Abstract :
We experimentally demonstrate a sub-band wavelength conversion scheme based on four-wave mixing in high-nonlinear fiber for multiple Tb/s-class superchannel coherent optical orthogonal frequency-division multiplexing networks. Combined with the wavelength selective switches in reconfigurable optical add/drop multiplexers, the overlapped spectra are efficiently relocated and almost seamlessly formed into a new superchannel with very little spectral efficiency degradation.
