| Abstract: | The homogeneity of single mode optical fibers made by the PCVD (Plasma Chemical Vapor Deposition)process is studied. Firstly, the loss coefficient, mode field diameter, cut-off wave length and geometrical properties for every part short fibers along axial direction are measureed respectively. The effect of fiber manufacturing process on the homogeneity of fiber is analysed from the chemical vapor deposition mechanism and the fiber drawing principle, respectively. The method of improving fiber homogeneity is promoted.This research has a significant role in making good performance single mode optical fibers. |
