Summary:
We propose a scheme of long-distance chaos synchronization using the hybrid amplification of erbium doped fiber amplifiers (EDFAs) and distributed fiber Raman amplifiers (DFRAs). The DFRA has a low noise figure and can help to reduce the ASE noise caused by the EDFA, and resultantly the long-distance chaos synchronization can be expected. Numerical and experimental results show that 1040-km chaos synchronization can be achieved by cascaded relay of EDFA and DFRA over eight 130-km single-span fiber. This scheme can pave the way of high-speed chaotic optical communication in the 1000-km interurban network.
