Abstract

The maximum information transmission rate of optical fiber communications is limited by the amount of the group velocity dispersion (GVD) at different wavelengths.¹ The highest theoretical rate is obtained at the zero dispersion point (typically 1.3 µm). However, optical fibers have the lowest loss in the 1.5-µm spectral region, which makes this region very attractive for optical communications, But significant negative GVD in this region (about — 15 ps/nm X km) limits the information rate due to the pulse broadening. Currently there is no effective technique for the compensation of the pulse broadening due to negative GVD in optical fibers.
