Fibre optics refers to a technology and product category rather than a specific brand, widely used in telecommunications, data transmission, and networking industries. Key companies in this sector include Corning (USA), Prysmian Group (Italy), and Fujikura (Japan). These firms specialize in manufacturing optical fibers, cables, and related components, enabling high-speed data transfer over long distances with minimal loss. Applications span telecommunications, medical devices, and industrial sensing. Products range from single-mode and multi-mode fibers to fiber-optic connectors and amplifiers, serving global infrastructure and connectivity needs.
