Cape Town, South Africa - Nokia and Telkom South Africa's wholesale division Openserve have successfully conducted a trial of G.fast technology in an office complex in Pinelands, South Africa, reaching fiber-like speeds over existing copper infrastructure as deployed in buildings. This trial is a dry-run for Openserve's commercial deployment of G.fast later this year, meaning it will soon join the top 10 companies worldwide deploying the technology, part of its drive to rapidly expand its footprint across South Africa.
The results of the trial demonstrated an aggregate bandwidth (upstream and downstream) of 900Mb/s on short copper loops, and speeds of 500Mb/s downstream and 250Mb/s upstream on an existing copper line at a distance of 150m.
Nokia's G.fast technology uses the last few hundred meters of existing copper located in a building to deliver ultra-broadband access to customers, and it will allow Openserve to meet demands for fiber-like broadband speeds without significantly increasing operational cost. The built-in vectoring technology reduces cross-talk interference between copper lines, hence improving data speeds.
G.fast technology is increasingly being used in areas that are cumbersome to reach with fiber, allowing operators to deploy fiber-to-the building instead of each individual apartment unit - the most expensive and time-consuming part of a fiber-to-the-home deployment. As G.fast uses existing copper lines, it reduces disruption and lowers the barriers with home owners in multiple-dwelling complexes and home owner associations for granting permissions to upgrade infrastructure on their properties.
Openserve CEO Alphonzo Samuels said: "We completed testing Nokia's G.fast technology in our labs, and are extremely pleased with the results. G.fast provides us with a great alternative in scenarios where the length of the copper tail is 150m or less. Moreover, the business case is convincing. With G.fast, we have found a way to maximize the usage of some of our existing network infrastructure, while avoiding any disruption or possible harm to the aesthetics of the real estate. Nokia is our long-term innovation partner, and we take pride in continuing down that path, bringing more high-speed broadband services to citizens and business customers in South Africa."
Daniel Jaeger, head of Central, East and West Africa at Nokia, said: "This is one of the first G.fast trials worldwide, and we are proud to be a part of it. Service providers are grappling with different technologies to meet the ever-growing demand for high-speed internet, and this innovative solution allows them to use existing infrastructure to cater to market demand. G.fast offers the unique combination of fiber-like speeds with very limited additional investment needed, low-hassle deployments, and faster return-on-investment.'
Nokia is the industry leader in G.fast technology with more than 40 individual customer trials completed and 10 customers commercially deploying around the world, including Openreach , Chunghwa Telecom , A1 Telekom Austria , Energia Communicationsand Frontier.
