Optical fiber distribution box is a connection equipment used in optical cable connection in the communication industry. During installation, it is open air and cannot be prevented from being damaged. Therefore, its maintenance must be done well. Only by doing a good job of maintenance can the occurrence of faults be successfully reduced. Next,China Fiber Optic Splice Closure Manufacturers will give you a specific introduction on how to do a good job in this aspect of maintenance.

Due to the outdoor setting, the optical fiber distribution box will lead to water ingress, insolation and slow aging. It is conceivable that this will directly affect its service life. Moreover, the waterproof performance of this product is very poor, and the impact is due to the weather. Once the optical fiber distribution box enters the water, it will cause short circuit, which is easy to cause large-scale power failure. Every time after the rain, most of the optical fiber distribution boxes will be burnt out, which will greatly increase the maintenance workload of the device. The reason why this product is easy to enter water is that the space in the box is small. The power supply inlet of 35 square millimeter cable is fixed with plastic expansion pipe, thus there is no room for waterproof bending, resulting in rainwater flowing to the live terminal along the cable. As the gap of the terminal is small, the insulation measures are not in place, and it is easy to short circuit after entering water. In addition to this product's own design defects, there are radiating holes and wiring holes around it, which become water inlet holes when it rains.

In addition, maintenance personnel should also inspect and maintain the low-voltage Optical Fiber Distribution Box in use as scheduled, re-crimp the wires in the box in time, re-process the insulation strength, replace the damaged wires or wires with insufficient insulation and serious aging in time, and install optical cable splice boxes when necessary to prevent excessive wiring.
