Paper Abstract

A flexible and efficient channel bandwidth assignment is highly required for next optical generation networks. Among various techniques to enhance the wavelength routing capability, wavelength conversion plays an important role on improving network reconfigurability. In this paper, we experimentally demonstrate a sub-band wavelength conversion of a wide-band optical orthogonal frequency-division multiplexing (OFDM) signal based on four-wave mixing (FWM) using high-nonlinear fiber (HNLF) to solve the spectrum conflicts in the flexible coherent optical OFDM (CO-OFDM) networks. Combining with the wavelength selective switch (WSS) in a reconfigurable optical add/drop multiplexer (ROADM), some spectrum-overlapped sub-bands are successfully relocated to ‘seamlessly’ form a new wide-band signal, which efficiently eliminates the spectrum conflicts, and achieves a good spectral efficiency.
