Methodology for finding damaged sections of Fiber Optic cables where the minimum bend radius or the maximum pulling tension has been exceeded .

In the telecommunications industry and in data centers worldwide, a significant quantity of fiber optic cables are routed both within the facility and in between facilities. These cables must be installed with great care so as to not exceed the minimum bend radius or the maximum pulling tension of the cable so as to not damage the glass fibers inside. The glass fiber is very strong if pulled and installed correctly but is very fragile if bent or kinked too sharply. Damaged cables can hinder performance immediately or over time where open or broken cables kill the performance altogether. Similar damage can occur if the maximum pull tension of the cable was exceeded during cable installation when the cable was pulled through conduits or strung overhead in exterior applications. Finding the location of the damage to the cable can be very problematic in large installations or in long runs between installation sites.

    Proposed here is a coating on the exterior jacket of the fiber optic cable that changes colors when the cable is unduly stressed, where the minimum bend radius or the maximum pulling tension of the cable has been exceeded. Enhancing the identification visually of where the damage to the cable has occurred, and making for easy problem spot identification with a visual inspection of the cable. The coating for the b...
