Prysmian, Relativity Networks to Produce Next-Gen Cables for Data Centers

Prysmian has entered into a long-term partnership agreement with Relativity Networks, the at-scale provider of next-generation fiber-optic technology, for volume production of the hollow-core optical fiber and cable in demand by operators of the data centers required for the AI economy.The collaboration will see Prysmian and Relativity Networks co-manufacture fiber and cable based on Relativity Networks’ patent-pending hollow-core fiber (HCF) technology, which was developed in collaboration with the College of Optics and Photonics at the University of Central Florida.Leveraging Prysmian’s

Connectors Facilitate Camera System for BBC Underwater TV Series

Teledyne Impulse-PDM supplied its Omicron optical fiber connectors to BBC Studios for use in its upcoming underwater natural history series, set to air in 2026. Filming required custom-built camera technology designed to capture extraordinary marine footage from the depths of the Arctic, facilitated by the Rev Ocean’s Aurora ROV.To capture groundbreaking underwater content BBC Studios and Marine Imagine Technologies designed a deep ocean-rated camera system integrated with a telemetry bottle, the central hub for communications on the submersible. However, during the Arctic expedition

that were necessary to enable a non-O&G company initially unfamiliar with the expectations of the O&G industry to deliver a solution that is relevant to the needs of this industry."“ASN has long-standing expertise and field proven track record on the design of long distance subsea optical fiber systems and the design, manufacture and deployment of high reliability subsea products operating up to 8000 m water depth. Under Equinor’s guidance and support, ASN has leveraged on this expertise to develop and qualify DC/FO Technology, now adopted on Equinor projects and available to

connectivity for the remote ROV piloting operations. This required a complex setup process to establish a bridge between the data networks of both companies, without compromising their respective cyber security policies. The result of the collaboration established a secure data link via subsea optical fiber to the worksite offshore," the company added.According to Oceaneering, the Stavanger-based remote piloting team operated the ROV for over 70 hours during the campaign program with 100% uptime. The implementation of this project was achieved by a global support team comprising members from

Meet NOUS: An Underwater ‘Artificial Mind’

a year later."NOUS" allows continuous (24/7) monitoring and protection of an underwater site using machine learning and image and sound processing algorithms.Briefly, it is a system consisting of an underwater array of self-cleaning cameras and microphones, which are either connected by optical fiber and electrical power conductor to the nearest shore, or to a floating platform on the sea surface. On the shore or on the platform there is a photovoltaic panel power supply and communication devices for Internet connection.On the occasion of the successful completion of the initial operation

Silixa Claims 'World's first' as it Installs Distributed Acoustic Sensing (DAS) System at BP's Gulf of Mexico Field

Optical fiber sensors provider Silixa on Wednesday announced the successful installation, validation, and borehole seismic acquisition from a permanently installed fiber-optic Distributed Acoustic Sensing (DAS) system, Carina Subsea 4D, on BP’s Atlantis Phase 3 subsea field development.The Atlantis Phase 3 development involves a new subsea production system with eight new wells tied into the current Atlantis platform, 150 miles south of New Orleans. "The engineered fibre optic system enables high-definition seismic data acquisition along the entire subsea wellbore. This allows seismic

Russia Starts Operation to Lay Undersea Fiber Optic Cable through Arctic

Arctic port towns as well as the Kamchatka peninsula and Sakhalin.Alexei Strelchenko, head of the cable-manufacturing and laying company, said it will cost 65 billion roubles ($889 million) and be financed exclusively by the state.The cable is manufactured in the Arctic city of Murmansk using Chinese optical fiber and Russian components, Strelchenko said. A vessel departed Murmansk on Thursday to begin laying it near Teriberka.The project will require additional connecting cables to link to the global communications cable network for which foreign investment would be needed, said Andrey Kuropyatnikov,
