متن کاملDigitally Range-Gated Optical Frequency Domain Reflectometry
Summary: We present a new optical frequency domain reflectometry technique which permits high frequency sweep repetition rates without sacrificing range. This technique could thus be adapted for remote and distributed acoustic sensing over long
متن کاملOptical fiber ring resonator characterization by optical time-domain reflectometry.
A novel method for characterization of optical fiber resonators by an optical time-domain reflectometry (OTDR) technique is reported. This easy-to-use technique yields accurate results for cavity lengths ranging from a few meters to several kilometers. A simple relationship is established between the round-trip cavity loss and the position where the OTDR signal is maximum. The value obtained fo...
متن کاملHigh resolution optical time-domain reflectometry based on correlation utilizing an all-fiber chaotic source
We propose a high-resolution optical time domain reflectometry (OTDR) based on an all-fiber supercontinuum source. The source simply consists of a laser with moderate power and a section of fiber which has a zero dispersion wavelength near the laser’s central wavelength. Spectrum and time domain properties of the source are investigated, showing that the source has great capability in nonlinear...
متن کاملCapabilities and Limitations of Coherent Optical Frequency–domain Reflectometry
Optical time-domain reflectometry (OTDR), originally developed by Barnoski and Jensen in 1976 [1], is now a well-established tool for non-destructive characterization of optical networks and components. In general an ideal reflectometry system would have a spatial resolution high enough to locate closely separated sites of reflection within the network under test. In addition the sensitivity wo...
