SK Broadband is leveraging Nokia's next generation PON technologies such as the XGS-PON and TWDM-PON to deliver the world’s fastest fibre access speeds of up to 52.5Gbps to a first set of apartment buildings in Seoul, South Korea. 

With this latest generation of fiber access technologies, SK Broadband aims to take its commitment yet one step further to offer speeds of 10Gbps to all its customers.

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. SK Broadband is combining 40Gbps symmetrical TWDM-PON, 10Gbps symmetrical XGS-PON and 2.5Gbps GPON.

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, said Nokia.

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.

Federico Guillen, president of Nokia's Fixed Networks Group
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.
