Abstract

In this paper, we demonstrate a low-cost 48-channel high-speed flexible printed circuit (FPC) based interconnect packaging concept for on-board optical modules. Due to the good high-speed performance and low cost, the FPC board is used as the base carrier for both transmitter and receiver modules. The on-board transmitter and receiver are based on a commercial 1 mm pitch ISI HoLi pin grid array (PGA) connector. The size of each module is only 31.5 mm × 31.5 mm and offers a state-of-art bandwidth density of 0.483 Gbps/mm2 by using a compact design. Investigation of RF signal propagation on the FPC is carried out for design validation at 10 Gbps and, in order to further explore the potential of the suggested platform, differential pairs are simulated up to 30 GHz. The low-cost packaging approach requires only several flip-chip bonding steps using industry standard solder reflow and ultrasonic bonding processes. 8×12-channel optical straight lens connector are used to couple the light from the optics into two 48 fibers MPO connectors with 8×12-channel MT ferrules. The fully assembled transmitter and receiver are tested at 10 Gbps demonstrating error free operation with sensitivities comparable with those of commercial devices. Bit error rates (BER) for all 96 channels as well as representative eye diagrams at 10 Gbps are reported. IEEE
