The Pacific Ocean can now be crossed in a new way. Southern Cross Cables has officially launched its long awaited NEXT cable system with 400GbE services on tap.
Southern Cross NEXT spans 15,840km between Australia/New Zeland and California. The endpoints are in Sydney, Auckland, and Los Angeles with branches to Fiji, Tokelau, and Kiribati along the way. It is lit by Ciena’s coherent optical technology, with Southern Cross and Ciena achieving what is billed as the world’s longest single-span submarine 400GbE service.
The NEXT cable has been under construction for two years, and will boost Southern Cross’s capacity between the two regions by about 100Tbps or 500%. It also offers the current lowest latency route between Sydney and Los Angeles, according to the company.
Southern Cross’s older cable system is expected to be retired in 2030, and the NEXT cable is the first of the new generation. Presumably that means we will hear soon about a sibling of some sort.
