12.4 Installation of 󹪝ber-optic cables
Introduction
Fiber-optic cables may only be installed by trained and quali󹪝ed 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 󹪝ber-optic cable due to an insu󹪟cient 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 󹪝ber-optic cables:
• Does the delivered package contain the correct 󹪝ber-optic cables?
• Any visible transport damage to the product?
