This review examines the most widely used fiber optic cables employed for DAS acquisition, namely Single-Mode Fiber (SMF) and Multi-Mode Fiber (MMF), with the different deployments and scopes of data used in geophysics exploration. By using both existing telecommunication networks (dark fiber) and. communication, large data transmission, optical imaging, and sensing applications. This work aimed at. Distributed acoustic sensing (DAS) is a recent technology that turns optical fibres into multisensor arrays. In the marine environment, it offers new possibilities for measuring seismic and environmental signals. While DAS can be applied to existing fibre optic cables used for communications, a. The advent of fiber optic technology in geophysics exploration has grown in its use in the exploration, production, and monitoring of subsurface environments, revolutionizing the way data are gathered and interpreted critically to speed up decision-making and reduce expense and time.
