We have greatly increased the dynamic range of a synchronous multi-channel OTDR system for the mode coupling measurement of a multi-core fiber (MCF) by more than 20 dB by introducing an optical amplifier and an optical masking apparatus. We used the OTDR system to measure the mode coupling along 10 km-long MCFs with low crosstalks of less than -50 dB. Thus, we successfully measured the fiber structural irregularity dependence of mode coupling along the MCF.
