7.12.1 Preparation of Optical Fiber Cables with
Connector
Every optical fiber connector requires an optical fiber cable with a male connector. The
following information applies for connectors used in applications with 1 mm standard
plastic optical fibers (POF).

Technical data Rated value
Storage temperature -40 to 70 °C
Operating temperature -20 to 70 °C
Between optical fiber cable and connector 19.6 NTensile stress
Optical fiber cable 49 N
Bending radius
When bending the optical fiber cable to install it, note that the recom-
mended bending radius is 6 to 10 times greater than the minimum bend-
ing radius.
Min. 25 mm
Procedure
1. Remove at least 7 mm of the optical fiber cable's plastic sheat (diameter 2.2 mm);
see figure, [1]). Take care that the dismantled end of the optical fiber cable is not
contaminated. If necessary, clean it gently with a dry tissue paper.
2. Insert the dismantled optical fiber cable carefully as shown in the figure into the con-
nector. The polymer fiber of 1 mm should stand out from the connector about 1 to
2 mm (see figure, [2]).
3. Press the clip of connector so that the polymer fiber is hold in the connector. The
connector and the clip must interlock audibly (see figure, [3]).
4. Insert the connector with the optical fiber cable into a polishing disk and grind the
outstanding end of the fiber by means of a polishing sheet on an even surface (e.g.
glass sheet), see figure, [4]). Remove grinding residues.
