    摘要： The invention disclosed is an optical fiber which includes a central core glass region with a first refractive index profile. The fiber includes a second core glass region adjacent to and surrounding said central region, said second region having a thickness that varies along an axial direction of said second region and having a second refractive index profile that differs from said first profile. Additionally, the invention includes an optical fiber preform that can be drawn into the above fiber. The invention also includes the method of making the above described optical fiber preform the aforementioned fiber is particularly useful as a dispersion managed fiber.

    摘要： Disclosed is a single mode optical waveguide fiber designated for compensating for positive dispersion in optical telecommunications systems. A key characteristic of the invention is that the novel dispersion compensating waveguide, viz., a waveguide having large negative dispersion, contains no dopants, such as fluorine, which lower the refractive index of silica. A refractive index profile design which includes a high refractive index center segment (5) surrounded by a plurality of alternating high (6, 10, 13) and low refractive index segments, provides a dispersion compensation fiber which has the optical properties required for the system to be compensated without sacrificing bend resistance, increasing splicing loss, or elevating polarization mode dispersion.
