Telstra Endeavour

The Telstra Endeavour is a submarine cable connecting Sydney and Hawaii. The cable went live in October 2008,[1] with a capacity of 1.28 terabits per second in the future (currently at 80 gigabits per second.) It was proposed[2][3] on 28 March 2007 by Telstra, the largest telecommunications carrier in Australia.

Telstra announced that the cable would connect Sydney and Hawaii with a 9,000 km link, the largest ever built and owned by an Australian company, providing a transmission capacity of 1.28 terabit/s to Hawaii. The cable will be linked to others from Hawaii to the US mainland.

The manufacture and laying of the cable was the responsibility of Alcatel-Lucent, which also supplied Telstra's two cables across Bass Strait and its Tasman Sea (TASMAN 2) cable. Alcatel-Lucent is basing this turn-key project[5] on the "Alcatel 1620 Light Manager"[1] Submarine Line Termination Equipment that uses Dense Wavelength-division Multiplexing (DWDM). No cost was revealed, however it is estimated around $300 million (AUD).
