Abstract
A fiber optic coupling device for providing simultaneous bi-directional transmission of optical signals within a single wavelength band over a single fiber optic link cable, including a coupler/connector which precisely aligns and longitudinally separates transmit and receive lightguide fibers and a fiber optic link cable. The cores of the transmit and receive lightguide fibers are tightly aligned with a minimum thickness of cladding for increased packing efficiency, and the end faces of the transmit and receive lightguides are maintained parallel to and a predetermined distance from an end face of the fiber optic link cable to ensure that reflected signals will not be detected as received signals and allow simultaneous distinguishable bi-directional communication of optical data within a single wavelength band.
