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.

Requirements for Cabling Indoors

■

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.

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.
