A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea.
Application:
* Submarine Composite Power Cables - land, offshore wind farms, offshore oil and gas installations
* Umbilicals - interconnecting / connecting subsea installations to fixed, floating platforms, FPSOs
* Fibre Optic Cables - power and signal feeding subsea installations, scientific sensors, seismic arrays, etc
* ROV Control Cables - ROVs and trenchers, dynamic applications down to 7,000 meters
