Abstract
A method and apparatus for variable attenuation of a flexible optical waveguide empart a variable curvature to the waveguide such that selected, conditioned radition losses result. In one embodiment the curvature is emparted by winding a portion of the waveguide around a grooved roller, in other embodiments the curvature is emparted by slides which are laterally moveable within curved recesses of a supporting frame, the slides engaging the waveguide and causing the waveguide to conform to varying portions of the curved recesses.
