Abstract

Gigabit-data transmission has been made possible by using a graded index type plastic optical fiber with dopants. However, there remains the problem of bandwidth which decreases due to dopant diffusion. Recently, two kinds of dopants with a very low diffusibility, triphenylphosphate and tricresylphosphate, have been found. On the other hand, for a step index type POF (SI-POF), quite a degree of improvement in its bandwidth can be achieved by reducing the numerical aperture (NA) of the POF so that a megabit-data transmissions made possible. This low NA-POF has enough reliability for practical use. Furthermore, we succeeded in developing a new type of broadband POF consisting of a multiphase polymer, with an excellent heat resistance and a bandwidth performance much broader than that of the low NA SI-POF.
