Abstract:
1. A method of coupling block type multichannel optical signals in a multi-layer Printed Circuit Board (PCB), comprising the steps of: i) forming one or more first optical via holes to allow one or more first optical signal coupling blocks to be inserted therein; ii) aligning a first optical waveguide and the first optical signal coupling blocks so that the first optical waveguide is interconnected to the first optical signal coupling blocks via an optical signal; iii) attaching a first fixing guide to a base board to fasten the first optical signal coupling blocks; iv) removing the first fixing guide and forming one or more second optical via holes to allow one or more second optical signal coupling blocks to be inserted therein; and v) repeatedly performing steps i) to iv) as many times as the number of layers of the multi-layer PCB; wherein the last fixing guide is attached to and maintained in the base board.
