C114 News on April 21st noon (Shu Yunwen) With the deep coverage of 5G networks and the expansion of data center scale, the physical performance and spatial adaptability of fiber optic cables are becoming a major bottleneck in network infrastructure construction. Traditional optical fibers are limited by their outer diameter size, making it difficult to meet the complex requirements of tight pipeline resources and increased wiring density. Targeting this pain point, C114 has learned that Hengtong Optoelectronics has recently officially launched a series of small-diameter fiber products, providing the industry with a new generation of high-density, lightweight, and strong resilience solutions with fiber diameter specifications ranging from 170μm to 200μm and self-developed technology throughout the entire chain.
Public information shows that the outer diameter of traditional optical fibers is mostly concentrated at 250μm. In high-density scenarios such as air blown micro cables and data centers, the utilization rate of wiring space has approached the physical limit.
The thin diameter fiber optic series products launched by Hengtong Optoelectronics this time include BendCom Mini-200μm LMini-180μm,SMini-170μm, By optimizing the wire drawing process, the overall diameter has been significantly reduced compared to traditional specifications; Meanwhile, by using specialized high-performance resin materials for coating protection, the optical fiber still maintains excellent parameter performance even with reduced size. In addition, this series of optical fibers not only increases the cable laying capacity and reduces cable weight in limited space, but also improves construction efficiency and reduces costs.
The ultimate compression of fiber diameter poses a severe challenge to the mechanical performance and reliability of optical fibers. Hengtong Optoelectronics relies on a performance testing platform covering optical rods, optical fibers, and coatings, as well as a self-developed system for the entire chain. Through continuous iteration and optimization, we have developed a wire drawing coating technology and coating materials specifically designed for small-diameter optical fibers.
Thanks to this, the performance of Hengtong's thin diameter fiber series products meets or exceeds industry standards and national standards. The typical concentricity deviation of the outer coating reaches 2μm, and the typical concentricity deviation of the inner coating reaches 1μm. The fiber has excellent bending resistance and is characterized by easy peeling and high strength.
From fiber to household to miniaturized optical devices, Hengtong thin diameter fiber can be widely used in various fields: in the application scenarios of ultra-fine air blown micro cables and ultra-high density optical cables, this smaller coating outer diameter can meet the demand for denser cores in smaller spaces, improve space utilization and information data transmission volume, and maintain stable transmission performance; In miniaturized devices, it can easily shuttle through them, saving valuable space resources while still maintaining low loss and high stability, providing support for cutting-edge technology.
Third party research institutions such as LightCounting analyze that fiber miniaturization is an inevitable choice to cope with the surge in global data traffic. Hengtong Optoelectronics' product iteration this time may promote the large-scale application of high-density optical cables in urban area networks, data centers, and special industrial fields. However, some experts also remind that reducing fiber diameter may require higher coupling accuracy for optical modules, and collaborative innovation in the industrial chain still needs to be strengthened.
