SG undersea cable system: Repeater and equalizer design and manufacture

Linearity and reproducibility of undersea electronics play key roles in determining the achievable performance of an undersea cable system. This paper describes the characteristics of undersea electronics and the measures taken in design and manufacture to achieve the desired performance and reliability, giving special emphasis to new features and applications. It describes in detail the performance achieved in the recently completed SG system linking the U.S. and France.
