Optical fiber link with primary and compensating optical fibers

摘要: An optical fiber link that utilizes concatenated primary and compensating multimode fibers is disclosed. The has a first relative refractive index profile with alpha value α 40 of about 2.1 provides for minimum amount intermodal dispersion guided modes at peak wavelength λ P40 in the range from 840 nm to 860 nm, bandwidth BW 2 GHz·km or greater. second 60 , wherein −0.9≦(α −α )≦−0.1, P60 greater than 880 nm. improved data rates signals within ranges, respectively.
