Overview
The 3M-EMSD Polish Film 5" Final Step is a professional-grade abrasive designed for the final finishing stages of fiber optic connector termination. This specialized film is engineered to provide a super-smooth end-face finish, which is critical for minimizing back reflection and ensuring optimal signal transmission.
These 5-inch discs utilize micro-graded abrasive particles bonded to a uniform 3 mil polyester backing. This construction ensures consistent, repeatable polishing results across multiple connector types, including ceramic, stainless steel, plastic, and composite ferrules. Designed for efficiency, this film helps maintain high first-pass yields in field and laboratory environments, significantly reducing the need for costly connector rework.
