Cabling principles


2 Cabling principles 2.1 Stand-alone BTS cabling principle This section describes the cabling principles of 3U modules. For Remote Radio Head cabling instructions, see Installing and Cabling Flexi Multiradio Remote Radio Heads. There are two types of cable entries in Flexi Multiradio 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. Table 2

NOTICE:

t

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

t

Tip: RF Module ports are covered with seal caps by default. When connecting RF Module cables, only remove the seal caps where necessary and leave the rest in place.

t

Tip: In left-facing vertical installations, the optical cables can be routed in the gap between the top of the module and the casing to meet the 70 mm bending radius.

Incorrect cables and seals may not provide appropriate ingress protection. Use only tested IP65 class outdoor cables with seals provided by Nokia. This is required for both indoor and outdoor installations, including the outdoor cabinet.

DN7038109

Issue: 14


Cabling principles

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. Figure 11

Issue: 14

Routing the cables on wall installation (Dual RF Modules)

DN7038109

19

Cabling principles


Figure 12

Routing the cables on wall installation (3-sector RF Modules)

The end of the optical cable is straight or bent 90 degrees to the left or right, depending on the cable type used. 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. If using 3-sector RF Modules in wall and pole installations, coil up the excess cables and fix them on the sides of the module casings with cable ties.

w

20

NOTICE: Overbending the optical fiber cables damages the cables and can detach or damage the connectors. Do not bend optical fiber cables to a radius smaller than the minimum radius of 70 mm (2.76 inches) for cables with a diameter 7 mm (0.28 inches) or 50 mm (1.97 inches) for cables with a diameter 5 mm (0.20 inches).

DN7038109

Issue: 14


w

NOTICE: Optical cables are fragile. Always choose the optical cable type depending on the direction you want to route cables. For additional information on available optical cable types and its bending directions, see Flexi Multiradio BTS and Flexi Multiradio 10 BTS cables and SFPs in the Flexi Multiradio Base Station and Flexi Multiradio 10 Base Station Optional Items Description document.

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.

w

NOTICE:

g

Note: When modules are installed inside a cabinet, no separate earthing (grounding) is required. The cabinet provides adequate earthing (grounding).

t

Tip: RF Module ports are covered with seal caps by default. When connecting RF Module cables, only remove the seal caps where necessary and leave the rest in place.

Incorrect cables and seals may not provide appropriate ingress protection. Use only tested IP65 class outdoor cables with seals provided by Nokia. This is required for both indoor and outdoor installations, including the outdoor cabinet.

To minimize 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.

22

DN7038109

Issue: 14


Cabling principles

The cables should first go down from the connector so that if there is condensed water, it will not reach the connectors. If using 3-sector RF Module, fix the optical cables to the module handles in cabinet installations. Then make a loop of the excess cable and fix it with a cable tie. Figure 15

The cables are fixed with standard cable ties, except for the power supply cables. The fixing of power supply cables is done with special isolating cable clamps, which are included in the accessory bag. 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 the power supply cables. See the following figure for the cable supports in the outdoor cabinet.

WARNING! Risk of short circuit. Make sure the main site switch is in the OFF position before you connect the external power cable. NOTICE: Incorrect cables and seals may not provide appropriate ingress protection. Use only tested IP65 class outdoor cables with seals provided by Nokia. This is required for both indoor and outdoor installations, including the outdoor cabinet. The power cable must be connected before power is applied to the system. It is recommended that wire end ferrules be used. Procedure 1

Tip: If using a Dual or Single RF Module, the cable is routed via an internal cable entry when System and RF Module are installed on the same plinth. If System and RF Modules are installed on separate plinths (for example, in wall or pole installations), the cabling between those modules is routed via external cable entries. If using a 3-sector RF Module, always use the external cable entry.

Procedure 1

If using a Dual or Single RF Module, remove the internal cable entry covers from all the modules except the top module.

2

Remove connector seals from power cable connectors in both System and RF Modules. Store the seals for later use.

•

There must be two available power output connectors on the System Module. Cable FPCA (472806A) (included in the RF Module delivery) must be connected to the two open connectors on the System Module.

The following requirements apply if power is fed from an external power source: –

The allowed diameter of shielded or jacketed cables is 6-25 mm (0.24-0.98 in.).

–

The allowed cross section of individual DC wires is 6-25 mm2 (10-4 AWG) at the DC terminal. It is recommended that 25 mm2 (4 AWG) wires are capped to avoid loose strands. If thicker DC wires are required, then an FSEC/FSES or other IP65 DC distribution box is required to reduce the cable thickness at the module. Recommended DC cable lengths, thicknesses, and type are provided in Feederless site and Distributed site solution requirements. The DC connector has three screw terminals. The outer terminals are for (+) and (-) wires. The middle terminal is for grounding the shielded DC cable braid.

