摘要： An optical transmission fiber has a refractive index profile with an area of increased index of refraction at the inner core of the fiber, an annular region positioned radially outward from the inner core with an index of refraction exceeding the index of the inner core, and at least a low dopant content region in a cross-sectional region between the inner core and the annular region. A low loss cladding layer surrounds the core region. The optical transmission fiber with this segmented core profile provides a high effective area, low non-linearity coefficient, nonzero dispersion, and relatively flat dispersion slope.

摘要： A bend-insensitive optical cable for transmitting optical signals includes an optical cable having a length, extending from an input end adapted to receive the optical signals, to an output end and including at least one single-mode optical fiber having a cable cut-off wavelength, of 1290 nm to 1650 nm. The at least one optical fiber is helically twisted around a longitudinal axis with a twisting pitch, for a twisted length, extending along at least a portion of the length, of the optical cable, wherein the twisted length and the twisting pitch are selected such that the optical cable exhibits a measured cut-off wavelength equal to or lower than 1260 nm. Preferably, the at least one fiber has a mode-field diameter of 8.6 μm to 9.5 μm. According to a preferred embodiment, the optical cable includes two optical fibers twisted together along the longitudinal axis, each of the two optical fibers having a cable cut-off wavelength of 1290 nm to 1650 nm.
