Signal synchronous transmission system, optical modulator synchronous drive system, signal synchronous transmission method and program thereof

摘要

It is possible to provide a signal synchronous transmission system, an optical modulator synchronous drive system, a signal synchronous transmission method, and a program thereof that can establish phase synchronization with high accuracy. Optical phase modulation circuits (26A, 26B) as one and the other transmission processing devices for transmitting a plurality of data in phase synchronization, and one and the other synchronous drive means (33A, 33B) for controlling the respective transmission operations synchronously The synchronous driving means (33A, 33B) externally input a reference clock for setting the operation timing of each optical phase modulation circuit (26A, 26B) via a predetermined path. Then, a phase interpolation circuit (42, 72) that generates a synchronization setting clock by performing phase interpolation processing of the optical phase modulation circuit (26A, 26B) based on the generated synchronization setting clock as a timing clock. Synchronization setting circuits (60, 76) for setting the timing of the data transmission operation together with the data signal for transmission.
