About This Webinar
Hollow-core fibers are reshaping optical technology, combining ultralow latency and unlocking applications in data centers, quantum communications, sensing, and high-power laser delivery. But moving from prototypes to stable, repeatable production requires dedicated manufacturing systems. This webinar explores the complete hollow-core fiber manufacturing chain and the Nextrom machinery that enables it. Beginning with preform manufacturing systems, it examines equipment designed to produce high-quality structures for hollow-core geometries. The webinar will then focus on the fiber draw tower, where precise control of furnace temperature, capstan tension, and internal gas pressure is essential. Finally, it will cover how proof testing equipment ensures the mechanical strength and long-term reliability of the hollow-core fiber. Along the way, the webinar will show how Nextrom’s advanced process control and automation features improve yield, reduce defects, and enable consistent fiber quality.
Participants will gain a clear picture of how Nextrom’s Specialty Fiber machinery, covering preform, draw, and proof testing equipment, provides the complete solution needed to manufacture hollow-core fibers from a concept to real-world deployment in communications, sensing, and specialty fiber markets.
Who should attend:
This webinar is ideal for fiber manufacturers, R&D engineers, and operators working on optical and specialty fibers, as well as industry leaders and decision-makers in telecommunications, sensing, and laser markets who are interested in manufacturing solutions for hollow-core fibers. It will also benefit process engineers, production managers, and specialists involved in specialty fiber manufacturing, along with telecom network and data center professionals seeking ultralow-latency, high-capacity solutions. In addition, photonics and quantum researchers exploring new approaches to hollow-core fiber manufacturing will gain valuable insights.
