By any measure, the global bandwidth market is thriving. International bandwidth demand has nearly doubled from 2020 to 2022, and has now reached 3.8 Pbps.

Meanwhile, the lit capacity on major submarine cable routes continues to soar, keeping pace with demand.

How? Is the network getting faster?

Not quite. Think bigger highway, not faster cars.

To meet demand, submarine cable operators are lighting additional capacity on existing systems. Not only that, but new systems are coming online across all routes.

The year 2016 initiated a period of significant global investment in the sector. Cables with a combined construction cost of $8.7 billion entered service between 2018 and 2022, and every major subsea route saw new cables deployed during this timeframe.

Investment is expected to surge across all global routes.

Investment is expected to surge across all global routes. Based on publicly-announced planned cables, over $10 billion worth of new cables are expected to enter service between 2023 and 2025.
