Reusing fiber-optic cable
Note
If you are reusing fiber-optic cables, you must shorten both fiber-optic cores by the amount
of the curved lengths and reassemble the connectors. This will prevent any attenuation
losses caused by re-bent, heavily stressed portions of the fiber-optic cores.
Reference
For more information on the installation guidelines for fiber-optic cables, refer to the
SIMATIC NET PROFIBUS Network Manual
(http://support.automation.siemens.com/WW/view/en/35222591).
