Japanese researchers have successfully developed an internet communication channel capable of delivering speeds up to a million gigabits per second across a significant distance.
This remarkable speed was achieved through the use of a 19-core optical fiber. While faster speeds (reaching up to 1.7 million Gbps) have been previously demonstrated, those records were typically set over much shorter distances (e.g., 63.5 km). The recent achievement is notable for transmitting a million gigabits per second over an impressive 1,800 km. This experiment carries considerable practical implications, suggesting that such a high-capacity line could be viable for future commercial telecommunications.
To visualize this speed, a connection operating at a million gigabits per second could theoretically download approximately 10,000 4K resolution movies in just one second. The research indicates that it is feasible to substantially enhance the data transfer capacity of existing network infrastructures without necessitating a complete overhaul or the development of entirely new technological paradigms from the ground up.
