Nokia and Energia Communications are to set to launch the first commercial G.Fast service in Japan later this year.
The two companies are pressing ahead with a deployment after trials in 2015.
In particular, they are targeting multi-dwelling units where it is difficult to deploy pure fibre.
The country’s Chugokua region will be first to get the tech from June.
Naoki Okura, Head of Global Enterprise and Public Sector in Japan for Nokia, said: “G.Fast is quickly proving to be a great way to do [accelerate ultra-broadband deployments] in areas that are too complex or expensive to fully deploy FTTH solutions.”
Yesterday, Nokia revealed falling sales in Japan were partly responsible for a 12 percent fall in revenues in Asia Pacific last year.
G.Fast is emerging as a key tool for operators that have large copper networks.
Deutsche Telekom is trialing an advanced form of G.Fast, developed by Bell Labs, that promises even faster speeds.
The Finland-based vendor has over 34 G.fast ongoing trials with operators around the world.
Rivals continue to lambast these incumbents for what they view as short-term fixes.
The European Commission is hoping to push through legislation that will incentivise operators to invest more in fibre later this year.
