What makes this feat revolutionary is not just the speed, but how it was achieved.
Using a standard 0.125 mm cladding diameter optical fiber, identical in size to the widely-used single-core fibers buried beneath our cities and oceans, the research team engineered a 19-core fiber that can carry 19 separate data streams—within the space of a single traditional fiber.
This innovative design bypasses the need for massive infrastructure overhauls, making ultra-high-speed data transmission a realistic upgrade for existing global networks.
For context, the US average internet speed stands at a modest fraction of this record—underscoring the transformative potential this breakthrough holds for global economies, communication systems, and data-driven industries.
With this achievement, we are inching closer to petabit-level networks becoming a practical reality, bringing us one step nearer to the kind of high-capacity internet needed for AI, immersive experiences, smart cities, and global collaboration at unprecedented scales.
The future of connectivity isn’t coming—it’s already being tested.
