Abstract: A control method of an integrated facility safety control system predicts short-term safety of a facility by using an artificial intelligence (AI) model embedded in an intelligent edge interrogator and predicts long-term safety of the facility on the basis of long-term sensing data received from the intelligent edge interrogator by using an AI model embedded in a server. Accordingly, a server and an intelligent edge interrogator may divisionally perform an analysis operation on the short-term safety and long-term safety of facility on the basis of data collected from an optical fiber sensor, and thus, may solve a load of data concentrating on a server, a problem of computing power, and a network problem caused by massive data transmission.

Abstract: Disclosed is an optical device. The optical device includes: a first WDM filter for dividing an optical signal transmitted through and reflected from a measured subject into an optical signal of an infrared band and a first optical signal through wavelength division multiplexing; a first LC tunable wavelength filter disposed at an output end of the first WDM filter, and selectively filtering the optical signal of the infrared band; a second WDM filter for dividing the first optical signal into an optical signal of a first visible light band and a second optical signal through wavelength division multiplexing; and a second LC tunable wavelength filter disposed at an output end of the second WDM filter, and selectively filtering the optical signal of the first visible light band.

Abstract: Disclosed is a variable optical attenuator. The variable optical attenuator includes an electrochromic device having a reflective property or a transflective property, a lens configured to convert input light to focused light or collimated light and input the focused light or the collimated light to the electrochromic device, and an outputter configured to output light reflected from the electrochromic device, in which the electrochromic device is configured to attenuate an intensity of the input light by controlling a reflectivity and a transmissivity of the input light based on an element included in the electrochromic device and a voltage to be applied to the electrochromic device.
