CONSTITUTION: This wide band multiple plastic optical fiber unit is composed of the multiple plastic optical fiber of nearly a circular shape in section filled and integrated with the resin having the refractive index lower by >=0.01 to <=0.04 than the refractive index of the resin of the coated fibers in such a manner that >=7 pieces of the coated fibers having the diameter of <=200μm of the individual coated fibers are discretely partitioned. The outside diameter of the optical fibers at the detector side terminal is set at a size of 0.1 to 0.9 times the outside diameter of the optical fibers at the light source side terminal.  Since a material having the refractive index approximate to the refractive index of the coated fiber materials is used for the sheath material of the multiple plastic optical fiber, light transmission at a high speed from 125 to 200MHz is made possible even at a length of 100m in the wider band than the band of the conventional plastic optical fibers.
