Photonics: A New Era for Data Transmission
Photonics, the technology of using light for computing, is no longer a distant prospect. NTT’s APN technology, a cornerstone of their IOWN framework, is actively being tested with connection trials between data centres in the United States and the United Kingdom. This ambitious initiative aims to demonstrate the potential of APN-based distributed data centres in supporting international business operations. “Our trials are a testament to NTT’s dedication to expanding photonics-based technology capabilities,” stated Kinoshita.
The APN service, renowned for its large capacity and low latency, facilitates the optimal arrangement of computational resources and data. This innovation enables the flexible and secure utilisation of GPU clouds, a critical component in meeting the growing demands of AI and machine learning applications. A notable application discussed was LLM fine-tuning, where the technology ensures operational consistency across remote bases.
Cognitive Foundation and Energy Efficiency
Central to NTT’s strategy is the Cognitive Foundation, which aligns computation with the fluctuating supply and demand of green energy. By promoting local production and consumption, NTT enhances renewable energy efficiency. This initiative is crucial for addressing challenges such as extending GPU clusters in urban data centres, where space is often restricted. Kinoshita emphasised the importance of dynamically arranging workloads based on renewable energy conditions, highlighting NTT’s commitment to sustainable technology practices.
The introduction of on-demand connections marks a significant advancement in this domain. Unlike traditional leased lines, these connections can be established end-to-end as needed, facilitated by innovations in optical path design technology and wavelength conversion techniques. This development allows multiple wavelengths to coexist without collision, significantly improving network efficiency and flexibility.
Innovations in Chip Development
NTT is at the forefront of addressing inter-chip-wiring power consumption challenges. Traditional cooling techniques are nearing their limits, prompting a shift towards photonics solutions. Light-based inter-chip wiring offers an energy-efficient alternative, as its power consumption does not increase with distance. NTT’s advancements in silicon and membrane photonics are paving the way for more compact and efficient optical transceivers, which are essential for the next generation of data communication technologies.
Kinoshita elaborated on the potential of these innovations, stating, “By shrinking optical devices and boosting their efficiency, we are moving towards a future where our technology is not only more powerful but also more sustainable.”
