1.3.2 Laying of optical fiber cables (part three)

Mechanical load of optical fiber cable

Observe the following instructions:

1. Do not twist the optical fiber cable!
   
   
   
   
2. Do not pinch the optical fiber cable.
   
   
   

3. Observe the permissible tensile forces. Do not overstretch the optical fiber cable.
   
   
   

Use pulling supports, protect connectors

1. Use suitable pulling supports for pulling in optical fiber cables. Some manufacturers supply the correct pulling support with the optical fiber cable. If no pulling support is supplied, ask the cable manufacturer for the appropriate pulling support.
   
   
   
   
2. Protect pre-assembled plug connections against damage and dirt. A cable conduit can be used for this purpose. Pad any cavities.
   
   
   
   
3. Ensure that the dust-protection caps are fitted.

Attaching the strain relief

1. Some plug connections for optical fiber cables feature their own strain relief. Nevertheless, attach an additional strain  relief as close as possible to the PROFIBUS station.
