Pre-dispersed Mutual Phase-conjugation Scheme for Fiber-nonlinearity Mitigation in Coherent Optical Communication Systems -- Proposal and Analysis of Parallel Back-propagation Method --

Abstract (in Japanese) (See Japanese page) 
(in English) We propose and analyze an effective and practical method for mitigating signal distortion caused by fiber nonlinearity. In the proposed method, an original signal and a pre-dispersed phase-conjugated signal are simultaneously transmitted through the fiber on two polarization modes. The nonlinear distortion is generated in a back-propagation manner on the pre-dispersed phase-conjugated signal and cancels the nonlinear distortion on the original signal transmitted in parallel. Through extensive simulations, we demonstrate that the optimal power of the quadrature phase-shift keying (QPSK) signal is improved by over 7 dB in a 1,000-km-long dispersion-unmanaged link using standard single-mode fibers (SMFs) only.
