Propagation Symmetry Enhanced Distortion Compensation by Optical Phase Conjugation via Step-Profiling Fiber Links
2022 Optical Fiber Communications Conference and Exhibition (OFC)(2022)
摘要
Fiber spans tailored with stepwise approximate decreasing dispersion and increasing nonlinearity parameters demonstrate enhanced compensation of nonlinear signal distortion by optical phase conjugation. WDM-QAM signal simulations and experiment show gaining >1.2 dB Q
