Abstract
Fiber optic transmitter and receiver electrical elements are implemented on separate vertical boards in fiber optic modules. An optical block implements lenses and reflecting surfaces to minimize manufacturing costs. The light receiver and light transmitter are mounted to receive and transmit non-orthogonal to the fiber axis to avoid optical cross talk. In one embodiment, receiver and transmitter are mounted at an angle greater than forty-five degrees with a perpendicular line to the reflective surfaces. In another embodiment, receiver and transmitter are mounted at an angle less than forty-five degrees with a perpendicular line to the reflective surfaces. The reflective surface for transmission may be a beam shaper to improve light beam uniformity and optical coupling and to avoid active alignment. The vertical boards have ground planes facing each other to minimize electrical cross talk. An optional shielded housing provides further shielding for reducing EMI.
