Identification system for optical fiber transmission operation lines with local-light injection and detection coupling system

An identification system using a local-light injection and detection coupling system is developed. The relation of bending fiber radius to both local-light injection and detection coupling efficiencies is shown. This system can be used for distances of up to 21 km at a bending radius R=7 mm. Also, the line number in the fiber ribbon, can be confirmed and transfer splicing loss can be estimated using this identification system.<
