| 摘要 |
The present invention relates to a perfluorinated plastic graded-index optical fiber 51 , including a core 52 of fluorinated polymer doped with a fluorinated compound, an optical cladding 53 in fluorinated polymer with an index less than that of said core 52 , surrounding said core 52 , as well as a strengthening layer 54 in polymer material, surrounding said optical cladding 53. The invention is remarkable in that the optical fiber 51 further includes a protective layer 55 in a photo-crosslinkable resin surrounding said strengthening layer 54 , and the polymer material of the strengthening layer 54 is a material different from that of the protective layer 55.
