。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a high-density and compact multi-core optical fiber cable for communication that can be manufactured economically using a simple manufacturing method. 11ti side, l is a polyethylene jacket, 2 is a ribbon unit, and 8 is a tensile strength member.

光ケーブルの経済化に有利である。This optical cable has a structure in which two ribbon units 2 are housed in a rectangular space formed by a polyethylene jacket 1, and tensile strength members 8 are provided at both ends of the cable. The feature of this optical cable is that it only takes one process to turn the ribbon unit into a cable.
This is advantageous for economicalization of optical cables.

イバの信＄１性の点で問題が多い。However, increasing the number of optical fibers in this type of cable has been difficult in terms of manufacturing and technology. In other words, stacking a large number of ribbon units is one way to increase the number of fibers, but since the cable does not have a twisted structure, when the cable is bent, the unit on the center of curvature receives compressive strain, and the unit on the opposite side receives compressive strain. Since the unit is subject to stretching strain, there are many problems with respect to the reliability of the optical fiber.

時における作業性、歩留りが低下するという欠点があっ
た。Another possible method is to increase the number of fibers in the ribbon unit, but this approach has limitations in terms of manufacturing workability and manufacturing yield. That is, in order to manufacture a multi-core ribbon unit, it is necessary to line up as many payout bins as the number of cores, which is difficult to assemble due to poor operability. Furthermore, if the number of core wires in Ripon Units is too large, there is a drawback that workability and yield during batch connection are reduced.

、図面を参照して本発明の実施例について説明する。In order to eliminate the above-mentioned drawbacks, the present invention integrates ribbon units with approximately 5 or 10 fibers, which are easy to manufacture, using a resin with a small Young's modulus, so that the ribbon units can be easily separated from each other when connected, and are easy to operate. The purpose of the present invention is to provide a flat optical cable that facilitates Embodiments of the present invention will be described below with reference to the drawings.

Further, in order to easily identify the core wires, different colors are applied to two ribbon unit assemblies along the long axis of the ribbon unit assemblies 5 at one end of the ribbon unit assemblies 9Ji5. At both ends of the cable sheath 1, which has a flat cross-sectional shape, this cable sheath 1 is provided.

By using a ribbon unit assembly in which a plurality of core or 10-fiber ribbon units are assembled in a flat shape, a high-density optical cable that is easy to manufacture can be obtained, and economical efficiency can be achieved. In other words, in order to increase the number of fibers in a flat optical cable, it is possible to increase the number of fibers included in the ribbon unit, but ribbon units with multiple fibers such as 80 or 50 fibers are not easy to manufacture. However, the yield will decrease. However, according to the present invention, it is possible to obtain a substantially multi-core unit that is superior in terms of manufacturing workability and yield. In addition, the ribbon unit with 5 cores or 10 cores is

At this time, if the resin used to form the ribbon unit assembly is softer than the coating resin of the ribbon unit, the ribbon unit can be easily separated, which has the advantage of improving workability.
