The Southern Cross Cable, operated by Bermuda company Southern Cross Cables Limited, is a trans-Pacific network of telecommunications cables commissioned in 2000. The network has 28,900 km of submarine and 1,600 km of terrestrial fiber optic cables, operated in a triple-ring configuration. Initially, each cable had a bandwidth capacity of 120 gigabit/s,〔(Southern Cross Cables Network )〕 but was doubled in an upgrade in April 2008,〔(Big Southern Cross Cable Upgrade for High Speed Broadband )〕 with a further upgrade to 860 gigabit/s at the end of 2008.〔(Southern Cross upgrades planned in 2008 )〕 Southern Cross upgraded the existing system to 1.2 Tbit/s in May 2010.〔(Broadband in for another price fall and capacity boost )〕 After successful trials of 40G technology the first 400G of a planned 800G upgrade has been completed in February 2012, with the remaining 400G completed in December 2012.〔(Southern Cross committed to Ultra Fast Broadband and National Broadband Network )〕 An additional 400G was deployed utilising 100G coherent wavelength technology in July 2013, taking total system capacity to 2.6Tbit/s, with an additional 500Gbit/s to be deployed per segment by Q2 2014, increasing total system capacity to 3.6Tbit/s. The latest augmentation will also deploy Ciena FlexiGrid technology, increase Southern Cross potential capacity to 12 Tbit/s. Southern Cross offers capacity services from STM-1 to 100Gbit/s OTU-4, including 1G, 10G and 40G Ethernet Private Line services. ==Landing points== #Alexandria, NSW, Australia #Brookvale, NSW, Australia #Suva, Fiji #Whenuapai, New Zealand #Takapuna, New Zealand #Kahe Point, Oahu, Hawaii, USA #Samuel M.
