description: The paper considers methods that allow averaging the signals of an intermode fiber interferometer, namely, ensemble averaging and long implementation averaging. The aim of the work was to obtain a stable response, which can be achieved by averaging the signals of a fiber interferometer, changing the length of the optical fiber. In the course of the work, the amplitude characteristics necessary to describe the processes in the interferometer were modeled, which depend on many components: the number of modes that were excited in the optical fiber, the length of the optical fiber, the profile of the refractive index, the change in the length of the MMF under external influence on it. It has been shown that the use of methods of averaging signals over an ensemble and a long implementation allows to achieve the stability of the response under external influence. The results obtained during the work allow us to evaluate the properties of the intermode interferometer.
