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


Required Materials for MPO 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


Inspection and Quality Control

After completing the polishing process, it’s critical to inspect the connectors to ensure the polishing is done properly.

  1. Fiber Scope or Microscope: Use an inspection tool to examine the connector for defects like scratches, chips, or uneven fiber heights.

  2. Check for Flatness: The fiber ends should be perfectly flat with no convex or concave areas, which could impact light transmission.

  3. 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.
