Distributed acoustic sensing (DAS) is an emerging technology that uses submarine optical-fiber (OF) cables to monitor the sea state. Here, we present DAS-based ocean current observations when a super typhoon passed overhead. The microseismic noise induced by ocean surface gravity waves (OSGWs). The Submarine Cable Map is a free and regularly updated resource from TeleGeography. Undersea cables are the lifelines of modern economies: they carry over 95 percent of the world's internet traffic, making them one of the most critical—yet vulnerable—pieces of infrastructure in the 21st century. A far broader array of systems now covers the ocean floor – and must be protected. The headlines are. Microsoft said in a status update that the Middle East "may experience increased latency due to undersea fibre cuts in the Red Sea," but gave no other details.
[pdf] Azerbaijan and Kazakhstan have started deploying the first-ever fiber-optic cable between the countries, Kazakhtelecom CEO Bagdat Mussin announced on his Telegram channel. The cable will run along the seabed of the Caspian Sea, from the Kazakh city of Aktau to the Azerbaijani city. Trans-Caspian fiber-optic cable project due to be completed by late 2026. The. According to Yusif Jabbarov (Yusif Cabbarov), Chairman of NEQSOL Holding, the Trans-Caspian fiber-optic cable project not only strengthens digital connectivity and technological advancement across the region but also contributes to regional economic cooperation.
