10 Installing Cables
10.1 Cabling Requirements
Cables must be routed according to the specified cabling requirements to prevent signal
interference.
NOTE
If a cable listed below is not required, skip the routing requirements of the cable.
General Cabling Requirements
The bending radius of the cables must meet the following specifications:
The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending
radius of the 5/4'' feeder must be more than 380 mm (14.96 in.).
The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending
radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bending
radius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.).
The bending radius of the power cable or PGND cable must be at least three times the
diameter of the cable.
The bending radius of an fiber optic cable is at least 20 times the diameter of the fiber optic
cable.
The bending radius of the signal cable must be at least five times the diameter of the cable.
The cables must be bound as follows:
The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.
The cable ties must face the same direction, and those at the same horizontal line must be
in a straight line. Extra length of cable ties must be cut.
Labels or nameplates must be attached to the cables after they are installed.
The cables must be routed as follows:
Different types of cables must be installed in an untangled and orderly fashion.
Different types of cables must be routed in parallel or separated by special objects.
Special Cabling Requirements
Cabling requirements for power cables are as follows:
Multiple power cables must be bound when routed.
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.
Cabling Requirements for PGND Cables are as follows:
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.

Installation Guide
10 Installing Cables
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 are as follows:
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.
Cabling Requirements for Fiber Optic Cables are as follows:
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.
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.
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.
If fiber optic 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.
If fiber optic 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.
If the fiber optic cables close to a device are too long, coil the excess of the cables and
secure them on the tower.
10.2 Cable Connections
The cable connections of the BTS3902E vary depending on the number of BTS3902Es and the
BTS3902E port.
The cable connections are similar when the BTS3902E uses AC power supply (working at the
1.9 GHz, 2.1 GHz or 850 MHz frequency band) or uses DC power supply (working at the AWS
frequency band). The differences are as follows:
