Annotation: The research results of the pulse shape transformation in microstructured polymer optical fiber with equivalent graded-index profile are presented. The measurements of the angle spectrum width of the output beam and attenuation coefficient have been carried out under different conditions of the fiber excitation. The results obtained allow to estimate the intermodal interaction level and determine the mode coupling length.
