| Abstract: | Three attenuation measuring methods for plastic optical fiber including the cut-back method, the insertion-loss method and the back-scattering method are introduced. The measuring principles and apparatus used in tests are presented in detail. The characteristics and the main problems that should be noticed in test procedures for three methods are emphatically discussed. |
