Spark, Vodafone and Telstra announced on Thursday that the Tasman Global Access (TGA) cable is officially in service and ready to carry vast quantities of Internet traffic between New Zealand and the world.
The three telecommunications companies have invested approximately $100 million to build the TGA cable – which stretches 2288km from Ngarunui Beach in Raglan, to Narrabeen Beach in Sydney Australia.
The cable has been constructed to deliver more international bandwidth and capacity for New Zealand, and to strengthen diversity and resiliency within the country’s telecommunications infrastructure.
The cable also serves as an important digital link to fast-growing Asian economic markets by enabling better connectivity to the five major international cable systems currently serving Australia.
The TGA is comprised of two fibre pairs, has a total design capacity of 20 terabits per second and has 20 repeaters which are used to amplify the optical signals along the length of the cable.
The consortium of Spark, Vodafone and Telstra have contracted Alcatel-Lucent Submarine Networks (ASN), now part of Nokia, to lay the TGA cable between Ngarunui Beach at Raglan and Narrabeen Beach in Australia
The TGA landing at Raglan on the West Coast of New Zealand provides important cable route diversity to the existing Southern Cross cable connecting New Zealand to Australia and the USA.
