How to install the overhead Fiber Closure : one is fixed to the pole and the fiber closure is parallel to the pole such as the cap fiber closure. The other is fixed to the hanging wire, and the fiber closure is parallel to the hanging wire. Most of it is a joint box that draws optical cables at both ends.

Horizontal Overhead If the fiber closure is fixed to the suspended wire, the joint box can be easily swung at first because the flat direction of the joint box is perpendicular to the ground, so the wind is more attractive . The second is that the seal seam faces upwards and that water easily enters the joint when the seal breaks. Third, the fiber reel in the fiber enclosure is in a vertical state, the fiber connector and the spare fiber are easily separated from their original position and in an unstable state. For example, rotate the splice box 90 degrees. You can eliminate the above inconvenient factors. Please be aware that the fiber tray faces upward.

Therefore, to install overhead fiber closure, you need to consider the following points.

1. Reduce the wind and reduce the swing of the joint box.

2. Hold the gap as far as possible to avoid rain when the seal breaks.

3. Fiber optical discs in the fiber closure are placed horizontally in the face-up position so that the fiber connectors and the reserved fibers in the fiber tray are in the most stable condition. In order to avoid breakdown as much as possible.

In the case of a cap type fiber closure fixed to a pole, it does not vibrate under the action of wind. Since the cable hole and the sealing seam are facing downward, it is difficult for rainwater to enter the fiber closure. Since the fiber closure is a vertical installation, the fiber-optic disc in the fiber closure is in a vertical state, and the fiber connector and the spare fiber are easily separated from the original position and in an unstable state. This has the disadvantage that the cap type fiber closure can not be overcome, so it is necessary to fix the fiber optic connector and the spare fiber properly to the fiber ribbon and stabilize it. Otherwise, it tends to break down.

Please note that in the case of direct buried joints and pipe joints, the winding disc faces upwards. To orient the fiber optic disc face up, the orientation of the fiber optic disc should be marked on the outside of the housing of the cable connector box, in particular on the cap type fiber closure which is displayed outside the connector. Box housing, preferably permanent. Sexual signs.
