What is maximum bandwidth of twisted pair cable?
100ft
When Bangladesh first engaged with submarine cable?
Bangladesh has joined the consortium of SEA-ME-WE-4 submarine cable, which starts its commercial activities from 21st may, 2006.
How much do submarine cables cost?
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.
What is the voltage used in submarine cable?
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.
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
What is submarine cable buoy light and buoy?
what is submarine cable buoy light and shape & what is submarine emergency buoy light and shape
Does a wireless modem give you the same bandwidth as a cable modem?
In general, a cable modem will offer better and more reliable bandwidth and a wireless modem.
What is maximum bandwidth of twisted pair cable?
100ft
How does cable modem internet access relate to bandwidth?
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.
Give you some information about submarine cable?
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.
When Bangladesh first engaged with submarine cable?
Bangladesh has joined the consortium of SEA-ME-WE-4 submarine cable, which starts its commercial activities from 21st may, 2006.
What is the typical bandwidth of a channel for a cable modem?
6 MHz
Will a DSL modem have the same bandwidth as a cable modem?
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.
What is a cable ship?
A cable ship is a vessel fitted for laying and repairing submarine cables.
Is the submarine cable is suitable for under water?
Submarine cables are only suitable for use under water, that is what they are made for.
Which of the following influence the bandwidth of a coaxial cable?
The length of the cable, the gauge of the inner conductor, the material used as dieletric.
What is a cablegram?
A cablegram is a telegram transmitted via a submarine cable.
