Repeater Design for the Newfoundland-Nova Scotia Link
Le résumé fourni par la source
The Newfoundland-Nova Scotia cable required the provision of 16 submerged repeaters each transmitting 60 circuits in the bands 20–260 kc from Newfoundland to Nova Scotia and 312–552 kc in the opposite direction. The paper deals with the design and production of these repeaters. Each repeater has a gain of 60 db at 552 kc, and the amplifier consists of two forward amplifying paths with a common feedback network. Reliability is of paramount importance, and production was carried out in an air-conditioned building with meticulous attention to cleanliness and to very rigid manufacturing and testing specifications. The electrical unit is contained in a rigid pressure housing 9 feet long and 10 inches in diameter with the sea cables connected to an armor clamp and a cable gland at each end. A submerged equalizer was provided near the middle of the sea crossing.
