These films are especially designed for use in factory or field applications. 3MTM Lapping Film Precisely graded minerals are coated on a high strength, 3 mil polyester backing to provide a uniform, consistent finish. Available in silicon carbide film for glass and epoxy removal, and in aluminum oxide for leveling and polishing steps. [. . . ] 3MTM Lapping Film 863X, 863XW / 869X, 869XW These products are precision coated on a 3 mil backing for the final step in polishing fiber optic connectors. 863XW has a higher mineral content than 863X, providing easier breakdown and faster polishing. 3MTM Polishing Film 291X, 491X, 591X / 298X, 498X, 598X Comprised of micron graded mineral that has been coated onto a fibrous (flocked) polyester film backing. Designed to break down into a slurry during use with water for MT-style fiber optic connectors. (961M/968M are available with no mineral coating. ) 3MTM Metal Bond Diamond Disc - 6MB1/ 6MB8 3M's most durable diamond abrasive is used for grinding the angle in angled connectors. The tough metal plated bond holds diamonds securely in place for extended use. Available in 6, 9, 15 and 30 micron grades, with or without PSA backing. 1 Selection Guide 3M's Technical Service Representatives suggest using these polishing guidelines for polishing ceramic singlemode or multimode fiber optic connectors. In the top chart, locate your connector type, then refer to tables A, B, and C below to select one of the options for each step. These recommended sequences provide typical starting points. Your actual sequences may vary depending on your polishing equipment and finish requirements.

Precisely graded minerals coated on a fibrous backing enable you to generate fiber protrusion and attain the proper ferrule geometry. 3M Polishing Film can provide: · Control of fiber protrusion · High throughput · Less cleaning than a slurry process · Low rejects Suggested Process for Polishing MT Fiber Optic Connectors 3M Technical Service Engineers recommend using the following sequences for polishing MT fiber optic connectors. These sequences provide typical starting points. Your actual process may vary depending on your polishing equipment and finish requirements. 3M Polishing Film Prod. 298X 298X 498X 598X Thermoset MT (singlemode or multimode) (singlemode) Step Remove Epoxy Step 2 Step 3 Step 4 Step 5 Micron Grade 15 3 3 1 0. 5 Mineral Silicon Carbide Silicon Carbide Silicon Carbide Aluminum Oxide Cerium Oxide Product I.
