| 摘要 |
An optical fiber assembly comprising at least two plastic optical fibers and an embedding material, said plastic optical fibers being arranged substantially in parallel to each other and embedded in said embedding material, wherein each plastic optical fiber comprises a core of polymer having a refractive index, n1, and a cladding of a polymer having a refractive index, n2, wherein the refractive indices n1 and n2 satisfy the following relationship [I] n1-n2>0.01 [I] The optical fiber assembly is prepared by extruding from a spinneret a plurality of optical fibers having a core-cladding structure and an embedding material of a polymer in three layers of core, cladding and embedding material, according to a melt-spinning method; arranging the optical fibers in parallel to each other before solidification thereof; and bonding the optical fibers together through the embedding material.
