Abstract
An optical adapter includes a loading plate and a coupling lens. The coupling lens includes a main body, a first optical reflector, and a second optical reflector. The first optical reflector is positioned on the loading plate. The main body includes a top plate made of transparent material and spaced a predetermined distance from the loading plate. The second optical reflector is positioned on the first top plate. The first loading plate loads a portion of a planar optical waveguide of an optical printed circuit board. An optical signal from the planar optical waveguide is reflected by the first optical reflector to the second optical reflector, then is reflected by the second optical reflector to the outside of the optical adapter.
