The Indigo Project

Indigo Consortium

The Consortium members include AARnet, Google, Indosat, Singtel, SubPartners, and Telstra, with each operator contributing unique attributes. The combined capabilities of these operators along with surety of funding will ensure the system reaches RFS (Q1 2019) and meets its full potential.

The Indigo cable, unique in its design as an 'Open Cable', utilises spectrum sharing tachnology, meaning that consortium members are free to independently select their own cable station transmission technology which ultimately determines the number of carriers used on a fiber pair and their underlying supported payload data rate.

The Indigo cable systems will land in existing facilities operated by the consortium members in Singapore, Australia, and Indonesia. Each consortium member will have spectrum ownership providing the ability to independently take advantage of future technology advancements and future upgrades as required.
