Abstract(in English) The use of multi-core fibers (MCFs) for space-division multiplexing has a great potential for dealing with the traffic growth of the optical networks. MCFs can be basically categorized to coupled or uncoupled structures. Recently, uncoupled MCFs with more than 20 cores have been reported. In such uncoupled MCFs, reduction of inter-core crosstalk (XT) is important and consequently evaluation of the XT is needed. In this paper, we propose a new method for measuring the XT using a near-infrared camera instead of using a power meter. In our method, alignments for receiving output power from a MCF are not required. Therefore, the measurement time is expected to be shortened especially when a high-core-count MCF is measured. The experimental results show that the XT of approximately -30 dB can be evaluated by our method.
