Hollow core fiber has been developed for more than 20 years and is recognized as the most revolutionary innovation in photonic crystal fiber technology. In this kind of photonic crystal fiber, light can be confined to a hollow core in the center by generating a photonic band gap in the fiber cladding. Its advantage is that the performance of the fiber is not limited by the material properties of the core. Through reasonable design, the hollow fiber can realize the transmission process of more than 99% of the light in the air, thus greatly reducing the influence of the material properties of the fiber on the optical properties and optical properties. In many applications, it has advantages over traditional optical fiber, and is likely to replace traditional optical fiber in the future.

    During OFC2022, Lumenisity, a provider of hollow fiber optic cable solutions, announced the launch of the record-breaking hollow fiber DNANF. It has lower optical loss and can provide larger optical transmission capacity, longer coverage and wider spectral bandwidth. The transmission attenuation of this technology is also the lowest of all hollow fibers.

    Hollow core anti-resonant fiber is the future development direction in the field of communication, which can be used for dense wavelength division multiplexing (DWDM) applications over networks of more than 10km. Based on hollow core fiber, we can do a lot of laser applications, including gas supercontinuum output, such as Raman effect optical frequency comb, including high energy laser transmission for laser processing, laser cutting, laser ignition and other applications.

    However, new fiber brings the new challenge on fiber fusion splicing. Shinho has accumulated 20 years of technical experience, and continue to pay attention to the latest technology updates in the industry.The S-12PM series fusion splicers have already being applied to PM,LMA,MCF and PCF splicing solution. Shinho will continue to pay attention to and research solutions for hollow core fiber fusion splicing.
