Abstract:
1. A passive alignment fiber optic connection system, comprising: a connector module having a plurality of fiber optic fibers having ends terminating at a face of said connector module; a substrate module having a plurality of waveguides having ends terminating at a first face or at a second face of said substrate module to define an input end and an output end which are different from each other; at least two pins projecting from one of said modules at pin locations; at least two pin passages within another of said modules at pin locations and through said face thereof, respective said pin passages being sized, shaped and positioned to receive respective said projecting pins, the pin passages and projecting pins being precisely sized to eliminate movement between the pin passages and projecting pins when the projecting pins are inserted into the pin passages; said ends of said fiber optic fibers are spaced from one another and from said pin locations of the connector module in accordance with a predetermined alignment pattern, and said ends of said waveguides are spaced from one another and from said pin locations of the substrate module in accordance with said predetermined alignment pattern, whereby each of said respective waveguides optically aligns with each of said respective fibers when said modules are attached together; and said substrate module includes at least two wafers assembled together, and prior to assembly a first said wafer has said plurality of waveguides positioned thereon, and after assembly a second said wafer opposes said first wafer and accommodates said plurality of waveguides positioned on said first wafer.
