    • An optical transceiver stores an output A/D value which is A/D-converted from reference voltage in an EEPROM as correction data in preparing the optical transceiver. The optical transceiver, receiving a request for outputting a monitored value from an external device connected therewith, calculates a variation based on difference between the output A/D value which is A/D-converted from the reference voltage at the timing when the request for outputting the monitored value is received and the correction data stored in the EEPROM. Then, the optical transceiver uses the calculated variation to convert current of light-input power which is input thereinto into voltage, amplify the voltage, and A/D-convert the voltage to thereby correct the output A/D value. The optical transceiver outputs the corrected A/D value to the connected external device as the monitored value.
    • 光收发器将在EEPROM中的参考电压进行A / D转换的输出A / D值存储在准备光收发器中作为校正数据。 从收发与外部连接的外部装置输出监视值的请求的光收发信机,根据在请求的时刻的基准电压的A / D转换后的输出A / D值之差, 输出监视值并将修正数据存储在EEPROM中。 然后,光收发器使用计算的变化将输入的光输入功率的电流转换为电压,放大电压,并对电压进行A / D转换,从而校正输出A / D值。 光收发器将校正的A / D值作为监视值输出到连接的外部设备。
