Cabling Cabling principles principles

2.1

Stand-alone BTS cabling principle There are two types of cable entries in the Nokia Flexi WCDMA BTS: internal and external. The internal cable entries are located between the modules, and the external cable entries are installed on the sides of the modules.

Cabling principles

Caution Incorrect cables and seals may not provide secured weather protection. In outdoor installations, including the outdoor cabinet, use only tested IP55 class outdoor cables with seals provided by Nokia. This is also recommended for indoor installations.

Tip Start the cabling from the System Module. It is easier to route the excess cable in other modules than the System Module.

Cable routing when System Module and RF Module are on separate plinths

In wall and pole installation options, the RF Module can be installed on a different plinth than the System Module. In that case, all the cabling, including BTS internal cables, should be routed through the lower cable entry whenever possible.


# Nokia Corporation

Wall

DN7094352

Figure Figure 3.

Routing Routing the cables cables on wall wall inst install allatio ation n

The end of the optical cable is bent to 90 degrees for guidance. Do not break the guiding. In case the optical cable bends upwards, make a loop in the RF Module cable bays before routing the cable through the lower cable entry.

10 (43)

# Nokia Corporation


Cabling principles

Caution Overbending the optical cables damages the cables and can detach or damage the connectors. Do not bend optical cables beyond the minimum radius of 70 mm.

Caution Optical cables are fragile. Route optical cables to the left when possible.

2.2

Cabinet cabling principle In cabinet installations, base station external cabling is routed along the sides of the cabinet. Cables are fixed to the cabinet with cable ties. See the following figures for examples on cable routing in cabinet installations.


Note Separate grounding cables for modules are not needed in cabinet installations.

Routing Routing the the cable cables s inside inside the the outdo outdoor or and and indoor indoor cabi cabinet nets s (cable (cable entry on the roof)

To minimise the risk of damaging the cables (for example, water, ice, dirt), the cables should be routed in such a way that they do not lie on the cabinet floor.

The cables are fixed with standard cable ties, except for power supply cables. The fixing of power supply cables is done with special isolating cable ties. In cabinet installations, there are slots on the sides of the cabinet core and on the cabinet roof for tying the cables. The cables are fixed with standard cable ties, except for power supply cables. The fixing of power supply cables is done with special isolating cable ties which are included in the site bag.

The module core is out of the casing, and the transmission sub-module is installed as instructed in the Installing transmission sub-module section. Make sure that the module is grounded.


Caution The power cable must be connected before power is applied to the system.

Connecting antenna jumper cables Purpose

Antenna cables are connected to the antenna connectors in the front panel of the RF Module. The number of cables used depends on the configuration.

Caution Incorrect cables and seals may not provide secured weather protection. In outdoor installations, including the outdoor cabinet, use only tested, at least IP55 class outdoor antenna jumper cables with seals provided by Nokia. This is also recommended for indoor installations.

Connecting internal optical cables Purpose

The optical cables connected between the System Module and each of the RF Modules and the system extension module are used for transmitting signal between modules.


Before you start

Warning Risk of personal injury. Always switch off the laser before detaching the optical fibre from an optical fibre connector marked with a yellow warning triangle.

Caution Overbending optical cables damages the cables and can detach or damage the connectors. Do not bend optical cables beyond the minimum radius of 70 mm.

Caution The LC connector is fragile. Handle it with care.

Caution Optical cables are fragile. Route the optical cables to the left when possible.

26 (43)

Note Before installation, all optical connectors must be cleaned using an optical connector cleaning kit.

Check that the internal cable entry covers are removed as instructed in Connecting internal power cable section.
