    摘要： A radiation-curable, optical fiber coating composition has enhanced color stabilization and is formulated from a composition containing at least one radiation-curable oligomer or monomer. A concentration of urethane and ether linkages in the radiation-curable composition is such that a cured optical fiber coating formed from said radiation-curable composition exhibits a &Dgr;E of about 40 or less after being exposed for 96 hours to 150° C. and then for 144 hours to 180° C. Also provided is a radiation-curable optical fiber coating composition which is substantially urethane-free.

    摘要： Provided is an optical glass fiber assembly containing a matrix material and a plurality of coated optical glass fibers bound together by said matrix material, said matrix material having a swell index and/or glass transition temperature which provides the combination of properties of: (i) a swell index of a magnitude functionally capable of facilitating mid-span access to said optical glass fibers by a solvent stripping method of said matrix material from said optical glass fibers; and/or (ii) a glass transition temperature of a magnitude to facilitate end-access to said optical glass fibers by a heat stripping method of said matrix material from said optical glass fibers at an end terminus of said optical glass fiber assembly.
