Japan's KDDI is deploying Nokia's G.fast solution to apartments and multi-dwelling units (MDU) buildings to deliver ultra-broadband services to customers.

Reducing the need to install new fiber, Nokia's technology will enable KDDI to use existing copper lines in MDU buildings to deliver 830Mbps combined uplink and downlink speeds to customers.

To support customers' ultra-broadband needs, Japanese operators are using fiber where possible along with new technologies like G.fast for a large number of MDU locations where copper is already installed. Developed by Nokia Bell Labs, G.fast uses vectoring technology to effectively reduce cross-talk interference that typically impacts data speeds over copper networks. 

Providing support for Japan's VDSL2 specifications, Nokia said its G.fast solution will minimize the impact to existing VDSL systems and enable operators to quickly upgrade their high-speed internet service to gigabit class through a simple CPE (customer premises equipment) replacement.  

KDDI has been deploying Nokia's G.fast solution and has started its rollout of 'au Hikari MDU Type G'.

Shigenari Saito, Administrative Officer, GM, Network Technology Development Division, KDDI
KDDI already provides 10Gbps service for our 'au Hikari' FTTH customers, but the speed we can provide has been limited to 100Mbps service for MDUs where fiber is difficult to deploy.  Nokia's G.fast solution enables us to connect existing 100Mbps users and new G.fast users under the same DPU (distribution point unit).  

Sandra Motley, President of Nokia's Fixed Networks Business Group
Operators looking to quickly roll out new ultra-broadband services are increasingly adopting multi-technology strategies that allow them to maximize the use of both fiber and copper technologies.
