ABSTRACT:
A system is disclosed for optically coupling one or more electrical signals to one or more optical waveguide members. A terminating block has embedded therein a first plurality of collimating cylindrical lenses protruding from a first end of the block. A plurality of fibers, arranged longitudinally with respect to the lenses, are additionally embedded in the block and exit the block through a second end. Outside of the block, the fibers are surrounded by a protector. A redirecting assembly defines a port, sized to receive the terminating block. Also defined within the assembly is a transverse aperture having a plurality of circularly enlarged regions. The assembly has a prism secured therein. The prism is positioned so that it is aligned with the first plurality of lenses when the block is fully inserted into the port. An integrated circuit package contains a plurality of light-emitting or light-detecting devices having one or more leads. The light-emitting or light-detecting devices are positioned within substantially cylindrical holes defined in a base of the integrated circuit package. Connected to each device is a collimating cylindrical lens that protrudes into the assembly and is aligned with the prism when the assembly is affixed to the base of the integrated circuit package.
