Overview
The 3M-EMSD Aluminum Oxide (A/O) Polishing Discs are precision-engineered abrasive films designed for high-performance fiber optic connector termination. These 4-inch discs utilize micro-graded aluminum oxide abrasives bonded to a uniform polyester backing to provide consistent, repeatable surface finishes required for telecommunications and data center applications.
Engineered for versatility, these discs are suitable for polishing a wide variety of ferrule materials, including ceramic, stainless steel, plastic, and composite. By utilizing a non-slurry, dry-polishing process, these films help maintain a clean work environment while reducing total processing time and ensuring high connector yields.

Frequently Asked Questions
Are these discs suitable for both singlemode and multimode connectors?
Yes, these 0.3 micron aluminum oxide discs are suitable for the final polishing stages of both singlemode and multimode connectors.
Do I need to use water with these polishing films?
These films are designed for high-performance processing, which can often be performed without liquid slurries; however, follow your specific connector termination procedure for best results.
Can these be used on ceramic ferrules?
Yes, these discs are specifically recommended for polishing ceramic, stainless steel, plastic, and composite ferrules.
What is the primary benefit of the micro-graded abrasive?
The micro-graded abrasive ensures a uniform cut rate and surface finish across the entire disc, which results in more consistent connector back-reflection and insertion loss performance.
Are these compatible with standard 4-inch polishing plates?
Yes, they are designed to fit standard 4-inch fiber optic polishing fixtures.
