Claim:
1. A package framework for a photoelectric conversion module, comprising: a first printed circuit board; a second printed circuit board; a flexible printed circuit board, one end thereof being connected to the first printed circuit board while the other end being connected to the second printed circuit board, the flexible printed circuit board having a plurality of signal lines, which construct signal transmission paths between the first printed circuit board and the second printed circuit board, wherein the flexible printed circuit board has a ground electrode disposed thereon, and the ground electrode has a band stop filter fabricated thereon; an optical device mounted on the second printed circuit board, for converting electronic signals into optical signals and converting the optical signals into the electronic signals; and a driver chip mounted on the first printed circuit board, for processing the electronic signals transmitted from the optical device and the electronic signals that are to be transmitted to the optical device; wherein the optical device receives the optical signals transmitted from outside and converts the optical signals into the electronic signals, and after that, the electronic signals are transmitted to the driver chip sequentially via the second printed circuit board, the flexible printed circuit board, and the first printed circuit board; the optical device converts the electronic signals transmitted from the driver chip sequentially via the first printed circuit board, the flexible printed circuit board, and the second printed circuit board, into the optical signals and then the optical signals are transmitted to an external device.
