Disclosed is a bit-rate-independent optical receiver capable of easily achieving centralization and modulization thereof. The bit-rate-independent optical receiver includes: a bit rate sensing unit for outputting a photosensitive signal optoelectrically converted from an input optical signal, while outputting a bit rate sensing signal with a voltage level indicative of the bit rate of the photosensitive signal; a variation sensing unit for outputting a variation sensing signal when the variation in the bit rate occurs; a temperature sensing unit for sensing the internal temperature of the bit rate sensing unit and outputting a temperature sensing signal indicative of the sensed internal temperature; a signal reproducing unit for reproducing the data and clocks of the photosensitive signal based on a predetermined reference clock while, in response to the reception of a clock correction signal, reproducing the data and clocks of the photosensitive signal based on a reference clock corresponding to the clock correction signal; and, a control unit for calculating the bit rate of the photosensitive signal based on the voltage level of the bit rate sensing signal in response to a reception of the variation sensing signal, compensating the calculated bit rate for errors resulting from a variation in temperature based on the temperature indicated by the temperature sensing signal, and outputting a clock correction signal indicative of the temperature-compensated bit rate to the signal reproducing unit.
