Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a method for identifying an in-house wiring in a telephone exchange room or the like and an optical fiber cord for which identification is indicated, and relates to an environment in which innumerable communication lines drawn from a large number of communication cables are mixed. Below, it is effective to easily identify the cord number information (identification number) displayed on the jacket of each communication line.

[0002]

2. Description of the Related Art For example, in a telephone exchange room, a connector of a terminal is connected to an insertion port of the telephone exchange in a state where countless communication lines drawn from a large number of optical cables are mixed. An identification code (ID code) for identifying a communication line is attached to an optical fiber core wire built in each optical cable. On the other hand, the connection positions of the connectors of the individual optical fiber cords to the telephone exchange are changed for various reasons. In this changing work, it is necessary to confirm the ID code at the terminal of the optical fiber cord. However, the number of optical fiber codes to be identified is extremely large (2000 or 4000), and it is not easy to confirm the ID code assigned to each optical fiber code, and it takes considerable effort. By the way, the optical fiber cord (optical fiber cord) has a wire diameter of 1.7 m, for example.
The plastic ring (marker band) for identifying the number is fitted in the jacket at the base of the connector because it is extremely thin such as m, but the optical fiber cord is, for example, a jumper unit made up of 64 bundles. Therefore, after specifying the jumper unit, read the corresponding number from the jumper unit with a device and confirm it, and when trying to extract the optical fiber code, there is no number display in the code longitudinal direction, so dozens of It is extremely difficult to extract the optical fiber cord of the corresponding number from the inside, it takes an extremely long time, and the work efficiency is poor.

[0003]

However, if the corresponding number can be roughly divided and identified, the range to be identified by the identification number becomes narrower, and the identification of the corresponding number becomes simple and easy. Accordingly, it is an object of the present invention to enable a large number of optical fiber codes to be displayed in a roughly divided manner.

[0004]

Means taken to solve the above problem is to display a color bar adjacent to the identification number on an optical fiber code in which the identification number is written on a jacket, and to use the color bar to display the color bar. This is to display the numerical value of the specific digit of the identification number.

[0005]

The numerical value of the specific digit of the identification number is displayed by the color of the color bar, and a large number of optical fiber codes are roughly divided by the color of the color bar. Since the color bar is much larger than the identification number, it is easy to identify an optical fiber code having a specific digit in common with the group divided by this, that is, the identification number. Then, it is easy to identify the numerical value of the specific digit of the identification number by the color of the color bar and find the corresponding identification number from the optical fiber code displayed by the color bar of the same color. Since the color bar is displayed adjacent to the identification number, the above-described identification operation of the optical fiber code using the color bar and the identification number is easily and quickly performed.

[0006]

[Embodiment 1] Embodiment 1 is that the specific digit in the solving means is the largest digit.

[0007]

When the identification number of one block is two digits, the maximum digit is ten (10) digits. Since the tens digit is displayed with a color bar, the number of the remaining one (1) digit is 0-9. For example, since 50 to 59 are displayed with the same color bar, the optical fiber code having the same color bar is 10
It is a book. If the corresponding number is 55, it is sufficient to find 55 out of the above ten, that is, 50 to 59.

[0008]

[Embodiment 2] Embodiment 2 is that the specific digit in the solving means is the smallest digit.

[0009]

When the identification number of a block is two digits, the minimum digit is one (1) digit. For example, when the number of one block is 1 to 69, the number of the remaining ten (10) digits is 0 to 6 because one digit is displayed by a color bar. For example, when the corresponding number is 55, 05, 15, 25,.
It is easy to find the identification number 55 from the optical fiber code in which the same color bar of the book is written.

[0010]

Next, an embodiment will be described with reference to the drawings.
This embodiment is an example in which the present invention is applied to a jumper unit in which one unit has a bundle of 64 optical fiber cords and forms one unit, and a tens digit is displayed by a color bar. As shown in FIG. 1, each optical fiber code 1 has an identification number 2 and a color bar 3 adjacent thereto, and in this example, the identification number 2 and the color bar 3 are alternately and repeatedly printed. . The length of the color bar 3 is 5-10
mm, but the longer the color, the easier it is to see the color. The display categories by color are as follows. Fiber optic cable identification number Color of carab 00-09 Blue 10-19 Yellow 20-29 Green 30-39 Red 40-49 Purple 50-59 Orange 60-64 Gray Determine color order according to any rules Thus, a numerical value corresponding to a specific color bar can be accurately recognized based on the rule. When the number of optical fiber cords in one unit is less than 90, the number of ten digits is nine. Therefore, in order to minimize the number of colors, it is desirable to display the number of ten digits with a color bar. . However, the number of optical fiber cords per unit is 10
If the number exceeds 0, it is desirable to display the one digit by color coding of the color bar in order to minimize the number of color coding.

[0011]

[Others] As another application of the present invention, for example, 100 to 1
Since the hundreds digit is common to 99, it is indicated by a black color bar, for example, and the first two digits are represented by a color bar combining this with the color bar representing the tens digit in the above embodiment. You just need to display the number. In the case where the number exceeds 100, the color bar which combines the color representing the hundreds digit and the color representing the tens digit is used to identify the object of the optical fiber code to be identified by the identification number. The number can be similarly reduced. Also, for the same color, the above color bar,
By displaying in combination with a black color bar as an example, if the black color bar specifies 0 to 5 or 6 to 9 out of 0 to 9, the range to be identified by the identification number can be halved. it can. Further, if the object to be displayed by the color bar is not limited to the digit of the identification number, for example, the identification numbers 1 to 10, 11 to 20, 21 to 21
10, 31 to 40, 41 to 50, and 51 to 60 can be displayed as a single unit and displayed as a color bar. In this manner, 10 units identified by the same color bar can be displayed. All you have to do is find the one with the corresponding number from the book.

[0012]

[Effect] As described above, in a wiring in a place where a large number of optical fiber cords drawn from a large number of communication cables are mixed, an identification number is displayed on each optical fiber code together with an identification number by a color bar adjacent thereto. By doing so, the number of optical fiber codes to be identified by the identification number can be easily reduced, the identification symbol by this color bar can be confirmed at a glance of the optical fiber code, and while relying on the identification symbol by the color bar, The identification number assigned to each optical fiber code can be checked relatively easily and quickly.
