Title:
METHOD OF MONITORING STRAIN OF OPTICAL FIBER AND OPTICAL FIBER CABLE
Document Type and Number:
Japanese Patent JPS56124033
Kind Code:
A
Abstract:
At least one metallic element is incorporated into a cable during the manufacture of optical fiber cables, along with one or more elongated optical fibers. Such metallic element with its insulation is similar in diameter to an optical fiber with its sheath. The electrical resistance of the metallic element varies very little with temperature, but does vary with strain. Hence, by monitoring the resistance of the metallic element, the strain to which the fibers are subjected can also be monitored.
