[VARIOUS AUTHORS].

SD Submarine Cable System. [11 papers, see below].

(New York), American Telephone and Telegraph Company, 1964. 8vo. Volume XLIII, September, No. 4, Part 1 and 2, 1964 of "The Bell System Technical Journal". In the original printed blue wrappers. Previous owner's stamp to front wrapper, and very light brownspotting to spine, otherwise a near mint copy. Pp. 1155-1479 + two folded plates, one loosely inserted.

First publication of AT&T's first submarine telephone cable across the pacific. It went from Japan to Hawaii, where it connected to two cables linking Hawaii with the mainland. This brought the same improvements to trans-Pacific service that the TAT-1 had brought to trans-Atlantic service in 1956. (See link below).
Since the trans-Atlantic service opened in 1927, calls had traveled across the ocean via radio waves. But cables provide much higher signal quality, avoid atmospheric interference and offer greater capacity and security.

Due to uncertainties in global politics, the economic involvement by the US government in the project was minimal.
