It has been three years since the COVID-19 epidemic, and working from home has become the norm for many engineers and scientific research scholars. The software simulation part can be carried out with a computer, but the high-performance test bench cannot be copied home. So when it is necessary to do hardware verification testing, is there a way to expand the connection between engineers and equipment, remotely operate testing equipment, and realize the seamless connection between online and offline work?

With the rapid development of the mobile communication industry, 5G has become a super hot topic in the world. Compared with 2G, 3G, and 4G, the status of 5G in the optical fiber communication industry in the future cannot be underestimated. In the 5G network era, no matter what kind of 5G bearer All solutions are inseparable from 5G communication optical modules. Diversified standard 5G communication optical modules are now considered to be the core technology of the next generation of high-speed and large-capacity optical networks.

【Abstract】 The equipment capacity of wind farms has expanded dramatically as the scale of wind farm construction in China has increased, and the impact on the power grid has become increasingly serious. SVG dynamic reactive power compensation device plays an important role in meeting reactive power, harmonic control, improving power factor and power quality, reducing loss, adjusting voltage and so on.

At the end of April 2021, China Satellite Network Group Co., Ltd. was officially established and formally participated in the global competition for high-speed Internet access services in space. Looking at the world, the Starlink project launched by Tesla founder Elon Musk, the British company OneWeb and the Amazon Group compete with each other in this field. According to incomplete statistics, nearly 30 companies around the world have announced the deployment of satellite Internet constellations, and they plan to launch more than 100,000 satellites.

As countries around the world vigorously develop electric vehicles, auto makers and various standardization organizations have begun to establish technical development standards and define various EV tests.

Lately, the American Foundries Act of 2020 was proposed to the Senate to increase spending in the American semiconductor industry by as much as $25 billion. Not far from today, China also created a $29 billion state-backed fund to invest also in the semiconductor industry.
