Abstract
The invention relates to a proof testing method and a proof testing apparatus for optical fibre where a fibre () is guided to a first pulling device () and further to a second pulling device () and then onto a reel (), whereby the pulling devices subject the fibre to a desired amount of tensile strength, as a result of which the fibre breaks if the fibre () strength is insufficient. To achieve a continuous pulling and proof testing process, the fibre end is guided in the case of a fibre break between the first and the second pulling device () by means of a first channel section (), which guides the fibre to the second pulling device (). After the second pulling device () the fibre end is guided into a second channel section () which is off the normal fibre track and along which the fibre () is guided into a scrap fibre processing system. At a desired moment the fibre () is guided from the second channel section () to the normal track, along which the fibre is guided onto a reel ().
