Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To improve transmission distance, transmission speed and heat resistance by making the refractive indexes of a core and a clad uniform in a radial direction and providing a middle layer where the refractive index is distributed to be gradually reduced toward the clad side between the core and the clad. SOLUTION: The refractive indexes of the core C and the clad D are uniform in the radial direction, and the middle layer where the refractive index is distributed to be gradually reduced toward the clad D side and which functions to improve a transmission band due to such refracitve index distribution is provided between the core C and the clad D. Since the refractive index of the core C is basically uniform, the core C is homopolymer and dopant being the factor of the lowering of the heat resistance need not be added to the core C. Therefore, the core having the same transparency and the heat resistance as a step index type one, is obtained. On the other hand, the refractive index distribution in the middle layer M functions to uniformize propagting speed in respective modes, whereby mode dispersion is restrained and the transmission speed is improved.
