AC power cables, transmission cables, and cables buried in the ground must be protected.
If cables at the cabinet bottom need to be routed through a pipe along the ground, lead the
pipe into the cabinet base for about 30 mm (1.18 in.) to 50 mm (1.97 in.), not into the
cabinet. Block the pipe with waterproof tape or silicon gel, and secure the pipe to the cable
hole at the cabinet bottom with metal piece.
If cables at the cabinet bottom need to be routed through a pipe along the metal cable trough,
do not lead the pipe into the cabinet base. The cable trough must be sealed and routed
through the cable hole at the cabinet bottom.
When routing RRU cables, ensure that the highest positions of the routes of all RRU cables
(except RF cables and AISG cables) must be lower than the bottom of the RRU.
Cables are secured with cable clips.
Cables are routed neatly along the specified cabling direction and secured with cable clips.
The positions for cable clips are determined onsite. For example, the cable clips for the
7/8" feeder are installed at the spacing of 1.5 m (4.92 ft) to 2 m (6.56 ft) in the same direction,
and the cable clips for the power cables are installed at the spacing of 1.5 m (4.92 ft) to 2
m (6.56 ft) in the same direction.
Cable clips must be vertical with cables, and the cables in a cable clip must be parallel.
After routing cables neatly and correctly, tighten the screws on cable clips.
Secure cables on the cable tray, as shown in Figure 15-1.

Special Cabling Requirements
Cabling Requirements for Power Cables
Power cables must be installed in the position specified in engineering design documents.
If the length of power cables is insufficient, replace the cables rather than adding connectors
or soldering joints to lengthen the cables.
Cables must be routed by only qualified and trained personnel before all preparations are
made.
Cables are routed in an untangled and orderly fashion.
If DC power cables need to be routed on the tower platform, lay out the cables on the
guardrail with the shortest distance and route the cables along the guardrail.

15 Installing Cables
If DC power cables need to be routed close to a device on the tower, secure the cables to
the guardrail or pole with cable clips. The device cannot be far away from the position for
securing the cables.
Cabling Requirements for PGND Cables
PGND cables for the base station must be connected to the same ground bar.
PGND cables must be buried in the ground or routed indoors. They should not be routed
overhead before they are led into the equipment room.
The exterior of the coaxial wire and the shield layer of the shielded cable must have proper
electrical contact with the metal surface of the equipment to which they are connected.
PGND cables and signal cables must be installed in an untangled and orderly fashion. A
certain distance must be reserved between them to prevent interference from each other.
Fuses or switches must not be installed on the PGND cables.
Other devices must not be used for electrical connections of the PGND cables.
All the metal parts in the housing of the equipment must be reliably connected to the ground
terminal.
Cabling Requirements for E1 Cables
E1 cables must not cross power cables, PGND cables, or RF cables when routed. If
transmission cables are routed with power cables, PGND cables, or RF cables in parallel,
the spacing between them must be greater than 30 mm (1.18 in.).
E1 cables are routed straightly and bound neatly with cable ties.
Sufficient slack is provided in E1 cables at turns.
E1 cables cannot be squeezed by the cabinet door when routed through the cabinet, as
shown in Figure 15-3.
Figure 15-3 E1 cables routed through the cabinet
Cabling Requirements for Fiber Optic Cables
Fiber optic cables must be routed by at least three qualified and trained personnel before
all preparations are made.
Fiber optic cables are used within the temperature range of -40°C to 60°C. If the current
temperature is out of the range, make protection measures or route the cables again.

15 Installing Cables
Cables are routed in an untangled and orderly fashion.
Do not bind fiber optic cables at turns.
Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away
from sharp objects.
When fiber optic cables are routed, the excess of the cables must be coiled around special
devices, such as a fiber coiler.
An unarmored fiber optic cable must be bound using binding straps. If a fiber optic patch
cord needs to be secured in a cabinet or a piece of equipment, use binding straps to bind it
and then use cable ties to secure the binding straps to the cabinet or equipment. Ensure that
the fiber optic cables can flexibly move in the cable ties. Do not bend the fiber optic cables
sharply. The following figure shows how to bind the fiber optic cables correctly.
Figure 15-4 Binding fiber optic cables
When coiling fiber optic cables, apply even strength. Do not bend the cables with force.
Vacant optical connectors must be covered with dustproof caps.
Fiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet,
as shown in Figure 15-5, Figure 15-6 and Figure 15-7.
