What is optical fiber

Optical fiber is a conductor that transmits light waves. Optical fiber can be divided into single-mode fiber and multi-mode fiber according to the mode of optical transmission. In a single-mode fiber, there is only one fundamental mode of light transmission, that is to say, light is only transmitted along the inner core of the fiber. Because the mode dispersion is completely avoided, the transmission frequency band of single-mode fiber is very wide, so it is suitable for high-speed and long-distance fiber communication. In a multimode fiber, there are multiple modes of light transmission. Due to dispersion or aberration, the transmission performance of this fiber is poor, the frequency band is narrow, the transmission rate is small, and the distance is short.
