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.
■
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 least) 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.
