Abstract: The invention relates to a method for fabricating an optical plug connector, according to which the optical waveguide is immersed with the exposed optical fiber into a powdery adhesive and is withdrawn from the same, whereby particles of the powdery adhesive remain adhered to the surface of the fiber. The fiber with the adhered particles is then inserted into the bore of the ferrule of the plug connector and is fixed therein. The ferrule is heated to a temperature greater than or equal to the melting temperature of the adhesive and is maintained at this temperature.

Abstract: An apparatus (10) includes a pressure relief valve (12) for relieving air pressure from a passenger compartment (76) of a vehicle (66). The pressure relief valve (12) enables airflow from the passenger compartment (76) to atmosphere (78). The apparatus (10) also includes a member (14) for reducing noise entering the passenger compartment (76) as a result of a backflow of air through the pressure relief valve (12) from atmosphere (78) to the passenger compartment (76). The member (14) includes structure (112, 114) for attaching the member (14) to the pressure relief valve (12).
