Tonga Cable Limited was formed in November 2009, with approval of Government of Tonga, to build and manage a submarine fibre optic cable to connect Tonga to an international network. Preliminary work had started long before registration of the company. Feasibility study was conducted and several business cases were developed to identify the best possible option for Tonga.

After careful analysis of all the options, connection to Southern Cross in Fiji was selected as the best option. This project is financed partially by World Bank, partially by Asian Development Bank and the balance is provided by Tonga Communications Corporation (TCC).

Connection between Tonga and Fiji is part of the regional connectivity project which is aimed at connecting all Pacific Islands through submarine fibre optic cable.
