Fiber optic cables have long been the backbone of global ... They placed quantum signals in the 1290-nanometer band, where scattering from high-power C-band light—used for Internet traffic ...

Fiber is also used to replace copper cable for LAN backbones. An optical fiber is constructed of a transparent core made of nearly pure silicon dioxide (SiO2), through which the light travels.
