Hollow-core Anti-Resonant Fibre and Adapter

Request a Quote

Breaking away from traditional solid-core fibre transmission mediums, hollow-core anti-resonant fibres (also known as hollow core fibres) feature an air-guiding waveguide structure. They are characterized by low latency, wide transmission bandwidth, low loss, and low nonlinearity, making them ideal for high-capacity, high-speed, low-latency, and long-distance optical transmission networks. These networks are particularly well-suited for various fields, such as computing power networks, AI data centers, dedicated lines for industrial finance, and electric power networks. Additionally, hollow core fibres exhibit ultra-low Rayleigh scattering, low dispersion, large effective area, tunable wavelength, and higher laser damage thresholds. These properties render them highly promising for applications in high-power laser transmission, ultraviolet to mid-infrared optical transmission, pulse compression, quantum transmission, and gas sensing.

    Hollow Core Fibre Adapter

    A hollow core fibre adapter is designed to connect hollow core fibres with single-mode fibres. Featuring a modular packaging design, the adapter enables optical power coupling between hollow core fibres and single-mode fibres with low insertion loss and low return loss. It allows for direct connection of hollow core fibres to existing transmission systems, enhancing user convenience. Furthermore, when used in conjunction with hollow core fibre cables, the adapter contributes to the construction of a complete low-latency communication system.
