Japanese researchers have achieved a groundbreaking success in data transmission technology. In the study, 1.02 petabits per second of data transmission was achieved over a standard-thick optical fiber cable. This speed means that approximately 10,000 4K resolution movies can be transferred in a single second. The result was recorded as one of the highest speeds achieved in the field of optical communication to date.

The Japanese managed to break a record in data transmission speed

A standard optical fiber cable with a diameter of only 0.125 mm was used in the experiment. However, the structure of this fiber was not ordinary. A special fiber consisting of 19 cores was designed. While each core served as an independent signal carrier, the data signal was looped 21 times by passing through these cores. With this method, uninterrupted data transmission was achieved over a total of 1808 kilometers of fiber line.

A special receiver that can collect 19 separate signals simultaneously was used at the data exit point. The received signals were analyzed by digital processors to calculate the total data rate reached per second. The 1.02 petabits/second value achieved with this method showed that ultra-high speeds are possible not only in short distances but also in long fiber lines.

This success achieved set a new record not only in terms of speeds per second, but also in the “bit/second × kilometer” metric, which expresses the product of speed and distance. The experiment achieved a total of 1.86 exabit-seconds/kilometers, an unattained value.

The researchers state that this technology can play a critical role especially for data traffic, which is expected to increase rapidly in the post-5G period. So what do you think about this subject? You can share your views with us in the comments section below.
