Publish Time: 2025-04-14
Indoor branch optical cable, such as GJPFJV optical cable, undertakes important signal transmission tasks in complex and changeable indoor environment. In order to ensure its stability and reliability under various working conditions, the tensile and compressive performance tests are particularly important. These tests are not only related to the physical strength of the optical cable, but also directly affect its durability and safety in practical applications.For the tensile performance of indoor branch optical cable, the test method usually simulates the tensile force that the optical cable may encounter during the wiring process. This includes gravity stretching during vertical wiring and friction stretching during pipe laying. During the test, the optical cable is fixed at both ends of the test equipment, and the tensile force is gradually applied until it reaches or exceeds the tensile strength limit of the optical cable design. The tensile performance of the optical cable can be evaluated by observing the deformation and breakage of the optical cable during the stretching process, and measuring the relationship between the tension and elongation. For GJPFJV optical cable, the structural design of its tight-buffered optical fiber and multi-core bundled optical cable, as well as the reinforcing effect of the FRP stranded layer, should be verified in the tensile test.The test of compressive performance focuses on the ability of the optical cable to withstand compression or pressure. In indoor environments, optical cables may be subjected to pressure due to furniture placement, people stepping on them, etc. The compression test usually uses special pressure testing equipment to apply uniform or local pressure to the optical cable, observe its deformation, and measure the relationship between pressure and deformation. For GJPFJV optical cable, its PVC or LSZH sheath and the dry water-blocking material between the cable core and the sheath should show good protection performance in the compression test to ensure that the optical fiber inside the cable is not damaged.When conducting tensile and compressive tests, the actual use environment of the optical cable must also be considered. For example, environmental factors such as temperature and humidity may affect the performance of the optical cable. Therefore, the test should be carried out in a laboratory that simulates actual environmental conditions to ensure the accuracy and reliability of the test results.In addition, during the test, attention should be paid to the protection of the optical cable to avoid damage to the optical cable due to excessive stretching or compression. After the test, the optical cable should be fully inspected to assess its damage and record the test data for subsequent analysis.For indoor branch optical cable, the test of tensile and compressive properties is an important part of ensuring its quality and safety. Through scientific testing methods and strict testing standards, optical cable products with excellent performance can be screened out to provide stable and reliable protection for indoor signal transmission. At the same time, the problems found during the test can also provide valuable reference for the design and optimization of optical cables.
