Nokia Monday said South Korea’s telecom player SK Broadband has been able to offer world’s fastest broadband speed based on the telecom gear maker’s technology. Nokia’ NG-PON technology coupled with SK Broadband’s network offered 52.5 Gbps speed and the service has been offered to a set of apartment buildings in Seoul.
To achieve this Nokia’s universal next generation PON architecture combined different technologies on a single fiber, thus maximizing the use of SK Broadband’s fiber investment, it said in a statement.
With Nokia, they are now taking their fiber network to the next level. Reusing the existing fiber network and access platform, on which they already have deployed Gigabit Passive Optical Network technology (GPON) at 2.5 Gbps, they can now boost speeds up to 52.5Gbps.
To do so, SK Broadband is using multi-dwelling units (MDUs) from HFR and Nokia’s universal next generation PON solution, making it possible to aggregate different technologies on the existing fiber.
Nokia combined TWDM-PON with 40Gbps symmetrical with XGS-PON with 10Gbps symmetrical and GPON with 2.5Gbps to achive the total 52.5 Gbps speed,
In addition to boosting speeds, universal next generation PON also brings the benefit of cost-efficient upgrades and operational efficiencies thanks to the wavelength mobility.
In 2006, SK Broadband was the first to commercialize 2.5Gbps GPON technology. In 2014, they introduced the world’s first 10 Gbps Internet service jointly with the Ministry of Science, ICT and Future Planning, and the National Information Society Agency using 10Gbps E-PON technology.
South Korea is known as the world’s most connected country offering the world’s top upload and download speeds, and it has set clear strategic goals to have Gigabit broadband available to all citizens by 2020.
“As a new era looms that demands Gigabit Internet, Ultra High Definition video and Virtual and Augmented Reality services, SK Broadband will establish a network infrastructure that provides the best customer value. Following the world’s first commercialization of an ADSL service and the two-pair LAN cable 500M service, we will establish a top-class optical Internet platform to create the best Gigabit broadband service environment for our customers,” said Yoo Ji-chang, Head of SK Broadband’s Network Division.
With this latest generation of fiber access technologies, SK Broadband aims to take its commitment yet one step further to offer speeds of 10 Gbps to all its customers. This will boost the country’s highly competitive business environment as well as the innovations in broadband services delivered to the market.
“All eyes in the world are focused on South Korea as it moves ahead with rolling out ever-faster broadband networks. Nokia’s innovation edge and our portfolio of next generation fiber technologies help customers like SK Broadband realize the true Gigabit societies of the future,” said Federico Guillen, president of Nokia’s Fixed Networks Group.
