KDDI, a leading telecommunications operator in Japan, 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 fibre 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’s G.fast solution will minimise 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’.

Saito, Administrative Officer, General Manager, Network Technology Development Division, Technology Sector, at KDDI said:  “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 fibre 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).  This gives us the flexibility and economical path to meet the customer’s demands for higher speed.  Our decision to deploy Nokia G.fast is based on our long-term relationship,  Nokia continues to be our long-term partner for delivering technology innovations.”

Sandra Motley, president of Nokia’s Fixed Networks Business Group, said: “Operators looking to quickly roll out new ultra-broadband services are increasingly adopting multi-technology strategies that allow them to maximise the use of both fibre and copper technologies. This is particularly true in some cases like inside an apartment building, where more traditional Fibre-to-the-Home solutions can be very challenging to deploy. We are excited to be working with KDDI to deploy our G.fast solution to deliver fibre-like speeds that will enhance the way customers experience their broadband services.”
