Selecting the correct lapping film based on abrasive type, micron size, backing, and connector requirements is essential for achieving high-quality fiber optic polishing across MT, MPO/MTP, SC, LC, FC, ST, MU, and E2000 connectors.

Lapping film is a precision-coated abrasive material engineered for consistent, repeatable surface finishing in applications such as fiber optic polishing, electronics manufacturing, optics, metallurgy, and precision engineering.

Lapping film technology has become an essential component of modern ultra-precision finishing systems. As industries push toward tighter tolerances, smoother finishes, and contamination-free production, the ability to control surface quality down to the sub-micron level is no longer a luxury—it is a necessity.

Below are 11 key tips to help you get optimal results when using lapping film on TMT ferrules for MMC connectors.
