Telco Trio Launches TGA Subsea Cable

Spark, Vodafone and Telstra have officially put in service the Tasman Global Access (TGA), ready to carry internet traffic between New Zealand and the world.

The three telecommunications companies have invested approximately $100 million to build the TGA cable – which stretches 2288 kilometers 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 a digital link to Asian economic markets by enabling connectivity to the five 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 cable was laid by the Alcatel Submarine Networks Ile De Re cable-laying ship.
