OPTICAL CABLE LAYING RELATED INFORMATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical cable laying related information control method capable of easily recording and reading out the laying related information such as transmission loss data of each optical fiber or the like in a laying job site. SOLUTION: A QR cord printed paper 3 is stuck to an optical cable 1 laid in a pipeline or the like. The QR cord printed paper 3 has laying related information such as transmission loss data or the like on each optical fiber input from a personal computer in a laying job site, which is encoded and printed thereon, and at the time of maintenance, the cord printed paper 3 is scanned by a cord reader to read out the recorded information in the laying job site.
