Cabling requirements for PGND cables are as follows:

lPGND cables for the base station must be connected to the same ground bar.

lPGND cables must be buried in the ground or routed indoors. They should not be routed

overhead before they are led into the equipment room.

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 optical fibers are as follows:

lDo not stretch, step on, or place heavy objects on optical fibers. Keep the fibers away from

sharp objects.

lWhen optical fibers are routed, the extra length of the fibers must be coiled around special

devices, such as a fiber coiler.

lWhen coiling optical fibers, apply even strength. Do not bend the fibers with force.
