The light source provides lights having a wide frequency region with a single mode optical fiber cable. The beam isolator transmits the lights provided by the light source to a single direction through the single mode optical fiber cable and blocks the transmission of the lights to an opposite direction. The optical coupler divides input lights transmitted through the optical fiber cable into two or more output light or joins two or more input lights as one output optical signal. The optical filter receives one output light from the optical coupler and use an optical fiber ferrule and transmits lights of a specific frequency by a WDM(Wavelength Division Multiplexing) and reflect the lights of a different frequency. The optical spectrometer receives the lights of the specific frequency reflected by the optical fiber bragg grating existed on the single mode optical fiber cable and the lights including optical frequency grating signals being reflected by the optical filter, thereby measuring optical spectrums of the two lights at the same time.
