Do you know the performance requirements of the cable splice box
After the fiber connector is protected by the connector box, it should be protected from moisture, and the attenuation of the fiber connector before protection should not be increased, and it should meet the following requirements:
Optical performance
The remaining optical fiber in the optical cable connector box is coiled in the optical fiber placement device. During the installation and use operation of the optical cable connector box, the optical fiber connector should have no obvious additional attenuation.
Sealing performance
After the optical cable connector box is packaged according to the specified operating procedures, the air pressure in the optical cable connector box is (100±5) kPa, soak in a clean water container at room temperature for stable observation for 15 minutes, and no bubbles should escape, or observe the barometer for 24 hours. The instructions should remain unchanged.
Resealability
The optical cable connector box is tested after being encapsulated three times in accordance with the prescribed operating procedures. The inflation pressure in the optical cable connector box is l00kPa±5kPa, and it should be immersed in a clean water container at room temperature for stable observation for 15 minutes, and no bubbles should escape, or stable observation for 24 hours, the barometer indication should be unchanged.
Mechanical behavior
After the following tests, there should be no change in the box body of the optical cable connector box and various parts in the box. If necessary, perform a light inspection or open the box body to check. The following tests should be filled with (60±5) kPa air pressure in the optical cable connector box, and the air pressure should not change after the test; it should be observed stably for 15 minutes in a clean water container immersed at room temperature, and no air bubbles should escape or stable observation 24h barometer indicators There should be no change, and the shell and its components should be free of cracks, damage and obvious deformation
