What are the classifications of optical fiber communication materials
Today, optical fibers are used in a wide range of applications, from telecommunications and data centers to aerospace and medical devices. They transmit light signals over long distances with minimal loss. Each optical cable is constructed using a precise combination of optical fibers, strength members, buffer tubes. Fiber Optics or Optical Fiber is a technology that transmits data as a light pulse along a glass or plastic fiber. An Optical Fiber is a cylindrical fiber of glass that is hair-thin in size or any transparent dielectric medium. The fiber which is used for optical communication is waveguides made of.
