MPO Polishing Guide: Achieving Optimal Fiber Performance
MPO (Multi-Fiber Push-On) connectors are widely used in high-density fiber optic networks. Proper polishing of these connectors is essential to ensure efficient data transmission, minimal signal loss, and long-term performance. Here’s a comprehensive MPO Polishing Guide to help you achieve the best results.
Why Proper MPO Polishing Matters
Minimize Signal Loss: Proper polishing ensures the fibers are aligned correctly, allowing for minimal light loss during transmission.
Improve Connector Performance: Smooth, well-polished fiber ends guarantee high-quality connections, reducing the chances of signal interference.
Maximize Connector Lifespan: Correct polishing helps extend the life of the MPO connectors by preventing surface damage and degradation.
Required Materials for MPO Polishing
Polishing Films:Silicon Carbide (15µm and 3µm): For coarse and intermediate polishing stages.
SC1A Special Film: For fine fiber height adjustment.
Flocked CE0.5 Film: For final polishing to achieve a high-gloss, smooth finish.
Polishing Pads/Plates: Special fixtures designed for MPO connectors.
DI Water: To lubricate the polishing process and prevent contamination.
Inspection Equipment: Fiber scope or microscope for inspecting the fiber ends after polishing.
Step-by-Step MPO Polishing Process
Step 1: Coarse Polishing with Silicon Carbide (15µm)
Objective: Remove excess material and shape the connector for proper fiber alignment.
Materials:Silicon Carbide 15µm Polishing Film MPO model SC15B Fixture DI Water
Process:Secure the MPO connector in the SC15B polishing fixture.Apply DI water on the polishing film and connector to lubricate the surface.Polish the connector with moderate pressure to remove material and prepare the fiber ends for finer polishing.Regularly check for rough spots or excess material to ensure an even surface.
Step 2: Intermediate Polishing with Silicon Carbide (3µm)
Objective: Further refine the fiber surface and reduce scratches left from the coarse polishing step.
Materials:Silicon Carbide 3µm Polishing Film MPO model SC3D Fixture DI Water
Process:Replace the 15µm film with 3µm Silicon Carbide.Place the connector in the SC3D fixture for better alignment during the polishing.Apply DI water to reduce friction and prevent overheating.Use moderate pressure to smooth the surface and prepare it for the next step.
Step 3: Fiber Height Adjustment with SC1A Special Film
Objective: Ensure all fibers are properly aligned for uniform performance.
Materials:SC1A Special Film SC1A Polishing Fixture DI Water
Process:Replace the 3µm film with SC1A Special Film, designed for fiber height adjustments.Secure the MPO connector in the SC1A fixture.Apply light pressure to make micro-adjustments to the fiber heights, ensuring uniformity.Use DI water for smooth, clean polishing to prevent scratches or inconsistencies.
Step 4: Final Polishing with Flocked CE0.5 Film
Objective: Achieve a mirror-like finish to ensure high-quality light transmission and minimal signal loss.
Materials:Flocked CE0.5 Film MPO Polishing Fixture DI Water
Process:Replace the SC1A Special Film with Flocked CE0.5 Film.Place the MPO connector into the polishing fixture.Apply DI water and use light pressure to polish the fibers to a high-gloss finish.Ensure the fibers are smooth and free from any marks or scratches that could affect performance.
Inspection and Quality Control
After completing the polishing process, it’s critical to inspect the connectors to ensure the polishing is done properly.
Fiber Scope or Microscope: Use an inspection tool to examine the connector for defects like scratches, chips, or uneven fiber heights.
Check for Flatness: The fiber ends should be perfectly flat with no convex or concave areas, which could impact light transmission.
Verify the Finish: The fiber ends should have a mirror-like finish, free of visible defects, ensuring efficient data transmission.
Tips for Successful MPO Polishing
Consistency: Keep a consistent polishing pressure across all steps to avoid uneven results.
Proper Alignment: Always ensure the MPO connector is aligned properly in the fixture to maintain uniformity.
Use of DI Water: Ensure Deionized (DI) water is used throughout the process to prevent contamination or scratching.
Frequent Inspections: Regularly inspect your work at each stage to catch potential issues early.
Conclusion
Proper MPO polishing is essential for high-performance fiber optic networks. By following this guide and using the right materials and techniques, you can ensure that your MPO connectors are polished to the highest standards. The result will be optimal signal integrity, minimal light loss, and longer-lasting connections in your fiber optic infrastructure.
