Research Conducted by the National Institute of Information and Communications Technology of Japan Demonstrated, in 2025, Data Transmission at 125,000 GB per Second Over 1,800 Kilometers, Using 19-Core Optical Fiber Based on Light, Establishing Internet Speed Almost 4 Million Times Higher Than Conventional Internet
The internet reached a new technological milestone after Japanese researchers demonstrated, in 2025, data transmission 4 million times faster than conventional internet, using light to send information over long distances and redefining speed and digital communication limits.
The Evolution of the Internet and the Transition to a New Digital Era
The internet has become one of the main foundations of the so-called digital age since its creation in the 1960s, accompanying advancements in sectors such as education, health, and finance. Over the past decades, the expansion of the internet has driven structural transformations in data circulation.
In recent years, technological developments have indicated the transition to a new phase known as the smart era. This period is characterized by the rapid growth of technologies such as artificial intelligence and automation, which have significantly increased the global dependence on the internet.

With the constant increase in the volume of information processed daily, the traditional internet infrastructure has begun to face limitations related to speed and transmission capacity, requiring new technological solutions capable of sustaining the growing demand for data.
Growing Global Demand Pressures Conventional Internet
Digitalization has expanded the use of the internet into industrial and productive areas, driving the growth of the so-called industrial internet. As a direct consequence, there has been a significant increase in the number of data centers needed to support digital operations and smart systems.
This growth has raised global data demand to record levels, putting direct pressure on existing communication networks. In this scenario, researchers have begun to seek alternatives capable of overcoming the technical limits of conventional internet.
A team led by the National Institute of Information and Communications Technology of Japan has proven that conventional internet may become obsolete sooner than expected. The results indicate the possibility of advancing to a new stage based on faster and more efficient data communications.
Light-Based Internet Achieves 125,000 GB per Second
In 2025, the National Institute of Information and Communications Technology confirmed a new record for internet speed and transmission distance. The team was able to transmit 125,000 GB of data per second over 1,120 miles, equivalent to approximately 1,800 kilometers.
According to an explanation released by Live Science, this rate corresponds to almost 4 million times the average speed of the internet in the United States. The volume transmitted is equivalent to 1.02 petabits per second.
With this capacity, it would be possible to download the entire Internet Archive in about four minutes, demonstrating the potential achieved when new optical technologies are applied to internet infrastructure.
19-Core Optical Fiber Enabled Internet Advancement
The recorded performance was made possible by the development of an optical fiber composed of 19 cores, made from glass fibers designed with a specific coating to enhance the data transmission rate through light.
During the tests, the optical signal traveled through a physical cable of 86 kilometers. Amplifiers were used to strengthen the signal before transmission, allowing it to make a repeated return circuit 21 times.
This process resulted in a total transmission distance of approximately 1,800 kilometers, maintaining stability and performance throughout the entire route of the light-based internet.
Results Presented at International Communications Conference
The research results were presented during the Annual Conference on Fiber Optic Communications held in San Francisco. The demonstration drew attention for establishing new technical parameters related to internet speed and range.
Although the advancement does not represent the immediate end of conventional internet, the study points to the development of hybrid networks capable of integrating traditional and quantum communications within the existing infrastructure.
This integration is considered essential to ensure security and efficiency in critical infrastructures and essential operations that directly depend on the internet in the current digital age.
The experiment conducted in Japan demonstrates that using light as the primary transmission medium can redefine how the internet functions, significantly enhancing the global capacity for communication and paving the way for new data network architectures.
enquanto isso no Brasil temos internet de 500 gb e as operadoras não são obrigadas a entregar a velocidade contratada. A nossa internet é uma tartaruga manca
