Embodiment Construction

[0035] See figure 1 , figure 2 , image 3 It can be seen that the secure optical communication system is composed of an optical signal transmitting part 1, an optical signal encryption part 2, an optical signal transmission part 3, an optical signal decryption part 4, and an optical signal receiving part 5. Among them, the optical transmitting part 1, the optical signal transmission part 3, and the optical receiving part 5 are basically the same as the normal optical communication system. The difference is that the optical signal encryption part is added; the encryption part dynamically increases the transmitted optical pulses. Intensity broadening and deformation; an optical signal decryption part is added, which performs precise synchronous dynamic dispersion compensation on the transmitted optical pulse according to the key information passed from the key channel, so as to restore the signal.

[0036] The optical signal encryption part 2 is composed of a fixed dispersion modul...

Abstract

The invention discloses a secret optical communication system based on dynamic strong dispersion management, belonging to the technical field of secret communication, and comprising an optical signal emission part, an optical signal encryption part, an optical signal transmission part, an optical signal receiving part and an optical signal decryption part; the optical signal encryption part is provided with a fixed and adjustable dispersion module; the optical signal decryption part is provided with a fixed and adjustable dispersion compensation module; the dispersion module and the dispersion compensation module are formed by any one of a fiber bragg grating, a G-T etalon, an MEMS (Micro-Electromechanical System), a PLC (Programmable Logic Controller) annular resonant cavity; one end of the optical signal encryption part is connected to an optical signal transmitter, and the other end of the optical signal encryption part is connected to the optical signal transmission part; secret keys are transmitted to the optical signal decryption part through key secrete channels; one end of the optical signal decryption part is connected to the optical signal transmission part, and the other end of the optical signal decryption part is connected to an optical signal receiver; and the optical signal decryption part carries out real-time, synchronous and precise compensation on the transmitted optical pulse according to information provided by the secrete keys for releasing signals. In the secret communication, a dynamic dispersion management technology is used in the optical communication system for the first time to realize the secret transmission of information.

Description

Technical field [0001] The invention relates to the technical field of secure communication, in particular to a secure optical communication system based on dynamic strong dispersion management. Background technique [0002] There are currently three main types of optical fiber secure transmission communication methods: Optical Code Division Multiplexing Access (Optical Code Division Multiplexing Access) system; Quantum Private Communication (Quantum Private Communication), and Chaotic Secure Communication (Chaotic Secure Communication). [0003] Different from the above method, the present invention is based on the principle of dispersion effect and adopts a dynamic strong dispersion management scheme. Strong dispersion management is currently used in high-speed quasi-linear systems to improve the transmission quality of optical communication systems, but has not been used in secure communications. E.g: [0004] References (1) R.-J Essiambre, G. Raybon, and B. Mikkelsen, "Pseudo-L...
