Asked in Electromagnetic Radiation
What form of radiation is used inside optical fibers?
Light is, but not necessarily the visible kind. For glass fibers, we use light in the infrared region, which has wavelengths longer than visible light, typically around 850, 1300 and 1550 nm. Those are used because the attenuation of the fiber is much less at those wavelengths. The attenuation of glass optical fiber is caused by two factors, absorption and scattering. Absorption occurs in several specific wavelengths called water bands due to the absorption by minute amounts of water vapor in the glass. Plastic optical fiber is made from materials that have lower absorption at shorter wavelengths, so red light at 650 nm is often used with plastic fiber.
