ABSTRACT:
A flexible printed circuit board (FPCB) for fiber optic modules includes a board with multiple bends, forming a structure with sides and a bottom. The traces in the FPCB traverse from the opto-electronic chips, through the sides of the FPCB, to the module interconnects at the bottom. The multi-fold structure allows the FPCB to support a higher number of traces than conventional single-fold FPCB's, and it allows the fanning out of signal traces from the opto-electronic and electronic chips at the front of the fiber-optic module, thereby reducing the crosstalk between the traces. This higher number is provided with a FPCB that features a single insulating layer and without the need to criss-cross the traces, resulting in improved signal integrity over conventional multi-layer FPCB's.
