摘要： Methods and processes are disclosed for calibrating optoelectronic devices, such as optoelectronic transceivers and optoelectronic receivers, based upon a measured avalanche photodiode bit error rate. In general, the method involves measuring a bit error rate for the avalanche photodiode and adjusting the reverse bias voltage of the avalanche photodiode until the bit error rate is minimized. This process is repeated for each of a variety of different thermal conditions. Information concerning each thermal condition and the corresponding reverse bias voltage is stored in a memory of the optoelectronic device.

摘要： The present invention is an improved flow-metered pumping system using an air-backed diaphragm pump with load compensation. A variable motor speed controller is used to compensate for flow rate reduction caused by pressure effects. When the output pressure on the pump increases to a point where the load on the pump motor exceeds a specified threshold, the motor speed controller increases the speed of the motor to compensate for pressure induced diaphragm distortion losses and to achieve a substantially constant flow rate across a range of pump output pressures.

摘要： An optoelectronic transceiver includes first and second controller ICs. Each controller IC includes logic, a memory, an interface, and at least one input port. Each memory is configured to store digital diagnostic data and has a unique serial device address to allow a host access to each of these controller ICs separately and independently. At least some of the digital diagnostic data is common to both the first controller IC and the second controller IC. The inclusion of two controller ICs allows the same diagnostic data to be stored in completely different memory mapped locations. This allows hosts that are preconfigured differently to read different memory mapped locations on the different controller ICs to obtain the same diagnostic data.

摘要： The optical-transceiver module includes an optical transmitter and an optical receiver. The optical transceiver module also includes an internal serial bus and a plurality of addressable components electrically coupled to the internal serial bus. Each of the addressable components included a serial interface for communicating with the internal serial bus, and a memory. Each addressable component also includes a unique address or chip select logic coupled to a controller via a chip select line. This allows data to be addressed to specific addressable components. The addressable components may include a laser driver, a laser bias controller, a power controller, a pre-amplifier, a post-amplifier, a laser wavelength controller, a main controller, a electrothermal cooler, an analog-to-digital converter, a digital-to analog converter, an APD bias controller, or any combination of the aforementioned components.

摘要： Methods and processes are disclosed for calibrating optoelectronic devices, such as optoelectronic transceivers and optoelectronic receivers, based upon an avalanche photodiode breakdown voltage. In general, the method involves adjusting a reverse-bias voltage of the avalanche photodiode until avalanche breakdown of the avalanche photodiode occurs. An optimized APD reverse-bias voltage is then determined by reducing the reverse-bias voltage at which avalanche breakdown occurs by a predetermined offset voltage. This process is performed at a variety of different temperatures. Information concerning each temperature and the corresponding optimized APD reverse-bias voltage is stored in a memory of the optoelectronic device.
