A review of submarine cable communications

The submarine cable industry has just celebrated its centenary. In this paper, after brief historical references, some information on modern practice is given. It is shown that long-distance submarine cable communication has increased rather than diminished in importance as radio communication has grown up in the last 25 years or so. Great and progressive changes can be predicted for the next decade following the extended use of synthetic insulating materials and the submerged repeater. These modern developments are described in some detail, and their present effect and possibilities for the future on world communications are considered.
