Lapping Film for MPO MTP FC, LC, ST, SC/PC/APC Connector Polishing

XYT Lapping Film for FC, LC, ST, SC/PC/APC Connector Polishing

XYT Lapping Films are designed for high-precision polishing of various fiber optic connectors, including FC, LC, ST, SC/PC, and SC/APC connectors. These films are engineered to meet the stringent requirements of the fiber optic industry, ensuring that your connectors achieve a low insertion loss, smooth endfaces, and superior optical performance. Whether polishing PC (Physical Contact) or APC (Angled Physical Contact) connectors, XYT Lapping Films provide the accuracy and consistency needed for a perfect finish.

Key Features of XYT Lapping Films for MPO MTP FC, LC, ST, SC/PC/APC Connectors

• Precision Abrasives: Our lapping films are coated with diamond, aluminum oxide, or silicon carbide abrasives, depending on the polishing stage and connector type.
• High Durability: XYT films are engineered for extended service life, reducing the frequency of film replacements.
• Water-Resistant Backing: Polyester backing ensures stability and consistent polishing pressure, reducing the risk of slipping or warping.
• Various Grades: XYT offers different abrasive grades from 0.01µm to 30µm, allowing you to customize the polishing process based on the connector's type and polishing stage.
• Excellent Fiber Geometry Control: Achieve optimal fiber height, core dip, and apex offset control for better connector performance.
• Compatible with Manual & Automated Systems: XYT films work seamlessly with both manual polishing and automated polishing machines for FC, LC, ST, SC/PC, and SC/APC connectors.

Polishing Process for FC, LC, ST, SC/PC, and SC/APC Connectors with XYT Lapping Film

Step 1: Initial Epoxy Removal

• Film Used: XYT 9µm Diamond Lapping Film
• Purpose: Removes the excess epoxy and levels the surface of the connector ferrule.
• Technique: Apply moderate pressure in a figure-eight motion while using distilled water to avoid overheating and damage.

Step 2: Material Removal and Fiber Height Control

• Film Used: XYT 3µm or 5µm Diamond Lapping Film
• Purpose: To refine the fiber height and improve the surface of the fiber optic connector.
• Technique: Continue polishing with slight pressure and circular motions to ensure uniform fiber protrusion.

Step 3: Pre-Polishing for Smooth Finish

• Film Used: XYT 1µm or 0.5µm Diamond Lapping Film
• Purpose: To smooth the fiber ends and achieve uniform fiber height.
• Technique: Use light pressure with gentle circular motions to avoid over-polishing and ensure smooth, scratch-free results.

Step 4: Final Polishing for Ultra-Smooth Endface

• Film Used: XYT Final Polishing Film (optional for final smoothing)
• Purpose: For polishing the final surface and removing any micro-scratches, achieving a mirror-like finish on the fiber endface.
• Technique: Polish with minimal pressure and maintain gentle circular or figure-eight motions to prevent over-polishing.

Special Considerations for APC (Angled Physical Contact) Connectors

For SC/APC and LC/APC connectors that feature an 8° angle on the fiber endface, extra care is needed to maintain the angle precision and prevent damage to the fiber coating.

• Use XYT’s lapping films (e.g., 30µm or 15µm diamond).
• Opt for the Final Polishing Film to achieve a clean, smooth surface without disrupting the angled endface.
• Check the angled endface using an inspection microscope after each polishing step to ensure consistency.

Advantages of Using XYT Lapping Films for Connector Polishing

• Improved Fiber Geometry: XYT Lapping Films provide precise control over fiber height and core dip, leading to better alignment and optimal signal transmission.
• Enhanced Polishing Quality: Achieve smooth, defect-free, and polished fiber endfaces that meet industry standards for low loss and high performance.
• Durability: XYT films are built to last, allowing for longer polishing sessions with consistent results, reducing film replacement costs.
• Customization: XYT films come in various grades (from 0.05µm to 9µm) to suit different polishing stages and connector types, giving you the flexibility to tailor your process.

Applications

• FC Connectors: Used in high-performance optical communication systems requiring precise polishing for minimal insertion loss.
• LC Connectors: Common in high-density applications like data centers and telecommunications networks.
• ST Connectors: Popular in networking and test equipment requiring low-loss connectors.
• SC/PC Connectors: Essential for single-mode fiber and optical network components where polished connector quality ensures low return loss.
• SC/APC Connectors: Used in high-precision, low-return-loss environments where optical performance is critical.
