Optical transceiver and host adapter with memory mapped monitoring circuitry

A system, comprising:

• a host device;
• an optoelectronic transceiver;
• and
• a host adapter, configured to couple the optoelectronic transceiver to the host device, the host adapter including:
• a transceiver interface for receiving from the optoelectronic transceiver digital values corresponding to operating conditions of the optoelectronic transceiver;
• memory including one or more memory arrays for storing information related to the optoelectronic transceiver, including the digital values received from the optoelectronic transceiver;
• comparison logic 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;
• and
• a host interface configured to enable a host to read from host specified locations within the memory, including the predefined flag storage locations, in accordance with commands received from the host.

A method of monitoring an optoelectronic device, comprising:

• at a host adaptor coupled to the optoelectronic device, receiving a plurality of analog signals from the optoelectronic device, the analog signals corresponding to operating conditions of the optoelectronic device, converting the received analog signals into digital values, and storing the digital values in predefined locations within the host adaptor;
• comparing the digital values with limit values to generate flag values, and storing the flag values in predefined flag locations within the host adaptor;
• and
• in accordance with instructions received from a host device, enabling the host device to read from host-specified locations within the host adaptor, including the predefined flag locations.
