      1. the transmission point module class: transfer points module types of single-mode Fiber (Single Mode Fiber) and multimode Fiber (Multi Mode Fiber). Single mode fiber has a small diameter and can only be transmitted in a single mode at a given working wavelength. The transmission bandwidth is wide and the transmission capacity is large. Multimode fiber is a fiber that can be transmitted simultaneously in multiple modes at a given working wavelength. Compared with single mode fiber, the transmission performance of multimode fiber is poor. A). Single-mode Fiber (Single mode Fiber) : the general optical Fiber jumper is in yellow, the joint and protective sleeve are blue; The transmission distance is longer. B). Multi-mode Fiber (multi-mode Fiber) : the general optical Fiber jumper is expressed in orange, and some are expressed in gray, and the connector and protection apply to beige or black; The transmission distance is shorter. 

      2. The refractive index distribution class optical fiber can be divided into the hopping fiber and the graded fiber. The refractive index and the refraction of the protective layer are constant. At the interface between the fiber core and the protective layer, the refractive index is a step-change. The refractive index of the tween light fiber core decreases with the increase of radius and reduces the refractive index of the protective layer at the junction of fiber core and protective layer. The change of refractive index of fiber core is similar to that of parabola.
