Optical fiber, optical module and optical interface commonly used knowledge finishing(the third optical fiber knowledge)

- Jul 18, 2019-

Fiber optics are conductors of light waves. Fiber can be divided into single mode fiber and multimode fiber from the mode of light transmission.
In a single-mode fiber, there is only one mode of light transmission, that is, light is transmitted only along the inner core of the fiber. Because the mode dispersion is completely avoided, the transmission band of single-mode fiber is very wide and therefore suitable for high-speed, long-distance fiber transmission.
There are multiple modes of optical transmission in multimode fiber. Due to dispersion or aberration, this fiber has poor transmission performance, narrow frequency band, small transmission rate, and short distance.
