Abstract: The objective of the present invention is to quickly and precisely correct the measured value for light reception power to the actual value with few resources, by installing a correction device for a light reception power monitor for signal light in an optical module. The correction device is equipped with a correction table which is referenced when correcting the measured value for the light reception power of signal light, and in this correction table multiple correction values are stored in advance on the basis of the correspondence relationships between multiple reference values and multiple actual values. In the correction table, for segments wherein the change in the actual values with respect to the change in the measured values is small, the interval between the reference values is made smaller and more correction values are stored than for segments wherein the change in the actual values with respect to the change in the measured values is large. When an input value indicating the measured value for the light reception power of the signal light matches a reference value in the correction table, the correction device reads from the correction table the correction value corresponding to the reference value. When an input value does not match a reference value in the correction table, the correction device calculates a correction value in accordance with a prescribed calculation formula on the basis of the input value.
