  • The Ile de Batz has all of the normal navigation and engine systems of any large vessel, but with the addition of specialist controls shown here.

    These are separate from those used for the main navigation and cable-laying functions of the Ile de Batz, and use precision sensors and computers to calculate the strength of the sea and the wind to exactly control the ship's movement during cable deployment.

  • This is Alcatel-Lucent's Greenwich factory — the same site where part of the first transatlantic cable was built in the mid-19th century.

    These days, the factory is used to build three particular pieces of cable kit: repeaters, branching units and power feed equipment.

  • This is one of Alcatel-Lucent's repeaters, which are used to amplify the signal at various points along the cable.

    This repeater, a model from two years ago, has a throughput of around 1.5 terabits per second.
