Description:
The buffer and coating are the material that surround the glass
fiber. They are responsible for protecting the fiber strands from
physical damage.
The core is the cylinder consisting of glass fiber which carries
information in the form of light pulses.
The cladding is a material that provides internal reflection so
that the light pulses can travel the length of the fiber without
escaping from the fiber.
