When choosing the right cabinet, the user will carefully select the right cabinet, but don't forget that when you select the right cabinet, you should also pay attention to the location of the cabinet installed. For example, due to the advantages of fiber optic cable, such as bandwidth, electromagnetic insulation, small attenuation and large distance between repeaters, it is widely used as transmission medium in LAN backbone at present. However, after the fiber optic cable is introduced into the room, it needs to be installed with extra caution. The difficulty of tapping is its inherent problem. When connecting each fiber optic cable, polishing must be done. The end is connected with the optical interface by electric barbecue or chemical chlorine process to ensure that the optical channel is not blocked.　　

Fiber optics are brittle in texture, easy to break, can not be pulled too tight, nor can they form right angles. Then the cabinet with the optical fiber cooker should be installed in a place convenient for maintenance and relatively fixed position. If there is no special need, the position of the network cabinet will not be adjusted. The installation space of the cabinet should be planned before installation. In order to facilitate heat dissipation and equipment maintenance, it is suggested that the distance between the front and back of the cabinet and the wall or other equipment should not be less than 0.8 meters, and the net height of the computer room should not be less than 2.5 meters.
