Paper Abstract

One important advantage of fiberoptic communication is security. Compared with conventional electric cables, optical fiber cables are very hard to tap on information because no elctric or magnetic fields are generated from the cables. However, it is still possible to make an optical fiber to leak some of its power by peeling the jacket and bending the fiber or removing the cladding. Methods to pro-tect fiberoptic communication from tapping has been proposedl). In this paper we propose a new, simple but effective method bases on intermodal interference to protect multimode fiberoptic communication. The optical fiber detects any mechanical distortion of itself, which unavoidably occurs in an attempt to tap information. Although the lightwave carries both communication and security informations, we demonstrate that there is no degradation in communication quality.
