SEA-ME-WE 3

• South East Asia-Middle East-Western Europe 3– Germany to Australia, Taiwan, Korea and Japan

• operational since August 30, 1999

• 38 000 Km, 2 pairs of fibers – direct optical amplification

– wavelength division multiplexing (WDM)

– 8 wavelengths (colors) per pair of fibers

– bypass units allow the insertion/extraction of one or two colors per fiber

– 30 000 telephone circuits per wavelength

– 483 840 digital 64 kb/s circuits

• 33 countries, 25 years of lifetime, 1.5 B$
