Patent number: 7406247Abstract: Devices, systems and methods for thermal testing of optoelectronic modules are disclosed. The device includes a frame member, a thermoelectric cooler, a plate in thermal contact with the DUT, a heat sink in thermal contact with the frame, and a metallic clip for attaching the thermal testing device to the module (DUT). The clip secures the thermoelectric cooler to the DUT. The method includes the steps of providing a testing apparatus having a printed circuit board with a test circuit formed thereon. The test board also has an electrical interface disposed in electrical communication with the test circuit, and a thermal testing assembly. A temporary electrical connection is formed between the DUT device and the interface. The thermal testing assembly is used to maintain a test temperature of the DUT device. A data stream is transmitted through the DUT device and then evaluated for adherence to a defined specification.Type: GrantFiled: August 13, 2007Date of Patent: July 29, 2008Assignee: Finisar CorporationInventors: Samantha R. Bench, John C. Dirkson, Darin James Douma

Patent number: 7378834Abstract: An electronic assembly tester for testing an electrical component of an optoelectronic device. The electrical component includes a transmit and receive port. The tester includes of a base, an arm, and a hinge. The arm includes a flex circuit and cables. The arm is rotated into a closed position to form a temporary electrical connection between the electrical component and the flex circuit. Other configurations for forming a temporary electrical connection between the test circuit and the electrical component are possible. The electrical component is evaluated by providing a data signal to the transmit portion of the electrical component and evaluating a return data signal obtained from the receive portion of the electrical component.Type: GrantFiled: October 28, 2003Date of Patent: May 27, 2008Assignee: Finisar CorporationInventors: Rudolf J. Hofmeister, Konstantinos G. Haritos, John C. Dirkson, Samantha R. Bench

Patent number: 7317743Abstract: Systems and methods are provided for configuring an optoelectronic device so as to control various operating conditions at various temperatures. The method includes operating the optoelectronic device at a first temperature, adjusting a first control parameter of the optoelectronic device to satisfy a first operating requirement and recording an associated first value of the first control parameter. Further, the method includes operating the optoelectronic device at a second temperature, adjusting the first control parameter of the optoelectronic device to satisfy the first operating requirement, and recording an associated second value of the first control parameter. From the first and second recorded values of the first control parameter, a sequence of values for the first control parameter for a corresponding sequence of temperatures in a predefined range of temperatures is determined and stored in a programmable device within the device.Type: GrantFiled: October 28, 2003Date of Patent: January 8, 2008Assignee: Finisar CorporationInventors: Rudolf J. Hofmeister, Samantha R. Bench, Dmitri Bannikov

Patent number: 7230961Abstract: An exemplary optoelectronic transceiver 100 incorporating features of the present invention is shown in FIGS. 2 and 3. The transceiver 100 contains a receiver circuit, a transmitter circuit, a power supply voltage 19 and ground connections 20. The receiver circuit of the transceiver includes a Receiver Optical Subassembly (ROSA) 102, which may contain a mechanical fiber receptacle as well as a photodiode and pre-amplifier (preamp) circuit. The ROSA 102 is in turn connected to a post-amplifier (postamp) integrated circuit 106, the function of which is to generate a fixed output swing digital signal which is connected to outside circuitry via the RX+ and RX? pins 17. The postamp circuit 106 also often provides a digital output signal known as Signal Detect or Loss of Signal indicating the presence or absence of suitably strong optical input. The postamp circuit 106 does not necessarily have to be used to generate the Signal Detect or Loss of signal.Type: GrantFiled: February 10, 2005Date of Patent: June 12, 2007Assignee: Finisar CorporationInventors: Ruldolf J.
