l
PGND cables for a base station are connected to the same ground bar.
l
PGND cables are buried in the ground or routed indoors. They cannot be routed overhead
before they are routed into the equipment room.
l
Outer conductors of coaxial cables and both ends of the shield layers on shielded cables
are in proper electrical contact with the metal surface of the equipment to which they are
connected.
l
PGND cables and signal cables are installed in an untangled and orderly fashion. A certain
distance is reserved between them to prevent interference from each other.
l
Fuses or switches are not allowed on PGND cables.
l
Other devices cannot be used for electrical connections of PGND cables.
l
All the metal parts in the equipment are reliably connected to the ground terminal.
Optical cable
l
A minimum of three qualified or trained personnel are required to route optical cables.
l
The ambient temperature for optical cables ranges from -40°C to +60°C. If the actual
temperature is not within the range, preventive measures are taken or a new cabling route
is required.
l
Cables are routed in an untangled and orderly fashion.
l
Optical fibers cannot be bound at turns.
l
Optical fibers cannot be stretched with too much force or stepped on, and they are far away
from sharp objects. Heavy objects cannot be placed on optical cables.
l
When optical cables are routed, the extra length of the cables is coiled around special
devices, such as a fiber coiler.
l
Even strength is applied when optical cables are coiled and optical cables cannot be bent
in a forcible manner.
l
Vacant optical connectors are covered with dust-proof caps.
l
If optical cables need to be routed on the tower platform, the optical cables are routed along
the inner side of the guard rail and the distance between the guard rail and the cable is the
shortest one.
l
If optical cables need to be routed close to a device on the tower, the optical cables are
secured to the guard rail or pole with cable clips and the device cannot be far away from
the position for securing the optical cables.
l
If the optical cable close to a device on the tower is too long, the optical cables are wrapped
and secured to the tower.
