데이터 고속도로의 시대: 춘천의 스마트 혁신과 글로벌 광통신 시장의 대전환 > K-wave Trends

Chuncheon City has made an administrative decision to invest 11.5 billion won over the past two years to build a 210km self-communication network connecting the entire city. By moving away from the leased line system that depended on external communication service providers in the past and switching to a system in which the city directly owns and operates the infrastructure, annual communication costs were significantly reduced from KRW 2.3 billion to KRW 1.1 billion, which is about half. Beyond simply saving the budget, the operation center, which will be fully operational starting in October, will serve as a control tower that reliably transmits key data for city operations such as disaster detection sensors, CCTV, and intelligent transportation systems (ITS). This heralds a qualitative leap in smart city services that citizens can directly experience by resolving the information gap by expanding the network to areas outside the city center such as Seomyeon and Dongsan-myeon in the future.

If the case of Chuncheon shows efficient digital transformation at the local government level, a 'super cycle' is unfolding in the global market where the explosive growth of AI data centers is driving demand for optical cables. Domestic specialized companies such as Mercury recently participated in 'ANGA COM 2026', Europe's largest broadband exhibition held in Germany, and attracted attention from the global market by demonstrating high-depth optical cable technology that can reliably handle high-capacity traffic. In particular, as demand for data center interconnection (DCI) has rapidly increased due to the spread of generative AI services, high-performance optical cables that can carry much more data than before have become an essential element of infrastructure construction. Cooperation discussions with major European telecommunication operators prove that our companies' technological prowess meets global infrastructure standards.

The North American market is also becoming a land of opportunity for Korean companies due to the country-first policy and increased investment in public infrastructure. The 'BEAD' project, a project to build a high-speed Internet network in rural and underprivileged areas promoted by the US government, is expected to invest tens of trillions of won by 2030, and companies such as TMC are already directly benefiting from the 'preferential policy for American products' through local production corporations in the US. In a geopolitical environment where Chinese products are virtually excluded from the market, Korean companies that employ local people and have production systems in the United States are expanding their influence beyond niche markets and into the large-scale public infrastructure market. Demand is so strong that it is difficult to keep up with the number of orders even if the factory operates at full capacity 24 hours a day, proving how solid the physical foundation is required in the era of artificial intelligence.

Technological progress goes beyond the expansion of communication infrastructure and is expanding into the field of next-generation semiconductors that mimic the operating principles of the brain. It is a very encouraging achievement that a joint research team at Sungkyunkwan University and Yonsei University recently developed an optical synapse platform that can strengthen or weaken artificial intelligence memories by controlling the wavelength of light. This attempt to overcome the limitations of existing electrical signal-oriented semiconductors with the speed and efficiency of light is expected to become a core technology for low-power AI chips or autonomous driving visual recognition systems in the future. In this way, technological innovation using 'light', from urban infrastructure to global communication networks and nano-scale semiconductor technology, is becoming a powerful engine that moves our society toward an intelligent digital society.
