The invention relates to an optical time-diversion multiplexing device based on an aperture limited time lens and belongs to the technical field of high-speed optical communication. The optical time-diversion multiplexing device comprises a polarization controller, a phase modulator, a dispersive medium unit, an intensity modulator, a dispersion compensation unit, a frame clock source, a power divider, two phase shifters and two power amplifiers, wherein the polarization controller, the phase modulator, the dispersive medium unit, the intensity modulator and the dispersion compensation unit are sequentially and optically connected, the frame clock source, the first phase shifter, the power divider and the second phase shifter are sequentially connected, the input end of the first power amplifier and the input end of the second power amplifier are connected with the output end of the power divider and the output end of the second phase shifter respectively, and the output end of the first power amplifier and the output end of the second power amplifier are connected with the phase modulator and the intensity modulator respectively. The optical time-diversion multiplexing device based on the aperture limited time lens has the advantages of being simple in structure, stable in performance and low in power penalty.

The invention discloses a method and a system of data synchronism in a business service. The method includes: step one, a main data module is called by a main business module to carry out data operation; step two, after the main data module carries out the data operation, if the data operation is finished successfully, step three is performed, otherwise, the data operation is in rollback, and data operation failure is replied to the main business module; step three, the main data module transmits data operation requirements to a backup data module, the backup data module carries out the data operation according to the requirements, if the data operation is finished successfully, step four is performed, and otherwise, step five is performed; step four, the backup data module replies data operation success to the main data module, and the main data module replies the data operation success to the main business module; and step five, the data operation is rolled back by the backup data module, the data operation failure is replied to the main data module, the data operation is rolled back by the main data module, and the operation failure is replied to the main business module. According to the method and the system of the data synchronism in the business service, the problem that the data synchronism is not controlled by the business service is solved.
