Plastic Optical Fiber, (POF), typically uses PMMA (acrylic), a general-purpose resin as the core material, and fluorinated polymers for the cladding material.In large-diameter fibers, 96 percent of the cross-section is the core that facilitates the transmission of light.lthough quartz fiber is widely used for infrastructures, POF has been called the consumer optical fiber. This is due to the fact that costs of POF, associated optical links, connectors and installation costs are low. It is being focused on the following fields in particular: 1  Digital home appliance interfaces.
