A low-profile, mass-producible, unitary injection molded optical ribbon attachment structure includes a ribbon retaining portion, a light reflecting portion, and a plurality of lens portions. An end portion of a fiber optic ribbon cable is disposed in a ribbon retaining groove in the ribbon retaining portion. The unitary structure is fixed onto a bottom major surface of a circuit board. In a transmit application, light emitted from an optoelectronic component disposed on a top major surface of the circuit board passes down through a hole or slit in the circuit board, into one of the lens portions, then reflects off a planar light reflecting surface of the light reflecting portion and is redirected approximately ninety degrees, and then passes substantially parallel to the bottom major surface of the circuit board and enters the end of the fiber optic ribbon cable. In a receive example, light passes the opposite direction.
