線ユニットに関するものである。Detailed Description of the Invention The present invention provides a tape optical system in which a plurality of optical fibers are arranged in the same plane and fixed in a tape shape, and a plurality of tape optical fiber cores are stacked and housed in a pipe. This invention relates to a fiber core unit.
従来のテープ光ファイバ心線ユニットは、複数枚のテー

であった。A conventional tape optical fiber core unit is a structure in which a plurality of tape optical fiber cores are simply stacked and housed in a pipe.
このようなテープ光ファイバ心線ユニットの場合には、
積層のためにテープ面に対し直交する方向の側圧が加わ
シ、光ファイバの伝送特性を劣化させる欠点があった。In the case of such a tape optical fiber core unit,
Due to the lamination, lateral pressure is applied in a direction perpendicular to the tape surface, which has the disadvantage of deteriorating the transmission characteristics of the optical fiber.

た。If a lateral pressure is applied to such a tape optical fiber core unit from a direction that intersects +f with the tape edge surface, a large lateral pressure will be applied to the optical fiber at the widthwise end of the tape optical fiber core. This has the drawback that the transmission characteristics of the optical fiber strands subjected to the large lateral pressure deteriorate, and the transmission characteristics of the optical fiber strands within the same tape become uneven.

ニットを提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a tape optical fiber core unit that can prevent large lateral pressure from being applied to the optical fiber even if lateral pressure is applied in a direction perpendicular to the tape surface or tape edge surface.

That is.
以下本発明の実施例を図面を参照して詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.

している。FIG. 1 shows a first embodiment of the present invention. The tape optical fiber core unit of this embodiment includes a plurality of tape optical fiber cores 2 stacked and housed in a pipe 1 made of metal, plastic, or a composite laminate thereof. Each tape optical fiber core wire 2 has a plurality of optical fiber elements m3 provided with a buffer M% such as silicone resin on the outer periphery of the optical fiber arranged in the same plane, and reinforced with high Young's modulus fibers on both sides of this array. Side pressure receiving wires 4 such as plastic wires or steel wires are arranged, and these are fixed together in a tape shape with a tape covering 5 such as nylon, and lateral pressure receiving portions 6 are provided at both ends of the tape in the width direction by the lateral pressure receiving wires 4. Each has a unique structure. Each side pressure receiving wire 4 has a diameter larger than that of the optical fiber wire 4.

することができる。In this way, when lateral pressure is applied in the stacking direction, the lateral pressure receiving portion 6 receives the lateral pressure, so that no lateral pressure is applied to each optical fiber strand. Also, when lateral pressure is applied in a direction perpendicular to the tape edge surface,
Since the lateral pressure receiving portion 6 receives this lateral pressure, it is possible to reduce the large lateral pressure acting on the optical fiber strand 3 at the end in the tape width direction.

In this embodiment, thick portions 7 in the thickness direction are provided in the tape coating 5 at both ends in the width direction of each tape optical fiber core 2, and these thick portions 7 form side pressure receiving portions 6. ing. Further, a mining tape 8 such as a hard f2 stick or the like is disposed at both ends of each tape optical fiber core 2 in the stacking direction, and is housed in the f knob 1.

は側圧がかからないという利点がある。As explained above, in the tape optical fiber core unit according to the present invention, lateral pressure receiving parts are provided at both ends of each tape optical fiber core in the width direction, so that when lateral pressure is applied in the stacking direction, When the lateral pressure receiving part receives lateral pressure, lateral pressure is applied to the optical fiber strand, and when lateral pressure is applied in the direction perpendicular to the tape edge surface, other lateral pressure is applied to the optical fiber strand at the end in the tape width direction. It is possible to suppress deterioration of transmission characteristics due to lateral pressure greater than that applied to the optical fiber wire. The tape optical fiber core used in the present invention (having side pressure receivers at both ends in the width direction) can also be wound spirally around a long core material with a circular cross section to form a cable. In such applications, the lateral pressure due to winding is received by the lateral pressure receiving portions at both ends, so there is an advantage that no lateral pressure is applied to the optical fiber strand.
