After the optical fiber connector is protected by the closure, it should be protected from moisture, should not increase the attenuation of the fiber connector prior to protection, and meet the following requirements:
The remaining optical fiber in the optical fiber cable splice case is coiled in the optical fiber placement device. In the operation of installing and using the optical cable splice box, and there should have no significant additional attenuation in the optical fiber connector.
After the cable connector box is sealed according to the specified operating procedures, the pressure in the cable connector box is (100 ± 5) kPa. Soak in a clean water container at room temperature for 15 minutes to observe no bubbles, or observe the 24-hour barometer which instructions should not change.
The optical cable splice box is tested 3 times by repeating the package according to the specified operating procedure. The inflation pressure in the cable joint box is l00kPat5kPa, soaked in a clear water container at normal temperature for 15 minutes, and there is no air bubbles escape, or the stable observation for 24 hours indicating that the barometer should not change.
After the following tests, there should be no change in the cable box box and all parts of the box. If necessary, check the light or open the box. The following tests should be filled (60 ± 5) kPa pressure in the cable connector box, the pressure should not change after the test;, stable observation of 15 minutes with immersed in water at room temperature and there should be no air bubbles escape or stable observation 24h barometer index. There should be no change, and the shell and its components should be free of cracks, damage and significant deformation.
