Core Specifications
Fiber Type:
- Multimode OM2 (62.5/125µm) with bend-insensitive technology
- Some variants may use OM3 (50/125µm) for higher bandwidth
Connectors:
- LC/UPC duplex connectors (industry standard)
- Weatherproof OD (Outdoor) variant available (IP67 rated)
Length Options:
- Standard 2m length (472894A.101FSFL variant)
-
Other lengths likely available (1m, 5m, 10m)
Performance Characteristics
| Insertion Loss: ≤0.5 dB typical at 850nm | Return Loss: ≥35 dB (UPC polished) |
| Operating Temp: -40°C to +70°C (outdoor rated) | Tensile Strength: 100N (maximum during installation) |
| Cable Diameter: 3.0mm ±0.2mm (typical) | Jacket Material: LSZH (Low Smoke Zero Halogen) |
Comparison with Other Nokia Fiber Models
| Model | Type | Length | Connectors | Key Features | Use Case |
| 472894A | MM OM2 | 2m | LC/UPC (OD) | Bend-insensitive, outdoor-rated | RRH/BBU short links |
| 473302A.101 | MM OM2 OD | 100m | LC/OD-LC | Ruggedized, 100m fixed length | FTTA/long-haul |
| DFJ-2M7-NB | MM OM3 (CommScope) | Custom | LC duplex | Nokia-compatible, LSZH jacket | Alternative for 472894A |
Notes:
- 472894A is optimal for short, flexible jumps in base stations, while 473302A suits long outdoor runs.
- CommScope’s DFJ series offers higher bandwidth (OM3) but lacks Nokia’s proprietary boots
Installation Guidelines
Pre-Installation Checks
- Verify the cable length (standard 2m for model 472894A.101FSFL) and connector type (LC/UPC duplex).
- Ensure tools are ready: fiber cleaver, alcohol wipes, and a dust cap for unused ports.
Connector Handling
- Clean LC connectors with alcohol wipes before insertion to avoid signal loss. Hold the connector vertically during cleaning.
- Bend radius: Maintain ≥15× the cable diameter (e.g., 45mm for a 3mm cable) to prevent fiber damage.
Outdoor Installation (if applicable)
- Use IP67-rated sealed boots for outdoor deployments to protect against moisture and dust.
- Ground the cable properly if connecting to RRU/BBU to mitigate EMI.
Connection Steps
- Align LC connectors with Nokia equipment ports (e.g., AirScale BTS or Flexi modules) until they click into place.
- Secure excess cable with velcro straps (avoid zip ties to prevent crushing).
Testing
- Use an optical power meter to verify insertion loss (should be ≤0.5 dB for OM2).
Usage Notes
- Compatibility: Designed for Nokia AirScale/Flexi BTS and RRH interconnections.
- Maintenance: Regularly inspect connectors for dirt; re-clean if signal degradation occurs.
