High Capacity 1 Tbps (20 Gbps/ch × 24 ch × 2 layers) multilayer optical printed circuit board with high optical coupling efficiency and low-power transmitter module

We developed a high-speed (20 Gbps/channel) and large-capacity (1 Tbps/board) optical printed circuit board with a proposed two-lens optical coupling structure and a low-power (7.1 mW/Gbps) optical module using a CMOS IC, and successfully demonstrated 20-Gbps/ch operation in our optical interconnection.
