Stand-alone BTS cabling principles 1/4

In a stand-alone BTS, the modules are installed in casings and arranged in stack, wall or pole configuration.

Each casing features both internal and external cable entries, through which the cables are routed.

Internal cable entries are located between the casings, and external cable entries are installed on the sides of the casings, all in the front of BTS.

• For weather protection, module ports are covered with protective seals by default. When connecting cables, only remove the seals where necessary and leave the rest in place. Save the seals for future re-use.

• 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 protective boots provided by NSN. These are also recommended for indoor installations.

• In vertical wall and pole installations, all the cabling should be routed through the lower cable entries whenever possible (including internal cables between modules, when more than one plinth is being used).

• Cables should initially angle down from the connectors, so that water or condensa-tion will not reach the connectors. This is particularly important in vertical installations, in cases where the upper cable entries must be used. Cables should make a down-ward “U” before routing upwards.

• Each module should be separately grounded to the plinth (not chained). In instal-lations where more than one plinth is being used, the modules may be grounded to one master plinth which is in turn connected to the main site grounding point; or the modules can each be grounded to its own plinth, and then each plinth is separately connected to the main site grounding point.

In stand-alone installations, the strain on cables is reduced by using

• cable tie points in the cable entries• cable support plates attached to each side of the casing• cable clamps

The cables are fixed with standard cable ties, except for the power supply cables.

The power cables are attached with special isolating cable clamps, which are included in the site delivery.

• For weather protection, module ports are covered with protective seals by default. When connecting cables, only remove the seals where necessary and leave the rest in place. Save the seals for future re-use.

• 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 boots) provided by NSN. These are also recommended for indoor installations.

• In cabinet installations, BTS external cabling should be routed along the sides of the cabinet. There are slots on the sides of the cabinet core and on the cabinet roof for fastening the cables.

• The cables for each module should be routed so that they do not interfere with the installation or removal of other modules.

• To minimize the risk of damaging the cables (from 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 the power supply cables (special isolating cable clamps are provided in the site package).

• Cables should initially angle down from the connectors, so that condensation will not reach the connectors.

• When modules are installed inside a cabinet, no separate grounding is required. The cabinet provides adequate grounding, as it should be connected to the main site grounding point.

Antenna jumper cabling 1/2

1. Remove the protective seal from the relevant antenna cable connector on the RF Module. Store the seal for later use.

2. Push the antenna jumper cable onto the antenna connector.

3. Route the antenna jumper cable through the external cable entry.

4. Tighten the connector to 25 Nm.

Antenna jumper cables are connected to the antenna connectors on the front panel of the RF Module.

The number of cables used depends on the configuration of the RF module. The length of the jumper cable depends on the BTS configuration and the distance of the BTS from the antenna feeder line.

Note: Antenna jumper cables may have a thickness of 1/2” or 3/8”.

The BTS end of the antenna jumper cable must be a right-angle male for connection to the RF Module. Straight connectors are used with the Remote Radio Head.

1/2” antenna feeder cable can be connected directly to the RF Module if a right-angle male connector is used.

Fiber optic principles

SM 9/125 MM 50/125

• Optical fibers operate on the principle of total internal reflection of light.

• Fibers are made from a central core of very pure glass surrounded by an outer layer of less dense glass.

• Fibers are coated with plastic and stranded together to form multicore cables.

• Fibers are very small and light, easy to install in buildings and equipment racks.

• Optical fibers require sophisticated methods to splice them together.

Handling of optical fibers

Warning• Danger of eye damage caused by the invisible laser beam (infrared radiation)!

• Always turn off any laser sources before inspecting fiber connectors, optical components, or bulkheads.

• Always make sure that the cable is disconnected at both ends, or that the card or pluggable receiver is removed from the chassis.

• Always wear the appropriate safety glasses when required. Ensure that laser safety glasses are used and meet current regulations. They must be matched to the lasers used within your environment.

Caution• Optical cables are fragile. Overbending optical cables damages the cables and can detach

or damage the connectors. Do not bend optical cables beyond the minimum radius of 35 mm (diameter of 70 mm).

• Do not put the fiber under permanent tensile stress. This will likely damage it.

• The optical cables feature a plastic guide at the connector end which safely bends the cable 90° to the left for compact yet correct installation. This forced left-hand orientation must be respected when routing the optical cables. Mishandling the cable guide or the connector is likely to damage the optical cable.

• In general, optical cables and connectors are fragile. Handle with care!

Caution: With the high powered lasers now in use for communications systems, any contaminant can be burned into the fibre endface if it blocks the core while the laser is turned on. This burning may damage the optical surface enough that it cannot be cleaned.

