Theoretic Analysis and Simulation of Crosstalks in Time Divison Multiplexing of Fiber-optic Hydrophones

Crosstalk is one of many puzzles that baffled the application to time-division multiplexing(TDM) technology for fiber-optic hydrophone array.The crosstalks between the channels of TDM were theoretically analyzed,and the simulation technique was used to investigate the relation of crosstalk to such factors as the extinction ratio of optical switch and the channels multiplexed in the TDM array.
