Google is a member of a six company consortium that will build a new $US300m subsea fibre optic cable linking the United States and Japan.
Other members are: Indian telco, Bharti Airtel; Global Transit; Japanese telco, KDDI Corporation; Pacnet; and SingTel. Pacnet is the entity formed by the merger of Asia Netcom, which already operates an extensive Asian submarine network, and regional ISP Pacific Internet. Global Transit operates what is claimed to be the fastest growing IP Transit network in South Asia and is an affiliate of The AIMS Asia Group, a pan-Asian operator of network neutral data centres.

The members says the name Unity was chosen "to signify 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 fibre pairs." Unity will have eight fibre pairs but only five will be lit initially. Pacnet is the single largest investor in Unity and will control two of the five pairs. Other members have not revealed their relative shareholdings. Each of the fibre pairs is capable of carrying up to 960Gbps giving a maximum capacity of 7.68Tbps. The system is expected to be ready for services in the first quarter of 2010.

Pacnet's two pairs will be what it had previously planned as its own US-Japan cable, EAC Pacific. Announcing its participation in Unity is said "EAC Pacific will enhance connectivity and reliability of Pacnet’s existing pan-Asia EAC-C2C subsea cable network by providing up to 1.92Tbps of bandwidth across the Pacific."

Unity will run 10,000kms between Chikura, off the coast near Tokyo, and Los Angeles and other West Coast network points of presence. At Chikura, it will connect to other Asian regional cable systems including Pacnet’s EAC-C2C network.

NEC Corporation and Tyco Telecommunications (a subsidiary of India's Tata group ) have been jointly awarded the contract to construct and install the system. Construction will begin immediately.

According to the 2007 TeleGeography Global Bandwidth Research, Trans-Pacific bandwidth demand has grown at a compounded annual growth rate (CAGR) of 63.7 percent between 2002 and 2007. It is expected to continue to grow strongly from 2008 to 2013, with total demand for capacity doubling roughly every two years.
