SX Tasman Express to improve connectivity between A/NZ

A coalition of partners have signed-up to use the SX Tasman Express (SX-TX) subsea cable, which will laid between Sydney and Auckland. 

Southern Cross, Alcatel Submarine Networks and OMS Group will look to deliver 400 terabits of additional capacity across 16 fibre pairs for Southern Cross customers under the partnership.

This project aims to strengthen the digital infrastructure and connectivity between Australia and New Zealand, improving the regional network backbone.

The Tasman Express subsea cable system will include Open Cable System architecture that will be compatible with future generations of submarine line terminals and optimised latency to support next generation digital applications.

The system design also includes ASN branching unit technology to facilitate an alternate Australian landing (subject to demand and final design confirmation).

OMS Group, in partnership with ASN, will lead the marine installation using its latest fleet of vessels.

By deploying the SX-TX system, it not only reinforces vital links between Australia and New Zealand but also strengthens the backbone of regional connectivity, OMS Group CEO Ronnie Lim said.

Southern Cross Cables president and CEO Laurie Miller said Tasman Express will enhance the digital infrastructure between Australia and New Zealand.

“With ASN and OMS’s support, this system delivers ultra-high capacity, low-latency fibre connectivity, meeting the evolving demands of AI-driven cloud regions in Sydney and Auckland,” he said.

The project is scheduled for completion in 2028.
