Note
In certain sections, if the Ethernet cable is parallel with the
power cable or near interference sources such as
electromotor and transformer, and the minimum net spacing
between them cannot address requirements, you can use
steel tube or metal trough to shield the Ethernet cable.

Because outdoor overhead cabling is easy to couple up lightning and damage equipments, it is forbidden to use
the outdoor overhead Ethernet cabling, especially use the following cabling methods directly without any
protection measures.
