Southern Cross is an independent company that provides capacity, mostly undersea, to network operators and their ISPs in Australia, New Zealand and the Asia-Pacific region. Shareholders include New Zealand's Spark provider, Australia's Singtel Optus, Verizon (NYSE: VZ) and Telstra.
Southern
Cross's key projects was his just-announced NEXT cable. It operates between
Sydney, Auckland and Los Angeles, with fiber optic connections to the islands
of Tokelau, Kiribati and Fiji. NEXT took two years to complete and is one of
three cable systems that will form the Southern Cross ecosystem in the
Asia-Pacific region.
Ciena networks are leading optical networking company, provided the underwater switching
technology that forms the basis of NEXT. The switch implemented was a WaveLogic
5 Extreme (WL5e) model with coherent optics, a laser designed to transmit large
amounts of data over long distances. WL5e connections operate at speeds of up
to 800 Gbps and are used in the networks of Comcast, Deutsche Telekom, Spark,
Sparkle, Telus, Verizon, Vodafone New Zealand, and Windstream, to name a few.
The
Cienas WL5e
was the provider's platform for operating his GeoMesh Extreme technology and
connected the rest of the cables in the Southern Cross ecosystem to his NEXT.
As the name suggests, GeoMesh creates a network between terrestrial and subsea
connections. This is more difficult than it sounds. The optical signal is a
type of packet used on land using technology that is routed over an undersea
link from an inland terrestrial Point of Presence (PoP), rather than from a hut
on the shore, and is deployed under the waves. Must support exchange.
GeoMesh uses
artificial intelligence (AI), monitoring and telemetry, software-defined
networking (SDN), integration testing, and other measures to track network
performance and prevent fiber damage from passing ships or tsunamis. Fix the
unavoidable errors that occur when etc. will be interrupted. and other marine
threats.
