Original Abstract Submitted
In order to achieve the above object, the present invention individually inputs light pulses to a first core and a second core at one end of a non-coupled multicore fiber having a connection portion, and individually acquires OTDR waveforms regarding the first core and the second core, calculates ratios between backscattering intensity regarding the first core and backscattering intensity regarding the second core, at at least two points including one point on one end side with respect to the connection portion and one point on another end side with respect to the connection portion, based on the acquired OTDR waveforms, and calculates a ratio between the calculated ratio on the one end side and the calculated ratio on the another end side.
