Method and system for determining the location of a fiber optic channel along the length of a fiber optic cable

摘要: The location of one or more fiber optic channels ( 16 ) along the length a cable 12 is determined by: a) arranging an electrical conductor and magnetic source at known adjacent to least ); b) transmitting current through conductor, thereby deforming by Lorenz forces in vicinity source; c) conveying deformation deform channel d) light pulses using variations back reflected deformed determine ).
