Abstract

In this paper we focus on the subject of signal-to-noise ratio (SNR) estimation for mode-mode fiber interferometer (MFI). The main problem of this issue is MFI signal fading which leads to unstable response and transfer function of MFI and does not allow correct SNR evaluation. To solve this problem the method of normalized averaged characteristics is developed and applied. SNR dependencies on different MFI parameters and for different cases of fiber launching conditions are calculated and analyzed.
