The fastening method of the horizontal Fiber Closure is specifically divided into stainless steel screw fastening and plug-type fastening. The cap type fiber closure adopts a hoop fastening box body, and the hoop structure has two screws fixing structure and a single the surface screw fixing structure and the quick holding structure select the corresponding type of horizontal fiber closure according to the number of incoming and outgoing optical cables. Since the cable inlet and outlet are distributed on both sides of the box body, the number of inlet and outlet cables is generally described as several in and out; and the cap type fiber closure since the inlet and outlet of the optical cable are distributed on one side of the casing, the number of inlet and outlet cables is generally described as several inlet and outlet cables; and since the inlet and outlet of the fiber closure can be sealed by plugging or plugging, the number of inlet and outlet of the product during selection is selected. It can be larger than the number of incoming and outgoing cable ports actually used.
According to the type and capacity of the optical cable, the corresponding specifications are selected: the optical cable is generally divided into two types according to the structure of the core, and the corresponding product is selected when selecting the fiber closure, and the horizontal fiber closure is not the same. The maximum capacity of the box can be used to meet the required capacity. When selecting the capacity of the fiber closure, it is necessary to select according to the structure of the cable. In the continuous working state of the monitoring equipment, the change of the power supply is normal. If the equipment requires a narrow input range, it is inevitable that the equipment will not work when the power supply changes, or even cause damage to the telephone cable distribution box, especially as the front-end equipment. The transmitter is usually installed in an outdoor equipment box. The site environment is relatively bad, and lightning protection is extremely important. The quality of the lightning protection measures directly determines the probability of failure of the cable distribution box. Configure the M-type horizontal fiber closure. The installation accessories are: sealing tape, overhead hook or wall fixing (select one of them), emery cloth, grounding wire, nylon cable ties, number paper, desiccant.
