The optical fiber is one of the most important key technologies that support the current information technology (IT) era. Optical fibers are now widely used not only as an excellent transmission medium for optical communication but also as optical functional devices, such as optical amplifiers. Both optical fibers and their manufacturing technologies have evolved dramatically toward higher performance and improved productivity. Their applications have also been expanded from optical communication to a variety of fields, such as optical sensors. This article reviews various aspects of optical fibers: structures & materials, fabrication techniques, optical characteristics & reliability, and applications.
