Indigo Project

Sydney-Perth-Singapore subsea cable investment

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.

Indigo Specifications

Indigo is a two fibre pair 'Open Cable' design that utilises spectrum sharing technology and will span approximately 9000 km, connecting Singpore to Perth and Perth to Sydney. Essentially they are two discrete systems as follows:

Indigo West

Indigo West will deliver cost effective, reliable, low-latency and diverse connectivity between Singapore & Perth. In addition there are two fibre pairs connecting Singapore to Jakarta via a branching unit.

Indigo Central

Indigo Central will deliver diverse, reliable and secure connectivity between Perth and Sydney, Australia. The new subsea route will compliment the existing terrestrial networks across Australia.

Project Delivery

The Indigo project has now been delivered:
