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

Requirements for Bending Radius

lThe 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.).

lThe 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.).

lThe bending radius of the power cable or PGND cable must be at least three times the

diameter of the cable.

lThe bending radius of a fiber optic cable is at least 20 times the diameter of the fiber optic

cable, and the minimum bending radius of the breakout cable at each end of the fiber optic

cable is 30 mm (1.18 in.).

lThe bending radius of the E1/T1 cable must be at least three times the diameter of the cable.

lThe bending radius of the signal cable must be at least five times the diameter of the cable.

Requirements for Cable Binding

lThe same types of cable must be bound together.

lDifferent types of cable must be separately routed with the minimum spacing of 30 mm

(1.18 in.) and cannot be entangled.

lThe cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.

lCable ties are installed in the same direction, and those at the same horizontal line must be

in a straight line.

lThe excess of indoor cable ties is trimmed off, and the excess of outdoor cable ties allows

about 5 mm (0.2 in.), without remaining rough edges.

lLabels or nameplates must be attached to both ends, joints, or turns of cables after they are

installed.

Security Requirements

lCables should be placed away from sharp objects or wall burrs. If these positions are

inevitable, protect the cables with protection pipes.

lCables must be routed away from heat sources, or heat-insulation materials are added

between cables and heat sources.

lSufficient slack (recommended for about 0.1 m [0.33 ft]) is provided in cables at turns or

the position close to a device, facilitating cable and device maintenance.

Indoor Cabling Requirements

lCables are routed indoors through the feeder window.

DBS3900 (ICR)

Installation Guide 15 Installing Cables

Issue 12 (2015-04-30) Huawei Proprietary and Confidential

106

lDrip loops must be made outside the feeder window, and the requirements for the minimum

bending radius are met.

lWhen cables are routed indoors, engineers are required indoors for cooperation.

lThe feeder window must be waterproofed.

Outdoor Cabling Requirements

lCables routed outdoors must be led through a pipe when they may be damaged.

lAC power cables, transmission cables, and cables buried in the ground must be protected.

lIf 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.

lIf 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.

lWhen 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.

lCables are secured with cable clips.

lCables are routed neatly along the specified cabling direction and secured with cable clips.

lThe 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.

lCable clips must be vertical with cables, and the cables in a cable clip must be parallel.

lAfter 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

lPower cables must be installed in the position specified in engineering design documents.

lIf the length of power cables is insufficient, replace the cables rather than adding connectors

or soldering joints to lengthen the cables.

lCables must be routed by only qualified and trained personnel before all preparations are

made.

lCables are routed in an untangled and orderly fashion.

lIf 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.

DBS3900 (ICR)

Installation Guide 15 Installing Cables

Issue 12 (2015-04-30) Huawei Proprietary and Confidential

109

lIf 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

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

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.

lE1 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

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.

DBS3900 (ICR)

Installation Guide 15 Installing Cables

Issue 12 (2015-04-30) Huawei Proprietary and Confidential

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.

lAn 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

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,

as shown in Figure 15-5, Figure 15-6 and Figure 15-7.

example, the FE1 port (optical transmission port) on a GTMU/GTMUb /GTMUc supports only

the transmission rate of 100 Mbit/s and therefore can only use an optical module supporting the

transmission rate of 100 Mbit/s. If the port uses an optical module supporting the transmission

rate of 1000 Mbit/s, the transmission link may be disconnected.

Procedure

Step 1 Install an optical module, as shown in Figure 15-39 and Figure 15-40.

1. Remove the dustproof cap from the corresponding FE/GE optical port on the corresponding

BBU board.
