What the fiber optics consist of ?

Fiber consists of Silica as material and core and cladding as structure of the material.

Light travels through core surrounded by cladding which prevents the light to go out of the core/fiber.

Optical fiber consists of a core and a cladding layer,

Fiber optics consists of fiber core, coating ,cladding . it is covered by the buffer tubes & transmits light from Transmission end to the Receiver end . 

many core type is available and method of transfare data as simplex channel or Duplex.

it depends on the activity.

Optical fiber consists of a layers including core & cladding.

Fiber optics consists of fiber core, coating & cladding covered by the buffer tubes; the core is made up of glass type substance that transmits light to the end side. 

Fiber core is consists of colour coating, cladding and core. All these will make up of a core inside the buffer tubes.

The most modern and efficient data transmission technology available today. The signal, instead of transit in normal copper cables, passes through a new infrastructure composed of very thin glass fiber filaments enclosed in a casing.
