    摘要: The disclosed invention includes a composition for an optical fiber reel cover. The cured composition includes a polymer and a light inhibitor. The invention also includes a method of making an optical fiber reel cover with the inventive composition. The invention further includes a method to prevent photo-yellowing of coated optical fiber stored on a spool. The inventive reel cover is attached to a spool containing the fiber stored on a barrel of the spool. The cover conceals the fiber.

    摘要: An compound core optical waveguide fiber designed for high data rate or single channel or WDM systems which may include optical amplifiers. The waveguide is characterized by a core having two or three regions wherein the refractive index can be varied. The relative size of the regions may also be varied. By adjusting these variables, the desired mode field diameter, zero dispersion wavelength, dispersion slope and cut off wavelength were obtained. The optical properties are chosen to limit non-linear effects while maintaining low attenuation and acceptable bend performance. In addition, the residual stress within the waveguide is maintained at a low level to limit stress induced birefringence. The low residual stress in the uncoated waveguide, together with a dual coating system having selected moduli and glass transition temperatures results in low polarization mode dispersion.
