Abstract:
The present invention relates to a distributed sensing optical fiber performance multi-objective multi-degree-of-freedom static and dynamic test integrated platform and a test method. Wherein an optical fiber multi-degree-of-freedom fixing system is sequentially connected with an artificial loading and unloading device and an oil pressure control loading and unloading device, and an optical fiber under test is connected with the optical fiber multi-degree-of-freedom fixing system and a distributed optical fiber Brillouin frequency shift acquisition system; and test on performance of optical fiber is achieved by controlling devices in the optical fiber multi-degree-of-freedom fixing system. The device of the present invention has a large number of advantages such as a simple structure, a low cost, convenient operation, less disturbance, many test classes, strong adaptability, stable performance and convenient loading and unloading.
