Unity Cable System or EAC-Pacific is a 9620-km linear Trans-Pacific submarine cable system with direct cable route linking the U.S. and Japan. Unity represents a new type of consortium, born out of potentially competing systems, to emerge as a system within a system, offering ownership and management of individual fiber pairs.
The Trans-Pacific Express (or TPE) submarine cable system is the second subsea cable system directly linking China and the USA (China-US CN), aims to offer high capacity between the USA and China as well as other Asian countries and regions, to support future Internet growth and applications such as video and e-commerce. Unlike the other trans-pacific subsea cable systems which make Japan as a hub for traffic between the USA and Asia countries, the TPE cable system enables an alternative and direct routes between China, Korea, Taiwan and the USA.
TGN-Pacific (Tyco Global Network, or Tata TGN-Pacific) was initially builded, designed and operated wholly by Tyco Telecommunications, completed in December 2002. TGN forms a self-healing ring connecting the U.S. to Japan. On May 3, 2005, Tata Communications(formerly VSNL) announced the acquisition of TGN for $130 million,or Rs 585 crore, in a cash deal.
The PC-1 Network
The Pacific Crossing PC-1 trans-Pacific network consists of four fiber-pairs organized in four segments connecting each of the landing stations near major metropolitan areas in the U.S. and Japan: Harbour Pointe, Washington (near Seattle); Grover Beach, California (between San Francisco and Los Angeles); Ajigaura, Japan (near Tokyo); and Shima, Japan (near Osaka and Nagoya).
The AAG cable system (Asia-America Gateway) is the first transpacific submarine cable system linking South East Asia directly with the USA, provides connectivity between Malaysia, Singapore, Thailand, Brunei Darussalam, Vietnam, Hong Kong SAR, Philippines, Guam, Hawaii and the US West Coast. The AAG cable system has significant advantages over the traditional trans-Pacific routes (via the North Pacific) as it avoids the areas most prone to seismic activity off the Taiwan region, which have previously resulted in damage to undersea cables and network disruptions. The AAG submarine cable system was ready for service on Nov. 10, 2009.
