Abstract
The present invention relates to a multicore plastic optical fiber for optical signal transmission, which comprises a plurality of cores made of a transparent resin; first cladding layers made of a transparent first cladding resin having a lower refractive index than said core resin, each of said first cladding layers coating said each core; and a second cladding resin surrounding said cores with said first cladding layers, and having a lower refractive index than said first cladding resin. The multicore plastic optical fiber of the present invention is suitably applicable to optical signal transmission since it receives a large quantity of light and exhibits a small light loss upon bending.
