Japan has set a new internet speed–distance record: 1.02 petabits per second over 1,808 km using a newly developed 19‑core optical fiber. That’s a million gigabits per second, far beyond your 1 Gbps home line. In this video, we break down how the tech works (multi‑core fiber, low‑loss wavelength bands, optical amplification relays), compare it to earlier milestones (0.319 Pbps in 2021, 1.7 Pbps in 2023), and explain why AI, 4K/8K streaming, and our insatiable data habits keep driving bandwidth higher. If you want to understand the future of fiber, and why “enough speed” never exists, watch this.
