This marks the completion by AARNet of the Sydney shore end work.

Alcatel Submarine Cable Networks (ASN)’s cable ship, the Ile de Brehat, will now continue laying the cable north towards Guam, with the completion of JGA South on-track to be completed and ready for service by March 2020.

This new eastern seaboard telecommunications cable will complement the recently completed INDIGO cable system forming an all-important ring between Australia and the fast-growing North and South East Asian markets.

Using today’s coherent optical technology, JGA South’s two-fibre pairs will support up to 36 terabits per second, the equivalent of simultaneously streaming millions of movies a second with lower latency and enhanced reliability.

JGA South will utilise ASN’s spectrum sharing technology where each consortium member can independently take advantage of technology advancements for future upgrades and capacity increases on demand.

This is especially relevant to the high bandwidth demands of research in Australia.
