(Prior Art) In a subscriber system, a telephone line is connected from a station to each subscriber, and the number of the lines is the same as the number of subscribers. If this subscriber system becomes an optical cable, the feeder cable will be 100
Since it is an optical fiber of 0 core, it becomes thicker. Therefore, as the feeder cable, five tape-shaped fiber cords are used, and the tape-shaped fiber cords are assembled to thin the multi-core feeder cable. A tape-shaped fiber core wire and a standard GI cable are connected by a connector at a point where the feeder system rises from the feeder system to the subscriber system. In the case where a few of these five fiber-shaped tape-shaped cores are used and a few of them are not used, the unused fiber-core cannot be found conventionally without affecting the working signal. It was

(Structure of the Invention) The method of checking the core fiber of the tape-shaped fiber core of the present invention is to bend the tape-shaped fiber core and apply a slit plate curved along this bending to this bent portion to attach the slit plate to the fiber core. It is characterized in that the unused cores are found by taking out the output of the individual fiber cores so that the slits correspond to each other.

(Embodiment) An embodiment of the present invention will be described in detail with reference to the drawings, and FIGS. 1 and 2 schematically show a method of checking the core wire of a tape-shaped fiber core wire according to the present invention. In this method, a tape-shaped fiber core wire 10 is bent, and a slit plate 14 curved along this bending is applied to the bent portion 12 of the slit plate 1.
4 is sequentially moved in the width direction of the tape-shaped fiber core wire 10 for each measurement so that the slits 16 correspond to the individual fiber core wires 10a (see FIG. 3) in sequence, and the output of each fiber core wire 10a is obtained. Find unused cores by ejecting.

The photodetector 18 faces the slit 16 of the slit plate 14.
The photodetector 18 is integrally attached to the slit plate 14 by a frame 20. Since the slit 16 has a width corresponding to the width of each fiber core wire 10a, the photodetector 18 detects an optical signal when the slit 16 corresponds to the fiber core wire 10a in use, and the unused fiber cores are detected. When the slit corresponds to the line 10a, the optical signal is not detected. Therefore, the unused fiber core wire 10a can be easily found. Since the optical signal passes through the fiber core wire 10a only during a call, it is determined whether the fiber core wire 10a is in use or not by making a call through each subscribed fiber core wire 10a.
