Subsea cables: from Australia to Southeast Asia

Subsea cables, the arteries of our communication

It is called Indigo and it is a subsea cable that will span 9,000km, connecting Singapore and Perth, and onwards to Sydney. With landing stations in Singapore, Australia and Indonesia, Indigo – to be constructed by Alcatel Submarine Networks – will also allow connections between Singapore and Jakarta.

Google and other members in the consortium – including Australian research network AARNet, telcos Indosat Ooredoo, Singtel and Telstra, and SubPartners, – will be able to share ownership of spectrum on the cable, giving them the ability to independently take advantage of technology advancements and future upgrades as required.

Each of two fibre pairs on Indigo is designed to provide a minimum capacity of 18 terabits per second, which can be increased in future.

This will make it possible to transmit 7.2 million high-definition movies simultaneously from Singapore to Sydney.
According to Google, Indigo’s capacity will also enable people in the two cities to join eight million simultaneous high-definition Google Hangout video conference calls.

The Asia-Pacific region is currently served by a number of subsea cable systems, though fibre cuts to major cables such as the ageing SEA-ME-WE 3 had affected internet services in recent years.
The fact that Google is part of the Indigo consortium is also indicative of the cloud giant’s efforts to deliver higher service levels, Teo said.

“Rather than rely on third-party telcos to provide the links between its datacentres, Google will be able to do so on its own and get guaranteed bandwidth at a more predictable cost.”
