These are made of long-chain polymers which are modified by a chemical process to enable polymerization to form fibres. We can divide these fibres into two groups: protein (animal) and cellulose (plant) fibres. Types of Optical Fibers. One of the basic ways to classify fiber is by its origin, and this is indeed the most commonly employed method. The types of optical fibers depend on the refractive index, materials used, and mode of propagation of light. sector. Classification and properties.
