What is power feeding equipment?
Power Feeding Equipment (PFE) provides constant current to energize submerged equipment to ensure long-term stable operation of the submarine system. PFE 1670 pushes the industry power feeding limits, provides the possibility for longer-distance transoceanic transmission.
Why submarine cables are used?
New Delhi, Aug 10: 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.
How submarine cables are installed?
Submarine cables are laid down by using specially-modified ships that carry the submarine cable on board and slowly lay it out on the seabed as per the plans given by the cable operator. The ships can carry with them up to 2,000km-length of cable. Newer ships and ploughs now do about 200km of cable laying per day.
What is submarine cable landing station?

Who manufactures undersea?
Submarine Cable Products for Oil and Gas Industry General Cable has been manufacturing underwater cables since 1899, when NSW began operations in Germany. General Cable is one of the world’s leading names of submarine power and telecommunication cable systems as well as for offshore and special cables.
How does a submarine cable work?
How do cables work? Modern submarine cables use fiber-optic technology. Lasers on one end fire at extremely rapid rates down thin glass fibers to receptors at the other end of the cable. These glass fibers are wrapped in layers of plastic (and sometimes steel wire) for protection.
What is PFE in cable landing station?
PFE is for supplying power to system components and repeaters. In the international submarine cable system, each landing station is equipped with PFE for the repeater, branch unit, equalizer, and other sea equipment to provide a stable DC voltage.
Where does India get internet?
As of May 2014, the Internet is delivered to India mainly by 9 different undersea fibres, including SEA-ME-WE 3, Bay of Bengal Gateway and Europe India Gateway, arriving at 5 different landing points. India also has one overland internet connection, at the city of Agartala near the border with Bangladesh.
