A wavelength converter and a wavelength division-multiplexing optical communication apparatus automatically generate clock signals of a specified frequency that match send/receive digital signals and regenerates timing for the send/receive digital signals. The wavelength converter includes: optical/electrical signal converters ( 2 A, 2 B) that convert input optical signals into electric digital signals; clock generator circuits ( 4 A, 4 B) that automatically identify the transmission mode for digital signals and generate phase-synchronized clocks of a specified frequency that match the signal transmission mode; timing regeneration circuits ( 6 A, 6 B) that regenerate clock timing for the digital signals based upon the phase-synchronized clocks from the clock generator circuits; and electric/optical converters ( 3 A, 3 B) that convert the digital signals from the timing regeneration circuits into optical signals of a specified wavelength.
