Vodafone says its new 400Gbps per wavelength optical system is a world first. The company worked with CIena to build the system to carry live traffic across Auckland.

It is part of a transport network boom taking place nationwide as telcos expand capacity to deal with increased demand on the back of streaming video and cloud computing which in turn is growing thanks to the nationwide fibre roll-out.

Last year Spark installed a 200-gigabit fibre link into its optical transport network. That fibre linked the Spark Global Gateway in Takapuna in the north of Auckland to a core router in Papakura in South Auckland and was connected to the Southern Cross cable. In July, it added a similar link between Invercargill and Christchurch in the South Island.  

Vodafone technology director Tony Baird says his company’s investment will get the transport network in shape for today and ready for the future. He says: “It is an important step on the roadmap to 5G and for a stack of other exciting innovations across New Zealand’s sprawling fibre and high speed wireless networks”.

The upgrade means Vodafone can send up to 17TB of throughput over a single fibre pair, that’s the same as 700,000 channels of 4K TV streaming at the same time or more than 100 million phone calls.
