Abstract
We propose a hybrid implementation of optical correlation-domain reflectometry (OCDR) and Brillouin optical correlation-domain reflectometry (BOCDR), which conventionally required independent experimental setups, enabling simultaneous measurements of the distributions of reflectivity and strain along a fiber under test. Through experimental demonstrations, we highlight the system’s capability to distinguish whether changes in reflectivity are caused by strain or temperature variations. This capability holds significant promise for expanding the applications of OCDR and BOCDR in the health diagnostics of infrastructures and fiber networks. The advantages and limitations of this hybrid system are also discussed in comparison with time-domain hybrid approaches.
期刊介绍：
Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews.
Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
