The Future is Now: How Data Transmission Breakthroughs Will Reshape Our Digital World
The internet as we know it is on the cusp of a massive upgrade. Recent breakthroughs in data transmission – achieving speeds of 430 terabits per second (Tbps) over standard optical fibre and 2Tbps via satellite – aren’t just about faster downloads. They represent a fundamental shift in our ability to handle the ever-increasing demands of a data-hungry world, driven by artificial intelligence, immersive experiences, and the relentless growth of connected devices.
The Speed Revolution: Beyond Faster Downloads
Let’s put those numbers into perspective. 430 Tbps equates to roughly 54,000 gigabytes of data every second. That’s enough to download hundreds of HD movies in the blink of an eye. But the real impact lies in what this capacity unlocks. Currently, global networks are struggling to keep pace with the explosion of data generated by AI applications like generative AI (genAI). These advancements aren’t just about speed; they’re about enabling the next generation of digital innovation.
The key to this leap forward, pioneered by researchers at Japan’s NICT and the UK’s Aston University, isn’t simply throwing more power at the problem. It’s about smarter use of existing infrastructure. Instead of relying on traditional single-mode techniques, they’ve harnessed the potential of three-mode transmission using shorter O-band wavelengths within standard ITU-T G.654 optical fibre – the backbone of the global internet. This approach is not only faster but also more efficient, utilizing less of the cable’s total bandwidth.
AI, Data Centres, and the Insatiable Demand for Bandwidth
The driving force behind this push for greater bandwidth is undeniably AI. The training and operation of large language models (LLMs) require massive data transfers between data centres. As AI becomes more integrated into our lives, this demand will only intensify. Industry forecasts from Dell’Oro Group predict a 15% year-on-year increase in fibre optic demand, fuelled by the “positive momentum” created by the AI industry’s rapid growth. We’re already seeing a shift towards 400G backbones, with 800G and 1.6T networks rapidly gaining traction.
This isn’t limited to terrestrial networks. Subsea cables, the arteries of global communication, are experiencing a 30% annual increase in traffic. NBN Co in Australia, for example, is planning to replace its Sky Muster satellite service with Amazon’s Leo network, highlighting the growing importance of satellite connectivity in bridging the digital divide and supporting data-intensive applications.
Looking to the Skies: The Rise of Free-Space Optical Communication
While fibre optics continue to evolve, researchers are also exploring alternative solutions. Free-space optical (FSO) communication, which uses lasers to transmit data through the air, is gaining momentum. NICT recently demonstrated FSO data transmission at 2Tbps over a 7.4-kilometre distance, showcasing its potential for high-speed, stable connections, even in challenging environmental conditions. This technology is particularly promising for connecting ground networks with satellite services like SpaceX’s Starlink and Amazon’s Kuiper.
FSO offers several advantages, including higher bandwidth and greater security compared to traditional radio frequency (RF) communication. However, it’s also susceptible to atmospheric interference, such as fog and rain. Ongoing research is focused on mitigating these challenges to unlock the full potential of FSO.

The IOWN Vision: A Sustainable Future for Networks
The Connectivity industry group IOWN Global Forum is pushing the boundaries of optical fibre development with an ambitious vision: to reduce network power consumption by 100 times, reduce end-to-end latency by 200 times, and boost transmission capacity by 125 times. While these goals are currently beyond our technological reach, they represent a long-term roadmap for a more sustainable and efficient digital infrastructure.
This focus on sustainability is crucial. As data demand continues to grow, so too will the energy consumption of our networks. Developing more energy-efficient technologies is essential for mitigating the environmental impact of the digital revolution.
