Before a glass fiber 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 fiber is termed as preparing of the fiber Stripping means the removal of the protective plastic cladding of the fiber This is done by so called Miller pliers. Cleaving means the defined breaking of the fiber 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 fiber by means of a ceramic or diamond blade when it is bent and exposed to a defined force in direction of the fiber axis. For this process a variety of tools are available. In a next step the fiber is supplied with a connector. For a particular fiber the right connector must be chosen. The ready cut fiber 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 fiber is bonded to the ceramic ferrule of the connector. The protruding fiber is scratched and removed. The connector is now ground and polished. By means of a fiber inspection microscope the connector is inspected if the face of the fiber has the desired optical quality.
In this workshop the hand grinding and polishing of optical fiber is introduced and trained. This method is useful in research labs or other places with occasional requirements.

The stripped fiber is inserted into the ferrule of the connector The stripped fiber is inserted into the ferrule of the connector which is filled with an epoxy adhesive.
The protruding fiber is scribed with the scriber with a hard tungsten blade and broken apart After hardening of the adhesive, the protruding fiber is scribed with the scriber with a hard tungsten blade and broken apart.
The first polishing step is performed as 'air polish' The first polishing step is performed as "air polish". This removes irregular broken parts avoiding chipping by the latter polishing.
Subsequently to the air polishing the final poslihing takes place Subsequently to the air polishing the final poslihing takes place.
Scribing the fiber   Placeholder image From time to time the polished surface of the fiber connector is checked with the handheld microscope. If you see an image as shown on the left, the fibre is perfect.
