Abstract
A star coupler comprises a flexible optical ribbon curved so that input and output fibers attach to the same side of the coupler. A connector mates a linear array of fibers to each end of the ribbon. The side walls of the ribbon are rounded to match the contour of the outboard fibers of each array. The ribbon thickness is about 91% of the fiber diameter to minimize insertion loss.
