Cabling Reasonably

In the actual network environment, you may need cable outdoors and indoors, and
the requirements for cabling outdoors and indoors are different. A reasonable cabling
system can decrease the damage of induced lightning to devices.
Note: It's not recommended using Ethernet cables outdoors. When cabling outdoors,
please use a signal lightning arrester.

When cabling indoors, keep a certain distance away from the devices that may cause
high-frequency interferences, such as down-conductor cable, powerline, power
transformer and electromotor.

Requirements for Cabling Outdoors
Aerial cabling without safeguard is not allowed.
It's not allowed cabling down the building to connect network devices in different
floors.
Outdoor cables should be buried and paved to the indoor through basement. A piece
of steel wire should be paved underground along the pipe and connected to the
lightning protection terminal of the building for shielding. Before connecting the cable
to the device, install a signal lightning arrester on the corresponding port.
When an aerial cable is set up, the cable should be through a metal pipe (15m long
at least1 before coming into the building. The two ends of this metal pipe should be
grounded. Before connecting the cable to the device, install a signal lightning arrester
on the corresponding port.
It's not necessary to pave STP cables through pipes. The shielded layer of STP cable
should be well grounded. Before connecting the cable to the device, install a signal
lightning arrester on the corresponding port.
Requirements for Cabling Indoors
The main cable should be paved in the metal raceway of the access shaft. When
cabling, keep the loop area formed by the cable itself as small as possible.
