The object of the present invention is to reduce the man-hours for correction of the frequency characteristic of an optical network thereby to augment the productivity. A frequency characteristic correction system for an optical network includes a plurality of optical repeaters connected in analog repeating connection to each other for transmitting an analog signal, each of which includes frequency characteristic measurement means for measuring a frequency characteristic based on a testing sine wave inputted by repeating, frequency characteristic discrimination means for comparing the frequency characteristic measured by the frequency characteristic measurement means with a reference value set in advance to discriminate whether or not the frequency Characteristic is near the reference value and generating a control signal for flattening the frequency characteristic, and frequency characteristic equalization means for flattening the frequency characteristic of the testing sine wave in response to the control signal generated by the frequency characteristic discrimination means, and correction of the frequency characteristic is performed in the entire network.
