How to Fix the Fiber Closure

Installation method of overhead Fiber Closure : one is fixed on the pole, the fiber closure is parallel to the pole, such as the cap fiber closure; the other is fixed on the hanging wire, and the fiber closure is parallel to the hanging wire Most of them are joint boxes that lead out the optical cable at both ends. When the horizontal overhead fiber closure is fixed on the hanging wire, the first is because the flat direction of the joint box is perpendicular to the ground, so the wind is more attractive, the joint box is easy to swing; the second is that the sealing seam is facing upward, when the seal fails, the water easily enters the joint. The third is that the fiber reel in the fiber closure is in a vertical state, and the fiber connector and the reserved fiber are easily separated from the original position and are in an unstable state. For example, rotate the splice box 90 degrees. You can eliminate the above unfavorable factors, just pay attention to the fiber tray facing up. Therefore, the installation of the overhead fiber closure must consider the following points: 1. Reduce windage and reduce the swing of the joint box; 2. Seal the gap as far as possible or toward the side to prevent rain from entering when the seal fails; 3. The fiber-optic disk in the fiber closure is placed in a horizontal and face-up position, so that the fiber connector and the reserved fiber in the fiber tray are in the most stable state. In order to avoid failure as much as possible. For the cap type fiber closure fixed on the pole, it will not oscillate under the action of the wind. Since the cable hole and the sealing seam are facing downward, the rainwater does not easily enter the fiber closure; but the fiber closure is vertical Installation, the fiber-optic disk in the fiber closure is in a vertical state, and the fiber connector and the reserved fiber are easily separated from the original position and are in an unstable state. This is a disadvantage that the cap type fiber closure cannot overcome, so it is necessary to properly fix the fiber optic connector and the reserved fiber in the fiber reel to make it in a stable state, otherwise it is prone to failure. For direct-buried joints and pipe joints, just pay attention to the winding disk facing up. In order to make the fiber-optic disk face up, the orientation of the fiber-optic disk should be marked on the outside of the housing of the cable connector box, especially the cap-type fiber closure, which should be represented outside the connector box housing, preferably permanent.
