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).[1][2] 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,[3] and the Japan branch was completed in January 2010.[4]

At the time of its construction, 5,547 gigabits per second of capacity was available across the Atlantic Ocean, but only 2,726 gigabits per second existed across the Pacific Ocean.[2] Most links to China had to go through a hub in Japan, and access topped out at 155 Mbit/s.[5] The TPE is more than 60 times the overall capacity of the existing cable directly linking the U.S. and China, and thus its construction was a major enhancement to the cable systems between the two nations.[6] It is the first next-generation undersea optical cable system directly linking the U.S. and China,[7] and was also the first major undersea system to land on the U.S. West Coast in more than seven years.[8] Initially, the Trans-Pacific Express cable was configured to handle traffic at 1.28 terabits per second (Tbit/s), but the system has a design capacity of up to 5.12 Tbit/s. Customers can also book individual connections running at 10 Gbit/s.[2]
