Modulation-Frequency Dependence of Spatial Resolution in Optical Correlation-Domain Reflectometry
Keisuke Motoda, Takaki Kiyozumi, Yosuke Mizuno
The spatial resolution of optical correlation-domain reflectometry (OCDR) has conventionally been described by an expression that is independent of the modulation frequency ,…
Beat-spectrum design for 100-km-range optical correlation-domain reflectometry with localized 15-cm resolution
Takaki Kiyozumi, Yuta Higa, Soshi Yoshida +4
Conventional optical correlation-domain reflectometry (OCDR) based on sinusoidal frequency modulation exhibits a coupling between measurement range and spatial resolution because b…
High-Spatial-Resolution Optical Correlation-Domain Reflectometry with 100-km Measurement Range
Takaki Kiyozumi, Soshi Yoshida, Yuta Higa +4
In the maintenance of optical fiber networks, there is a growing demand for high-precision measurement of optical loss distribution and fault locations over long distances. In this…
High-resolution low-coherence Brillouin optical correlation-domain reflectometry with suppressed systematic error
Kenta Otsubo, Takaki Kiyozumi, Kohei Noda +3
We show that the systematic error unique to Brillouin optical correlation-domain reflectometry (BOCDR) can be effectively suppressed by use of low-coherence light, and demonstrate…
Observation of Rayleigh scattering by simplified optical correlation-domain reflectometry without frequency shifter
Tomoya Miyamae, Zhu Guangtao, Takaki Kiyozumi +4
We present a method for measuring the transmission loss of an optical fiber using simplified optical correlation-domain reflectometry. By intentionally lowering the spatial resolut…
