3M 7100181744 Fiber Optic Polishing Disc 4.125 in

Product Description

The 3M 7100181744 is a silica mineral lapping disc designed for the final polishing step in fiber optic ceramic connector termination. The disc is coated on a 3 mil backing, delivering a consistent abrasive surface that controls connector protrusion values and minimizes insertion loss and back reflection at the connector interface. At 4.125 inches in diameter, it fits a wide range of polishing machines used in fiber optic termination work. Fiber optic technicians and telecom contractors rely on this disc as the finishing stage in a multi-step polishing sequence for PC, UPC, and APC connector end-face preparation.

This disc is suited for production and field environments where ceramic ferrule connectors require repeatable end-face geometry. The silica mineral abrasive and 3 mil film backing make it appropriate for the final polish pass, where surface quality directly affects optical performance. It is compatible with many brands of polishing machines, making it a practical choice for shops that run mixed equipment. Applications include data center termination, telecom central office work, and fiber optic assembly production lines.

Key Features

• Silica mineral abrasive on a 3 mil film backing for controlled final-step polishing
• Consistent protrusion values across ceramic ferrule connectors
• Low insertion loss and back reflection results at the connector end-face
• Compatible with many brands of fiber optic polishing machines
• Available in discs, sheets, and rolls to match workflow and equipment requirements

Compatibility

Designed for use with many brands of fiber optic polishing machines for final-step polishing of ceramic ferrule connectors.

Installation Notes

Installation and use of polishing discs should be performed by qualified fiber optic technicians familiar with end-face polishing procedures. Ensure the polishing machine is powered down and the platen is clean before mounting the disc. Follow the machine manufacturer's recommended mounting and pressure procedures. Inspect the connector end-face with a fiber inspection scope after polishing to verify surface quality before mating connectors.
