A communication device and a communication method eliminating clock errors are provided. Clock signals having the same frequency are used for specific consecutive circuits in a communication device in which two or more types of clock signals are used together. Preferably, the specific circuits includes: a reception function unit adapted to receive and transmit specific signals; an MPCP function unit adapted to output MPCP frames after assigning LLIDs for identifying ONUs; a signal selection unit adapted to convert an output signal from the reception function unit and an output signal from the MPCP function unit into a single output signal; a branch function unit adapted to branch the specific signals; and a first and second transmission function unit adapted to transmit the specific signals.
