摘要：
In this paper, a multi-wavelength converter based on cross-phase modulation (XPM) effect in dual highly nonlinear fibers (HNLFs) for 60 Gbps non-return to zero/differential quadrature phase shift keying (NRZ/DQPSK) orthogonally modulated signal has been proposed. In the proposed wavelength converter, orthogonal modulation formats are used to enhance the spectral efficiency of system for physical layer expandability of optical network. The merit of proposed scheme is that the configuration of wavelength converter is simple and easy to implement at higher data rate. The BER performance of all converted signal is greater than or equal to 5.36 × 10–24 and spectral efficiency of designed wavelength converter is 9.75 b/s/Hz which makes the system more cost effective and expandable. In addition, the proposed multi-wavelength converter has been validated at variable HNLF parameters to achieve optimum wavelength conversion performance.
