US 2015/0086161 A1 · OPTICAL FIBER LINK WITH PRIMARY AND COMPENSATING OPTICAL FIBERS

Abstract

An optical fiber link that utilizes concatenated primary and compensating multimode optical fibers is disclosed. The primary optical fiber has a first relative refractive index profile with a first alpha value α40 of about 2.1 that provides for a minimum amount of intermodal dispersion of guided modes at a peak wavelength λP40 in the range from 840 nm to 860 nm, and has a first bandwidth BW40 of 2 GHz·km or greater. The compensating optical fiber has a second relative refractive index profile with a second alpha value α60, and wherein −0.9≦(α60−α40)≦−0.1, and a peak wavelength λP60 greater than 880 nm. The optical fiber link has improved bandwidth and data rates for first and second optical signals within first and second wavelength ranges, respectively.
