Fiber optic polishing paper is a specialized abrasive material designed to polish the endfaces of fiber optic connectors. It consists of a backing material coated with abrasive particles, such as silicon carbide or aluminum oxide, which are held in place by a binder. Thorlabs offers a family of products to assist customers who would like to terminate their bare fiber, including fiber polishing film for use with ceramic or stainless steel ferrules, polishing pucks, polishing plates, and termination kits. Polishing finalizes the connector endface and cleans the surface, which has a direct impact on optical performance parameters such as insertion loss. This article explains the process of optical fiber polishing, which is crucial for preparing high-quality fiber endfaces for applications like fiber connectors and fiber splices. It discusses the cases where polishing is superior to cleaving of fibers, for example, for achieving precise end angles. Fiber Optic Center features products to highlight attributes that deliver value to end-users and differentiate a product in the market.
