Abstract
A method of coating an oblong shaped body () made of polymer material, which is intended for guiding light in the form of optical signals. In this case, a coating made of polymer material having a lower index of refraction than the shaped body () is applied around the shaped body (). To generate the coating, a coating facility (A) having at least one chamber () is used, to which a halogenated gas () and/or gas mixture is supplied. The halogenated gas () and/or gas mixture is converted into a plasma () in the chamber () under the effect of microwaves () and conducted out of the chamber () through a nozzle (). The shaped body () is moved at least one time over its entire length along the coating facility (A) in the region of the nozzle () and/or the plasma () emitting therefrom and, at the same time, provided with a coating () made of a halogenated polymer, which is generated by the incidence of the plasma ().
