摘要
Abstract
Aiming at the fluctuation problem of the signals phase in microwave fiber-optic system affected by the tempera-ture change of optical fiber,an information processing module is designed to control tunable phase shifter for precise phase com-pensation. Thus the phase-stable transmission of microwave signals is achieved by using the principles of vector sum to detect a phase deviation of the microwave signal. Based on the theoretical model,the influence of temperature variation on the phase in-formation of microwave optical link is experimented and tested,and the microwave phase-stable optical transmission system is structured. 10GHz microwave signals are transmitted with 25km standard single-mode fiber for a long time,the test result show that the phase fluctuations is stable controlled within ± 2°,thus the feasibility of the scheme is demonstrated.关键词
