Abstract
Plastic optical fiber (POF) can be taken as short distance transmission system medium for replacing of coaxial cable because of its many excellent characteristics. The bandwidth characteristics of graded-index POF is strongly influenced by the differential mode attenuation (DMA). In this paper, a comprehensive bandwidth calculation model of POF is given. The analytical expression of DMA is fitted by eighth order polynomial from the experimental data, and is used for the calculation of fiber bandwidth. The frequency response function of graded-index plastic optical fiber(GIPOF) is calculated numerically under selective mode excitation condition, and the fiber bandwidth is studied. The calculated results indicated that the selective mode excitation could improve efficiently the fiber 3dB bandwidth. The influence of light source linewidth on fiber bandwidth is also investigated.
