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.
