The VIAVI OneAdvisor 800 DTS is a distributed fiber‑optic sensing solution that measures temperature using single‑ended Raman OTDR technology. Built on over 40 years of fiber‑optic testing expertise, it brings advanced DTS capabilities to field and monitoring applications. The system features dual‑wavelength measurements for automatic temperature calibration and requires only one fiber for both DTS and OTDR functions. Designed for efficient remote operation with minimal training, it is portable, lightweight, battery‑powered, and compatible with VIAVI’s ONMSi monitoring platform for rack‑mounted, multi‑port measurements.
