The polarization preserving fiber (PPF) with boron-doped stress bars is a specialized optical fiber designed to maintain the polarization state of light during transmission. This type of fiber is essential for applications where polarization integrity is critical, such as in telecommunications, fiber optic sensing, and interferometry. The boron-doped stress bars within the fiber struc... https://www.openpr.com/news/3699330/polarization-preserving-fiber-boron-doped-stress-bar-market
