What is the basic type of Types of Optical Fibers?

The type of the fibre depend upon the material that use, refractive index of the fibre and mode of propagation of light. Here is the brief info about the types of the optical fibre cable : - 

Based On Refractive Index

• Step Index Fibers

• Step Index Fibers

Based On Material

• Plastic Optical Fibers

• Glass Fibers

Based On Propagation of Light

• Single-Mode Fibers
