| description | PROBLEM TO BE SOLVED: To provide an optical fiber communication system, using a wavelength converter for a broad-band transmission. SOLUTION: A transmitter 11 outputs signals, including channels λ'1,..., λ'N in a wavelength band outside the bandwidth of an intermediate optical element being a light amplifier 13. These signals are converted into corresponding wavelengths λ1,..., λN by the wavelength converter 21 through a transmission fiber 12. Next, the signals are mapped into the original channels λ'1,..., λ'N by a 2nd wavelength converter 22. The wavelength converters can be based on four-wave mixing(FWM), also uses a secondary nonlinear material, for instance, lithium niobate and can periodically poll it or can use a semiconductor light amplifier. |
