An Overview of Macrobending and Microbending of Optical Fibers

Bending can increase the attenuation of an optical fiber by two mechanisms: macrobending and microbending. Some bending is of course unavoidable, e.g., shipping and storage, optical cable manufacturing and installation as well as fiber termination and deployment. Understanding the fundamental nature of attenuation increase with bending enables development of products and usage conditions to maintain the initial superior attenuation of fiber.
