摘要： PROBLEM TO BE SOLVED: To easily cope with the case that a plurality of kinds of coated optical fibers are needed, to construct an efficient optical network and to reduce the cost of laying work. SOLUTION: An SZ slot type optical cable 11 is provided with a structure in which coated optical fibers 4 are housed in respective grooves 2 of an SZ grooved rod 3 having a plurality of spiral grooves 2 the directions of which are alternatively reversed. Plural kinds of coated optical fibers 4(4A, 4B and 4C) having different number of fibers are housed in the grooves 2 in one slot- type-optical cable 11. For example, five four-fiber tapes 4A, five two-fiber tapes 4B and six single fibers 4C are respectively housed in eight grooves 2. A demand for a plurality of kinds of coated optical fibers is easily met only by laying one optical cable, and it becomes possible to flexibly, efficiently and inexpensively cope with desires of optical line subscribers and network side. Even if many kinds of coated optical fibers are used, since existing grooved rods are allowed to use, the cost for design of a new slot type optical cable structure and new equipment is reduced. Also, a laying space for a conduit or the like is saved.

摘要： PROBLEM TO BE SOLVED: To perform highly precise slot phase detection and to prevent a coated optical fiber from disengaging from a slot in a collecting part. SOLUTION: A coated optical fiber collecting tool 20 is provided with a spherical body 22 having the outside diameter slightly larger than the width of the slot 4. The spherical body 22 is pressed against the opening edge of the slot 4 of a slot rod 3 by a coil spring 21. When the coated optical fiber collecting tool 20 is used as a collecting die in a coated optical fiber collecting process, since the spherical body 22 guides the coated optical fiber in the state that it comes into contact with the opening edge of the slot 4 without any gap, the coated optical fiber is surely prevented from springing out of the slot 4. Since play between the spherical body 22 and the slot 4 is not generated when the tool 20 is used as a slot phase detecting tool, highly precise phase detection is performed.
