01 January 1966
Describes submerged repeater developed for use on South East Asia Cable projects providing some 50 dB gain at 1164 kc/s. When used with 0.99 inch cable repeater spacing is 17.3 n. miles. System requirements covering transmission and suppervisory aspects are considered in some detail followed by description of the repeater circuits including repeater block diagram and system frequency such as amplifier gain, its stability, harmonics and noise are presented graphically. Overall estimated system noise performance for a cable 3000 n. miles long is less than 1 picowatt per kilometre including all contributing sources.
