How does plastic optical fiber transmit light and what are its limitations in terms of distance?

Plastic Optic Fiber (POF) also called Pmma Fiber. It is made from plastic materials such as polymethylmethacrylate (PMMA) or polycarbonate. It is widely used in different purpose, such as Fiber Optic Lighting, decoration, industrial control, fashion and so on. POF is more safe than glass fiber because the material composition, construction. It is friendly to human body, special it can filter the blue lights which harmed to eyes.

POF transmits light through the process of total internal reflection. When light enters the core of the fiber at a certain angle, it is reflected off the internal walls of the core due to the difference in refractive index between the core and the cladding. This reflection allows the light to travel through the fiber without significant loss of intensity. The core of a POF typically has a larger diameter than glass optical fibers, which allows for easier coupling of Led Light Sources.

Attenuation refers to the loss of light intensity as light travels through the fiber. As far as you know, POF has a higher attenuation than glass fiber. because of the material and technology is different, some POF transmits light very short and the effect is fuzzy. Jiangxi Daishing POF use the top quality PMMA, and more 20 years technology experience, their POF is flexible and low attenuation. Their POF can transmit lights up to 20 meters, even the sparkle fiber, it can up to 15 meters. So it is very good at the decoration lighting.

In terms of distance limitations, POF is typically used for short-distance applications, such as local area networks (LANs), industrial automation, and automotive applications. POF can typically transmit signals over distances of up to 100 meters, although this can vary depending on the specific application and the quality of the fiber. Jiangxi Daishing POF Co.,Ltd is one of the drafter of Chinese National Communication Purpose POF Standard, and their standard is higher than the national standard.
