چکیده
We propose a newly configured optical correlation-domain reflectometry (OCDR) without the use of an electrical spectrum analyzer (ESA) for high-speed distributed reflectivity measurement with enhanced spatial resolution. First, operation ESA-free OCDR is analyzed by numerical simulation, results which show potential configuration to perform improved Subsequently, simulation are verified comparison experiments, where measurements along 32-m-long single-mode fiber joint multiple connectors performed using both conventional (with averaging) and configurations (without at repetition rate 100 Hz. The widths peaks experimentally obtained 22.9 cm 7.0 cm, respectively. Finally, we evaluated performance higher rates, achieving 6.3-cm resolution 1 kHz. This result indicates that can speed than ever.

The optical spectrum measurement is indispensable to the wavelength division multiplexing (WDM) technology that is increasingly being used in optical communications. Optical spectrum analyzers, which measure and analyze the optical spectrum of light that travels through optical fibers, are required to have high performance, functionality, and throughput as sophisticated optical communication de...
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...
