This section describes the procedures for installing eAN3810A cables and auxiliary devices

cables.

1.9.1 Cabling Requirements

Cables must be laid out according to the specified cabling requirements to prevent signal

interference.

If a cable listed below is not required, skip the cabling requirements of the cable.

General Cabling Requirements

Bending radius requirements

 The bending radius of a 7/8'' feeder must be greater than 250 mm (9.84 in.), and the

bending radius of a 5/4'' feeder must be greater than 380 mm (14.96 in.).

 The bending radius of a 1/4'' jumper must be greater than 35 mm (1.38 in.). The bending

radius of a super-flexible 1/2'' jumper must be greater than 50 mm (1.97 in.), and the

bending radius of an ordinary 1/2'' jumper must be greater than 127 mm (5.00 in.).

 The bending radius of a PGND cable must be at least three times its diameter.

 The bending radius of a signal cable must be at least five times its diameter.

Cable binding requirements

 Cables of the same type must be bound together.

 Different types of cables must be separately laid out and bound, with a minimum

distance of 30 mm (1.18 in.) from each other.

 Cables must be bound tightly and neatly. The sheaths of cables must not be damaged.

 Cable ties must face the same direction, and those at the same horizontal line must be in

a straight line.

 The excess of indoor cable ties must be cut off. The excess of 5 mm (0.197 in.) of

outdoor cable ties should be reserved, and the cut surfaces must be smooth without sharp

edges.

 After cables are installed, labels or nameplates must be attached to the cables at their

ends, curves, and interconnection positions.

Security requirements

 When laying out cables, avoid sharp objects, for example sharp edges on the wall. If

necessary, use tubes to protect the cables.

 When laying out cables, keep cables away from heat sources, or use heat insulation

materials to insulate the cables from the heat sources.

 Reserve a proper distance (0.1 m [3.937 in.] is recommended) between equipment and

cables especially at the cable curves to protect the cables and equipment.

Indoor cabling requirements

 Route each cable into the room through the feeder window.

 Reserve drip loops for all cables outside the feeder window before routing them into the

room. Ensure that the radiuses of the drip loops are greater than or equal to the minimum

bending radiuses of the cables.

 When routing a cable into the room, ensure that a person is assisting you in the room.

 Apply waterproof treatment to the feeder window.

Outdoor Cabling Requirements

 Protect outdoor cables against potential damage. For example, thread the cables through

tubes.

 Cables to be protected include AC power cables, transmission cables, and cables laid out

underground.

 Use cable clips to secure cables outdoors.

 Arrange cables neatly along the routing direction and use cable clips to secure the cables.

 Determine the positions where the clips are installed according to the actual situation.

For example, 7/8" feeders are secured with clips at an interval of 1.5 m (4.92 ft) to 2 m

(6.56 ft), and CPRI fiber optic cables and power cables are secured with clips at an

interval of 1 m (3.28 ft) to 1.5 m (4.92 ft). Ensure that the clips are evenly spaced and in

the same direction.

 When fastening cables with a clip, ensure that the cables are aligned neatly and are

routed through the holes in the clip. Do not stretch the cables too tightly.

 When using clips to secure cables, tighten the screws on the clips after all cables are

arranged and laid out.

Special Cabling Requirements

Cabling of PGND cables

 PGND cables for a base station must be connected to the same ground bar.

 PGND cables must be buried in the ground or routed indoors.

 The external conductor of the coaxial wire and the shield layer of the shielded cable must

have proper electrical contact with the metal surface of the equipment which they are

connected to.

 PGND cables and signal cables must be installed separately. A certain distance must be

reserved between them to prevent interference from each other.

 Switches or fuses 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.
