  • Variable attenuator for optical fiber applications
    Patent number: 6707980
    Abstract: A variable attenuation device for optical signal transmission has first and second ferrules or plugs having abutting end faces, one of the ferrules being rotatable with respect to the other while axial alignment therebetween is maintained. Each ferrule or plug has an axial bore aligned with the other and contains the end of an optical fiber, with a fiber having a smaller diameter than the diameter of the bore in which it is contained so that the fibers may have decreased engagement with each other when there is relative rotation of the ferrules although the ferrule bores remain aligned.
    Type: Grant
