Fiber Connector Polishing Film – Precision Abrasive Film for Optical Polishing
Fiber connector polishing film is a critical consumable used in the final stages of optical connector termination to ensure high-quality, low-loss, and reliable fiber optic connections. It delivers a precisely controlled surface finish, enabling optimal transmission performance and long-term connector stability.
Whether in data centers, telecom, 5G networks, or aerospace, this polishing film is essential for polishing SC, LC, FC, ST, and MPO/MTP connectors.
Fiber connector polishing film is a precision-coated abrasive film designed for lapping and polishing fiber optic connector end-faces. It ensures:
Ultra-flat surface finishes
Controlled fiber protrusion or undercut
Enhanced optical return loss
Repeatable and consistent results across batches
Each film consists of micro-graded abrasive particles such as diamond, aluminum oxide, or silicon dioxide, bonded to a polyester backing that resists tearing and maintains uniform pressure distribution.
Precisely Graded Abrasives for consistent polishing
Uniform Backing Film ensures even pressure and geometry control
Available in PSA (Pressure Sensitive Adhesive) or plain backing
Compatible with manual and automated polishing machines
Fiber polishing films are available in a range of micron grades to support each polishing step:
Discs: 5", 6" , 8" for polishing machines
Sheets: 9" x 11", customizable sizes
Rolls: Continuous format for high-volume production
PSA Backing: Easy peel-and-stick application
MPO/MTP connector polishing
SC, LC, FC, ST single-fiber connector polishing
End-face geometry shaping and dome formation
