Problems solved by technology

It will directly affect the use of the optical cable. If the wear resistance of the optical cable does not meet the requirements, the sheath of the optical cable will be broken due to mutual friction during the installation and use of the optical cable, and the internal structure of the optical cable cannot be well protected or fixed. The structural stability of the optical cable is destroyed, resulting in unstable transmission performance of the optical cable; at this time, when the optical cable is subjected to external force, due to the damage of the sheath of the optical cable, it may directly lead to the fracture and failure of the optical cable inside the optical cable.
At present, although there are methods and equipment for testing the wear resistance of optical cables in China, this test is only suitable for the use of ordinary optical cables. The grinding frequency can reach 10 cycles / s, which cannot be met by domestic test methods and test equipment

Embodiment 1

[0025] A single-core optical cable with a sheath with a nominal diameter of 1.8mm requires an abrasion resistance cycle of 1,000,000 times between optical cables, a speed of 10 times / second, and a hanging weight of 1.0kg.

[0026] like figure 1 The equipment shown is tested by first attaching a section of fiber optic cable to the figure 2 Use the two lower clamps to fix it, and then fix one end of the other optical cable with the upper clamp, connect the other end with a 1.0kg weight, wrap around the lower fixed optical cable and place it on the fixed pulley. The placed optical cable sample should be and figure 2 unanimous.

[0027] The equipment starts, enters the operation screen 10 of the man-machine interface, and the state of the motor of the private server is set to run. Enter the parameter setting, set the speed to 10 times per second, set the disconnection function to non-stop when disconnected, set the number of actions to 1,000,000 times, return to the display i...

Embodiment 2

[0029] A kind of secondary buffer layer 62.5 / 125μm multimode optical fiber cable, the diameter of the optical cable is 0.9mm, the abrasion resistance cycle between optical cables is required to be 10000 times, the speed is 10 times / second, the hanging weight is 2.2N, and it is fixed around the bottom Place the optical cable on the fixed pulley after one lap, and the placed optical cable sample should be the same as figure 2 unanimous.

[0030] like figure 1 The equipment shown is tested by first attaching a section of fiber optic cable to the figure 2Use the two lower clamps to fix it, and then fix one end of the other optical cable with the upper clamp, and connect the other end to a 2.2N weight, and place it on the fixed pulley after wrapping around the lower fixed optical cable. The placed optical cable sample should be and figure 2 unanimous.

[0031] The equipment starts, enters the operation screen 10 of the man-machine interface, and the state of the motor of the...

Description

technical field [0001] The invention relates to the testing technology of optical cables, in particular to a method and equipment for testing the abrasion resistance between optical cables. Background technique [0002] The processing purpose of the optical cable is to protect the optical fiber inside, so that the optical fiber can be used normally under certain environmental conditions or mechanical stress. The performance test of optical cable is very important to the quality of optical cable products. It will directly affect the use of the optical cable. If the wear resistance of the optical cable does not meet the requirements, the sheath of the optical cable will be broken due to mutual friction during the installation and use of the optical cable, and the internal structure of the optical cable cannot be well protected or fixed. The structural stability of the optical cable is destroyed, resulting in unstable transmission performance of the optical cable; at this time...
