Vocus enlists Nokia to drive 200G optical network over 4,000 km in Australia

Enterprise, government and wholesale customers set to benefit from improved broadband speeds and experience from 200G terrestrial optical network connecting Brisbane and Darwin

Leading communications technology provider Nokia has set up the 200G optical links for Australian fibre and network solutions provider Vocus in an infrastructure running for more than 4,100 km between Brisbane and Darwin.

The roll-out is the latest step in a Vocus capacity upgrade covering more than 7,100 km of fibre. The deployment between Adelaide to Darwin and Brisbane to Darwin replaces the existing optical transport network to provide 100G and 10G services to Vocus enterprise, government and wholesale customers.

The deployment of 2 x 200G based wavelength unregenerated optical transport networks covers 70 sites, over a distance of 3,000 and 4,100 km respectively is designed to help Vocus to optimise Capex and reduce Opex. Vocus also believes that the upgraded, higher capacity optical network will also allow it to provide the latest generation of quality optical services, in connecting Darwin to Hypercloud Data Centres, regional locations and international submarine cables.

In the deployment, Vocus is making use of Nokia’s 1830 Photonic Service Switch (PSS), which is seeing use in upgrading the optical network between Adelaide, Brisbane and Darwin to deliver 200G with the capability to easily provide 300G and 400G in the near future.

Nokia’s solution is based on a spectrum hybrid architecture with colourless, directionless, contentionless Flex-grid (CDC-F) architecture at the terminal sites at Adelaide, Brisbane and Darwin, and a simpler colourless-flexgrid (C-F) solution at regional drop sites providing a total warranted capacity of 10.8Tb (54x200G) between Adelaide, Darwin and Brisbane-Darwin. The solution is powered by Nokia’s Photonic Service Engine (PSE) super coherent digital signal processors.

In all, the optical routing technology is described as being cost-optimised and designed to combine end-to-end 200G traffic with more economical nodes in regional sites, allowing express traffic and regional traffic in selected locations to be served by the same system.

“Over the last decade, we have leveraged Nokia’s field-proven solutions to provide a world-class experience to our customers,” said Michael Ackland, general manager of federal government and strategic projects at Vocus. “The successful modernisation of our optical network on key routes reiterates our confidence in Nokia’s solutions and expertise. Nokia’s industry-leading optical solution helps us differentiate our services based on the quality of experience.”

Rob McCabe, head of enterprise for Australia and New Zealand at Nokia, added: “Nokia and Vocus have partnered for many years, and we’re delighted to have helped them build a 200G optical network of this capability over such a significant distance.

“This upgrade improves both the current and future capacity of the Adelaide, Brisbane and Darwin links to ensure Vocus can address growing data consumption demands while also delivering ultra-high speed and reliable experiences for their customers.”
