Wavelength converter and optical cross-connect system using the same

摘要

This invention provides a wavelength converter and an optical cross-connect system using the same. The inventive system enables one multi-wavelength light source to provide each wavelength converter with the necessary tuned wavelength, without using individual light sources with different wavelengths for each wavelength of a multiplexer. The wavelength converter converts the input multi-channel optical signals into wavelengths used for a subsequent transmission. A wavelength division multiplexer is provided to divide all input optical signals connected to the output link into wavelength units, or collects the divided wavelength-unit optical signals. Meanwhile, a multi-wavelength light source generates a multi-wavelength optical signal, which is applied to and de-multiplexed by the wavelength division multiplexer, and then adapted as a tuned wavelength for wavelength conversion of each channel optical signal.
