Recently, fabric lighting devices or display devices using LEDs and optical fibers have been developed.

The optical fiber is an optical fiber in which a core having a high refractive index is disposed at a central portion and a cladding having a relatively low refractive index is disposed at an outer portion so that total internal reflection of light passing through the core occurs.

Such an optical fiber has an advantage of having a low loss rate of transmitted/received data due to very low energy loss and being hardly affected by external influences.

In addition, an optical fiber made of a light-transmitting plastic material for both the core and the cladding is called a plastic optical fiber (POF-Plastic Optical Fiber), and the plastic optical fiber has excellent flexibility compared to a general optical fiber made of glass, and is resistant to vibration or bending. strong on
