ABSTRACT:
Disclosed herein is an optical signal coupling block, and a multi-layer printed circuit board and the method for coupling optical signals between layers of a multi-layer printed circuit board (PCB) using optical signal coupling blocks. The optical signals between the layers are coupled through the steps of forming a plurality of optical via holes in the multi-layer PCB to which optical waveguides for transmitting optical signals are attached; inserting the optical signal coupling blocks into the plural optical via holes such that the optical signal coupling blocks are connected to the optical waveguides to transmit the optical signals; forming at least one connection part to couple optical signals between the optical waveguides and the optical signal coupling blocks; and interconnecting the optical waveguides and the optical signal coupling blocks by aligning positions of the optical waveguides and the optical signal coupling blocks.
