Impact Testing Machine (Optical cable)

Optical Fiber Cable Impact Testing Machine

Model：

GCJ-1000

Overview：

HUALONG GCJ-1000 Series Optical Fiber Cable Impact Testing Machine is intended to determine the ability of optical fiber cable withstand impact.

Descriptions

Sample
The sample is a representative cable length sufficient to carry out the specified test.
Apparatus
The apparatus allows a hammer with a 25mm rounded edge to drop vertically on a cable sample fixed on a flat steel plate. The apparatus may allow a single or multiple repeated impacts to be imparted on the cable sample.
The energy of the impact is determined by the drop height and by the weight of the hammer.
Procedure
Two procedures are commonly used:
1.A repeated impact test whereby the hammer drops on the same location in the cable sample 25times.
2.The hammer is allowed to drop on 3 different locations in the cable, typically separated by 50cm from each other. The number of impacts in each location is limited.

Pass/Fail criteria
1.The fiber attenuation does not increase by more than a predetermined value, typically 0.05dB.
2.In some case, the cable passes the test if there are no fiber breaks. This requirement is usually applied when very high impact energy is used.
3.There are no breaks or cracks in the cable elements. Signs of the impact are considered normal.
