摘 要：The Plastic Optical Fiber (POF) provides benefits compared to glass fiber. The best known POF is the step-index (SI) PMMA POF with a core diameter of 1 mm. It is simpler and less expensive than glass fibers. Large-core POF has greater flexibility and resilience to bending, shock, vibration, and it is easier in handling and connecting. The transmission windows of the POF are in the visible range. These advantages make POF very attractive for use in short-range communication and within in-building networks.
