Abstract
An optical printed circuit board having an optical waveguide of at least one channel formed therein is provided. The optical waveguide of the at least one channel is stacked in the optical printed circuit board, and has both ends exposed on a surface of the optical printed circuit board and a predetermined length. An optical module is provided which can be optically aligned with the optical printed circuit board or another optical component through guide pins inserted into guide holes.
