Dätwyler uses the more difficult test method exclusively. onto the cable simulated here.

Torsion
During installation, the fibre optic cable must withstand torsion forces addition tension, transverse pressure and bending loads. Thus cable sample turned about its own axis and attenuation deviations documented during the test. Determining test criteria are the time and the maximum dispersal the water within the sample.

Crush resistance
The purpose this test determine the ability data cable withstand transverse pressure. damage the cable sheath may occur.Impact
The fall heavy tool, device, stone, etc. Neither fibre nor sheath materials may damaged during the test. The weight allowed fall vertically onto intermediate steel piece that transmits the force the cable sample.

Water penetration
This method checks whether all interstices the fibre optic outdoor cable are continuously filled with compound that prevents water from entering the cable
