How it works ...
Before a glass fibre can be used in real application outside the laboratories, it has to be fixed to a connector. The entire process of stripping, cleaving, cementing and polishing the entrance window of the fixed fibre is termed as preparing of the fibre. Stripping means the removal of the protective plastic cladding of the fibre. This is done by so called Miller pliers. Cleaving means the defined breaking of the fibre in such a way that the face of it is perpendicular and of optical quality after the process. This can be achieved by slightly scratching the fibre by means of a ceramic or diamond blade when it is bent and exposed to a defined force in direction of the fibre axis. For this process a variety of tools are available. In a next step the fibre is supplied with a connector. For a particular fibre the right connector must be chosen. The ready cut fibre is dipped in one component of a two compound glue and inserted into the ferrule of the connector which already is filled with the second compound of the glue. After a while the fibre is bonded to the ceramic ferrule of the connector. The protruding fibre is scratched and removed. The connector is now ground and polished. By means of a fibre inspection microscope the connector is inspected if the face of the fibre has the desired optical quality.
In this workshop the hand grinding and polishing of optical fibre is introduced and trained. This method is useful in research labs or other places with occasional requirements.
