KDDI rolls out Nokia gigabit solution for ‘au Hikari’ customers

5 Feb 2019

Japan’s KDDI is deploying Nokia’s gigabit solution in its commercial network to deliver ultra-broadband services to its customers. The vendor’s technology is interoperable with KDDI’s VDSL technology to provide a cost-effective migration path, enabling KDDI to offer 830Mbps combined uplink and downlink speeds to customers over its existing copper wire network at ‘an attractive price’, it claimed in a press release.

The solution – branded ‘au Hikari Type G’ – has been deployed in apartments and multi-dwelling unit (MDU) buildings and has been developed by Nokia Bell Labs, using vectoring technology to effectively reduce cross-talk interference that typically impacts data speeds over copper networks. TeleGeography notes that there are more than 30 million households using FTTH/FTTB services in Japan, of which approximately nine million live in MDUs. Further, there are between five and six million VDSL2 users that may seek to migrate to to secure higher broadband speeds, and Nokia’s platform should future-proof this by promising speeds of up to 2Gbps in the future.

Commenting on the deployment, Shigenari 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 solution enables us to connect existing 100Mbps users and new 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 is based on our long-term relationship, Nokia continues to be our long-term partner for delivering technology innovations.’
