Question: When was the Trans-Pacific Express undersea cable, for which Nedonna Beach, Oregon is a terminus, commissioned?

Context paragraphs:
Pacific Fibre: Pacific Fibre is a New Zealand-based company that proposed to build a trans-Pacific undersea cable that was to have competed with the Southern Cross Cable operated by Telecom New Zealand.  The cable would have totalled 12,750 km (7,920 miles) in length, and the initial investment was projected to be US$350 million.  Customers included Vodafone New Zealand, Australian ISP iiNet, and the Kiwi Advanced Research and Education Network in New Zealand.

Southern Cross Cable: The Southern Cross Cable, operated by Bermuda company Southern Cross Cables Limited, is a trans-Pacific network of telecommunications cables commissioned in 2000.

Nedonna Beach, Oregon: Nedonna Beach is an unincorporated community in Tillamook County, in the U.S. state of Oregon.  It serves as the U.S. terminus of the Trans-Pacific Express undersea cable and Southern Cross Cable.  Nedonna Beach is west of U.S. Route 101 between Rockaway Beach and Nehalem Bay.

Paterson (Cape York) Telegraph Station: The Paterson Telegraph Station (later known as The Cape York Telegraph Station) was a telegraph station in Queensland, Australia.  It was the original location for the end of the Cape York Telegraph Line.  It was the landing point for the undersea cable Telegraph Cable between Cape York Peninsula and Thursday Island.

Alaska Communications System: The Alaska Communications System (ACS), also known as the Washington-Alaska Military Cable and Telegraph System (WAMCATS), was a system of cables and telegraph lines authorized by the U.S. Congress in 1900 and constructed by the U.S. Army Signal Corps.  The communications lines were to serve both military and civilian needs in the territory of Alaska.  By 1904, ACS comprised some 2100 mi of undersea cable, 1,400 plus miles of land lines, and a wireless segment across at least 107 mi .  On May 15, 1936 WAMCATS was renamed the U.S. Army Alaska Communications System.  The Alaska Communications System remained under the control of the Army Signal Corps until 1962 when it was taken over by the U.S. Air Force.  The ACS handled the radioteletype, radio telephone, 500 kHz ship-to-shore frequencies, collected communications intelligence, and other services for more than half a century in Alaska.

TPE (cable system): TPE or Trans-Pacific Express is a submarine telecommunications cable linking China, South Korea, Taiwan, Japan, and the United States.  The line is a $500 million USD joint venture between 6 telecommunication companies China Telecom, China Netcom, China Unicom, Chunghwa Telecom, Korea Telecom, and Verizon Communications (AT&T and NTT joined in March 2008).  Ownership of the cable is evenly split between the 6 participants.  Construction of this 11,000 miles (approx. 17,700 km) line was completed in September 2008, and the Japan branch was completed in January 2010.

Isle of Man to England Interconnector: The Isle of Man to England Interconnector is a submarine power cable connecting the transmission system of the Manx Electricity Authority to that of Great Britain.  With an undersea section of approximately 104 km , it is the longest AC undersea cable in the world.  It was laid in 1999 between Bispham, Blackpool, England, and Douglas Head on the Isle of Man, commencing commercial operations in November 2000.  It is capable of continuous operation of 40 MW at 90 kV.

Svalbard Undersea Cable System: The Svalbard Undersea Cable System is a twin submarine communications cable which connects Svalbard to the mainland of Norway.  The two optical fiber cable consist of two segments, from Harstad to Breivika in Andøy, and from Breivika to Hotellneset near Longyearbyen in Svalbard.  The segments from Harstad to Breivika are 74 and long, respectively, and the segments from Breivika to Hotellneset 1375 and .  Each consists of eight fiber pairs and there are installed twenty optical communications repeaters on each segment.  Each segment has a speed of 10 gigabits per second (Gb/s), with a future potential capacity of 2,500 Gbit/s.  The system is now the sole telecommunications link to the archipelago.

Wildman Whitehouse: Edward Orange Wildman Whitehouse (1 October 1816 – 26 January 1890) was an English surgeon by profession and an electrical experimenter by avocation.  He was recruited by entrepreneur Cyrus West Field as Chief Electrician to work on the pioneering endeavour to lay the first transatlantic telegraph cable for the Atlantic Telegraph Company between western Ireland to eastern Newfoundland.  This pioneering project of the Victoria era began in 1854 and was completed in 1858, however the cable functioned for only three weeks.  While Whitehouse sent the first telegraph communications in 16 August 1858 to the United States of America, he was ultimately held responsible for the undersea cable failure after he applied higher voltages in an effort to boost declining signals.

UK-Belgium 5: UK-Belgium 5 was a submarine communications cable linking the UK and Belgium.  It is notable for having been the very first international undersea cable system to use optical fibres rather than coaxial cable.
