Abstract

A monitoring system includes a monitoring device including an optical transmitter and an optical receiver, an optical repeater, and a first MCF transmission path and a second MCF transmission path, each of the paths includes cores, and connects the monitoring device and the optical repeater with each other via the plurality of cores, the optical transmitter generates an optical pulse, and inputs the optical pulse to a first core included in the cores of the first MCF transmission path, the optical repeater loops-back the optical pulse being received from the first core to a second core included in the cores of the second MCF transmission path, and the optical receiver receives the optical pulse being looped-back, as an optical reception pulse, from the cores of the second MCF transmission path, and calculates a corrected reception level, based on the optical reception pulse.
