Product Description
These machines offer force, displacement or deformation closed loop testing. The load frames are rigid constructed, providing superior axial and lateral stiffness.
Method E1: Tensile performance
This measuring method applies to optical fiber cables which are tested at a particular tensile strength in order to examine the behavior of the attenuation and/or the fiber elongation strain as a function of the load on a cable which may occur during installation. This method is intended to be non-destructive (the tension applied shall be within the operational values).
Method E3: Crush
The purpose of this test is to determine the ability of an optical fiber cable to withstand crushing.
Tensile performance Per IEC-60794-1-2 Method E1
Object
This measuring method applies to optical fiber cables, which are tested at particular tensile strength in order to examine the behavior of the attenuation and the fiber elongation strain as a function of the load on a cable, which may occur during installation and/or operation.
Sample
The cable length under test us 150 meters, Additional cable length is needed to connect the fibers to be tester.
Apparatus
The apparatus consists of:
1. An attenuation measuring apparatus, typically an OTDR
2. A fiber elongation strain measuring apparatus based on dispersion testing equipment
3. A specially designed tensile test machine capable of tensioning 150 meters of optical cable in six legs of 25 meters each. The machine is equipped with a motor for controlled tensioning and a load cell for measuring the actual tension applied on the cable.
Procedure
The cable is wound in the machine over appropriately sized sheaves. The cable ends extend to reach the measuring instruments. A pre-determined number of fibers within the cable are concatenated by fusion splicing. Typically, two sets of fibers are used, one will serve to measure attenuation change and the other serves for elongation monitoring.
After all initial measurements and calibration are carried out, the cable is pulled at a specified rate until a pre-determined tension is applied. The cable is laid to rest under tension as per detail specifications, and then the attenuation and fiber length are measured. This process may involve several tensile levels in order to characterize the entire tensile behavior of the cable, or be carried out only at the defined maximum allowed tension level.
Pass/Fail criteria
· Under load, the fiber attenuation is not increased more than a predetermined value, typically 0.05dB over fiber length measured.
· Under load, the fiber does elongation by more than a pre-determined value over its initial length. The allowed elongation under installation load is typically 0.25%.
Crush (Compression) per IEC-60794-1-2 Method E3
Object
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
1. 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.
2. Two types of measurements may be defined.
3. The fiber attenuation is measured at the end of the 10-minute period while the cable is still under pressure/
4. The fiber attenuation is measured 5 minutes after pressure. This requirement is usually carried out at higher compressive loads than the previously described measurement.
Pass/Fail criteria
· The attenuation must not change by more than pre-determined value, typically 0.05dB.
· In all cases, the cable elements should not fracture or crack. Signs of compression are not considered as damage to the cable elements.

Overview
HUALONG GNZ-1000 Series Optical Fiber Cable Torsion Testing Machine is intended to establish the ability of a fiber optic cable to withstand mechanical twisting.
Sample
The length of the specimen under torsion should be sufficient to permit the appropriate clamping and twisting, and long enough to sustain the applied torsion. A typical value for small cables 1m, whereas larger cable samples are usually defined in terms of the cable diameter. A common length is 125 times the cable diameter. Armored cables may require a longer cable sample or a smaller number of torsion cycles.
Apparatus
The actual sample length is longer than the part under torsion to allow connecting the fibers to be tested.
The twisting apparatus consists of two cable gripping devices or clamps, one fixed and one that can rotate. The distance between the clamps is connected to suitable turning equipment. The clamps are designed to prevent crushing force on cable and to allow the cable end to exit from both sides to allow optical measurements.

| Max. distance between grips | mm | 1000 |
| Max. twisting cycles | cycles | 1-9999 |

Overview
HUALONG GWQ-1000 Series Optical Fiber Cable Repeated Bending Testing Machine is intended to establish the ability of a fiber optic cable to withstand repeated bending (cyclic flexing).
Sample
The sample is a representative cable length sufficient to carry out the specified test.
Apparatus
The apparatus allows a cable sample to be bent backwards and forwards through at an angle of 180°, the two extreme positions making an angle of 90°on both sides of vertical, while the sample is subjected to a tensile load.
The bending arm is designed to permit holding the cable securely during the entire test, without crushing the optical fibers or inducing optical loss. The bending radius is controlled by replaceable cushioning reels chosen to match the cable bending radius.
The apparatus is capable of cycling at a rate of 30 cycles per minute.
Procedure
A cable sample is secured to the bending arm while it is in an upright position. A predetermined weight is attached to the bottom of the cable sample. The motor is turned on and the arm oscillates between the two extreme positions flexing the cable. The number of flexing cycles depends on the cable design.
Pass/Fail criteria
The fiber attenuation does not increase by more than a predetermined value, typically 0.05dB.

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