Each of the transatlantic cables will be laid in three segments. The shore end is to be played out between Clarenville, Newfoundland, Newfound-land, and the edge of the Continental Contin-ental Shelf, a distance of about 200 miles. The second segment, of lighter design, - will extend the cable to some 500 miles off Scotland. The third and final section will bridge the remaining distance to Oban, Scotland. Shallow water sections at each end require much heavier armor as protection against the action of the sea and shipping. Telephone scientists have spent many years developing the amplifiers ampli-fiers needed to make these deep-sea deep-sea voice cables operatable. The amplifiers were designed to meet three specifications: 1. They had to withstand enormous enor-mous pressures at the ocean floor that sometimes reach three tons per square inch. 2. They had to be built into the cable and still be slim enough to pass through the ship's laying gear. 3. They have to operate for many years without attention. |
