Abstract (en)
Components for security systems inserted between fiber optic cables (20,22) in an optical path comprised of means for light emission (36) and means for light detection (40), said componenets containing optical reflection couplers (14) served by cable connection means (82) for tips of fiber optic calbles (20,22) to said couplers (14) and reflecting means (90) for returning a light beam, exiting from a first fiber optic cable (20) connected to the light emission source (36), and to another fiber optic cable (22) connected to the light detection means (40). The invention also comprises security equipments (10,60) conatining said fiber optic components. <IMAGE>
