Lander Lab: Selection Criteria for Underwater Cable and Connectors
field serviceable? What level of technician skill is necessary?Avoid dissimilar materials between the bulkhead connector and the housing that will lead to galvanic corrosion or cathodic delamination.Are there any Mil Spec Requirements to be met?Are there any other special requirements to be met (i.e., fiber optic, neutrally buoyant, Fluid filled/pressure balanced)?What is the cable type to be wired and bonded to the connectors (i.e., twisted single pair, parallel bundle, coaxial, electromechanical)? What is the jacket material, construction, and fillers? Is it suitable for overmolding?Is the instrument
Upscaling Power Subsea: Cables and Connectors
and HV connectors for production and processing are also under development.Demand for greater subsea connectivity is pushing the cable and connector market forward. Hardisty says big data is being utilized subsea to improve well efficiency and economic performance. This trend requires ethernet and fiber optic products. “Recently, we completed a project that involved installing a fiber optic subsea network to facilitate communication between onshore locations and multiple offshore oil and gas production units.”There is also a transition towards all-electric trees. Siemens Energy has introduced
SubCom Deploys One Million Kilometers of Subsea Cable Systems Globally
;s industry-first achievement.SubCom, whose origins date back to the mid-1800s, has been a global leader in subsea cable design, manufacturing, and deployment since its entry into the communications industry in 1955. INearly all of the world’s data is transmitted via secure, high-speed fiber optic cables that connect continents and propel the global economy. No company on the planet has deployed more cable and system components than SubCom—enough to circle the Earth more than 25 times.“On behalf of the entire team at SubCom, we are honored and grateful to have the opportunity
Quantum Sensing Beats GPS-Denied Navigational Challenges
Opal, is completely passive and undetectable and cannot be jammed or spoofed by known conventional techniques. It combines in-house-developed hardware and various software-level innovations. Key is the inclusion of a quantum magnetometer along with classical inertial navigation hardware such as a fiber-optic gyroscope. These sensors detect tiny, otherwise imperceptible signals arising from Earth’s structure that serve as magnetic “landmarks” for navigation. Only quantum sensors provide the sensitivity and stability needed to continuously “see” these landmarks from

Grander Canyons
this year, scientists at MBARI developed a new investigative technology, Geo-Sense, a new portable instrument that uses distributed acoustic sensing (DAS) technology for long-term, high-resolution monitoring of geological processes in canyons. DAS involves sending ultrashort pulses of laser light down a fiber-optic cable and analyzing millions of tiny reflections (backscatter) to essentially convert the cable into a motion sensor. The technology can track seafloor processes over long distances and in high resolution.In the latest issue of Marine Technology Reporter magazine, Celia Konowe talks to Dr Meg
Prysmian, Relativity Networks to Produce Next-Gen Cables for Data Centers
fiber technology, meeting the growing demands of data centers worldwide.In addition, Relativity Networks will provide connectors and hardware that ensure compatibility with existing fiber-optic interfaces.“Prysmian has long been a global champion in setting the standard in the field of fiber optics, and our cutting-edge solutions are always evolving to meet the demands of our customers. “This, combined with Relativity Networks’ technology, will enable both our companies to lead the global market for hollow-core fiber well into the future - a hugely significant area of focus
Turbidity Currents and Their Effects on Subsea Fibre Optic Cables
though not exclusively those offshore of large rivers such as the Congo Canyon in West Africa due to the increased sediment supply. Even flows that originate outside the canyons will often be ‘captured’ by them as they descend the continental slope.Turbidity currents can be a key risk for fiber optic cables through three main mechanisms. Firstly, close to their source, turbidity currents are erosive. As they move across the seabed, the currents dig into it and entrain more sediment into the flow. This can expose a buried cable to damage from other sources or from the other mechanisms by which
