VIAVI Distributed Acoustic Sensing (DAS) utilizes fiber optic cables to provide continuous and dynamic real-time information of vibrational disturbances occurring in the environment of your assets. Each FTH-DAS can monitor up to 50 km (single channel) and 100 km (dual channel) of optical fiber, providing characterized and prioritized information of events that could affect the efficiency of your operations. DAS gives you high confidence of ensuring optimal asset performance from day one, and reduces downtime and disruptions. Furthermore, retrospective review and trend analysis enables future optimization by identifying event characteristics before they materialize into a threat. DAS can be used independently or supplemented by VIAVI auxiliary modules to provide enhanced capabilities from event alarm management and advanced processing to networked solutions.
