Hollow-Core Fiber Market Report 2026

The hollow-core fiber market size has grown rapidly in recent years. It will grow from $1.23 billion in 2025 to $1.43 billion in 2026 at a compound annual growth rate (CAGR) of 16.4%. The growth in the historic period can be attributed to reliance on traditional solid-core fibers, high transmission losses, limited long-distance bandwidth, signal distortion in conventional fibers, low adoption in precision sensing.

The hollow-core fiber market size is expected to see rapid growth in the next few years. It will grow to $2.6 billion in 2030 at a compound annual growth rate (CAGR) of 16.1%. The growth in the forecast period can be attributed to rising demand for high-speed optical communication, adoption in aerospace and defense, growth in healthcare and manufacturing sensing applications, expansion of long-distance telecommunication networks, development of low-loss and high-power hollow-core fibers. Major trends in the forecast period include ultra-low loss transmission, high-bandwidth long-distance communication, advanced optical sensing applications, ultrafast signal transmission, precision signal guidance.

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, according to the UK Parliament’s House of Commons Library, a UK-based government administration, as of January 2024, gigabit-capable broadband reached 78% of UK premises, increasing from 72% in January 2023 and 64% in January 2022. Therefore, the rising demand for high-speed internet connectivity is driving 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 January 2023, Microsoft, a US-based provider of software, cloud computing, and technology solutions, acquired Lumenisity Limited for an undisclosed amount. Through this acquisition, Microsoft aims to enhance its technological capabilities in advanced fiber optic solutions, supporting high-speed data transmission and next-generation network infrastructure. Lumenisity Limited is a UK-based telecommunications company that offers hollow-core fiber (HCF) with a proprietary design that provides multiple advantages over traditional solid-core fiber.

Tariffs have affected the hollow-core fiber market by increasing the cost of importing specialized fibers such as photonic bandgap fibers, anti-resonant fibers, and other advanced optical materials. Telecom, IT, healthcare, aerospace, and manufacturing segments in Asia-Pacific regions, including China, India, and Taiwan, are most impacted due to their dominance in fiber manufacturing. Higher tariffs have raised deployment and procurement costs, slowed project timelines, and posed challenges for smaller enterprises and research organizations. Companies are mitigating these effects by sourcing locally, investing in advanced manufacturing processes like draw tower and extrusion methods, and developing custom hollow-core fiber solutions. On the positive side, tariffs are driving innovation in low-loss, high-power transmission, and dispersion-managed fibers, ultimately improving long-term performance, efficiency, and reliability of optical networks.

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. Key end users include telecom and information technology (IT), healthcare, manufacturing, aerospace and defense, and other sectors.
