclination of the bobbin 12 in the cross section of the multi-core fiber 1.
- the bobbin control unit 25 controls the posture of the bobbin 12.

- the bobbin controller 25 tilts the rotation surface of the bobbin 12 in the direction opposite to the rotation direction of the multi-core fiber 1 (direction I in the drawing).
- the bobbin controller 25 inclines the rotation surface of the bobbin 12 in the direction opposite to the rotation direction of the multi-core fiber 1 (K direction in the figure). That is, the bobbin control unit 25 and the bobbin 12 function as an optical fiber rotating unit for rotating the multi-core fiber 1. In this manner, the optical fiber is rotated in the circumferential direction so that the amount of light leakage detected in the light detection step is substantially constant (optical fiber rotation step).
- each bobbin 12 is set according to the rotation angle of the multi-core fiber 1.
- the rotation angle may be calculated from the light intensity detected by the light detection unit 23, and the bobbin 12 may be inclined by an angle that cancels the rotation angle.
- the light intensity of the leaked light from the light detection unit 23 is a reference. You may incline until it becomes maximum intensity.
- each bobbin 12 is detected by the light detection unit 23 for each bobbin 12, and the posture is individually controlled by the bobbin control unit 25. Therefore, all the multi-core fibers 1 sent to the tape resin coating portion 21 can be controlled so as to face each other in the same direction.
- the multi-core fibers 1 are aligned, and the tape resin coating 9 is applied to the outer peripheral portion (taping process).
- the tape resin coating 9 is applied continuously or intermittently in the longitudinal direction of the tape core wire 10. In this way, by always controlling the specific core (light introduction core 5a) to be in a predetermined position in the cross section of the tape core wire 10, the core 5 is in the longitudinal direction.
- the arrangement can be made substantially constant.
- the tape core wire 10 can be easily aligned when connecting the tape core wire 10 to other fibers or elements.
- the position of the specific core 5 in the radial direction cross section of the multi-core fiber 1 sent to the tape resin coating part 21 can always be kept constant. Therefore, the specific core 5 can always be arranged at a fixed position when taped. For this reason, the arrangement of the cores 5 of all the multi-core fibers 1 can be made substantially constant over at least a predetermined length (preferably the entire length) of the tape core wire 10.
- the multi-core fiber 1 is taped while twisting so as to cancel the rotation. It becomes possible to.

- the guide 29 is a roller that guides the travel route of the multi-core fiber 1 so that the multi-core fiber 1 is brought into contact with the light introduction bending portion 27 in a predetermined range and bent.
- the multi-core fiber 1 passing through the light introducing bend 27 is irradiated with light by a light source disposed in the vicinity of the light introducing bend 27, light is introduced from the bend into the core inside the multi-core fiber 1. That is, light is introduced into the multi-core fiber 1 on the principle opposite to the leaked light in the optical fiber bent portion 15. A part of the light introduced into the multi-core fiber 1 is detected by the light detection unit 23 as leakage light in the optical fiber bending portion 15.
- the same effects as those of the first embodiment can be obtained.
- the light introduction part 13a since light cannot be introduced only into a specific core, light is introduced into a plurality of cores or almost all cores. However, even in this method, light can be efficiently introduced into the outermost core farthest from the neutral axis, and leakage light can be detected.
- Fig.8 (a) is a figure which shows the optical fiber tape core wire manufacturing apparatus 20b.

- the fiber rotating unit 31 is, for example, a roller.
- the multi-core fiber 1 is in contact with the fiber rotating part 31 in a predetermined range. Therefore, a predetermined frictional force is generated between the multicore fiber 1 and the fiber rotating part 31.
- the rotation control unit 24 controls the posture of the fiber rotation unit 31 based on the leaked light detected by the light detection unit 23. Specifically, the rotating surface of the fiber rotating unit 31 is tilted in the same manner as the above-described tilting of the bobbin. By rotating the fiber rotating part 31 in this direction, the multi-core fiber 1 passing through the fiber rotating part 31 can be rotated. Therefore, the position of the core 5 in the cross section perpendicular to the longitudinal direction of the multi-core fiber 1 sent to the tape resin coating portion 21 can always be kept constant.
- the same effect as that of the first embodiment can be obtained. Further, since it is only necessary to control the posture of the small roller as compared with the bobbin 12, the control is easy.
- FIG.8 (b) is a figure which shows the optical fiber tape cable manufacturing apparatus 20c.
- the optical fiber ribbon manufacturing apparatus 20c is substantially the same as the optical fiber ribbon manufacturing apparatus 20b, but the installation location of the fiber rotating unit 31 is different.

Description
また、テープ心線同士の接続、テープ心線と光素子等の接続において、より接続損失を低減することが望まれている。接続損失を低減するにはコア同士の軸ずれをより小さくする必要があり、テープ心線において、各光ファイバの偏芯方向を一定方向に揃えて光ファイバを整列させることが望ましい。
また、全ての光ファイバがすべて同一の方向に向くように配置されてもよく、または、互いに垂直な向きとなるように配置されてもよい。
以下、本発明にかかるテープ心線について説明する。図1(a)はテープ心線10の断面図である。テープ心線10は、複数のマルチコアファイバ1が併設されて、テープ樹脂被覆9で一体化されたものである。なお、テープ心線10を構成するマルチコアファイバ1の本数は、図示した例には限られない。
次に、第2実施形態について説明する。第1実施形態では、光導入部13をマルチコアファイバ1の端部とした例について説明した。この方法によれば、特定のコアのみを選択して光を導入することができる。これに対し、他の方法でマルチコアファイバ1に光を導入することもできる。

図11(a)は、テープ心線30を示す図である。テープ心線30は、テープ心線10と略同様であるが、マルチコアファイバ1dの外周面に着色部33が設けられる点で異なる。クラッド3の外周の樹脂被覆部7の外面の周方向の一部には、着色部33が形成される。着色部33は、マルチコアファイバ1dの長手方向に連続または断続して形成される。
図14は、マルチコアファイバ1bからなるテープ心線30bを示す断面図である。マルチコアファイバ1bは、マルチコアファイバ1とほぼ同様の構成であるが、クラッド3aが略しずく形である点が異なる。すなわち、クラッド3aは非真円形である。なお、樹脂被覆部7の断面外形は略真円形状である。また、樹脂被覆部7の中心とクラッド3aの中心は略一致する。
図18は、マルチコアファイバ1cを用いたテープ心線30cの断面図である。マルチコアファイバ1cは、マルチコアファイバ1cの長手方向と垂直な断面において、クラッド3と樹脂被覆部7の中心位置は略一致する。一方、マルチコアファイバ1cの長手方向と垂直な断面において、マルチコアファイバ1cの中心の位置と、コア群の中心の位置は異なっている。
