摘要： A host adaptor is configured to monitor operation of an optoelectronic transceiver. The host adapter includes a transceiver interface, memory, comparison logic and a host interface. The transceiver interface receives from the optoelectronic transceiver digital values corresponding to operating conditions of the optoelectronic transceiver. The memory includes one or more memory arrays for storing information related to the optoelectronic transceiver, including the digital values received from the optoelectronic transceiver. The comparison logic is configured to compare the digital values with limit values to generate flag values, wherein the flag values are stored in predefined flag storage locations within the memory during operation of the optoelectronic transceiver. The host interface enables a host device to read from host specified locations within the memory, including the predefined flag storage locations, in accordance with commands received from the host device.

摘要： A controller (110) for controlling a transceiver having a laser transmitter and a photodiode receiver. The controller includes memory (120, 122, 128) for storing information related to the transceiver, and analog to digital conversion circuitry (127) for receiving a plurality of analog signals from the laser transmitter and photodiode receiver, converting the received analog signals into digital values, and storing the digital values in predefined locations within the memory. Comparison logic (131) compares one or more of these digital values with limit values, generates flag values based on the comparisons, and stores the flag values in predefined locations within the memory. Control circuitry (123-1, 123-2) in the controller controls the operation of the laser transmitter in accordance with one or more values stored in the memory. A serial interface (121) is provided to enable a host device to read from and write to locations within the memory. Excluding a small number of binary input and output signals, all control and monitoring functions of the transceiver are mapped to unique memory mapped locations within the controller. A plurality of the control functions and a plurality of the monitoring functions of the controller are exercised by a host computer by accessing corresponding memory mapped locations within the controller.

摘要： An impedance-matching electrical connection system (400), for use with high-frequency communication signals, includes a circuit board and a plurality of contact pads (404-4, 404-2) mounted on the circuit board. The contact pads are for coupling with a plurality of complementary connectors of an external electrical device. Each coupling is associated with an excess shunt capacitance. The electrical connection system further includes a plurality of inductive traces (408-n) mounted on the circuit board, each of which is connected to a respective contact pad, and is associated with a compensating series inductance. Additionally, the electrical connection system includes a plurality of signal lines (406-1) mounted on the circuit board, each of which is connected to a respective inductive trace. Each inductive trace is configured so that its associated compensating series inductance substantially offsets the excess shunt capacitance associated with the coupling between the contact pad connected to the inductive trace and a complementary connector.

摘要： Circuitry for monitoring the operation of an optoelectronic transceiver includes a sequence of interconnected signal processing circuits for processing an analog input signal and producing a digital result signal, where the analog signal represents one or more operating conditions of the optoelectronic transceiver. The sequence of signal processing circuits include gain circuitry for amplifying or attenuating the analog input signal by a gain value to produce a scaled analog signal, an analog to digital converter for converting the scaled analog signal into a first digital signal, and digital adjustment circuitry for digitally adjusting the first digital signal to produce the digital result signal. The digital adjustment circuitry includes shifting circuitry configured to shift an input digital signal in accordance with a shift value so as to produce a digital shifted signal. The digital result signal is stored in memory in predefined locations accessible by a host.

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： A receptacle that is configured to receive connectors of different types. If a connector of one type is received into the receptacle, the connector contacts engage one set of receptacle contacts. If a connector of another type is received into the receptacle, the connector contacts engage another set of receptacle contacts, and so forth for potentially other connector types and other contact sets. A communication system may also control which PHY circuitry communicates with the receptacle depending on which connector type is plugged into the receptacle.
