<p>A variable attenuator (10) for a fiber optic transmission system includes first and second optical fibers (18, 18') which are axially aligned. The fibers are provided with spherical polishes (30, 30'). The radius (R, R') of each of the polishes originates at an axis which is offset from an axis of the fiber cores (20, 20').</p> |
