The significance of cross-phase modulation (XPM) induced intensity interference originating in a L-band erbium-doped fiber amplifiers (EDFA) was studied. Since the length of the EDF in L-band EDFA is longer than in C-band amplifiers, a larger impact of XPM induced intensity interference can be expected. Measurement of the XPM effect in L-band EDFA shows that it is larger by a factor of two than in C-band amplifiers. The system impact of XPM in the L-band EDFA is larger than that of XPM occurring in the transmission fiber. The XPM interaction responsible for intensity interference at the fiber output takes place mainly in a short section at the beginning of the fiber, where the walk-off between the interacting signals is small.
