SiO2 is non conductive why can it be made as a light conducting fiber

SiO2 itself does not conduct electricity, because optical fibers (i.e., SiO2) contain Si elements, and generally compounds containing Si elements do not conduct electricity. As for why you chose SiO2 as the optical fiber, it is a medium that relies on the total internal reflection in the optical cable to achieve the transmission of information with light. Since light is used for transmission, the medium is required to be as transparent as possible, silica is quartz, the transparency is very high, the cost is low, so it is a good light guide material.

The manufacture of optical fibers is based on the total reflection of light by silica crystals, not by electrical conductivity.

The optical fiber is a transparent glass fiber filament, with a diameter of only about 1 100 m. It is composed of two layers, the inner core and the outer coat, the refractive index of the inner core is greater than the refractive index of the outer coat, and the light enters from one end, and is emitted from the other end after multiple total reflections at the interface between the inner core and the outer coat.

Optical fibers are mixtures and are amorphous. At present, the main component of optical fibers is silica.

Silica is also known as silica and has the chemical formula SIO. There are two types of silica in nature: crystalline silica and amorphous silica.

The main component of sand is silica.

Crystalline silica is divided into three types: quartz, lemostomatite and cristobalite due to different crystal structures. Pure quartz is a colorless crystal, and a large and transparent prismatic quartz is called a crystal. If the crystal containing trace impurities has different colors, there are amethyst, citrine, etc.

Ordinary sand is fine quartz crystals, with yellow sand (more iron impurities) and white sand (less impurities, purer). In the silica crystal, the 4 valence electrons of the silicon atom and the 4 oxygen atoms form 4 covalent bonds, the silicon atom is located in the center of the regular tetrahedron, and the 4 oxygen atoms are located on the 4 apex angles of the regular tetrahedron. Silica is an atomic crystal.

Silica is widely found in nature and together with other minerals make up rocks. Natural silica is called silica, which accounts for about 12% of the earth's crustal mass, and its existence is in two forms: crystalline and amorphous. Quartz crystals are crystalline silica with different crystal forms and colors.

The colorless and transparent crystals in quartz are what are commonly referred to as crystals. The ones that have colored rings, bands, or layers are called agate (which contains impurities).

Silicon dioxide. Also known as silica, the chemical formula SIO. There are two types of silica in nature: crystalline silica and amorphous silica. The manufacture of optical fibers is based on the total reflection of light by silica crystals.

It is not to use electrical conductivity.

The optical fiber is a transparent glass fiber filament, with a diameter of only about 1 100 m. It is composed of two layers, the inner core and the outer coat, and the refractive index of the inner core.

Larger than the refractive index of the coat, light enters from one end and is emitted from the other end after multiple total reflections at the interface between the inner core and the coat. Optical fibers are mixtures and are amorphous. At present, the main component of optical fibers is silica.

It is a light guide, and it has nothing to do with electricity conduction.

Silica is transparent, has a suitable refractive index, and is capable of total reflection. And the reserves are abundant, and the cost is relatively low.

It is used to create a reflection of light in the circuit.
