Abstract: A method of coating an oblong shaped body (8) 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 (8) is applied around the shaped body (8). To generate the coating, a coating facility (A) having at least one chamber (1) is used, to which a halogenated gas (4) and/or gas mixture is supplied. The halogenated gas (4) and/or gas mixture is converted into a plasma (6) in the chamber (1) under the effect of microwaves (5) and conducted out of the chamber (1) through a nozzle (7). The shaped body (8) is moved at least one time over its entire length along the coating facility (A) in the region of the nozzle (7) and/or the plasma (6) emitting therefrom and, at the same time, provided with a coating (9) made of a halogenated polymer, which is generated by the incidence of the plasma (6).
