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. tic connector polishing? Fiber optic connector polishing is a very critical step after connectorization that utilizes an epo y termination technique. It discusses the cases where polishing is superior to cleaving of fibers, for example, for achieving precise end angles. Prepare the pull string and fiber by cleaning both ends with isopropyl alcohol. These traditional tech-niques involved a four-step process: epoxy removal, fer-rule forming, and preliminary and final polishing.
