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 method of maintaining desirable optical performance of an optoelectronic apparatus at extreme temperatures is disclosed. At a first temperature, a first bias current at which the laser generates optical signals at a first level is determined. At a second temperature outside of a predefined range of the first temperature, a second bias current at which the laser generates optical signals at a second level is determined. If the second temperature is greater than the higher end-point temperature of the predefined range, the second predefined level is defined to be less than the first predefined level. If the second temperature is less than the lower end-point temperature of the predefined range, the second predefined range is defined to be greater than the first predefined level.

摘要： This disclosure concerns methods for calibrating optical emitters. For example, one calibration method is employed in connection with an optical transceiver that includes a laser. A range of temperatures is defined that includes low end and high end temperatures. At a first temperature, within the range, a first bias current to the laser is adjusted until the laser generates an optical signal at a first predefined power level. At a second temperature outside the range, a second bias current to the laser is adjusted until the laser generates an optical signal at a second predefined power level. If the second temperature is greater than the high end temperature, the second predefined power level is defined as less than the first predefined power level, and if the second temperature is less than the low end temperature, the second predefined power level is defined as greater than the first predefined power level.
