China makes history in data centers by achieving fiber optic transmission at 1 terabyte per second over 1,200 kilometers.
China recently broke the world record for data transmission, surpassing its competitors in the process. The Asian nation reached speeds of 1 terabyte per second over 1,200 kilometers, while a group of Australian scientists reached a connection speed of 2 megabits per second over 16 kilometers.
Under the direction of Professor Lilin Ye, the Shanghai Jiao Tong University project has defied convention in order to guarantee optimal security along the entire route. Existing systems expose the optical signal by encrypting messages at the software level. By encrypting the signal itself, a technology called Integrated Encryption and Communication (IEAC) safeguards the message.
China has not only attained previously unheard-of data transfer speeds, but it also guarantees the highest level of security. The light signal itself is encrypted by the system, making message interception nearly impossible.
Geometric Constellation Shaping (GCS) is a technique that makes it possible to encrypt messages by randomly changing the optical pattern of light. The signal might appear to a prospective spy as continuous noise, but they would never be able to figure out the precise key.
These messages involve artificial intelligence. For every batch of data, AI generates a unique light pattern using random numbers that can only be decoded by infrastructure interceptors.
In preliminary tests, the Asian nation not only managed to attain incredibly low connection speeds of 1 terabyte per second, but it also achieved an error rate that was almost zero. In order to test the system, researchers simulated typical network conditions like optical noise, nonlinearity, and dispersion.
