When fiber Bragg gratings (FBG) with different reflection wavelengths are connected in series, the reflection spectrum may be affected by cladding modes depending on the order in which the FBGs are connected and on which side the signal light is incident. It is analyzed and experimentally demonstrated that, in order to obtain proper reflection signals from multiple FBGs, the FBGs must be connected in order from those with shorter wavelengths to those with longer wavelengths and signal light must be incident on the shortest wavelength FBG.
