Plastic Optical Fiber (POF) is a unique member of the optical fiber family. POF is made of Poly Methyl Methacrylate (PMMA), with a large core diameter (~1 mm) and high numerical aperture (NA 0.3 â 0.5).he following figure shows a comparison of a typical POF geometry compared to another well known optical fiber, the Multi Mode Glass Optical Fiber (MM-GOF). It is easy to appreciate the huge core diameter (20x) as well as the relativelly thin clad of POF compared to MM-GOF.
