Record Data Transmission Achieved with Fiber Optic Breakthrough
Updated May 31, 2025
Scientists have achieved a major breakthrough in fiber optic technology, reaching data transmission speeds of 1.02 petabits per second. This feat, accomplished by Japan’s National Institute of Data and Communications Technology (NICT) and Sumitomo Electric Industries, could download all movies on Netflix 30 times over. The new technology transmits data across 1,808 kilometers using a single fiber, no thicker than a human hair.
The core of this advancement is a 19-core optical fiber, designed to integrate into current infrastructure. Each core functions as an self-reliant data channel, creating a “19-lane highway” within the space of traditional single-core fibers. This innovative design eliminates the need for expensive infrastructure upgrades.
The fiber operates efficiently across the C and L bands,which are commercial standards used globally. A refined core arrangement reduces signal loss by 40% compared to previous models. This enhanced efficiency allows for reliable data transmission over long distances.
the experiment used a recirculating loop system, where signals traveled thru an 86.1-kilometer fiber segment 21 times. This simulated a cross-continental journey, equivalent to linking Berlin to Naples or Sapporo to Fukuoka. A dual-band optical amplification system maintained signal integrity, boosting signals in the C and L bands. This allowed 180 distinct wavelengths to carry data simultaneously using 16QAM modulation.
At the receiving end, a 19-channel detector, combined with advanced MIMO processing, disentangled interference between cores. This process is similar to separating 19 overlapping conversations in a crowded room. The digital signal processor corrected distortions accumulated over the 1,808 km, extracting usable data at unprecedented rates.
this achievement builds on previous progress. In 2023, the same team reached 1.7 petabits per second, but only across 63.5 km. The new 19-core fiber’s uniform design overcomes issues faced by earlier multi-core designs, achieving a capacity-distance product of 1.86 exabits per second per kilometer. This is 14 times higher than previous records for standard fibers, marking a meaningful leap in data transmission technology and fiber optic capabilities.
The research was presented at OFC 2025 in San francisco, as global data traffic is projected to triple by 2030. this breakthrough offers a viable path to petabit-scale networks, positioning fiber optics as a critical component of future internet infrastructure. The new fiber optic technology promises to revolutionize data transmission.
Researchers aim to refine production techniques for mass deployment, perhaps enabling transoceanic cables that move entire data centers’ worth of information hourly.
