Fiber optic cable marking process and a sensor device for use therewith

摘要

A mark sensor and methods for detecting a core mark disposed on a fiber optic cable core having a core receiving area for receiving the fiber optic cable core. The mark sensor includes emitter/receiver sensor devices that can be disposed about the core receiving area for observing a portion of the core for detecting the core mark. The mark sensor can include a sensor positioning system for moving the sensors relative to the core receiving area. The sensor positioning system is operative to move the sensors upon insertion of the cable core in the core receiving area. The sensor positioning system can include a linkage to another mark sensor for transmitting sensor motion to the other mark sensor. Alternatively, the mark sensor can include stationary sensors that sweep the core with radiation, for example, a bar code reader. Methods for using the foregoing sensors can result in the direct or offset marking of reverse oscillation of lay areas in a fiber optic cable.
