Bangladesh has joined the consortium of SEA-ME-WE-4 submarine cable, which starts its commercial activities from 21st may, 2006.
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.
A low bandwidth signal does not have more power.

To access the internet via broadband cable, you will need a cable modem. Bandwidth is used for transmitting the signals of the internet to and from your home, and the cable modem is in place to allow the signals to be sent and received.
Modern submarine cable is all fiber-optic. It's about a foot in diameter. In it they run just a few strands of fiber optic cable. It's packed in Vaseline--seriously, that's what they use. Then it's wrapped in plastic, metal and fiberglass jackets for protection.In the cable are inline amplifiers that boost the signal.Now, in the OLD days before submarine cable went digital, each wire pair in a submarine cable carried 16 channels of communication, as opposed to 12 channels on a terrestrial link. They did it that way because submarine cable is so expensive.

The bandwidth of a DSL modem varies depending on physical distance from the main center, while a cable modem is a static speed in all areas. For this reason, distance determines the greater bandwidth size.
