Bend-insensitive fiber cables are special types of cables designed to keep light inside the cable even when the cables are bent more than usual. Optical fiber is sensitive to stress, particularly bending. When stressed by bending, light in the outer part of the core is no longer guided in the core of the fiber so some is lost, coupled from the core into the cladding, creating a higher loss in the stressed section of the fiber. If you put a. to design a kind of bend-insensitive fiber. This article, with the loss of optical fiber, mainly describes the current popular structure design of bend-insensitive fiber and the influence of bending on the mechanical strength of fiber and introduces some ap es may lead to the fiber should not be. These kinds of fibers are also known as Bend-Insensitive (BI) or Reduced-Bend-Insensitive (RBI) fiber cables.
