3M 7000028115 Silicon Dioxide Polishing Disc 5 Inch

Product Description

The 3M 7000028115 is a precision-coated silicon dioxide polishing disc designed for the final polishing step in fiber optic connector termination. The abrasive layer consists of silica particles applied to a polyester film substrate, delivering controlled material removal and consistent surface finish. At 5 inches in diameter, this disc is engineered for use in high-volume fiber optic assembly and termination environments. Technicians rely on it to achieve low insertion loss and controlled back reflection on polished connector end-faces. The multiple-use design supports increased throughput without sacrificing finish quality.

This disc is used in the final polishing stage of fiber optic connector preparation, where surface finish tolerances are critical. It is suited for both single-mode and multimode connector termination workflows in structured cabling, data center buildouts, telecom central offices, and fiber-to-the-premises installations. The polyester film backing provides dimensional stability during machine and hand polishing operations. It is sold individually and is also available in sheet and roll formats for operations requiring different fixture configurations.

Key Features

• Precision-coated silicon dioxide abrasive on polyester film substrate for consistent end-face finish
• Engineered for final-step fiber optic connector polishing to minimize insertion loss and back reflection
• Multiple-use construction supports high-yield, high-throughput polishing workflows
• Low defect rate on polished end-faces reduces rework and connector rejection
• Consistent protrusion values across the disc surface for repeatable results
• Available in disc, sheet, and roll formats to suit various polishing fixtures and volumes

Compatibility

Designed for use as a final-step polishing disc in fiber optic connector termination processes requiring a silicon dioxide abrasive film.

Installation Notes

Fiber optic polishing discs are installed by fiber optic termination technicians following the connector manufacturer's polishing procedure. Ensure the polishing film is seated flat and secure on the polishing puck or fixture before use. Inspect the disc surface before each use and replace when abrasive effectiveness diminishes or surface damage is visible. Follow all applicable industry polishing standards and connector manufacturer guidelines for end-face geometry requirements.
