This will be funded by a consortium consisting of Google and five telecoms companies; Bharti Airtel, Global Transit, KDDI Corporation, Pacnet and SingTel.

"The Unity cable system allows the members of the consortium to provide the increased capacity needed as more applications and services migrate online, giving users faster and more reliable connectivity," says Unity spokesperson, Jayne Stowell.

Google has previously expressed an interest in investing in network infrastructure. Last year Google announced that it has set aside a budget of $4.6 billion to purchase a section of the US wireless sprectrum.
