The millions of kilometers of fiber optic cable lying on the ocean floor have traditionally been invisible assets—laid once and forgotten until something breaks. But Distributed Acoustic Sensing (DAS) technology is transforming this dark infrastructure into a vast network of intelligent sensors capable of detecting everything from anchor drags to earthquakes.
The internet depends on a network of submarine cables no thicker than a garden hose, yet these tiny conduits carry the vast majority of global internet traffic. As digital demand explodes and new cables proliferate, cable route engineers face an increasingly complex challenge: finding space on the seafloor for new systems while maintaining the safety and reliability of existing infrastructure.
Submarine cables carry over 99% of international data traffic and face unprecedented cybersecurity challenges that extend far beyond traditional network security.
In this episode of the TeleGeography Explains the Internet podcast, Ferris Adi, Chief Information Security Officer at Trans Americas Fiber System, recently shared insights on the evolving threat landscape and strategic approaches to protecting these vital assets.
How AI will impact enterprise networks is a huge topic that we're tackling in a multi-part series. In these posts, we're comparing the total cost of ownership (TCO) of a legacy MPLS network—one that still represents many multinationals’ WANs in 2025—to various hybrid or internet-first alternatives designed to accommodate changes brought by AI and cloud.
Predicting the future is hard.
As an analyst, that is exactly what people hope I can do. Of course, no one can predict the future, but we can model various outcomes given the best data we have on hand.
So using the data, let's make a prediction about the future impact of AI on enterprise networks.
In this episode of the TeleGeography Explains the Internet podcast, FCC Commissioner Nathan Simington joins the show for a deep dive into the evolving world of spectrum allocation, broadband infrastructure, submarine cable policy, and cybersecurity. With a unique background in finance, law, and policy, Simington offers an interesting perspective on the complexities of the current telecom environment and where federal policy is headed.
Today on TeleGeography Explains the Internet, we welcome Michael Martin, formerly a global network and security architect at McKinsey.
Michael has extensive experience and knowledge in the enterprise network space. I wanted to get his take on the industry's state of implementation of network automation among enterprises.
