ABOUT US

Linfiber Technology (Nantong) Co., Ltd.

Linfiber Technology (Nantong) Co., Ltd. is committed to the research, development, production, sales, and industrial application of high-performance hollow-core optical fibers. Leveraging the strong R&D capabilities of the Microstructured Optical Fiber team at Jinan University, the company owns multiple core patents for hollow-core optical fibers. It has mastered key processes and core technologies for the production and preparation of hollow-core optical fibers and cables, with autonomous innovation capabilities spanning the entire chain from fiber design, fabrication, splicing, cabling, to performance characterization and system monitoring. This facilitates the implementation of comprehensive solutions based on hollow-core optical fibers for optical communication, sensing, and laser applications.

INTRODUCTION TO HOLLOW CORE FIBER

Fiber optic technology is evolving from the "1.0 era," represented by traditional silica fibers, to the "2.0 era," characterized by hollow-core fibers. Traditional silica fibers are facing a series of challenges due to material limitations, such as the "channel capacity crush," "high-power laser damage," and "performance degradation under irradiation." Hollow-core fibers, using air as the guiding medium, provide an ideal environment for light transmission with low nonlinearity, low dispersion, low loss, and low latency. This technology offers revolutionary breakthroughs for applications in fiber-optic communication, lasers, nonlinear optics, quantum technology, and sensing.

Ultra-low loss

The loss of hollow-core fibers has reached the level of <0.11 dB/km(OFC 2024 Th4A.8), surpassing the loss levels of any fiber made from current materials. This significantly reduces the number of amplifiers and transceiver modules needed, providing a new solution for long-distance transmission.

Low dispersion

Hollow-core fibers exhibit near-zero dispersion values and dispersion flatness, which can significantly reduce DSP complexity, simplify receiver architecture, and lower system costs and power consumption.

Ultra-low Latency

Compared to traditional silica fibers, hollow-core fibers offer a latency improvement of over 1.5 μs/km, bringing new vitality to applications in finance, AI clusters, and other fields.

Ultra-low nonlinear effect

The nonlinear coefficient of hollow-core fibers is three orders of magnitude lower than that of traditional solid-core fibers. This enables high-fidelity, distortion-free transmission over long distances, providing an effective solution to the nonlinear shannon limit issue.

APPLICATIONS

High-Capacity, Low-Latency Fiber Optic Communication Solution

Hollow-core fibers (HCF) have emerged as a groundbreaking technology in high-capacity, low-latency fiber optic communication solutions. By guiding light through a hollow core, these fibers significantly reduce the latency by 31% compared to traditional solid-core fibers, enabling faster data transmission over long distances. The unique structure of HCFs also minimizes signal loss and dispersion, ensuring high data integrity and transmission quality. As a result, HCFs are particularly well-suited for applications that demand ultra-fast, reliable communication, such as data centers, high-frequency trading networks, and advanced telecommunications infrastructure. Their ability to support higher bandwidths with lower latency positions hollow-core fibers as a critical component in the evolution of next-generation communication systems.

High Power Laser Transmission Solutions

Hollow-core fibers (HCF) are revolutionizing laser transmission applications, offering unmatched performance for a variety of laser types. HCFs are particularly beneficial for high-power ultra-short pulse lasers, where their unique design helps mitigate nonlinear effects and prevent damage that typically occurs in solid-core fibers. They also excel in transmitting narrow linewidth lasers with minimal spectral broadening, ensuring precision and stability. Moreover, HCFs are adept at handling a broad range of wavelengths, from UV to visible to mid-infrared, providing versatility across numerous applications. To achieve polarization-maintaining (PM), specially designed PM-HCFs maintain the integrity of the polarization state over long distances, which is crucial for applications requiring high polarization purity. This combination of capabilities makes HCF an ideal choice for advanced laser transmission needs.
