An optical path system includes a first block that further includes multiple first fiber optic guides, arranged in a first configuration to receive multiple first optical fibers, with one fiber in each guide. The optical path system further includes a second block comprising multiple second fiber optic guides, arranged in a second configuration to receive multiple second optical fibers, with one fiber in each guide, wherein a first face of the second block abuts a first face of the first block and wherein the first block is movable relative to the second block. The optical path system also includes micro-position adjusting mechanisms configured to move the first block relative to the second block to align the multiple first optical fibers with the multiple second optical fibers.
