Nokia has resumed its participation in the O-RAN Alliance

Nokia announced that Vocus, an Australian fiber and network solutions provider, has deployed Nokia’s solution to provide 200G optical links spanning more than 4,100 km between Brisbane and Darwin.

Nokia’s 1830 Photonic Service Switch (PSS) is used to upgrade Vocus optical network between Adelaide, Brisbane and Darwin to provide 200G with the ability to easily provide 300G and 400G in the near future. With this initiative, the rise of Vocus covers more than 7,100 km of fiber.

The deployment between Adelaide in Darwin and Brisbane in Darwin replaces the existing optical transport network to provide 100G and 10G services to Vocus Enterprise, Government and Wholesale customers.

The deployment of 2 non-regenerated 200G wavelength optical transport networks covers 70 sites, over a distance of 3000 and 4100 km respectively, and will help Vocus to optimize CapEx and reduce OpEx. The improved and higher capacity optical network enables Vocus to deliver the latest generation of quality optical services, connecting Darwin to Hypercloud data centers, regional locations and international submarine cables.

Nokia said its solution is based on a flexible spectrum hybrid architecture with a Colorless, Directionless, Contention-Free Flex-Grid (CDC-F) architecture at the Adelaide, Brisbane and Darwin terminal sites, and a larger solution. single Colorless-Flexgrid (CF) at regional level depot sites offering a total guaranteed 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. Nokia went on to say that it is a cost-optimized solution designed to combine 200G end-to-end traffic with more economical nodes in regional locations, allowing express traffic and regional traffic in selected locations. to be served by the same system.

Michael Ackland, Managing Director of Federal Government and Strategic Projects, Vocus, said: “Over the past decade, we have leveraged proven Nokia solutions to deliver a world-class experience to our customers. The successful modernization of our optical network on key routes reiterates our confidence in Nokia’s solutions and expertise. Nokia’s state-of-the-art optical solution helps us differentiate our services based on quality of experience.

Rob McCabe, Nokia Business Manager for Australia and New Zealand, said: “Nokia and Vocus have been partners for many years, and we are delighted to have helped them build a 200G optical network of this capacity. over such a long distance. This upgrade improves both the current and future capacity of the Adelaide, Brisbane and Darwin links to ensure that Vocus can meet the growing demands of data consumption while providing lightning-fast and reliable experiences for their customers. . “

One of the main benefits, for which I congratulate Vocus, is to continue to diversify their networks in Australia. Australian submarine networks in Australia have been historically exposed, two main landing points in Sydney and one in WA, meant international capability could be at risk if a severe storm did occur and a few ships dragged their anchors. The recent rupture of a submarine cable off the coast of Perth, reported above, highlights the need for redundant landing points.

Now with the Sunshine Coast landing point and Darwin landing point, we have a certain level of diversity and potential resilience. To be effective, terrestrial networks like this also need to be able to carry large amounts of traffic from these new landing points to all major population centers.

I asked Vocus about this resilience and Ackland provided the following comments: “In recent months, Vocus has announced or completed a series of major upgrades to our terrestrial and international fiber infrastructure, which will dramatically improve diversity and network redundancy in Australia.

“We are already modernizing our direct intercapital Sydney-Melbourne-Adelaide routes to offer four times the capacity. We are already upgrading our Sydney-Brisbane routes connecting regional centers to provide 20 times the capacity. our Adelaide-Darwin-Brisbane route to deliver a massive 25 times increase in capacity.

“We also announced Project Horizon, a new and existing 2,000 kilometer fiber network between Port Hedland and Perth. It will complement the western ring of Vocus’ national network and provide another layer of redundancy with Vocus having a network ‘digit 8’ rings across the eastern and western states of Australia. This will allow Vocus to provide geographically diverse backhaul from Darwin via Port Hedland.

“In addition, we have now announced the Darwin Jakarta Singapore Cable (DJSC), a 1,000 km cable connecting the Australian Singapore Cable (ASC) to the North West Cable System (NWCS) at Port Hedland. The system will interconnect with the Horizon project from Vocus. fiber optic from Perth to Port Hedland, with the completed network providing unmatched redundancy and reliability for Vocus customers in the Pilbara area and in the north and west of Australia.

“Combined, these major investments will provide a series of redundant network loops both nationally and internationally, establishing both Port Hedland and Darwin as new international entry points into Australia and connecting to substantial fiber capacity of these new points to our national network connecting all the capitals of the continent ”, concluded Ackland.
