Abstract : Up to now, the primary purpose of telecommunication operators’ extensive fiber networks is to transport data. Distributed fiber optic sensing (DFOS) has gained widespread attention in the telecommunications industry by enabling telcos’ fiber infrastructure to function as an intelligent sensing network, creating new business opportunities. This presentation will begin with an overview of the technology, followed by a discussion of requirements, use cases, recent progress and challenges.
