Context
Yes, the internet is overwhelmingly connected by undersea cables. In fact, approximately 99% of global internet traffic is transmitted through undersea cables, which form the essential infrastructure that powers much of the world’s digital communication. These cables are the backbone of the internet, allowing for high-speed, reliable connections between continents and countries. In this article, we will explore how these undersea cables work, their importance to global connectivity, and the proportion of internet traffic they support. Also read: What are undersea cables?

Analysis
Undersea cables, also known as submarine cables, are an integral part of the global telecommunications infrastructure. These fibre-optic cables are laid across the ocean floor, connecting continents and enabling the swift transmission of data. The majority of the world’s internet traffic—around 99%—flows through these cables. In fact, without these cables, the high-speed, low-latency internet services that we rely on every day would not be possible. The internet itself is a vast network of interconnected devices, data centres, and systems. These systems rely on physical infrastructure like undersea cables to link different regions and support the massive flow of data. While satellite communication does play a role in internet connectivity, it is limited by higher latency and lower bandwidth. In contrast, undersea cables offer far greater capacity, lower latency, and more stable connections for international data transfer. The internet’s connection via undersea cables is based on fibre-optic technology, which uses light signals to transmit data. These fibre-optic cables are made of glass or plastic fibres that carry data as light pulses . The core of each cable is surrounded by several layers of protection, including copper or aluminium wire for strength, and waterproof coatings to safeguard against the harsh conditions of the deep ocean. Each undersea cable contains multiple optical fibres bundled together. When data is transmitted, it is encoded into light pulses, which travel along these fibres at high speeds. The speed of light transmission allows for incredibly fast data transfer, making fibre-optic cables an ideal choice for long-distance communication. As a result, these cables can carry massive amounts of data, supporting services such as video streaming, online gaming, social media, and cloud computing, all of which require fast, uninterrupted connections.
Key Points
- Undersea cables carry 99% of international internet traffic, making them vital for global connectivity.
- Fibre-optic technology enables these cables to transmit data quickly, with minimal loss over long distances.
