Transactions of the American Institute of Electrical Engineers, 1939
A METHOD of protection of submarine cables by placement “underground” was described during the process of its development in an article written for Electrical Engineering in May 1938. The work then projected has since been successfully carried out, and the first cables scheduled to be plowed under, to protect them from being fouled by fishing gear ...

Design of Submarine “Open” cables
Optical Fiber Communication Conference, 2018Digital coherent receiver and GN model moved submarine transmission systems into the era of “open cables”. This new paradigm leads to consider new parameters to design and characterize open submarine systems independently of the terminal equipment.

How and why are key Indo-Pacific states adapting respective foreign and defence policies to secure submarine cable networks amid heightened Sino-US network-based competition? States are driven to control submarine cable networks as these infrastructures transmit information between continents and islands, traverse vulnerable maritime zones, and ...

Submarine cables and cable ships
Electronics and Power, 1985Despite the proliferation of communications satellites there will always be a place for that original medium for intercontinental communication — the submarine cable.

IEEE Spectrum, 1966
Since 1900 most of our power has been supplied by alternating current, but the high-voltage electron tubes and the rectifying equipment developed during the last decade have revived our interest in direct current. Because geographical factors have made most of our present-day dc cables submarine, we find that we are beset by the same problems that were

Nature, 1930
DURING the summer of 1929 measurements were made on interference voltages received on a submarine cable in Trinity Bay, Newfoundland. The interference voltages were impressed on a vacuum tube amplifier capable of a power amplification of the order of 1015.

Abstract In the 1960s, it took a wild-eyed optimist like Alec Reeves to see a future for fiber optics in one of the toughest jobs for any cable—crossing the ocean depths to link continents. Yet by the mid-1970s, optical fibers were the last hope of salvaging an aging submarine cable industry besieged by rapid advances in satellite ...

The Loaded Submarine Telegraph Cable
Transactions of the American Institute of Electrical Engineers, 1925Witht an increase of traffic carrying capacity of 300 per cent over that of corresponding cables of the previous art, the New York-Azores permalloy-loaded cable marks a revolution in submarine cable practise. This cable represents the first practical application of inductive loading to transoceanic cables.

Picture Transmission by Submarine Cable
Transactions of the American Institute of Electrical Engineers, 1941The direct transmission of pictorial matter over transatlantic submarine cable has become practical through the development of some special types of networks and amplifiers. These are required because of the rapid increase of the circuit attenuation with frequency, and in order to override certain characteristic electrical interference to which the ...
