3M 7000044736 Polishing Disc 5 Inch Silicon Dioxide

Product Description

The 3M 7000044736 is a 5-inch diameter lapping and polishing disc designed for the final polishing step on fiber optic ceramic connectors. It uses a silicon dioxide (silica mineral) abrasive coated onto a 3 mil flexible backing, delivering consistent surface finish and controlled material removal at the end of the polishing sequence. The disc is engineered to hold tight protrusion tolerances, which directly supports low insertion loss and low back reflection in finished fiber connections. Fiber optic technicians and assembly professionals handling connector termination and end-face preparation are the primary users of this product.

This disc is suited for bench-top and automated fiber optic polishing machines across multiple equipment brands. It is used in telecommunications, data center cabling, and fiber assembly environments where end-face geometry and surface quality of ceramic ferrules must meet strict optical performance standards. The 5-inch diameter format fits a wide range of polishing machine platens used in both production and field termination workflows. It is sold individually and is available in larger format sheets and rolls for high-volume operations.

Key Features

• Silicon dioxide abrasive on a 3 mil backing delivers controlled, consistent material removal for final-step polishing
• Consistent protrusion values support repeatable connector end-face geometry across high-volume runs
• Low insertion loss and low back reflection results in finished ceramic ferrule connectors
• Compatible with many brands of fiber optic polishing machines for broad equipment flexibility
• Available in disc, sheet, and roll formats to match different production volumes and machine types

Compatibility

Designed for use with many different brands of fiber optic polishing machines that accept a 5-inch diameter polishing disc. Intended for use on ceramic fiber optic connector ferrules as the final polishing step.

Installation Notes

This disc is installed and serviced by fiber optic technicians and connector assembly professionals. Before mounting or replacing a polishing disc, power down the polishing machine and allow any rotating components to come to a full stop. Follow the polishing machine manufacturer's guidance for disc mounting, alignment, and fluid or film application. Dispose of used abrasive discs according to applicable facility waste handling procedures.
