In this paper we describe the active devices and passive components used in the SG undersea cable system for the TAT-6 link between Green Hill, Rhode Island, and St. Hilaire de Riez, France. We explain reasons for component choice and present information about design, perfor mance, screening, and reliability. I. I N T R O D U C T I O NTraditionally, in high-reliability communication systems such as undersea telephone cables, well-established c o m p o n e n t a n d device d e signs a n d manufacturing processes are used. B u t with t h e development of the SG undersea cable system, this conservative a p p r o a c h has been challenged by t h e need for devices of higher performance. T h i s re q u i r e m e n t resulted, in some cases, in sophisticated device designs t h a t border on "state-of-the-art" concepts. For example, t h e increase in channel capacity or b a n d w i d t h requires high-frequency transistors in corporating design a n d processing features t h a t are relatively new. Nevertheless, new features were carefully evaluated so t h a t t h e y would meet t h e system reliability r e q u i r e m e n t s . In general, reliability is t h e governing criterion for t h e selection of c o m p o n e n t s a n d devices for t h e undersea cable system. T h i s concept a n d how it applies to passive components and active devices are covered in t h e following subsections: II, transistors; III, diodes; IV, gas tubes; V, resistors; VI, capacitors; a n d VII, inductors a n d transformers. E a c h subsection is complete for each component or device and covers: (t) choice and requirements, (ii) design a n d construction, (Hi) characterization a n d screening, a n d (iv) aging. 2405
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
