    Abstract: A single mode optical waveguide fiber having a refractive index profile comprising not less than four segments (16, 18, 20, 22) provides waveguide properties well suited to undersea or other long haul telecommunications systems. The novel refractive index profile is characterized by a core segment having a negative relative index, in which, the reference index is that of silica. Another feature of the invention is a cladding layer which contains refractive index increasing dopant at least in the cladding portion adjacent the outermost core segment.

    Abstract: An apparatus for transporting an optical signal is provided comprising at least two sections of optical fiber, a directional wavelength selector positioned between the at least two sections of optical fiber wherein the directional wavelength selector selectively blocks wavelengths propagating in a reverse direction, and a pump light emitting device optically coupled to the optical fiber.

    Abstract: A method for amplifying optical signals and an optical fiber amplifier for accomplishing the same. An optical fiber is coupled to a source of pump light and a signal gain level is correlated to a dispersion value of the optical fiber that corresponds to a local minimum power level of a cross-talk signal generated by four wave mixing. Optical signals are transmitted through the optical fiber while admitting sufficient pump light into the fiber from the source to attain the selected Raman gain level.

    Abstract: A method for amplifying optical signals and an optical amplifier (10) for accomplishing the same. An optical fiber (20) is coupled to a source of pump light (24) and a signal gain level is correlated to a dispersion value of the optical fiber (20) that corresponds to a local minimum power level of a cross-talk signal generated by four wave mixing. Optical signals are transmitted through the optical fiber while admitting sufficient pump light into the fiber from the source to attain the selected Raman gain level.
