Patent ID: 7062144

Claim:
An architecture of connecting an optical PCB, a transceiver module for the optical PCB, and an optical connection block including waveguides that change the direction of optical signals by 90° for optical coupling between the optical PCB and transceiver module, wherein guide pins are disposed on a top surface and a side of the optical connection block and located spaced apart by a predetermined distance from the ends of the waveguides; wherein a rectangular groove is formed in the optical PCB having waveguides arranged therein, for inserting the optical connection block thereto; wherein first guide pin insertion holes are formed at one side of the ends of the waveguides exposed from the side of the rectangular groove such that the guide pins disposed on the side surface of the optical connection block can be inserted into the first guide pin insertion holes; and wherein second guide pin insertion holes are formed in spacers located at one side of an active photo-electric element of the transceiver module for the optical PCB such that the guide pins disposed on the top surface of the optical connection block can be inserted into the second guide pin insertion holes, whereby the guide pins are inserted into the first guide pin insertion holes and the second guide pin insertion holes to connect the optical PCB, the transceiver module and the optical connection block to one another.
