摘要： 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.

摘要： An electro-optical assembly (EA) is provided in which the transmitter and receiver components are integrated together on a single circuit board, which is encapsulated in a single molded EA package. Integrating the transmitter and receiver components on a single circuit board allows the size and complexity of the EA to be greatly reduced as compared to the traditional TO-can and FOT architectures. A standard semiconductor inline automation system and process may be used to manufacture the EA packages so that they may be mass produced with improved throughput, yield and quality as compared to the method currently used to manufacture and assemble the known EA used in the traditional TO-can and FOT architectures.

摘要： Optical receivers and a method for providing a diagnostic measurement of optical modulation amplitude at other than a signal output of an optical receiver are invented and disclosed. The method includes the steps of applying a representation of an output of an optical detector to a circuit that determines a difference between a first signal level and a second signal level that is different from the first signal level and buffering the difference between the first signal level and the second signal level received from the circuit. The optical receivers include an optical detector, a transimpedance amplifier that applies automatic gain control, a circuit that determines a difference between two signal values and a limiting post amplifier. The receivers provide a diagnostic measure that can be compared to certain thresholds relating to known bit error rates or applied in a calculation to generate an absolute optical modulation amplitude value.
