A data link for transmitting data between first and second optically active devices, such as in articulated electronic devices. A coupling unit is mounted above each optically active device. Each coupling unit has a convexly tapered well extending between a top surface and a bottom surface, with a larger opening in the top surface and a smaller opening at the bottom surface. The tapered well receives one end of the optical fiber and aligns the end with the corresponding optically active device. The smaller opening of the well may have a circular cross-section or a keyhole cross-section. A groove may be disposed near a top surface of each coupling unit, with the groove extending between the tapered well and a sidewall of the coupling unit. A segment of the optical fiber disposed near an end curves along the contour of the convexly tapered sidewalls when the optical fiber is inserted into the groove. A pair of opposed lips retain the optical fiber in the groove.
