초록
The present invention provides a wavelength converting apparatus and optical cross connect system using the same. The wavelength converting apparatus includes a plurality of optical sources of fixed wavelengths, a switching means, and at least one wavelength converting means. The optical sources with fixed wavelengths provide probe beams with fixed wavelengths, the wavelength being different from each other. The switching means selects at least one beam of a wavelength corresponding to a wavelength conversion request of a transmission signal among a plurality of beams inputted from the fixed-wavelength light sources, and provides the selected beam as a probe beam. The wavelength converting means receives the transmission signal and the probe beam from the switching means, and converts a wavelength of the inputted transmission signal through cross gain modulation, cross phase modulation or optical-to-electrical-to-optical (O/E/O) conversion of the transmission signals and the probe beams.
