Zusammenfassung:Disclosed are a distributed temperature sensing system using a multicore optical fiber and a method thereof. The distributed temperature sensing system using the multicore optical fiber is configured to use the multicore optical fiber for a typical distributed temperature sensing system (DTSS), analyze a signal by collecting, for all cores, Raman-scattered light that is backscattered by multiple cores, increase the size of the signal by the number of times corresponding to the number of cores, increase a signal-to-noise ratio (SNR) for the same sensing time, and increase a sensing distance.
