A. The cost of a submarine cable depends on its length, how many fibres it contains and the number of channels it is intended to carry. To give you an idea, a single transatlantic cable would cost around $500m ( £307,443,000). We can carry out feasibility studies and costings for any systems you may be considering.
Submarine power cables work on voltages of 400 kV or more, often with DC because they are linking power grids that are not synchronised.Submarine communications cables now work with fibre-optics so the signals are modulated light-waves.Additional AnswerFurther to the original answer, another reason for using direct current for submarine cables is to eliminate capacitive currents that would flow if a.c. were used instead. The closeness of the submarine-cable's cores results in relatively-high levels of capacitance between each core and, with a.c., this would represent a capacitive load resulting in a continuous capacitive current along the cable. Such currents flow in all underground a.c. cables but, due to the length of most submarine cables, the capacitive current can be unnecessarily high.
Cables under oceans varies from 2 Gbit/s to 10 Tbit/s
Below 24 volts: low voltage cables are like other cables but without so much insulation. They are made of copper and insulated with pvc, usually only one layer. They are most commonly used in cars.
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.

Submarine cables are only suitable for use under water, that is what they are made for.

Sata cables usually cost around 5$ to buy, depending on it's length and the quality. Sata cables are available at various websites such as Amazon and Tomshardware.
Usually cables are frozen from lack of use. Cables (3) cost about $30 each. This plus the labor cost, depending on vehicle could be up to $300
