FIBER SENSING (DAS)

Get to know OptoDAS, ASN’s fiber optic sensing technology.

Distributed Acoustic Sensing (DAS) is revolutionizing subsea environmental studies by turning any fiber optic cable into a very long and highly sensitive acoustic antenna. This antenna will also support protection of the submarine cables and other critical subsea infrastructure.
With its unique interrogation technique, OptoDAS is leading the field and provides a top-range tool to scientists & operators alike.

SERVICES

Operating and maintaining submarine cable networks present unique challenges associated with accessibility, long distances, and constant exposure to the elements. Combined with the growing global internet demand, evolving technology, and regular installation of new systems, the Business Unit Services plays a key role within ASN, with an excellent level of expertise and continuously progressing experience.

From Provisional Acceptance throughout the network life cycle, the BU provides unique services designed and delivered by ASN Technical Support Engineers, covering all aspects of operations and maintenance, on land and at sea.
