Abstract
A unitary multi-fiber ferrule has micro-holes for optical fibers, and a plurality of lenses disposed adjacent the front end, each of the plurality of lenses optically aligned with one of the micro-holes and exposed to air. Multiple rows of optical fibers and lenses may also be used in the unitary multi-fiber ferrule. The lenses have a divergence half angle of between about 2 and 20 degrees and may also have protrusions on them acting as an antireflective coating.
