  • PHOTOCURABLE COATING COMPOSITION
    Publication number: 20110135269
    Abstract: Disclosed is a photocurable coating composition for an optical fiber. The photocurable coating composition can be used to produce an optical fiber having a low polarization mode dispersion (PMD) even by a non-spinning process. The photocurable coating composition includes a photopolymerizable urethane acrylate oligomer, a reactive monomer, a photoinitiator and an amine additive. Further disclosed is an optical fiber using the photocurable coating composition. The optical fiber has a polarization mode dispersion (PMD) of 0.1 ps/?km or less when produced by a non-spinning process.
