Hollow-Core Fiber Global Market Report 2025

The hollow-core fiber market size has grown rapidly in recent years. It will grow from $1.05 billion in 2024 to $1.23 billion in 2025 at a compound annual growth rate (CAGR) of 16.6%. The growth in the historic period is attributed to increasing adoption of high speed data transmission, rising demand for long haul communication networks, growing use in scientific research applications, increasing reliance on cloud computing services, and expanding deployment in defense and aerospace communication systems.

The hollow-core fiber market size is expected to see rapid growth in the next few years. It will grow to $2.24 billion in 2029 at a compound annual growth rate (CAGR) of 16.2%. The growth in the forecast period is driven by rising demand for 5G networks, increased investments in telecom infrastructure, expansion of cloud computing and data centers, growth in industrial automation, and government efforts to promote digital connectivity. Key trends in the forecast period include advancements in fiber fabrication technology, innovations in low loss transmission designs, increased investment in optical communication infrastructure, progress in hybrid fiber technologies, and developments in scalable production techniques.

The increasing demand for high speed internet connectivity is expected to drive the growth of the hollow core fiber market going forward. High speed internet connectivity refers to broadband services that offer fast data transmission capabilities, enabling seamless digital communication and data transfer. Demand is rising due to accelerated digital transformation across industries, as remote work, cloud computing, and streaming services require robust bandwidth infrastructure to support growing data consumption. Hollow core fiber supports high speed internet connectivity by using air filled cores that allow light signals to travel faster with significantly reduced latency and signal loss compared to conventional solid core fibers, providing the ultra fast, low latency infrastructure essential for high bandwidth applications and next generation telecommunications networks. For example, in November 2024, the UK Parliament’s House of Commons Library reported that as of January 2024, gigabit capable broadband covered 78 percent of UK premises, up from 72 percent in January 2023, 64 percent in January 2022, and 36 percent in January 2021. Therefore, rising demand for high speed internet connectivity is fueling the growth of the hollow core fiber market.

Key companies in the hollow core fiber market are focusing on developing innovative solutions such as low loss anti resonant hollow core fibers to enable ultra fast, low latency, and high capacity optical networks. Low loss anti resonant hollow core fibers (AR HCFs) are optical fibers with a hollow core that guides light through air rather than solid glass, reducing scattering and absorption. This helps lower signal loss, reduce latency, minimize dispersion, and allow higher power, long distance, high speed data transmission. For instance, in September 2024, Linfiber Technology (Nantong) Co., Ltd., a China based company, launched its LinearCore hollow core fiber cable, featuring an innovative anti resonant hollow core fiber (AR HCF) structure with a loss of 0.5 dB/km in the C+L band. The cable delivers about 30 percent lower latency compared to standard silica glass fibers and supports ultra high capacity transmission, enabling more efficient long distance, high speed data transfer with minimal signal degradation. LinearCore also incorporates advanced connector and splicing technologies, including SMF28 HCF connectors and HCF HCF splicing techniques, ensuring low connection loss (less than 0.3 dB) and reliable field deployment. Its design allows higher input power, reduces the need for repeaters and amplifiers, and simplifies optical dispersion and nonlinear compensation, lowering energy consumption and overall system cost.

In December 2022, Microsoft Corporation, a US based technology and cloud computing company, acquired Lumenisity Limited for an undisclosed amount. Through this acquisition, Microsoft aims to leverage Lumenisity Limited’s hollow core fiber technology to improve the speed, security, and efficiency of its cloud infrastructure, enabling it to better meet customer demands for low latency, high bandwidth, and secure connectivity. Lumenisity Limited is a UK based telecommunications company specializing in hollow core fiber solutions.

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.

A hollow core fiber is a type of optical fiber in which light is guided mainly through a hollow, air filled core rather than a solid glass core. This design significantly reduces light absorption and scattering, resulting in lower transmission losses and enabling the transmission of high bandwidth signals over long distances. Hollow core fibers are used in advanced optical communication, high precision sensing, and ultrafast signal transmission applications due to their efficient light guidance and minimal signal distortion.

The main types of hollow core fiber include photonic bandgap fibers, anti resonant fibers, and other specialized hollow core fibers. Photonic bandgap fibers are specialized optical fibers with a periodic structure that guides light through a hollow core, allowing low loss, high power, and high performance transmission. They are manufactured using materials such as silica, polymer, and others, and produced through processes including extrusion, draw tower, lasing, sintering, and other advanced techniques.
