The VIAVI Distributed Temperature and Strain Sensing (DTSS) solution uses Brillouin scattering to measure temperature and strain along a fiber optic cable. It can be deployed as a portable unit for commissioning and audits or as a rackable unit integrated with the ONMSi remote fiber test system for continuous monitoring. It offers simultaneous temperature and strain measurement using a single fiber, with a single‑ended design. The portable platform is compact, lightweight, and battery operated, while the rackable version fully supports VIAVI’s fiber monitoring capabilities. The B‑OTDR‑based system delivers reliable temperature and strain monitoring for diverse applications.
