lThe 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.

lPGND 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.

lFuses or switches must not be installed on the PGND cables.

lOther devices must not be used for electrical connections of the PGND cables.

lAll 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:

lE1 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.).

lE1 cables are routed straightly and bound neatly with cable ties.

lSufficient slack is provided in E1 cables at turns.

Cabling Requirements for Fiber Optic Cables are as follows:

lFiber optic cables must be routed by at least three qualified and trained personnel before

all preparations are made.

lFiber 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.

lCables are routed in an untangled and orderly fashion.

lDo not bind fiber optic cables at turns.

lDo not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away

from sharp objects.

lWhen fiber optic cables are routed, the excess of the cables must be coiled around special

devices, such as a fiber coiler.

lWhen coiling fiber optic cables, apply even strength. Do not bend the cables with force.

lVacant optical connectors must be covered with dustproof caps.

lFiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet.

lIf 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.

lIf 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.

lIf 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:
