Plastic optical fiber (POF) is an optical fiber which is made out of plastic, is immune to electromagnetic wave radiation, noise , and has a good capacity of resisting distance. The POF cable has a higher bandwidth than other transmission material like copper, while it is energy-saving and environment protection. They are widely used in FTTH, CPN, LAN, industrial control, military communication and monitor system, consumer electronics, airborne equipment automobile intelligence and so on.

One of the most exciting developments in polymer fibers is the development of microstructured polymer optical fibers (mPOF), a type of photonic crystal fiber. POF fiber also has applications in sensing. It is possible to write Fiber Bragg grating in single mode and multimode POF. There are advantages in doing this over using silica fiber since the POF can be stretched further without breaking.

In large-diameter fibers, 96% of the cross section is the core that allows the transmission of light. Similar to the traditional glass fiber, POF transmits light (or data) through the core of the fiber. The core size of POF is in some cases 100 times larger than glass fiber.

Plastic fiber optic patch cords possess special characteristics that make this product an ideal solution for applications which traditional glass fiber products are not well suited. For applications requiring a very tight bend radius, POF products can generally bend to 25mm with no excessive attenuation. For visible light laser applications, POF assemblies can transmit the signal such that it is visible to the human eye, making the user aware of its attachment to an active laser and allowing them to avoid associated dangers. POF fiber optic patch cord products also have a very wide tolerance for scratching and contamination from the field. This tolerance allows the product to perform at acceptable level despite some compromise in physical condition.

For telecommunications, the more difficult-to-use glass optical fiber is more common, which has a core made of germania-doped silica. Although the actual cost of glass fibers are similar to the plastic fiber, their installed cost is much higher due to the special handling and installation techniques required. POF has been called the "consumer" optical fiber because the fiber and associated optical links, connectors, and installation are all inexpensive.
