Abstract
A fiber optic cable has a light-exiting face. A cable-adapter is affixed to the light-exiting face. The cable-adapter has a cylindrical outer surface, a diameter of which is gradually tapered down. Light leaving the face of the cable is moved towards an optical receptor and gradually converged, by virtue of the tapered cylindrical surface, of the cable-adapter and emitted. In this manner, an optical loss is minimized. To prevent a leak through the tapered surface, the tapered surface is coated with a low refractive index film. Further, a ferrule is used to position the cable-adapter relative to the fiber optic cable. By virtue of this configuration, an optical leakage can be minimized when the light is received by an optical receptor having a small surface chip.
