CTOnews.com, October 9, August 10, the Xiguang-1 series with one arrow and five stars was launched from the Jiuquan Satellite launch Center aboard the Ceres-1 Yao Seven carrier rocket. The spaceborne optical switch independently developed by Xi'an Institute of Optics and Machinery of the Chinese Academy of Sciences was carried out as one of the important payloads to carry out the space verification of China's first high-speed optical switching technology.

Recently, the good news from Xi'an Institute of Optics and Mechanics of the Chinese Academy of Sciences has come that a number of technical verification tests have been carried out on schedule. The ground test results show that the functions of the spaceborne optical switch are normal, and the hyperspectral image information is complete. After downloading, the ground analysis reached the level of "zero error code" and "zero packet loss", achieving all the set goals, and the test of high-speed optical switching technology in orbit was a complete success.

According to reports, building a global spatial large-capacity optical network is the only way to realize the interconnection and sharing of massive user information in the future. The spaceborne optical switching technology breaks through the traditional technical barriers and processes the optical signals directly in the optical domain without the need for "optical / electrical" and "electrical / optical" conversion, which effectively solves the problem of "electronic rate bottleneck" in electrical switching processing. it has the advantages of intelligent and dynamic network resource allocation, transparent communication system and protocol, flexible network expansion and low power consumption, and is the overpass of space "expressway network". It is the core technology of spatial massive data distribution, forwarding and other processing.

Xi'an Institute of Optics and Machinery, Chinese Academy of Sciences, said that the success of this experiment is another important on-board application made by the systematic development of high-speed space laser communication in Xi'an Optical Machinery Institute after the on-orbit verification of intersatellite laser communication technology was realized on May 20, 2022. It has once again consolidated the core technical reserves and equipment support for the construction of large-capacity space optical networks in China in the future.

CTOnews.com Note: Xi'an Institute of Optics and Machinery, Chinese Academy of Sciences. In order to develop China's nuclear weapons and solve the problems of high-speed photography and radiation-resistant optical materials necessary for nuclear explosion tests, the second Machinery Department of the State and the Chinese Academy of Sciences have decided to establish a research institute in Xi'an to undertake the optical measurement task of nuclear explosion tests.

On March 27, 1962, the Xi'an Institute of Atomic Energy of the former Chinese Academy of Sciences, the Institute of Applied Optics of the Shaanxi Branch of the Chinese Academy of Sciences, most of the personnel of the Institute of Machinery and Automation were merged, and the Xi'an Branch of the Institute of Optics and Precision Machinery of the Chinese Academy of Sciences was established. It was renamed as "Xi'an Institute of Optics and Machinery of the Chinese Academy of Sciences" on December 27, 1965, and changed its name to "the 1503 Research Institute of the Chinese people's Liberation Army" in January 1968. It has been renamed as "Xi'an Institute of Optics and Precision Machinery, Chinese Academy of Sciences". Now it has developed into a comprehensive research institute based on strategic high-tech innovation and applied basic research.
