Installing fiber-optic cables
Introduction
Fiber-optic cables may only be laid by trained specialist personnel. Comply with all
applicable regulations and statutory requirements.
In practice, the installation of fiber-optic cables represents the most common cause of errors
and failures. These can be caused by:
●
Kinks in the fiber-optic cable due to an insufficient bending radius
●
Crushing as a result of excessive force caused by persons treading on the cable, by
pinching, or by other heavy cables
●
Overstretching due to high tensile forces
●
Damage caused by sharp edges
Quality assurance on site
Check the following points before laying the fiber-optic cables:
●
Has the correct fiber-optic cable been delivered?
●
Is there any visible transport damage to the product?
●
Have you organized suitable intermediate on-site storage for the fiber-optic cables?
●
Does the category of cable match that of the connecting components?
Storage of fiber-optic cables
Store fiber-optic cables in a place where they are protected from mechanical and thermal
factors.
Observe the permitted storage temperatures. These are specified in the data sheet for the
fiber-optic cable. If possible, do not remove fiber-optic cables from their original packaging
until you are about to install them.
Permitted bending radii for pre-assembled cables
You may not go below the following bending radii when laying the fiber-optic cables:
●
Next to connector: 55 mm
●
During installation: 60 mm (repeatedly)
●
After installation: 40 mm (once)
