Palo Alto, CA--July 23, 1996-- Hewlett-Packard Co. (Palo Alto, CA) announced that its SDH-transmission test equipment is being used to help build an undersea lightwave-communications system. The fiber-optic link around the globe (also known as FLAG) is initially expected to span 16,950 miles between Great Britain and Japan. The $1.5 billion project consists of installing eight sections of fiber-optic cable running through the Mediterranean and Red seas, and through the Atlantic, Indian, and Pacific oceans. HP sold more than 50 of its synchronous digital hierarchy test sets to help AT&T Submarine Systems install and maintain the undersea cable -- sometimes referred to as "a glass necklace" because of the way the fiber-optic cable is strung around the globe. The instruments provided include the HP 37717B SDH and jitter tester, and the HP 37714A SDH test set.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
