Optical Fiber Cable Crush Testing MachineObject
The purpose of this test is to determine the ability of an optical fiber cable to withstand compression
Sample
The sample is a representative cable length sufficient to carry out the specified test
Apparatus
The apparatus allows a sample of cable to be crushed between a flat steel base plate and a moveable 100 mm long steel plate. The edges of the moveable plate are rounded with a radius of about 5 mm.
Procedure
The cable sample is mounted between the plates so that lateral movement is prevented, and a pre-determined force is applied gradually. The maximum applied force is typically maintained for 10 minutes.
Two types of measurements may be defined
The fiber attenuation is measured at the end of the 10-minute period while the cable is still under pressure
The fiber attenuation is measured 5 minutes after pressure. This requirement is usually carried out at higher compressive loads than the previously described measurement.
