MTP/MPO Fiber Optic Cables Polishing Solution - XYT Polishing Film

MTP/MPO Fiber Optic Cables Polishing Solution - XYT Polishing Film

Introduction

In fiber optic communications, the performance of MTP/MPO fiber optic cables hinges on the quality of the connector end-face finish. Achieving a superior finish ensures minimal insertion loss and return loss, making the polishing process crucial. XYT Polishing Films offer an advanced and reliable solution for polishing MTP/MPO connectors, delivering consistent and high-quality results. This article outlines the polishing parameters and techniques for achieving optimal performance with XYT Polishing Films.

Polishing Challenges and Solutions

1. Achieving Correct End-Face Geometry: The end-face geometry of MTP/MPO connectors is critical for maintaining low insertion loss and return loss. Achieving the correct geometry uniformly across multiple fibers is a significant challenge.

Solution: XYT Flocked Polishing Films are engineered with uniform abrasive distribution, ensuring consistent material removal while maintaining the desired end-face geometry. The flocked structure minimizes the risk of over-polishing, resulting in uniformity across all fibers.

2. Minimizing Scratches and Defects: Scratches and defects on the connector end-face can degrade signal quality and overall performance.

Solution: XYT Polishing Films utilize high-purity abrasives and advanced bonding technologies to achieve a smooth finish with minimal defects. The careful control of abrasive particle size and distribution ensures a consistent, high-quality polish.

Polishing Parameters

1. Grit Sizes and Abrasive Types: Selecting the appropriate grit size and abrasive type is crucial for each stage of the polishing process.

• Coarse Polishing:

  • Grit Size: 15µm (SC15)
  • Abrasive: Silicon Carbide
  • Purpose: Initial material removal and shaping.

• Intermediate Polishing:

  • Grit Size: 3µm (SC3)
  • Abrasive: Silicon Carbide
  • Purpose: Refining the surface and removing scratches from the coarse polishing stage.

• Fine Polishing (Fiber Height Adjustment):

  • Grit Size: 1µm
  • Abrasive: Aluminum Oxide Flocked Film
  • Purpose: Smoothing the surface and preparing for the final polish while adjusting fiber height.

• Final Polishing:

  • Grit Size: 0.5µm
  • Abrasive: Cerium Oxide Flocked Film
  • Purpose: Achieving a mirror-like finish with no defects.

2. Polishing Pressure and Speed: Controlled pressure and speed are critical to achieving consistent results without damaging the connectors.

• Pressure: 4-6 psi
• Speed: 150-200 RPM

These parameters ensure uniform material removal and optimal end-face quality.

Polishing Process

Step 1: Preparation

• Clean the connectors thoroughly to remove any contaminants.
• Inspect the connectors for any pre-existing defects.

Step 2: Coarse Polishing

• Use XYT SC15 15µm Silicon Carbide Polishing Film.
• Apply uniform pressure and maintain a consistent speed.

Step 3: Intermediate Polishing

• Switch to XYT SC3 3µm Silicon Carbide Polishing Film.
• Ensure even polishing across all fibers.

Step 4: Fine Polishing (Fiber Height Adjustment)

• Use XYT 1µm Aluminum Oxide Flocked Polishing Film.
• Achieve a smooth, pre-final finish on the end-faces while adjusting the fiber height.

Step 5: Final Polishing

• Use XYT 0.5µm Cerium Oxide Flocked Polishing Film.
• Achieve a mirror-like finish on the end-faces.

Step 6: Inspection and Cleaning

• Inspect the connectors using a microscope to ensure no scratches or defects are present.
• Clean the connectors thoroughly to remove any polishing residue.
