A silica abrasive coating is applied to a polyester film substrate, producing a controlled, uniform cutting action that minimizes surface defects. At 4.125 inches in diameter, this disc is sized for standard fiber optic polishing fixtures. It is used by fiber optic technicians and telecommunications installers who require repeatable, low-loss connector end-face geometry on both single-mode and multimode connectors.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for the final polishing stage of fiber optic connector preparation, where surface quality directly affects insertion loss and back reflection performance. It is suited for use in production environments and field installation settings where consistent protrusion values and low defect rates are required across high volumes of connectors. The disc is rated for multiple uses, supporting higher throughput and lower per-connector cost in production workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilica abrasive on polyester film substrate for controlled final-stage polishing\u003c\/li\u003e\n  \u003cli\u003eMultiple-use construction supports high-yield, high-throughput polishing operations\u003c\/li\u003e\n  \u003cli\u003eConsistent protrusion values reduce rework and improve first-pass yield\u003c\/li\u003e\n  \u003cli\u003eLow insertion loss and low back reflection results on finished connectors\u003c\/li\u003e\n  \u003cli\u003eLow defect rate on polished end faces\u003c\/li\u003e\n  \u003cli\u003eAvailable in disc, sheet, and roll formats to suit different polishing equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a final-step polishing disc in fiber optic connector polishing systems that accept 4.125-inch diameter lapping film discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis disc is installed and used by fiber optic technicians following established connector polishing procedures. Ensure the polishing fixture and puck are clean and free of debris before mounting the disc. Follow the connector manufacturer's polishing sequence; this disc is intended for the final step only and should not be substituted for earlier coarser lapping stages. Inspect the disc surface between uses and discard when abrasive loading or surface damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSubstrate\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive\u003c\/strong\u003e: Precision-coated silica\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111900192\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010299763\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344142434610,"sku":"7010299763","price":2152.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527524.jpg?v=1782030104","url":"https:\/\/voomisupply.com\/products\/3m-7010299763-fiber-optic-polishing-disc-4-125-in","provider":"Voomi Supply","version":"1.0","type":"link"}
