Optical interface and splitter with micro-lens array

A method for producing an optical interface module, the method comprising:

• mounting an optical connector for connecting to external optical fibers that connect first and second optical signals to the optical interface module;
• mounting a first optical ferrule perpendicularly to the optical I/O connector, for transferring the first optical signals between the optical I/O connector and respective first optical transducers that are mounted on a first substrate, via first holes formed in the first substrate;
• mounting a second optical ferrule perpendicularly to the optical I/O connector, for transferring the second optical signals between the optical I/O connector and respective second optical transducers that are mounted on a second substrate, via second holes formed in the second substrate;
• connecting the optical I/O connector to the first and second optical ferrules by a light rotation module, which bends and transfers the first and second optical signals between the optical I/O connector and the perpendicularly-mounted first and second optical ferrules;
• and
• mounting one or more lenses between the first ferrule and the first holes, so as to couple the first optical signals via the first holes between the first ferrule and the first optical transducers.

A method for communication, comprising:

• transferring first and second optical signals carried on external optical fibers using an optical connector;
• transferring the first optical signals between the optical I/O connector and respective first optical transducers mounted on a first substrate, via first holes formed in the first substrate, using a first optical ferrule mounted perpendicularly to the optical I/O connector;
• transferring the second optical signals between the optical I/O connector and respective second optical transducers mounted on a second substrate, via second holes formed in the second substrate, using a second optical ferrule mounted perpendicularly to the optical I/O connector;
• bending and transferring the first and second optical signals between the optical I/O connector and the perpendicularly-mounted first and second optical ferrules, using a light rotation module;
• and
• coupling the first optical signals via the first holes between the first ferrule and the first optical transducers using one or more lenses that are mounted between the first ferrule and the first holes.
