The steel pipe or fire-resistant rigid polyvinyl chloride pipe should be used for the cable
duct or for routing cables. The cross-sectional usage of the cable duct should be 30% to
50% and that of the pipe for routing cables should be 25% to 30%.
Cables are placed away from sharp objects or wall burrs. If these positions are inevitable,
protection pipes are required for the cables.
Cables are routed away from heat sources, or heat-insulation materials are added
between cables and heat sources.
Cables are routed away the cooling vents of the RHUB.
A clearance is reserved at turns of a cable or the position close to a device, facilitating
cable and device maintenance. The recommended clearance is about 0.1 m.
Requirements for Special Cables
Ethernet Cable
A maximum of 100 Ethernet cables can be bundled if no PVC pipes are used. If pipes are
used, a maximum of 24 Ethernet cables can be led through a pipe. In this case, ensure
that 1/3 space inside the pipes must be vacant.
The point at which an Ethernet cable is bundled must be spaced 400 mm or less from the
Ethernet port on an RHUB.
For the RHUB used in the elevator engine room on the rooftop, generator set for the
subway engine, and equipment room with central air conditioning, Ethernet cables must
be led through metallic conduits that are reliably grounded at both ends.
Power cable
Positions for routing power cables meet requirements of the engineering design.
Cables are routed only by qualified and trained personnel before all preparations are
made.
Cables are routed in an untangled and orderly fashion.
PGND cable
PGND cables are buried in the ground or routed indoors. They cannot be routed
overhead before they are routed into the equipment room.
Outer conductors of coaxial cables and both ends of the shield layers on shielded cables
are in proper electrical contact with the metal surface of the equipment to which they are
connected.
PGND cables and signal cables are installed in an untangled and orderly fashion. A
certain distance is reserved between them to prevent interference from each other.
Fuses or switches are not allowed on PGND cables.
Other devices cannot be used for electrical connections of PGND cables.
All the metal parts in the equipment are reliably connected to the ground terminal.
Optical cable
Cables are routed in an untangled and orderly fashion.
Optical fibers cannot be bound at turns.
Optical fibers cannot be stretched with too much force or stepped on, and they are far
away from sharp objects. Heavy objects cannot be placed on optical cables.
When optical cables are routed, the extra length of the cables is coiled around special
devices, such as a fiber coiler.

Even strength is applied when optical cables are coiled and optical cables cannot be bent
in a forcible manner.
Vacant optical connectors are covered with dust-proof caps.
Fiber optic cables cannot be squeezed by the cabinet door when routed through the
cabinet.
If optical cables need to be routed on the tower platform, the optical cables are routed
along the inner side of the guard rail and the distance between the guard rail and the
cable is the shortest one.
If optical cables need to be routed close to a device on the tower, the optical cables are
secured to the guard rail or pole with cable clips and the device cannot be far away from
the position for securing the optical cables.
If the optical cable close to a device on the tower is too long, the optical cables are
wrapped and secured to the tower.

Bending radius
The bending radius of a 1/4'' jumper, a 1/2'' softer jumper, and a 1/2'' common jumper
must be longer than 35 mm, 50 mm, and 127 mm, respectively.
The bending radius of a power cable is at least three times the diameter of the cable.
The bending radius of a signal cable must be at least five times of the diameter of the
cable.
Cable binding
Cables of the same type are bound together.
Different types of cables must be separately routed with a minimum spacing of 30 mm
and cannot be entangled.
The cables are bound tightly and neatly and the sheaths of the cables is intact.
The cable ties face the same direction and all cable ties bound at similar positions must
be in a straight line.
The extra length of each indoor cable tie must be cut off. A slack of 5 mm is reserved for
each outdoor cable tie before the extra length is cut off. All cut surfaces are without
sharp edges.
Labels or nameplates are attached to both ends, joints, or turns of cables after they are
installed.
Safety
The steel pipe or fire-resistant rigid polyvinyl chloride pipe should be used for the cable
duct or for routing cables. The cross-sectional usage of the cable duct should be 30% to
50% and that of the pipe for routing cables should be 25% to 30%.
Cables are placed away from sharp objects or wall burrs. If these positions are inevitable,
protection pipes are required for the cables.
Cables are routed away from heat sources, or heat-insulation materials are added
between cables and heat sources.
A clearance is reserved at turns of a cable or the position close to a device, facilitating
cable and device maintenance. The recommended clearance is about 0.1 m.

