From what optical fiber is made?

optical fiber is made up of thin glass (sillica) or plastic which is thicker than human hair. optical fibers have a transparent core which is covered by a transparent cladding material whose refraction index is less than the core.

Optical Fiber is made of Silica. Now a days polymer are being used as an alternative for Silica.

Plastic and glass materials are used for optical fiber manufacturing.

Fiber can be made single mode or multimode.

Optical fibers are made of extremely pure optical glass.

The core of optical fiber is usually made of Silica, cladding is made of many materia

Optical fibers are almost always manufactured using Silica, but still some other materials are used depending on the applications.Fluorozirconate, Fluoroaluminate, and Chalcogenide glasses are also used as well as crystalline materials like sapphire, for long wavelengths applications.
