Unformatted text preview: ibre-optic cables predominantly in the infrared range. Glass fibre-optic cables absorb considerably less light in this wavelength range than polymer fibre-optic cables. In contrast, polymer fibre-optic cables are particularly flexible and can be cut to a required length. 196 © Festo Didactic GmbH & Co. KG • FP 1110 11.
