KDDI deploys Nokia gigabit G.fast solution to bring new services to its high-speed internet 'au Hikari' customers in Japan

• KDDI deploys Nokia gigabit G.fast solution in live commercial network to provide  customers with 'au Hikari Type G' broadband services
• Nokia G.fast technology is industry's only solution that is interoperable with the Japan's VDSL technology

Nokia solution provides KDDI with economical migration path from VDSL to G.fast, enabling KDDI to offer 830Mbps combined uplink and downlink speeds to customers at an attractive price

Tokyo - 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 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's 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'.

Teresa Mastrangelo, principal analyst at Broadband Trends said: "G.fast continues to be a preferred choice for operators seeking to deliver gigabit broadband services to MDUs as it eliminates many of the issues found with FTTH deployments such as building types and access.  However, in Japan, deploying G.fast can be just as challenging as fiber due to the unique VDSL ecosystem and standards in place.  As one of the few vendors capable of supporting both the global and local Japanese VDSL standard, Nokia has been able to help KDDI capitalize on the benefits of G.fast and seamlessly scale and migrate their network with minimal disruption.  This win is another great example for how G.fast technology is being used to quickly address customers need for greater broadband speeds."
