PROBLEM TO BE SOLVED: To provide an optical receiver regardless of transmitting velocity, which facilitates centralizing and making into module. SOLUTION: A transmitting velocity sensing part 300 outputs an optical sensing signal optic/electric converting an input optical signal and outputs a transmitting velocity sensing signal showing a voltage level showing the optical sensing signal transmitting velocity, a change sensing part 310 outputs a change sensing signal when changing the transmitting velocity, and a temperature sensing part 320 outputs a temperature sensing signal by sensing a temperature inside the transmitting velocity sensing part. Then, a signal reproducing part 350 reproduces optical sensing signal data and a clock by a prescribed reference clock, reproduces the optical sensing signal data and the clock on the basis of the reference clock corresponding to a clock correcting signal when receiving the clock correcting signal, and a control part 330 calculates an optical sensing signal transmitting velocity value from the transmitting velocity sensing signal voltage level when receiving the change sensing signal, calculates a temperature compensation transmitting velocity value compensating an error caused by a transmitting velocity value temperature calculated on the basis of the temperature sensing signal temperature value and outputs the clock correcting signal of the transmitting velocity value to the signal reproducing part. |
