    摘要: A loss of signal assert and de-assert level programming mechanism in an optical transceiver coupled to a host computing system. A control module is connected to the host so as to receive the programmable loss of signal level. A post-amplifier detects when the receive power drops below a loss of signal level. However, in this case, instead of the loss of signal level being static, a loss of signal level adjustment mechanism changes the loss of signal level detected by the post-amplifier as directed by the programmable loss of signal level received from the host. The loss of signal assert and de-assert levels may be calibrated by comparing receive power to the threshold for assertion and de-assertion of the loss of signal.

    摘要: The 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: 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.

    摘要: A controller for controlling the reverse-bias voltage of an avalanche photodiode in a transceiver or receiver. The controller includes memory for storing information related to the avalanche photodiode, and analog to digital conversion circuitry for receiving an analog signal corresponding to the temperature of the avalanche photodiode, converting the received analog signal into a digital value, and storing the digital value in a predefined location within the memory. Control circuitry in the controller controls the operation of the avalanche photodiode and a temperature lookup table store in the memory. A serial interface enables a host device to read from and write to locations within the memory. The invention also controls the reverse-bias voltage of an avalanche photodiode in a transceiver or receiver.

    摘要: A method for compensating for wavelength drift in a fiber-optic laser transmitter includes 1) controlling a temperature within the optoelectronic assembly at a defined level; 2) driving the optoelectronic assembly to emit light, wherein the emitted light has a wavelength that is within a channel of operation, the channel of operation including a range of wavelengths centered around a channel center wavelength; 3) accessing from memory within the optoelectronic assembly a control value associated with the temperature of the optoelectronic assembly at defined points within an operational lifetime of the optoelectronic assembly; and 4) recalculating the defined level by reference to the control value, whereby a wavelength of the optoelectronic assembly is maintained within the channel of operation despite an expected drift of wavelength.
