Use Seals, Never Pull The Seal To Avoid Leakage
Feb 07, 2018

After the optical fiber connector is protected by the connector box, it should be protected from the moisture and should not increase the attenuation of the optical fiber connector before protection and meet the following requirements:

Optical performance

The remaining optical fiber in the optical fiber cable splice box is wound in the optical fiber installation device. In the operation of installing and using the optical cable splice box, the optical fiber connector should have no obvious additional attenuation.

Sealing performance

After the optical fiber cable connector box is packaged according to the stipulated operating procedures, the inflation pressure in the optical cable connector box should be (100 ± 5) kPa, soak in the clear water container at room temperature for 15 minutes and observe that there should be no bubbles to escape or observe the 24-hour barometer Indication should be unchanged.

Re-seal performance

Cable connector box according to the provisions of the operating procedures repeated three times after the test package. Inflatable cable connector box pressure l00kPat5kPa, soaked in water containers at room temperature for 15 minutes should be observed stable observation of bubbles escape, or stable observation of 24-hour barometer indicating no change.

Mechanical behavior

After the following tests, the cable splice box body and the box should not change the various parts, if necessary, through the light or open the box to check. The following tests should be filled in the cable splice box (60 ± 5) kPa barometric pressure after the test should be no change; immersed in water containers at room temperature for 15 minutes of steady observation should be no bubbles to escape or stable observation 24h barometer indicators There should be no change, the shell and its components should be no cracks, damage and significant deformation.

Box sealed

1, the box body package: before the box body valve seal and grounding screw and tight. • Insert the sealing strip into the sealing groove around the box body. • Insert the sealing strip into the groove at the "U" groove at both ends of the joint box. Note: Use the sealing strip, do not pull the sealing strip manually to avoid leakage.

2. Close the upper cover of the connector box gently and screw in the fastening bolt. Tighten the bolts in the order of the numbers indicated on the cover and tighten them with torque wrench. The torque reaches 25N · m.

3, to be 5 minutes later, then tighten torque torque wrench, torque still reached 25N · m.