4.5 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. The System Module supports optical cables in three length ranges: 1. 0 - 13 km (depending on the RF HW version, the values might vary as follows: 0 - 10 ... 13 km) 2. 13 - 26 km (depending on the RF HW version, the values might vary as follows: 10 ... 13 km or 20 ... 26 km) 3. 26 - 39 km (depending on the RF HW version, the values might vary as follows: 20 ... 26 km or 30 ... 39 km) The RF Modules must be connected to the System Module with a fiber from the same length range. Note that in case of RF chaining, the optical cable length from the System Module to any RF Module in chain must remain in the same length range. In case of RF Modules chaining, the length range is the total optical path length between the System Module and the last RF Module in chain.

g

Note: Note that the first fiber length ranges vary between different radio HW versions: • •

• • •

FRGG, FRGF, FRID: ~ 15 km (no Dynamic system timing support, this is the total max. length) FRCA, FRCB, FRDA, FRDB, FRFA, FRFB, FRGC, FRGD, FRGJ, FRGK, FRGL, FRGM, FRIA, FRIB, FRIC: ~ 15.8 km (no Dynamic system timing support, this is the total max. length) FRHA, FRIE, FRGP, FRMA, FRMD, FRLB, FRMB, FRGQ, FRHB, FHPC: ~ 10..12 km FXDA, FXDJ, FXEA, FXCA, FXFB, FHDA, FHEA, FHEB, FHEF, FHCA: ~ 10..11 km FXCB, FXCE, FXDB, FXEB, FRGS, FRGT, FXFC, FXJB, FHDB, FHGB, FHEB, FHEG, FHEJ, FRIG, FRHD, FRHE: ~ 10..11 km

For example, if the only external alarm support needed at the site is the ExtraTalk or UltraSite alarms and fire detector support is not needed, then the FSAA cable can be used. The FSAA cable connects directly to UltraSite and ExtraTalk alarm cables with the Dconnector. The FSAA cable can be connected to other alarm systems by cutting the Dconnector and connecting the wires to the terminals. For pin colour mapping, see FSAA pin colour mapping. The limitation of 15 m is only related to the control output which is rarely used or not used at all. The external alarm sensor can be more than 15 m away from the module. Before you start • •

If an FSEB is used, the FSEB must be installed as instructed in Installing Flexi System External Alarm (FSEB). If an FSEB is not used, the Flexi System Alarm Cable (FSAA) is needed.

The external alarms cable is optional.

Before you start The installation of the optical cable between the System Module and RF Module or Remote Radio Head requires two small form-factor pluggable (SFP) optical transceiver units (included in the RF Module delivery) that are plugged into both the System and RF Module or Remote Radio Head. A multimode adapter (included in the 100 m optical cable delivery) is required when two optical cables are connected together. Optical cables are used for creating an optical interface between the System and RF Module or Remote Radio Head. The length of the cables is 50 m or 100 m. In case you need a cable of a specific length, shorten the cable by cutting and splicing it to the required length. In distributed site installations, the System Module and RF Module or Remote Radio Head can be attached to the existing fiber network by using single mode components, cables, and single mode transceivers. The System Module and RF Module or Remote Radio Head are connected with a 2-metre single mode cable to a long optical cable (up to 15 km).

Connecting Flexi Power Rectifier (FPRA) alarms for Flexi Multiradio BTS

6 Connecting Flexi Power Rectifier (FPRA) alarms for Flexi Multiradio BTS 6.1 Overview of connecting Flexi Power Rectifier (FPRA) alarms These instructions show how to connect the alarm cables from the A version of Flexi Power Rectifier (FPRx) to Flexi Multiradio BTS. For full details on the installation of the FPRA, see Flexi Power Rectifier documentation on NOLS. Note that the FPRA delivery does not include any alarm cables. The required cables are either supplied with the interconnecting units (Flexi System External Alarm (FSEB) and/or Flexi Cabinet Site Support Module (FCSA)) or must be ordered separately depending upon the configuration. When using Flexi Power Rectifier (FPRA) with Flexi Cabinet Site Support Module (FCSA) in an outdoor application, there are two different cabling configurations for Flexi Multiradio BTS which can be used depending upon the number of alarms signals required by the user. See Connecting 3 FPRA alarms and 4 FCSA alarms and Connecting 6 FPRA alarms and 4 FCSA alarms. The FPRA is a 6kW output power AC rectifier package made up of three individual 2kW AC/DC power modules operating in a parallel mode configuration. The FPRA produces a positive earthed –54VDC as a respective BTS operational supply voltage rail and for site battery charging. Figure 53

FPRA front view

The FPRA also includes a Power Distribution Assembly (PDA), which contains a fully integrated battery protection LVD, load/battery circuit breakers. Alarm signals to the BTS Alarm interface are connected to the PDA unit via a pull out Alarm Interface Card.

Note: Only optical cables are shown in the following figures. For stack configurations, 2 m (6.6 ft) optical cable can be used for the configurations below and smaller. If the distance between the 80 W RF Module and System Module is greater than the examples below, a longer cable is required. Figure 65

9.1 Routing optical cable around the stack Steps Procedure

g

86

1

Route the optical cable through the System Module cable entry and connect it to the System Module port.

2

Route the other end of the optical cable around the stack and through the RF module cable entry. Connect it to the RF module port. Note: When routing cable behind modules, avoid the airflow path. Cable can be routed below the first casing as shown in Figure 69: Routing optical cable or between casings as shown in Figure 75: Securing optical cables on the back side of the module.
