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.
