Submarine cable deployments over the years
Every submarine cable has a ready-for-service year: the moment it stopped being a construction project and started carrying traffic. Plotting those years shows how the industry moved in waves rather than at a steady pace.

Figures come from our own catalogue: a ready-for-service year is known for 683 systems. Cables without a recorded year are excluded, so the earliest decades are under-represented. See also the full cable catalogue, the interactive map and live network monitoring.
