Fiber optic transceiver (FOT) module and method for manufacturing an FOT module

A fiber optic transceiver (FOT) module is provided that has a circuit board attached to the FOT leadframe. The circuit board, which is typically a printed circuit board (PCB), provides several advantages over typical FOT module designs in that it provides additional surface area for mounting additional components, enables components to be moved from the motherboard into the module, allows the I/O pin count of the FOT module to be increased without increasing the width or footprint associated with the module, allows bond wires to be shortened, provides improved performance over changes in temperature, allows manufacturing yield to be improved, and enables improvements in signal integrity to be realized.
