Thus cable sample turned about its own axis and attenuation deviations documented during the test. After that, the electrical and parameters must still correspond the 50173 standard. onto the cable simulated here.

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.Impact
The fall heavy tool, device, stone, etc. Determining test criteria are the time and the maximum dispersal the water within the sample. The weight allowed fall vertically onto intermediate steel piece that transmits the force the cable sample. Neither fibre nor sheath materials may damaged during the test.

Crush resistance
The purpose this test determine the ability data cable withstand transverse pressure. Dätwyler uses the more difficult test method exclusively.

Torsion
During installation, the fibre optic cable must withstand torsion forces addition tension, transverse pressure and bending loads. damage the cable sheath may occur
