    …glass is amorphous SiO2, or silica glass. (Quartz, which is present in sand, is a crystalline form of SiO2.) In amorphous SiO2 each silicon atom is bonded to four oxygen atoms, and each oxygen atom is bonded to two silicon atoms. This structure is difficult to represent in a two-dimensional…

    …fibres are made of fused silica glass. The refractive index of either the core or the cladding is modified during the manufacturing process by diluting pure silica glass with fluorine or germanium in a process known as doping. (The manufacturing process itself is described in industrial glass: Glass forming: Optical…
