Optical fiber

特許 権利維持 An optical fiber (or optical fibre) is a flexible, transparent fiber made of extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”,[1] to transmit light between the two ends of the fiber.[2] Power over Fiber (PoF) optic cables can also work to deliver an electric current for low-power electric devices.[3] The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics.
