ABSTRACT:
A method for labeling or coding optical conduits is disclosed. The method includes providing an optical conduit, and utilizing reflected light resulting from the transmission of at least one light pulse along the optical conduit to generate a multi-digit code. Still further, the method includes utilizing the multi-digit code to distinguish the optical conduit from other optical conduits. The utilization of Bragg gratings to code or label optical conduits with a unique multi-digit code is also disclosed.