When cleaning fibre components, always follow the procedures carefully. The goal is to eliminate any dust or contamination and to provide a clean environment for the fibre optic connection. Remember that inspection, cleaning and reinspection are critical steps which must be done before making any fibre optic connection.

Maintenance of optical fibers

• Optical fibers are sensitive. The presence of contaminants will lower the mechanical strength of the optical fiber and may attenuate the transmission of light in the fibers. Such contaminants may be so small as to be invisible to the naked eye.

• Clean fiber optic components are a requirement for quality connections between fiber optic equipment.

• After removing the protective caps from the LC connector plugs, never touch the ferrules (connector tips) with your fingers or let them make contact with any non-specified surface or material.

• Clean all optical connectors before installation using an optical fiber cleaning kit.

• Always inspect and clean the connectors before making a connection.

• Cleaning the fiber optic equipment is one of the most basic and important procedures for maintaining fiber optic systems.

• Inspection and Cleaning are critical!

Minimum cleaning procedurea) Moisten a lint-free swab or one section of a lint-free wipe with one drop of 99%

alcohol.

b) Lightly wipe the connector tip with the alcohol-moistened swab or wipe.

c) Dry any remaining alcohol from the tip with a dry swab or the dry section of the wipe.

d) Properly dispose of the swab or wipe. Do not reuse.

Caution: With the high powered lasers now in use for communications systems, any contaminant can be burned into the fibre endface if it blocks the core while the laser is turned on. This burning may damage the optical surface enough that it cannot be cleaned.

Maintenance of optical fibers

Comprehensive cleaning procedure

General cleaning process

Complete these steps:

1. Inspect the fiber connector, component, or bulkhead with a fiberscope.

2. If the connector is dirty, clean it with a dry cleaning technique.

3. Inspect the connector.

4. If the connector is still dirty, repeat the dry cleaning technique.

5. Inspect the connector.

6. If the connector is still dirty, clean it with a wet cleaning technique followed immediately with a dry clean to ensure no residue is left on the endface.

When the cabling is inverted,TX wires induce a signal into the RX wires

When the two wires of a twisted pair are incorrectly used for different directions (TX and RX), the principle of balanced signals will NOT have its positive effect of eliminating common mode interfering signals.

On the contrary, the two signals (TX+RX) will interfere with each other, and the longer the cable, the greater the interference. Signal quality will be degraded (bit errors).

Also alarm management is affected: In case one end of the cable is disconnected from the terminal, the alarm “loss of signal” would be expected. But due to induction from the TX to the RX wire, there might be an incoming signal detected. No alarm at all or for instance “frame alignment lost” would be generated instead.

Feederless and distributed site cabling

• Flexi WBTS feederless or distributed site solution refers to a configuration where the System Module and RF Modules or Remote Radio Heads are installed apart from each other.

• The distance between the System Module and Radio modules can vary from 2 m up to 15 km.− With multi-mode optical cables and transceivers, the distance can be up to 200 m.

− With single-mode optical cables and transceivers, the distance can be up to 15 km.

• The optical cabling options are clear-cut. The greater complexity of feederless sites resides in the power distribution options for the Radio modules (see following slide).

Feederless and distributed site power feeding 2/2

• If power feed for a Radio module is provided by the System Module, the maximum distance is about 100m, depending on the amount of power needed and the type of cable used.− The standard 2m power cable must be retained at each end for IP55 protection.

− The connection between the 2m cable and the heavy-duty DC power cable must be made in a Flexi System External OVP assembly (FSEC) to protect the modules against surge pulses in the power feeding line. (For information about FSEC installation, refer to the relevant documentation.)

− The connection between the 2m power cable and the DC power feed cable could also be made in some third-party IP55 and overvoltage protected box.

• If power feed for a Radio module is provided locally, there are several options:− With the Single RF Module, the integrated FPAB AC/DC converter can be used – compact solution but no BBU available.

− With any RF Module (or even Remote Radio Head), the FPMA power module with AC/DC converter can be used, with or without BBU.

− With any RF Module or RRH, DC power can also be provided through a third-party AC/DC system or some other local site solution. (But IP55 protection must not be compromised.)

− The System Module will have its own power feed solution – FPMA, FPRA, MIBBU, or third-party system.

System Extension Module cabling

• The System Extension Module and the Flexi System Module are interconnected with two optical cables via their BB-EXT optical interfaces (tags 5 & 6).

• The System Extension Module derives its power from the System Module’s BB-EXT power connection.

