The quality of the finish or "polish" on your fiber optic connector endface is of critical importance. To achieve the proper endface surface, you must use a quality polish film, and polish the endface in successive steps with the proper size grit. We offer three varieties of diamond polish films, available in 1um, 3um, and 30um grit sizes. These 3"X 6" sheets are sold individually, and are color coded according to grit size. Using the proper products and procedures helps ensure that there will be no defects in your fiber and ferrule endfaces that could degrade the transfer of light between two connected fibers. This is especially critical for singlemode fibers, and our assortment of diamond polish films are designed to enable you to achieve the desired results on a consistent basis. In addition to fiber optic polish film, we offer a wide range of related products including polish discs or "pucks," polish plates, pads, and mats. We also have a complete line of fiber optic cleaners and other consumables required of the polishing process. Automated polishing machines and accessories are also available, including precision machine polishing discs, pads and lapping films.
