As we all know, fiber optic cable has been widely used in the telecommunication area. During fiber cable installation and maintenance, cable bending can’t be avoided. But optical fiber cable is very sensitive to bending. When the fiber cable is bent, some of the light in the core will be lost, creating impact on fiber links performance. So bend insensitive (BI) fiber cables are very useful in fiber optical network. To know more details about this kind of fiber cable, continue to read this tutorial.
