The typical process involves stripping the fiber coating, inserting and securing the fiber in a ferrule with adhesive, and then polishing the end using a series of films with progressively finer grits. Finally, the endface quality is checked, for example with a fiber microscope. In order to allow better contact between the end faces of two optical fibers, the ferrule end faces of fiber optic patch cords are usually ground into different structures. The polishing fixture size is 174mm x 174mm, and it is designed to polish the volume fiber connector. You will receive comprehensive video and technical support from FOCC. Standard polishing methods are PC, APC, and UPC.
