Four-Wave-Mixing in Optical Soliton Communication System

摘要

Fiber Four-Wave-Mixing (FWM) in a soliton WDM communication system with cascaded lumped amplifiers is studied. The performance degradation of the middle channel caused by the crosstalk is investigated through theoretical analysis and numerical calculation. The results show that the influence of FWM on a soliton system is different from that on a conventional communication because of the dominant nonlinear feature in soliton communication systems.
