Abstract: An optical data transmission link with improved fiber utilization. VCSEL and detector elements are configured on an optical matrix array with allocated surface area footprints at standard industry pitch dimensions, the elements of alternate rows and columns being offset from centerline of their footprints in opposite directions so as to create a pattern of sets of two or four adjacent optical elements operating at a common or differential wavelengths. A connector provides offset alignment of the fiber bundle to the matrix array so as to align a single fiber of standard industry diameter equal to the pitch of the array, with the center of each multi-element set so the fiber core diameter spans all elements of the set. The required modification to standard commercial mask design and chip fabrication is within the scope of present fiberoptic technology.
