摘要： An inverse dispersion fiber (10) having a large effective area and a transmission system that incorporates the fiber for providing dispersion and dispersion slope compensation in a transmission fiber (3). The large-effective-area inverse dispersion optical fiber (IDF) (10) has a negative dispersion and a negative dispersion slope. The effective area, A eff , of the IDF (10) preferably is greater than approximately 31 micrometers squared (µm 2 ) at a transmission wavelength of approximately 1550 nm. The large-effective-area IDF (10) is suitable for use with super-large-effective-area (SLA) transmission fiber (3) for compensating dispersion in the SLA transmission fiber while reducing nonlinear effects between wavelength channels and cabling loss, which is especially advantageous in transoceanic and longhaul terrestrial systems. These nonlinear effects are inversely related to the effective area of the fiber (i.e., nonlinearities ~ 1/A eff ). Thus, an increase in the effective area of the fiber translates into a decrease in nonlinear interactions, which increases bandwidth capabilities and limits signal degradation. Furthermore, the large-effective-area IDF (10) of the present invention has very desirable transmission properties. The present invention also provides a transmission system (1) comprising at least one of the large-effective-area IDF optical fibers (10) of the present invention. Furthermore, A eff can be made large without having to increase the ratio, R a , of the diameter of the core to the diameter of the trench region (52).

摘要： A super-large-effective-area (SLA) optical fiber (10) that is suitable for communicating over a wide wavelength range and that, because of its large effective area, suppresses nonlinear effects that typically result from interaction between signal channels. The effective area, A eff , of the SLA fiber (10) of the present invention preferably is equal to or greater than approximately 80 µm 2 at a wavelength window around 1310 nm. Thus, the SLA fiber (10) of the present invention has a very large effective area and a very low cutoff wavelength. In accordance with the present invention, a variety of SLA fibers are provided that all have very large effective areas and desirable transmission properties. The large effective areas of the SLA fibers of the present invention enable nonlinear effects to be suppressed, as well as Stimulated Brillouin Scattering in analog transmission. The large effective areas also enable attenuation to be reduced. The result of suppressing nonlinear effects and reducing attenuation enable signals to be transmitted over long distances and over a broad bandwidth.
