Southern Cross Cables Limited (Southern Cross) has announced its Southern Cross NEXT cable (SX NEXT) has landed in Coogee Beach in New South Wales, Australia, as part of the final stage of the submarine cable rollout between Los Angeles and Sydney. And teh SX NEXT cable system is expected to be ready for service in Q2, 2022.

SX NEXT submarine cable network span approximately 15,857 kilometres to connects Australia, New Zealand, Fiji, Samoa, Tokelau, Kiribati, and the United States. It complements the existing Southern Cross Cable Network to form a robust Southern Cross ecosystem, strengthening the resilience of connectivity on U.S.-South Pacific routes.

SX NEXT cable is being deployed by Alcatel Submarine Networks (ASN), at a total cost of about US$350million.



The trunk of the SX NEXT cable spans about 13,500 kilometers connecting Sydney, Australia directly to Hermosa Beach, California, with four fiber pairs, providing total capacity of 72Tbps, equivalent of streaming more than 4.5 million Ultra HD 4k videos simultaneously.

The SX NEXT cable will deliver significant benefits once it is fully operational, and will essentially double the amount of direct international cable capacity connectivity from the East Coast of Australia to the West Coast of the United States.

“Australia and New Zealand will benefit from this new direct and low latency link with the technology innovation hub of the world in California. The new system will also complement our existing lowest latency links between Sydney and Auckland, and Auckland to Los Angeles enhancing our eco-system connectivity with our closest neighbours across the Tasman and the Pacific,” he said. “For Fiji, Tokelau and Kiribati in particular, the SX NEXT cable will provide the highest capacity connectivity they’ve experienced to date.

The project began in 2017 with an undersea survey which maps the seafloor to determine the ideal and safest route upon which to deploy the cable. Since then, the company has celebrated the initial connection with Hermosa Beach, California, Tokelau and Kiribati, and at Takapuna in New Zealand, prior to the landing in Coogee Beach, Australia. The project will move on to finalise the branch landings in Fiji and final splice in early January, and it is expected the cable will then be ready for service in Q2, 2022.
