Japan’s National Institute of Information and Communications Technology (NICT) has made history by setting a new world record for internet transmission speeds. The incredible achievement of reaching 402 Terabits per second (Tbps) surpasses the previous record set by NICT itself last year, demonstrating a significant advancement in internet technology.
To put this groundbreaking speed into perspective, 402 Tbps equals a staggering 402,000,000 Megabits per second (Mbps). This speed is over 1.5 million times faster than the highest average fixed broadband internet speeds in the world, which are currently around 277-275 Mbps in Singapore and Hong Kong. NICT’s accomplishment represents a more than 20% increase over the previous record, showcasing a remarkable leap in internet transmission capabilities.
What sets this record apart is that it was achieved using commercially available optical cabling. The NICT team developed an optical transmission system that covers all transmission bands of standard optical fibres, known as the OESCLU system. This was made possible through innovative technologies, such as the world’s first O to U-band transmission system with Dense Wavelength Division Multiplexing (DWDM) capabilities. The use of custom-designed amplifier technology was also essential in achieving this remarkable feat.
Led by researchers from NICT’s Photonic Network Laboratory in Tokyo, the international team strategically amplified data signals to fully utilize the potential of fiber optic cables. By combining six doped-fiber amplifier variants with lumped and distributed Raman amplification, they were able to achieve a record-breaking 37.6 Terahertz (THz) of bandwidth across 50 kilometers of optical cabling. This achievement opens up new possibilities for high-speed data transmission and could potentially revolutionize internet connectivity.
NICT is optimistic about the future impact of this technology, especially as data services continue to expand rapidly. While current broadband networks and consumer hardware may not be ready to handle 402 Tbps, this record-breaking achievement paves the way for future advancements in internet speeds and data transmission. The success of NICT’s research highlights the potential for even greater innovations in optical communication, offering a glimpse into the future of digital connectivity.
As researchers push the boundaries of technology, we can anticipate further advancements in internet speeds and data transmission. The record set by NICT serves as a testament to the remarkable capabilities of our current technology and sets a new standard for optical communication. This achievement underscores the endless possibilities for innovation in the digital age, promising a future where connectivity knows no bounds.
