초록

The world's first 5G commercial service started in Korea in April 2019. This makes us proud of our status as an ICT powerhouse, and of the domestic optical network industry ecosystem that has served as a lever to make this significant leap forward in technological and industrial competitiveness. Above all, Japan's trade regulations on core parts and the COVID-19 pandemic have led to new changes across cultures, societies, and economies, and 5G networks have become important. The relevant technology for core material parts is a major concern not only of a few industries, but an entire section of society in terms of national competitiveness. In this article, we discuss the role of industries through the analysis of prospects of optical component technology with regard to the changes in the economic and social paradigm caused by the COVID-19 pandemic and Japan's export regulations.
