Optical fiber is made is made of glass or plastic and transmits signals in the form of light.
Transmission of light signal in optical fiber is based on the phenomenon of total internal reflection.
An optical fiber cable has a cylindrical shape and consists of three concentric sections
- the core
- the cladding
- the jacket
The core is the innermost section and consists of one or more very thin strands or fibers made of glass or plastic.
Each fiber is surrounded by its own cladding, a glass or plastic coating that has optical properties different from those of the core.
The outermost layer, surrounding one or a bundle of cladded fibers(jacket). The jacket is composed of plastic and other material layered to protect against moisture, crushing and other environmental damages.
