TRANS PACIFIC CABLE 1 On 18 June 1964 the first trans Pacific telephone cable was completed. The 5282 nm section from Hawaii to Japan, via Midway, Wake and Guam, was laid by CS Long Lines during the first five months of that year. At Hawaii it linked up with COMPAC and HAW 1.
The cable was manufactured by Standard Telephone and Cables Ltd., England, Western Electric, USA, and the Ocean Cable Company, Japan, to the lightweight cable design developed by the British Post Office in 1951 but not placed in service until CANTAT 1 in 1961. The manufacture of this cable can be seen in the film on CS Long Lines on this page. Lightweight cable had a stranded steel core for mechanical strength, surrounded by a copper conductor layer. The outer cable sheath for the deep-sea section could then be a plastic jacket instead of the traditional heavy steel armouring wires. TPC-1 used 276 repeaters manufactured by Western Electric and operated at 384 kHz, providing 128 telephone circuits Withdrawn from service in 1990, TPC-1 was subsequently used for scientific research on earthquake detection. In 1964 Japan issued commemorative stamps to mark the laying of the cable:
