Optical ferrules and optical ferrule molds

A molded unitary optical ferrule comprising:

• a molded first section molded by a first side of a mold molding one or more receiving elements of the molded unitary optical ferrule configured to receive and secure an optical fiber, and molding a light affecting element of the molded unitary optical ferrule for affecting one or more of a direction and a divergence of light propagating within the molded unitary optical ferrule, the affected light exiting the molded unitary optical ferrule through an output surface thereof;
• and
• an opposite molded second section molded by an opposite second side of the mold molding the output surface of the molded unitary optical ferrule, wherein the molded second section further comprises at least one second alignment feature, the second alignment feature comprising at least one planar surface, wherein the at least one planar surface is a first planar mating surface configured to slide on a planar mating surface of a mating optical ferrule and the first planar mating surface comprises a plurality of lands between a plurality of grooves.
