Shrnutí:In this paper, we report a novel optical data fragmentation multipath (ODFM) scheme for coherent optical communication based on electrical signal processing in simulation. Under the control of a pseudo-random sequence (PRBS), we randomly disperse the user data and assign them to paths corresponding to different wavelengths for transmission. To reduce the hardware complexity of the system and the requirements for receiver sensitivity, we adopt binary phase shift keying (BPSK) modulation and homodyne coherent detection in the scheme. To verify the feasibility of the proposed ODFM scheme, we demonstrated an error-free transmission through 40 km fiber with 10 Gbps hopping rate and 10 Gbps data rate by the simulation tools. The proposed scheme can be widely used in the physical layer secure communication of backbone network, large-scale data transmission and physical layer encryption of free space optical (FSO) communication.
