SEA-ME-WE 3

SEA-ME-WE 3 or South-East Asia - Middle East - Western Europe 3 is an optical submarine telecommunications cable linking those regions and is the longest in the world, completed in late 2000. It is operated by India's Tata Communications and 92 other investors from the telecom industry. It was commissioned in March 2000.

It is 39,000 kilometres (24,000 mi) in length and uses Wavelength Division Multiplexing (WDM) technology with Synchronous Digital Hierarchy (SDH) transmission to increase capacity and enhance the quality of the signal, especially over long distances (this cable stretches from North Germany to Australia and Japan).

According to the cable system network administrator's website, the system capacity has been upgraded several times. The cable system itself has two fibre pairs, each carrying (as of May 2007) 48 wavelengths of 10 Gbit/s。
