The Australia-Singapore Cable (ASC) is a 4,600-km submarine cable system linking Perth, Australia and Singapore, through the Sunda Strait in Indonesia, providing the first 100Gbit/s high-speed connection from Western Australia to South East Asia.

The Australia Singapore Cable (ASC) project was launched by Nextgen Networks and Vocus jointly, based on a 50/50 joint venture. In April 2017, Vocus Communications completed the acquisition of Nextgen Networks to own 100% of the ASC. 

The ASC cable system is designed to carry 40Tbps with four fibre pairs.

The ASC cable system has been ready for service since September 2018.

ASC, Indigo and Trident cable systems enable high bandwidth and redundant routes and connectivity between Singapore and Australia.
