Cable connector assembly with two printed circuit boards

A cable connector assembly comprising:

• an insulative housing defining a mating portion;
• a plurality of contacts disposed in the housing with contacting sections exposed in the mating portion;
• a hard printed circuit board located behind the housing;
• a cable located essentially behind the hard printed circuit board and including a plurality of electrical wires and a plurality of optical fibers;
• said hard printed circuit board defining, along a front-to-back direction, a front end region to which the contacts are mechanically and electrically connected, and a rear end region around which the electrical wires are electrically connected and the optical fibers are optically connected via an opto-electronic conversion module and a flexible printed circuit board;
• wherein
• said flexible printed circuit board is electrically connected to the hard printed circuit board, and said flexible printed circuit board and the opto-electronic conversion module are connected to each other in a perpendicular manner.
