The optical fiber directly plugged into the network cable should be unplugged in a thunderstorm.

If the optical fiber goes directly to the home, all the network cables are laid indoors. At this time, we should try to use the network cable. If the outdoor lightning rod falls down, you can unplug the network cable when it thunders. However, if the network cable is close to the lightning rod downlead and parallel to the lightning rod downlead, try to unplug the network cable when it thunders.

If the network cable enters the home, it can be divided into two situations. When the network cable is laid indoors (including the corridor) after coming out of the optical fiber equipment box, it will be treated directly at home with reference to optical fiber. The network cable runs outside the building, and try to unplug the network cable when it thunders.
