Abstract

A transceiver assembly includes a frame section, a rigid printed circuit board, a flex circuit, and an edge connector. The frame section includes a flex circuit layer for use in carrying data, and control and power signals, and an optoelectronic device. The rigid printed circuit board includes a first rigid printed circuit board layer and a flex circuit layer for use in carrying data, and control and power signals. The flex circuit is for carrying data, and control and power signals which flexibly links the rigid printed circuit board to the frame section and forms the flex circuit layers in the rigid printed circuit board and the frame section. The edge connector is formed on one end of the printed circuit board by a plurality of connection pads disposed along one edge of the printed circuit board.

Claims

1. A transceiver assembly for use in fiber optics communications, the transceiver assembly comprising:

a) a frame section including a flex circuit layer for use in carrying data, control and power signals, and an optoelectronic device containing a set of photoactive components;

b) a rigid printed circuit board including a first rigid printed circuit board layer and a flex circuit layer for use in carrying data, control and power signals;

c) a flex circuit for carrying data, control and power signals which flexibly links said rigid printed circuit board to said frame section and forms the flex circuit layers in said rigid printed circuit board and frame section; and

d) an edge connector formed on one end of said rigid printed circuit board by a plurality of connection pads disposed along one edge of said printed circuit board, and wherein

said rigid printed circuit board includes a second rigid printed circuit board layer and said first and second rigid printed circuit board layers are positioned on either side of said flex circuit layer.
