【0010】 [0010]
また、識別用タグに書き込める文字数にも制限があり、必要な情報を全て記載することは不可能である。 Further, there is a limit to the number of characters that can be written to the identification tag, it is impossible to describe all the necessary information. また、識別用タグは刻印などで文字を書き込まれるが、識別用印字と同じように長期間経過すると文字がかすれて判別不能となることが生じるという問題点があった。 The identification tag is written characters or the like engraved, there is a problem that it becomes indistinguishable hoarse character when just as elapsed long time and identification printing occurs.
【0011】 [0011]
また、QRコード印刷紙、バーコード、磁気カード、ICカードなどが光ケーブルの外皮に貼着されているものは、書き込み情報が少ないことと、長期間経過したり、擦られたりすると識別不能となることが生じるという問題点があった。 Furthermore, QR code printing paper, bar codes, those magnetic card, an IC card is attached to the outer skin of the optical cable, becomes a possible write information is small, a long period of time or elapsed, and indistinguishable or rubbed that there is a problem that may occur.
【0012】 [0012]
なお、ケーブルの識別が必要となるのは、張り替えや撒去作業時に多数のケーブルから目的のケーブルを確定するためであるが、識別用印字や識別用タグやQRコード印刷紙、バーコードが不鮮明であったり、同じ内容の表示のケーブルが複数ある場合には、情報確定のために多くの時間がかかってしまうという問題点があった。 Incidentally, it is necessary to identify the cable, replacement or 撒去 but work in order to determine the purpose of the cable from a number of cables at, identification printing and identification tags and QR code printing paper, blurred bar code or even in the case where the display of a cable of the same contents are multiple, there is a problem that it takes much time for the information determined.
【0013】 [0013]
さらに、もし、間違ったケーブルを切断してしまった場合には、そのケーブルに流れる信号で制御されていた機器の誤作動や情報の停止が発生し、重大な事故になるという問題点があった。 Moreover, if, when you inadvertently cut the wrong cable, the cable of the equipment was controlled by the signal flowing erroneous stopping of operation and information occurs, there is a problem that a serious accident .
【0014】 [0014]
