Abstract: Disclosed herein is an architecture of connecting a transceiver module for an optical PCB, in which an active photo-electric element and other components to be integrated in the optical PCB having waveguides are packaged, waveguides arranged in the optical PCB, and an optical connection block for optical coupling between the transceiver module and the waveguides of the optical PCB. Guide pin insertion holes are formed at one sides of the ends of the waveguides such that the optical PCB, the transceiver module and the optical connection block can be passively aligned using guide pins inserted into the guide pin insertion holes.

Abstract: Disclosed is an optical printed circuit board (PCB) having a multi-channel optical waveguide, which comprises: an optical waveguide having an optical path for transmitting light beams; a groove for penetrating the optical waveguide; and an optical interconnection block inserted in the groove and connected to the optical waveguide to transmit the light beams, wherein the optical interconnection block includes an optical fiber bundle bent by the angle of 90°. The optical interconnection block connects a plurality of multi-layered optical waveguides to transmit light beams to the optical waveguides. The optical fiber bundle is installed as a medium of the multi-channel optical waveguide in the optical PCB.
