Before burying the fiber optic cable, the following tests can be performed to ensure the quality and performance of the cable:
1. Fiber optic test: Use a fiber optic tester to test the fiber in the fiber optic cable to ensure that it is working properly. The test includes checking the loss, reflection and break point of the fiber.
2. Fiber optic cable testing: Use the tester to test the entire fiber optic cable to ensure that its transmission performance meets the requirements. The test includes checking the loss, attenuation, reflection and breakpoints of the fiber optic cable.
3. Tensile test: the cable is tested for tensile strength before installation to ensure that the cable can withstand the tensile strength during installation and use.
4. Bending test: bending test to ensure that the cable can withstand different angles of bending.
5. Compression test: compression test to ensure that the cable can withstand the installation and use of the pressure.
6. Temperature testing: tests are performed at different temperatures to ensure that the cable can work properly under different ambient temperatures.
These tests ensure that the fiber optic cable is of high quality and reliability during installation and use.
