Long‐distance submarine cable transmission systems require precise, highly reliable repeaters for amplification, and adjustable equalizers for reducing accumulated transmission deviations. This article describes the problems and solutions in designing suitable repeaters and equalizers for the high capacity SF System. This system uses a repeater with transistors to provide a capacity of 800‐message circuits.

SF System: Manufacture of Submarine Cable Repeaters and Ocean Block Equalizers

Chapman¹

1970

In this article we describe the facilities and procedures used to manufacture SF repeaters and equalizers. Careful selection and training of production and inspection personnel play a vital role in achieving the desired standards in qualifying material and for assembly and test of units. Detailed engineering planning provides the best environmental conditions and manufacturing facilities and processes. Close collaboration by the manufacturer with Bell Telephone Laboratories during product design and specification and during manufacture assures a tightly controlled, well understood product.
