the technical details are difficult to comprehend ; the result is , however , simple in concept . “ At the moment , everything in the current infrastructure is driven by electricity ,” Higashiyama says . “ Inside data centres , even those for fibre networks , a lot of energy is expended . That ’ s because we need to convert all the optical ‘ photonic ’ signals into an electric signal , compute something , and convert the signal again from electronic back to photonic . It is not efficient and it requires an enormous amount of energy . But in the all-photonics future , you no longer need to convert the signal . The technology allows the signal to flow between destinations seamlessly , and therefore dramatically cuts energy consumption .”
“ In the 5G era , NTT DATA needs to strengthen our crossindustry activity ”

By leveraging all-photonics technology , NTT DATA forecasts a 100x reduction in energy consumption . Collaborating with Fujitsu to develop a hyper-energy exchange network and IT infrastructure , NTT R & D is commercialising the technology for communication service providers ( CSPs ). Without this dramatic decrease in energy consumption , Higashiyama believes that current infrastructure will no longer be sustainable in as little as three years ’ time .
“ Green technology is key to our success . As network traffic will continue to exponentially grow roughly 20-30 % year-onyear , the network will require twice as much energy as it currently does within the next three to five years ,” he says . “ That growth will