This section describes how to install an Ethernet cable.
Prerequisites
The Ethernet cable must be of Category 5e (enhanced) or higher. In addition, its crosssectional area must be 24 AWG or larger and frame spread rating must be CM or higher.
The Ethernet cables can be straight-through cables or crossover cables.
With the internal PoE module providing power, the maximum length of an Ethernet
cable is 100 m. With the Extender, the distance of the pRRU3901 and RHUB can be
extended by the Extender up to a total distance of 200 m.
Ethernet cables are not delivered, and they must be prepared onsite. You need to use a
network cable tester to test the Ethernet cable connection.
Context
The Ethernet cable has the following functions:
Provides power supply for the pRRU3901 when the cable connects the CPRI_E0 port on
the pRRU3901 to the RHUB.
Transmits CPRI signals between an RHUB and a pRRU3901.
Provides Wi-Fi services for the pRRU3901 when the cable connects the GE port on the
pRRU3901 with three transmission ports to the AC.

NOTICE
If the pRRU3902 is installed on a ceiling, the temperature of the ceiling may increase by a
maximum of 30 degrees. Therefore, whether a pRRU3902 can be installed on a ceiling
depends on the ceiling material.
Procedure
Step 1 Determine the position for installing the pRRU3902 based on the construction blueprint and
the clearance requirements.
NOTE
For details about the clearance requirements, see 8.1.3 Space Requirements.
Step 2 Place the mounting bracket in the installation position against the ceiling. Then, level the
mounting bracket and use a marker to mark four anchor points. See Figure 8-11.

8.3.5 Installing a pRRU3902 on a Keel
This section describes how to install a pRRU3901 on a keel. If a suspended ceiling plate
cannot bear the pRRU3902, the pRRU3902 can be installed on the keel on the ceiling. The
standard keel with a width less than 45 mm, instead of the non-standard keel, is
recommended.
Context
Before installing the pRRU3902 on a keel, ensure that the keel is strong enough to bear the
pRRU3902.
The mounting bracket of the pRRU3902 can be installed on the keel of the following
specifications: GBT 11981-2008, JIS A6517-2002, and ASTM C635 C635M-2007. The
installation mode depends on onsite requirements because there are various keels.
This section describes the procedure of installing a pRRU3902 on the keel of JIS
standard used in Japan. The procedure of installing a pRRU3902 on other keels is the
same as that of installing a pRRU3902 on the keel of JIS standard.
The keel used on the ceiling is thin. During installation, fix the mounting kits onto the large
surface instead of the small surface of the keel to prevent distorting the keel.
Procedure
Step 1 Determine the position for installing the pRRU3902 based on the construction blueprint and
the clearance requirements.
NOTE
For details about the clearance requirements, see 8.1.3 Space Requirements.

8.4.5 Installing an Ethernet Cable
This section describes how to install an Ethernet cable.
Prerequisites
The Ethernet cable must be of Category 5e (enhanced) or higher. In addition, its crosssectional area must be 24 AWG or larger and frame spread rating must be CM or higher.
The Ethernet cables can be straight-through cables.
With the internal PoE module providing power, the maximum length of an Ethernet
cable is 100 m. With the Extender, the distance of the pRRU3901 and RHUB can be
extended by the Extender up to a total distance of 200 m.
Ethernet cables are not delivered, and they must be prepared onsite. You need to use a
network cable tester to test the Ethernet cable connection.
Context
The Ethernet cable has the following functions:
Provides power supply for the pRRU3902 when the cable connects the CPRI_E0 port on
the pRRU3902 to the RHUB.
Transmits CPRI signals between an RHUB and a pRRU3902.
Procedure
Step 1 Make the Ethernet cables.
1.

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.

(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.
