TeleGeography Explains the Internet

In our final episode of this special podcast series about undersea cables, we're exploring the rapidly evolving technology of using fiber optic cables as remote sensors. We welcome Mark Englund, CEO of Fibersense. Mark explains the fascinating world of Distributed Acoustic Sensing (DAS), and how this emerging technology is turning existing fiber optic cables into sentient, continuous sensors. We explore: How this is transforming the cable industry, providing unparalleled real-time protection by detecting anchors and fishing gear and other potential threats. How Fibersense uses machine learning to cut through the ocean's "cacophony" and make the data actionable for cable operators. Finally, we spend a little time looking beyond the subsea, exploring the immense potential of DAS for terrestrial fiber in applications like protection against excavators, water leak detection in city infrastructure, and even a new vision for traffic safety and autonomous.   Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast TeleGeography Blog: https://blog.telegeography.com/ Our Research: https://www2.telegeography.com/en/our-research

Where do operators physically place their submarine cables, and why does that matter? Even among those familiar with the undersea cable market, many don't give much thought to where precisely the cables lie on the seafloor and what factors determine this geography. Today's guest knows a thing or two about how it gets done. We welcome James Porter, Cable Route Engineer at Alcatel Submarine Networks (ASN). James spends his days studying maps to route submarine cables, ensuring ease of maintenance and compliance with guidelines. He joins Greg to discuss the challenges of seabed congestion, particularly in deep-water areas where new cables must be laid at a safe distance from existing ones to ensure they can be repaired in the future. The pair also discuss: The role of the International Cable Protection Committee (ICPC) and its recommendations for planning new cables to avoid impacting existing systems. The complexities of geopolitics and physical geography, which often restrict cable routes and force them into congested choke points. The critical need for better communication and data sharing among industry players to more efficiently and safely manage the crowded seabed. 🎧 Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast 💻 TeleGeography Blog: https://blog.telegeography.com/ 📊 Our Research: https://www2.telegeography.com/en/our-research  

When submarine cables hit the mainstream media, it might be because something has gone wrong. Especially when faults lead to a bottleneck that slows down or, in rare cases, even stops internet traffic for some people. Our guests today presented a paper at SubOptic 25 detailing their study on global submarine cable maintenance and recommendations for the industry. Mike Constable, Principal at Infra-Analytics, and Alan Mauldin, Research Director here at TeleGeography, joined the pod to discuss their review of cable faults and the readiness of the industry to fix problems over the coming years.   🎧 Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast 💻 TeleGeography Blog: https://blog.telegeography.com/ 📊 Our Research: https://www2.telegeography.com/en/our-research 

Let's talk about keeping submarine cables secure. Ferris Adi, Chief Information Security Officer at Trans Americas Fiber System (https://transamericasfiber.com/), joins to discuss specific threats to submarine cables and how best to build resiliency against them. We also cover various regulatory and compliance issues that submarine cable operators face when landing in different countries, as well as geopolitical threats to cable systems. 🎧 Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast 💻 TeleGeography Blog: https://blog.telegeography.com/ 📊 Our Research: https://www2.telegeography.com/en/our-research 

We're kicking off a brand new mini-series all about *submarine cables.* To start off the series, we couldn't think of a better guest than Senior Research Analyst Lane Burdette, an expert (and nerd) when it comes to cables. She and host Greg Bryan discuss the economics of submarine cables. The conversation covers: A refresher on the cables themselves, and all of the components that go into building them and lighting them for data transmission service. The costs of these elements and how to construct the costs of building a sub cable. Who builds these cables and why, and then how cable builders make money on their investment through selling data transmission services, as well as how and why sub cable prices vary around the world. How supply and demand are likely to develop in this vast undersea market, and what Lane sees for the future of cable profitability. 🎧 Podcast HQ: https://www2.telegeography.com/telegeography-explains-the-internet-podcast 💻 TeleGeography Blog: https://blog.telegeography.com/ 📊 Our Research: https://www2.telegeography.com/en/our-research
