​Japanese researchers have set a new world record for internet speed, achieving a staggering 402 terabits per second (Tbps) using standard, commercially available optical fiber. This speed is approximately 1.6 million times faster than the average broadband speed in the U.S. ​

How Was This Achieved?

The breakthrough was accomplished by an international team led by Japan’s National Institute of Information and Communications Technology (NICT), in collaboration with Aston University and Nokia Bell Labs. They utilized a combination of six types of doped-fiber amplifiers and both lumped and distributed Raman amplification to cover all major low-loss transmission bands (O, E, S, C, L, and U) within standard silica optical fibers. This setup enabled an unprecedented optical bandwidth of 37.6 THz, facilitating the 402 Tbps data rate over a 50 km fiber span.

What Does This Mean?

While such speeds are not yet feasible for consumer use due to infrastructure and hardware limitations, this advancement demonstrates the potential of existing fiber-optic technology to support future high-capacity data transmission needs. It paves the way for innovations in fields requiring massive data throughput, such as cloud computing, real-time analytics, and next-generation internet services.​
