POF uses a polymer (PMMA) as the core material that allows the transmission of light. Light is guided from one end to the other with minimal loss. It is also called consumer optical fiber because it is a low cost alternative that is easier to use than glass optical fiber. In comparison to traditional optical fiber, POF is much larger in diameter which results in lower data rates making it most suitable for high bandwidth signal transmission over short distances. That data transfer speed of 2.5GB/s isn’t as fast as glass optical fiber, but it is faster than copper wire.
Unlike glass, plastic fiber can easily be cut and bent to fit in hard-to-reach places and the larger core also allows for slightly damaged fiber to work. POF products are most commonly used in medical, automotive, home networks, as well as digital audio and video interfaces.
