    New Internet Speed World Record: Fiber Optics Achieve Unprecedented 402 Tb/s

    In a groundbreaking achievement, researchers at Japan’s National Institute of Information and Communications Technology (NICT) have set a new world record for data transmission speeds, reaching an astonishing 402 terabits per second (Tb/s). This new speed is approximately 5 million times faster than the average broadband speed in the UK, showcasing the immense potential of fiber optics in revolutionizing internet speed.

    The Breakthrough in Fiber Optic Technology

    The team at NICT, led by the Photonic Network Laboratory, accomplished this feat by constructing a system capable of covering all transmission bands of standard optical fibers. They utilized a combination of various amplification technologies to unlock previously unused wavelength regions. The result is a method that could be integrated into future telecommunication networks, significantly enhancing the communication capacity of optical communication infrastructure as demand for data services continues to grow.

    To put this into perspective, according to Ofcom, the average home broadband speed in the UK in 2023 was 69.4 Mbps, with the fastest speeds advertised at 1.13 Gbps. Even these fastest speeds are roughly 400,000 times slower than the new record. At a data rate of 402 Tb/s, one could download approximately 12,500 films in a single second, which is more than three times the number of movies currently available on Netflix.


    Optimal Conditions and Future Research

    The record-breaking speed was achieved under optimal laboratory conditions, using commercially available optical fibers. However, the real-world application of this technology requires further research. NICT researchers are optimistic about extending the transmission range to trans-oceanic distances, which could potentially revolutionize global internet infrastructure.

    Advancements in Fiber Optic Amplification

    The NICT team’s success stems from their innovative approach to optical transmission. They combined various signal amplification methods, including doped fiber amplifiers and distributed Raman amplification, to cover the entire low-loss spectrum of standard fiber optic cables. Their system utilized an unprecedented 37 THz of bandwidth over 1,505 separate transmission channels across 31 miles of cable.

    This achievement not only shatters the previous record by more than 25% but also increases the usable transmission bandwidth by 35%. The theoretical maximum data rate of 402 Tb/s, with a decoded data rate of 378 Tb/s after error correction, demonstrates the potential of existing fiber optic technology to achieve ultra-high-speed data transmission.


    Implications for Future Telecommunication Networks

    The implications of this breakthrough are vast. By lighting up new wavelength territories across deployed fiber networks, service providers can enhance data rates and extend the lifetime of their existing infrastructure. Combining these new bands with next-generation fiber types could help future-proof networks, making them ready for the demands of “Beyond 5G” services.

    Previous NICT contributions are highlighted in red. The previous record was a 2023 European Conference on Optical Communications (ECOC) paper ‘301 Tb/s E, S, C+L-Band Transmission over 212 nm bandwidth with E-band Bismuth-Doped Fiber Amplifier and Gain Equalizer’. (Source: NCIT JP)

    However, unleashing these speeds for real-world use would likely require costly upgrades to amplifiers and transmission equipment on both ends of the fiber line. Despite these challenges, the research highlights the untapped potential of current fiber optic technology and its ability to support future data services.

    The record-breaking 402 Tb/s data transmission speed achieved by NICT is a testament to the power and potential of fiber optics. As demand for faster and more reliable internet continues to grow, advancements in fiber optic technology will play a crucial role in meeting these needs. This achievement not only sets a new benchmark in data transmission but also paves the way for future innovations in telecommunication networks. The future of internet speed looks incredibly promising, thanks to the ongoing research and development in fiber optic technology.
