Summary

Richard Campbell presents a comprehensive overview of the undersea cable network, tracing its history from early electrical and telegraph cables in the 19th century to modern fiber optic systems. He explains the technical evolution, including the transition from copper to fiber optics, the role of repeaters, and the manufacturing process of fiber optic cables. The talk covers the practical aspects of laying and maintaining cables, using the example of the Dunant cable laid by Google. Campbell also discusses the importance of undersea cables for global internet traffic, contrasting them with satellite systems like Starlink, which handle only a small fraction of data. He highlights the engineering challenges, such as armoring for different ocean conditions and the need for precise laying. The talk concludes with a look at the future of undersea cables, emphasizing their continued relevance in the digital age.
