Nokia, nbn Australia explore ultra-broadband future

Australia’s nbn [national broadband network] has successfully tested Nokia’s universal NG-PON fibre solution in Nokia’s Melbourne lab facility. The trial achieved aggregate broadband speeds of 102Gbps on a single fibre and demonstrated the dynamic provisioning of bandwidth to support surging data demand from residential and business customers.

Universal NG-PON converges TWDM-PON (also known as NG-PON2), XGS-PON and GPON technology on the same fibre, and provides a simple upgrade path from current fibre technology used in FTTP deployments.

Easily deployed as an overlay on existing fibre networks, TWDM-PON and XGS-PON can save the time and additional cost that typically comes with laying new fibre. TWDM-PON provides four or more wavelengths on a fibre, each capable of supporting asymmetrical or symmetrical bit rates of 2.5Gbps or 10Gbps for a total of 40Gbps. XGS-PON uses one wavelength to provide either 10Gbps symmetrical or asymmetrical bit rates.

nbn was able to trial the different PON technologies using Nokia’s universal next-generation PON solution. This included:

  • TWDM-PON with 40Gbps symmetrical
  • XGS-PON with 10Gbps symmetrical
  • GPON with 2.5Gbps

Collectively, the technologies delivered download and upload speeds of more than 102Gbps aggregate over a single shared access fibre.

With the ability to significantly expand the data capacity delivered, TWDM-PON could allow customers to download a two-hour, 4K-quality video in seconds. With the use of advanced software, the technology can also enable the dynamic provision of data capacity on the network, giving operators such as nbn new options to flexibly meet changing user needs.

nbn continues to innovate and invest in technologies that will offer its business and residential customers the speed and quality of service required in the future. The successful test of TWDM-PON and XGS-PON is the latest in a number of trials nbn has conducted with Nokia across fibre and copper, including XG-FAST.

“Our successful trial of NG-PON2 technology with Nokia is another example of our ongoing commitment to continually develop the capabilities and speed of the nbn network,” noted Dennis Steiger, Chief Technology Officer of nbn. “While we continue to deploy the nbn network at pace with over two million end-users now receiving nbn services and nearly five million able to order a service, we also have a very sharp focus on the future. The NG-PON2 trials we have conducted with Nokia have shown us the huge potential this very exciting technology has in terms of helping us deliver on our future bandwidth and capacity requirements.”

“nbn is a valued and long-term customer, and we are committed to bringing our latest innovations to them and the country of Australia,” confirmed Ray Owen, head of Oceania at Nokia. “The trial of our universal NG-PON solution reflects that commitment, and demonstrates how we can help evolve nbn’s network now and in the long term to meet the increasing data demand of subscribers across the country.”
