The net line is about 200 meters, and there is a repeater in the middle. Can we use it?
As for lightning, cable with plastic sheath, not by lightning theory, and you can't do lightning protection treatment, but other devices (switches, power supply, host) to do grounding switch using lightning protection switch. The cable is struck by lightning, one is induced by electricity, and the two is by lightning from other devices, which can only be done by grounding.
As for outdoor, plastic sleeve must be used, otherwise the sun and rain will not change for more than two years.
Repeaters are available, but they are rare. Wiring is more than 100 meters. It should be poorly designed. The central switch can be used. The hub is useless.
