    Abstract: Disclosed is an optical fiber (20) having a centermost laterally-elongated core (30) having a short dimension (a), a long dimension (b) and a first refractive index (n1), a moat (40) surrounding the central laterally-elongated core, the moat (40) having a second refractive index (n2), an outer dimension (c) and an outer dimension (d), and a cladding (50) surrounding the moat (40), the cladding (50) having a third refractive index (n3), wherein n1>n3>n2, a ratio of b/a is between 1.5 and 5.0, and a ratio of d/a is between 2.0 and 7.0. The fiber supports a single (one and only one) polarization within a Single Polarization Band (SPB). The fiber (20) may be coupled to optical components in apparatus where single polarization properties are desired.

    Abstract: Disclosed is an optical fiber (20) having a centermost laterally-elongated core (30) having a short dimension (a), a long dimension (b) and a first refractive index (n1), a moat (40) surrounding the central laterally-elongated core, the moat (40) having a second refractive index (n2), an outer dimension (c) and an outer dimension (d), and a cladding (50) surrounding the moat (40), the cladding (50) having a third refractive index (n3), wherein n1>n3>n2, a ratio of b/a is between 1.5 and 5.0, and a ratio of d/a is between 2.0 and 7.0. The fiber exhibits polarization maintaining properties in a PMB situated below (i.e., at shorter wavelength than SPB), such that beat length normalized to 1550 nm wavelength is preferably less than 10 mm. The fiber (20) may be coupled to optical components in apparatus where single polarization or polarization maintaining properties are desired.

    Abstract: A dispersion correction optical fiber includes a segmented core having a central core segment, a moat segment and, preferably, a ring segment. The refractive index profile is selected to provide a total dispersion minimum which is located within an operating wavelength band of the fiber. Most preferably, the dispersion value at the minimum is more negative than −400 ps/nm/km and greater than −1200 ps/nm/km at 1550 nm. Optical transmission systems including the present invention dispersion correction optical fiber optically coupled to various transmission fibers and dispersion compensating fibers are also disclosed, as is a method of operating the dispersion correction fiber wherein the minimum is located within the desired operating wavelength band.
