Nokia RRU FXEF — Flexi RFM 3-Pipe 1800 (3×80 W, LTE/GSM Band 3)

Product overview

FXEF is a 3-TX (3-pipe) outdoor Flexi RF Module for 1800 MHz (Band 3) macro sites. It supports GSM and FDD-LTE, delivering 3 × 80 W = 240 W total RF output in one enclosure, with sector-diversity receive paths and integrated optical interfaces. 

Common part number seen in channel: 473439A (FXEF, 3-pipe 1800 240 W). 

Key features (validated)

• RF power: 3 × 80 W (total 240 W). 

• Technologies: GSM, FDD-LTE (FXEF is listed as supported from LTE 16A). 

• Frequency ranges: TX 1805–1880 MHz, RX 1710–1785 MHz. 

• Instantaneous / filter bandwidth: 75 MHz DL/UL (supports LTE or LTE/GSM sharing). 

• MIMO: 2TX per sector (supports 2×2 MIMO). 

• Antenna-line devices: AISG 2.0 via specific antenna ports; CWA supported for non-AISG installs; ALD supply 12 V/25 V, up to 30 W per port. 

• Interfaces / connectors:

• 6× antenna ports (7/16″)

• 3× RxO (RF output) ports (QMA)

• 1× RET (8-pin circular)

• 1× EAC external alarm (MDR36)

• 3× optical SFP (3–6 Gbps)

• Grounding studs
  All per the FXEF interface table. 

• Ingress protection: IP65; outdoor pole/wall/rack/floor mounting kits available (FMFA/FPKA/FPKC). 

Electrical & environmental

• Nominal supply: –48 V DC; nominal input range –40.5…–57.0 V; extended –36…–60 V. 

• Operating temperature: –35 °C to +55 °C (at +55 °C max RF power may be limited). 

• Typical power consumption: depends on carrier config; Nokia table shows increasing draw with wider LTE BW (e.g., 20+20 to 80+80 MHz). Use site-specific planning values from the FXEF power table. 

Mechanical

• Core RFM dimensions (approx.): H 118 mm × W 441 mm × D 404 mm; with front covers the overall width/depth increase (see table).

• Weight: ~25 kg. 

Typical applications

• 1800 MHz macro-layer coverage/capacity (LTE/GSM).

• Swap/modernization where a single 3×80 W module replaces multiple discrete radios.

• Sites needing 2×2 MIMO with LTE/GSM sharing capability on Band 3.
