Head Description
8 Power requirements and output power
8.1 RF Module power requirements and output power
DC cable requirements for 60 W RF Modules
48 VDC power can be fed to the RF Module directly from the System Module or from an
external power source. In both cases, the internal power cable with boot included in the
RF Module delivery must be connected to the RF Module to provide IP65 protection.
•
•
•
If the cable path between the System module and RF Module is less than 2 m then
the internal power cable included in the RF Module delivery is connected directly to
the System module and RF Module. The optional 4 m (13.1 ft) power cable FPTA
472246A can also be used between the System Module and RF Module.
If the cable path between the System Module and RF Module exceeds 4 m (13.1 ft),
then a pair of FSEC/FSESs (Flexi System External OVP) must be installed between
the System module and RF Module. For details, see Creating Flexi Multiradio BTS
Site Configurations in respective system documentation.
For all RF Modules with or only modules with the 3-terminal DC connector if 48 VDC
power is supplied to the RF module from an external power source, then an
FSEC/FSES must be installed between the external power source and the RF
module. The internal power cable included in the RF module delivery must be
connected from the RF module to the FSEC/FSES.
DC cable requirements for 80 W RF Modules
The DC cable is not included in the 80 W RF Module delivery. 48 VDC power can be fed
from a System Module or directly from an external power source.
If the cable path between the System Module and RF Module exceeds 10 m (32.8 ft),
then a FSEC/FSES (Flexi System External OVP) must be installed next to the System
module or external power source. For details, see Creating Flexi Multiradio BTS Site
Configurations in respective system documentation.
OVP DC ampacity must not be lower than PDU fuse rating.
g
If 80W RF Module is used with FSMC/D/E (FPFB 30A PDU), FSMF (FPFD
A.103 30A PDU), or FPFC A.102 30A PDU then the rules in
Table 10: DC Cable Requirements for 80 W RF Modules apply.
For newer FPFD PDU version A.204 or FPFC A.203 with 43A label a single DC
cable is sufficient and dual DC cable must not be used. Conductor wire
diameter of DC cable need to be selected based on the PDU fuse rating.
With ESMB or ESMC single cable is sufficient for all 80W RFM modules as 36A PDU is
used.

Total configured output power is the total power for all three branches. For example, a 2+2+2 @ 40 W is
equal to 240 W.
The following power cables are available: FPCA 472806A (Dual, 2 m, 6.6 ft), FPCB 472817A (Single, 2 m,
6.6 ft), FPCC 472823A (Single, 2 m, 6.6 ft), FPTA 472246A (Single, 4 m, 13.1 ft). The dual power cable
requires two available PWR outputs on the System Module or PDU (excluding PWR AUX). It is
recommended to use the next available connectors in sequence. The FPCC and FPTA require removing
the connector from one end. Consider future expansion when choosing single or dual power cables.

Requirements if power is supplied from an external source
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 (0.24-1 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 the section
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.

RF Module and RRH Module LED indications
10 RF Module and RRH Module LED indications
The Flexi Multiradio RF Module and Flexi RRH Module have two tricolor LEDs on the
front panel to indicate the operational status of the module and all fault conditions during
operation. A blinking red LED does not always require removing the module.
The Flexi Multiradio RF Module LEDs are:
•
•
Module Status - indicates the status of the RF Module core functional block
Fan/TX Status - indicates the fan and TX status
The Flexi Multiradio RRH Module LEDs are:
•
•
g
Module Status - indicates the status of the RRH Module core functional block
TX Status - indicates the TX status of the RRH Module
A Red, blinking LED does not necessarily mean hardware failure. Always
perform troubleshooting before replacing the module.
You can identify faulty Flexi Multiradio BTS modules with respective Flexi BTS Site
Manager. In the Alarms window of respective Flexi BTS Site Manager, you can see the
object that the alarm refers to in the Object column. It is not always the alarming module
that is faulty, it may also be the connected cable or the interworking module that causes
the alarm.
At the site, you can easily locate the alarming module by checking the color of the LED.
See the LED status indications tables for information of LED status.

Appendix C: Avoiding Passive Intermodulation during
RF Module and RRH operation
13 Appendix C: Avoiding Passive
Intermodulation during RF Module and RRH
operation
In wideband frequencies when several transmitting and receiving signals are sharing
same hardware there could be noted effect called Passive Intermodulation (PIM)
Interference. Using RF Modules might cause a potential risk of generating third-order
intermodulation that results in distortions in own receiver (RX) channel. Antenna Line
Devices (ALD) have important role in preventing Passive Intermodulation generation,
even if used RF Module and RRH performance at the antenna connector complies with
3GPP requirements. Poor PIM performance of ALD might degrade significantly the
reference sensitivity. ALDs, like MHAs, provided by NSN have high PIM requirements.
The risk might be high in the following cases:
•
•
•
maximum bandwidth (BW) used for the carriers is more than 0.5 x duplex separation
of the band
carriers in configuration are wideband in nature (for example WCDMA or LTE), or
combination of wideband and narrow band carriers (for example RF sharing GSMWCDMA or GSM-LTE).
antenna line PIM performance is poor, or not on the required level for the
configuration.
Table 24
Typical reference sensitivity degradation with different Antenna line PIM
performance.

Note

cases
-153 dBc @ 2x43
dBm
~2 dB
Modest degradation, tolerable in many cases
-161 dBc @ 2x43
dBm
~0.2 dB
Minimal degradation, however, difficult to reach on the
typical site environment.
When using wideband carrier configurations where PIM products fall into own receiver
band, it is recommended that antenna line PIM performance is at least -153 dBc
measured with 2 x 43dB test signals.
However, this kind of performance might be very difficult to achieve and maintain over
time in outdoor environment due to mechanisms behind the PIM including corrosion,
oxidation, material imperfections, and defects in workmanship. Some of these
parameters might change, and can degrade performance during operation. Taking that
into consideration, it is highly recommended not to use carrier configurations which are
generating intermodulation results in landing in own receiver channels.
