FIBER SENSING (DAS)

ASN has 40 years experience in design and manufacturing of optical fiber sensing systems. OptoDAS is a highly advanced DAS interrogator recording distributed strain along optical cables induced by acoustic waves and vibrations.

The OptoDAS sensing technology is turning more than 100km length of submarine cable into an extremely sensitive acoustic antenna that can be used for a broad range of applications such like cable threat monitoring or scientific and environmental recordings.

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.

UPGRADE

Upgrading existing submarine cable systems is a highly cost-effective method of enhancing high-speed capacity. We provide the necessary technologies, tools, and teams for all aspects of these operations.
