Installation of fiber-optic cables

Introduction
Fiber-optic cables may only be installed by trained and qualified personnel. Always observe the
applicable rules and statutory regulations. The installation must be carried out with meticulous
care, because faulty installations represent the most common source of error. Causes are:
• Kinking of the fiber-optic cable due to an insufficient bending radius.
• Crushing of the cable as a result of excess forces caused by persons treading on the cable, or
by pinching, or by the load of other heavy cables.
• Overstretching due to high tensile forces.
• Damage on sharp edges etc.
Local quality assurance
Check the points outlined below before you install the fiber-optic cables:
• Does the delivered package contain the correct fiber-optic cables?
• Any visible transport damage to the product?
