Abstract
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.
