Open Line System Global Market Report 2025

The open line system market size has grown rapidly in recent years. It will grow from $2.54 billion in 2024 to $2.82 billion in 2025 at a compound annual growth rate (CAGR) of 10.7%. The growth during the historic period is driven by rising demand for high-speed internet connectivity, increased adoption of broadband infrastructure, growing use of video streaming services, higher enterprise data traffic, and expanded telecom infrastructure investments.

The open line system market size is expected to see rapid growth in the next few years. It will grow to $4.18 billion in 2029 at a compound annual growth rate (CAGR) of 10.4%. The growth in the forecast period is supported by greater adoption of cloud-based services, rising demand for low-latency applications, expanded deployment of fifth-generation networks, growth of smart city projects, and increased investments in hyperscale data centers. Key trends in the forecast period include advancements in hollow-core fiber, development of photonic integrated circuits, innovations in silicon photonics transceivers, progress in artificial intelligence-based network optimization, and integration of digital twinning for network management.

The increasing rollout of 5G networks is expected to drive the growth of the open-line system market. 5G networks, representing the fifth generation of mobile communication technology, offer faster data speeds, ultra-low latency, higher network reliability, and the capacity to connect a massive number of devices simultaneously. The expansion of 5G networks is primarily fueled by growing demand for high-speed mobile broadband, as consumers and enterprises require faster and more reliable connectivity for streaming, cloud computing, and smart device applications. Open-line systems support 5G networks by providing flexible, high-capacity, and low-latency optical transport infrastructure that efficiently handles massive data traffic, enables ultra-reliable low-latency communications, and facilitates seamless network slicing for diverse 5G services. For example, in July 2024, according to 5G Americas, a US-based telecommunication organization, global 5G connections reached nearly 2 billion in the first quarter of 2024, adding 185 million new subscriptions, with projections estimating 7.7 billion connections by 2028. The increasing rollout of 5G networks is therefore propelling the growth of the open-line system market.

Key companies in the open-line system market are focusing on innovations such as zero-touch provisioning to simplify deployment, reduce operational complexity, and enable rapid network scaling. Zero-touch provisioning (ZTP) automatically configures and deploys network devices without manual intervention, reducing setup time, minimizing errors, and simplifying network management. For instance, in March 2025, Adtran Inc., a US-based telecommunications company, launched the FSP 3000 IP Open Line System (OLS), a compact, plug-and-play solution designed to streamline optical networking. The platform features zero-touch provisioning, automated span equalization, full-spectrum monitoring, and fiber assurance, enabling capacity expansion from 400G to 1.6T per wavelength. By integrating automation and intelligence into a 1RU chassis, the FSP 3000 IP OLS reduces operational complexity, accelerates deployment, and allows service providers and enterprises to efficiently scale networks in response to surging AI and data center traffic while ensuring high reliability, improved network visibility, and seamless integration with existing infrastructure.

In February 2025, Nokia Corporation, a Finland-based technology company, acquired Infinera Corporation for an undisclosed amount. The acquisition allows Nokia to strengthen its position in optical networks by combining scale, advanced technology, and expertise to accelerate product development, expand in webscale and data center markets, and enhance its global customer base. This enables network operators to meet the rapidly growing demands of the AI era while improving innovation and operational efficiency. Infinera Corporation is a US-based telecommunications company specializing in open line system solutions, as well as metro, long-haul, and subsea networks.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.
