Our country breaks the record for optical communication transmission.

According to the Science and Technology Daily, on the 24th, it was learned from the China Information and Communication Technology Group Optical Communications Technology and Network National Key Laboratory that the laboratory, in collaboration with the Peng Cheng Laboratory and Finisar Optic Fiber Technology Co., Ltd., has achieved important technological breakthroughs in the field of ultra-large-capacity real-time optical transmission. For the first time, a real-time bidirectional transmission capacity of 2.5 petabits per second was achieved on a 10.3 km 24-core single-mode optical fiber. This is another key breakthrough in the direction of "ultra-large capacity, ultra-high speed, ultra-long distance" optical transmission achieved by China Information and Communication Technology Group.