− Power is routed to the System Extension Module’s external power feed connector (tag 3).

• No other interface is in use on the System Extension Module. It is fitted with a dummy transport unit. Its only function is to provide expanded base-band processing power.

• System Extension Module interface connections are physically identical to those of the System Module.

GPS Mediator FSEG cabling

• Flexi System External GPS Mediator (FSEG) is used for providing an IP55 protected space for powering and connecting the GPS module (GPS Antenna Kit FYGA) to the BTS system.

• FSEG is used only with the FSMB when GPS synchronization is needed. FSEG can be installed alongside Flexi BTS in a variety of flexible alternatives.

• FSEG performs the following functions:− Transforming operating voltage to FYGA (from -48VDC to +12VDC)− Mediating GPS clock signal from FYGA to the BTS system− Providing overvoltage protection

• FSEG requires a DC power con-nection from the Power Distribution sub-module in Flexi System Module and a timing connection to the FSM Synchronization input.

• BTS Sync In (MDR-26) connects to synchronization interface of FSMB.

• GPS Module (MDR-26) connects to FYGA GPS interface.

• BTS PSU (screw terminal, AWG8 cable) connects to -48VDC output from FSMB.

External alarm cabling

There are two options for cabling external alarms in Flexi BTS:− Alarm cable for the Flexi System External Alarm Module (FSEB)− Flexi System Alarm cable (FSAA) for all other external alarm applications

• The FSEB external alarm cable interconnects the System Module and the optional FSEB external alarm box.

• The FSEB module provides IP55 protected screw terminals – 12 for alarm inputs and 6 for control outputs – and power for the Flexi Cabinet Fire Detector (FCDA).

• FSEB can be installed along-side Flexi BTS in a variety of flexible alternatives.

• In outdoor installations, the cable lead-ins must be facing downwards, or to the left or right, to meet the IP55 standard.

• The Flexi BTS connection to FSEB is made via the left-most cable lead-in.

FSEB module cabling

• The FSEB external alarm cable (included in the FSEB delivery) features at one end a MDR-36 connector (IP55 protected) for the EAC connection to the System Module, and at the other end a 37-pin Sub-D connector that plugs into the leftmost connector X1101 (ESM) on the FSEB board (see previous slide).− The other two Sub-D37 connectors on the FSEB (X4101/ EACX-I and X4102/ EACX-II) can be used to import external alarms from older types of ex-Nokia BTS’s (e.g., UltraSite WBTS)

− Note that external alarms 13-24 (connector EACX-II) are reserved for future use in WCDMA mode.

• The individual external alarm cables are inserted through the right-side cable lead-ins on the front panel, and are connected to the various screw terminals on the FSEB board.− External alarm inputs 1-6 (EXT_AL1…EXT_AL6) are connected to terminal block X4106 and the corresponding ground wires are connected to terminal block X4107 (the X connectors are marked on the bottom of the FSEB PCB).

− External alarm inputs 7-12 (EXT_AL7…EXT_AL12) are connected to terminal block X4108 and the corres-ponding ground wires are connected to terminal block X4109.

• If external control outputs are to be used, their cables are also inserted through the right-side cable lead-ins and are connected to screw terminals on the FSEB board.− Control lines 1-6 (EXT_CO1…EXT_CO6) are connected to terminal block X4104 while the second wire ineach pair is connected to terminal block X4105 (5V output).

− The control outputs are open-collector type. To ensure correct operation, they require a pull-up resistor (2-6 kΩ, 5 kΩ recommended) or else a relay (providing galvanic isolation) connected to +5V.

− Note that the maximum recommended distance for the control lines is 15 m (but these are rarely used).

External alarm cabling with FSAA cable

If the FSEB External Alarm Module is not used, then external alarms are connected to Flexi BTS using the Flexi System Alarm cable (FSAA).

• The FSAA cable features at one end a MDR-36 connector (IP55 protected) for the EAC connection to the System Module, and at the other end a 37-pin Sub-D connector that can be used to connect to − FSEB External Alarm Module, if a longer (15 m) cable connection is needed− external alarm cable from older types of ex-Nokia BTS’s (e.g., UltraSite or Talk-Family)− another alarm system or distribution frame (DDF)

• When the FSAA cable is connected to an alarm control box or to a DDF, the Sub-D37 connector is cut off and the individual wire pairs are connected to the terminals.

− The wire connections for external alarms and controls should be made according to the pin color mapping on the following slide.

− Note that the maximum recommended distance for control lines is 15 m (but these are rarely used). Distances for alarm lines can be longer.
