South Korea Submarine Cable Systems Market (2025-2030)

The study involved four major activities in estimating the current size of the submarine cable systems market. Exhaustive secondary research was conducted to gather information on the market, adjacent markets, and the overall submarine cable system landscape. These findings, assumptions, and projections were validated through primary research involving interviews with industry experts and key stakeholders across the value chain. Both top-down and bottom-up approaches were utilized to estimate the overall market size. Subsequently, market breakdown and data triangulation techniques were applied to determine the sizes of various segments and subsegments. Two key sources, secondary and primary, were leveraged to conduct a comprehensive technical and commercial assessment of the submarine cable systems market.

Secondary Research

The secondary research process referred to various secondary sources to identify and collect necessary information for this study. The secondary sources included annual reports, press releases, and investor presentations of companies; white papers; journals and certified publications; and articles from recognized authors, websites, directories, and databases. Secondary research was conducted to obtain key information about the industry’s supply chain, the market’s value chain, the total pool of key players, market segmentation according to the industry trends (to the bottom-most level), regional markets, and key developments from market- and technology-oriented perspectives. The secondary data was collected and analyzed to determine the overall market size, further validated by primary research.

Primary Research

Extensive primary research was conducted after gaining knowledge about the current scenario of the submarine cable systems market through secondary research. Several primary interviews were conducted with experts from the demand and supply sides across four major regions—North America, Europe, Asia Pacific, and RoW. This primary data was collected through questionnaires, emails, and telephonic interviews.

Note: Three tiers of companies have been defined based on their total revenue as of 2024: tier 3: revenue less than USD 500 million; tier 2: revenue between USD 500 million and USD 1 billion; and tier 1: revenue more than USD 1 billion. Other designations include sales managers, marketing managers, and product managers.

Market Size Estimation

Both top-down and bottom-up approaches were used to estimate and validate the total size of the submarine cable systems market. These methods have also been used extensively to estimate the size of various subsegments in the market. The following research methodology was used to estimate the market size:

• Major players in the industry and markets were identified through extensive secondary research
• The industry’s value chain and market size (in terms of value) were determined through primary and secondary research processes
• All percentage shares, splits, and breakdowns were determined using secondary sources and verified through primary sources

Data Triangulation

After arriving at the overall size of the submarine cable systems market using the market size estimation process explained above, the total market was split into several segments and subsegments. Data triangulation and market breakdown procedures were employed, wherever applicable, to complete the overall market engineering process and arrive at the exact statistics for all segments and subsegments of the market. The data was triangulated by studying various factors and trends from the demand and supply sides. The market size was also validated using top-down and bottom-up approaches.
