High-Capacity Submarine Telephone Cables
Implications for Communication Satellite Research and Development
An assessment of the implications of transistorized cables for communication satellite research and development. The memorandum surveys the development of submarine telephone cables and then examines the assumption that satellites would be more economical than conventional communications facilities for long-distance, over-water, large-capacity circuits. It is pointed out that satellite circuits cost the same over water as over land; on the other hand, submarine cable circuits probably cost no more than land-line circuits in many areas of the world, and only twice as much in the U.S. The memorandum suggests that, initially at least, satellite R&D should be directed toward providing a few channels connecting a great many stations rather than a great many channels connecting only a few stations.
