METHOD AND APPARATUS FOR IDENTIFICATION OF MULTIPLE FIBERS USING AN OTDR

摘要

Ih order to simplify and expedite identification of fibers (DF 1/1,..., DF2/4) in multi-fiber cables (DFl1 DF2), a method of identifying each of a plurality of fibers includes the steps of launching light into each of the fibers using an OTDR and applying a unique signature to each resulting OTDR trace by means of signature-applying means (EB) connected to a distal end of the fibers. The resulting plurality of OTDR traces have different signatures, enabling identification of each of the fibers by detecting its signature in the corresponding OTDR trace.
